There is an error in the Bosch dishwasher, the faucet is on or blinking.

In the article “Dishwasher Indicators and Icons,” we described their meaning in detail.

If the “faucet” light on the control panel comes on (next to the water supply button), and the dishwasher is working normally, everything is fine. This means that water for washing has begun to flow into the car.
If you notice that the water supply indicator is on or flashing, while the machine beeps, and water does not enter the hopper, there are problems.

The explanation of this problem in the instructions sounds like this: there is no water supply. What could be the reason:

The inlet filter is clogged.
There were problems with the fill valve (broken, clogged).
Incorrect connection of the drain system. Self-draining occurs.
The water sprayer in the chamber is faulty.

All of the above signs may be indicated by code E15. If error E15 is on the PMM display and a tap is shown, there may be a problem with the Aquastop leak protection.

In various models of Bosch dishwashers, it can be full or partial.

Due to the leak, water enters the pan of the machine. With full protection, there is a float sensor that is triggered. As a result, a fault code is displayed on the display.

When the protection is partial, there is an absorbent sponge in the inlet hose. As soon as a leak occurs, the sponge is saturated with water and blocks access to the system. Read more about “Aquastop” for the dishwasher in a separate article.

Important! A large amount of foam can lead to leakage and tripping. Control the amount of detergent.

What does error E24 mean in a Bosch dishwasher?

If error E24 occurs in a Bosch dishwasher and the faucet is on, this usually happens either at the end of the wash before draining the water, or almost at the start, a couple of minutes after starting the unit. In both situations, the equipment stops and stops responding to commands.

The appearance of E24 indicates problems with water drainage. Moreover, new dishwashers most often signal a malfunction precisely at the beginning of the cycle, based on the results of quick testing of components. The old ones often give an error at the end of the wash.

Fixing error e22 in the dishwasher

Bosch models

As a rule, error E22 on a Bosh dishwasher occurs before the end of the wash cycle. Literally 5-7 minutes before the end of the process, the unit freezes, rinsing or drying of dishes stops, and combination e22 appears on the display. In rare cases, temporarily disconnecting the device from the power supply helps. The next time you turn it on, the error does not occur. But, after three or four cycles, the problem returns again.

Dishwasher filter

Error E22 on a Bosch dishwasher means the filters are clogged. But the secret lies in the fact that the food residues washed off from the dishes accumulated not on the external filters located in the unit’s tank, but much deeper. Code E22 indicates that the filters that remove dirty water from the tank are clogged. If error E22 alternates with code E24, there are most likely problems with the operation of the drain pump.

How to reset all Bosch dishwasher errors

One of the most popular in our country, the German manufacturer of household appliances Bosch, has provided for immediately resetting all previously accumulated errors in its units.
To reset the accumulated errors of the Bosch dishwasher and reboot it completely, you need to:

Open the unit door.
Start the “Power on” button.
Press the 1st and 3rd program buttons at the same time. Hold for 3 seconds.
Close the door and open it again.
Start the Reset button. Hold for 3 seconds.
Close the door and wait for the signal to finish washing.
Open the door. Turn off the car.

If you doubt the correctness of the actions taken, and do not want to once again expose yourself and the equipment that is irreplaceable in everyday life to risks, contact VseRemont24!

A certified technician will repair a dishwasher of any make and model, no matter what kind of damage occurs to it!

Models Siemens, Neff

In Siemens and Neff dishwashers, the meaning of the error code e22 is similar to the malfunction coded under the same combination in Bosch units. Experts explain the frequency of filter clogging with low motor power. Manufacturers do not equip dishwashers with powerful motors, as in washing units. And since the amount of food debris on plates and other kitchen utensils is much larger and larger in quantity than dirt on laundry, filters become clogged more often.

Error code

Often, code E22 appearing alternately with error E24 indicates a malfunction of the impeller in the motor. This could be due to:

chicken bone,
feather,
a small slice of onion or the rest of any food.

To return the Siemens, Neff dishwasher to functionality, you need to clean the water outlet hoses and make sure the motor is working properly.

Error e22 - program failure or malfunction?

Error E22 is a fault code in a Bosch car. More often, the message appears on the display closer to the end of the wash cycle. The program freezes and indicates a problem. Turning it on and off helps to resume operation, but not for long; after a few cycles the error occurs again. But, this time, already at the beginning of the cycle, or in the middle. Turning it off again saves the situation, but does not get rid of the problem. Error e22 (Fig. 1) appears alternately with error e24. Frequently restarting the software can only aggravate the problem, causing damage to the control unit. And this, in turn, will result in expensive repairs. Therefore, if the “reboot” did not lead to full restoration of functionality, and the error persists, you should immediately begin troubleshooting.

Error code e22 - how to understand and what to do?

The instructions for the Bosch machine decipher E22 as a dirty drain filter, and E24 as a clogged drain hose. Logic dictates that the filter needs to be cleaned (Fig. 2), since the blockage is impeding the flow of water. If this is the reason, then water will be found in the chamber tray, and the filter is clogged with food debris and/or fatty deposits. In this case, it is enough to clean it from dirt, if necessary, using a brush. But what if the filter turns out to be clean 50 percent of the time?

This means you need to start inspecting the drain hose, especially if errors E22 and E24 alternately appear on the display. First of all, identify the presence of kinks, creases and violations of integrity, and then debris and fatty deposits. If necessary, clean it or replace it. But it may happen that there are no blockages in the hose. Then the problem needs to be looked deeper. Deeper - it's in the pump. Most likely, a blockage has formed between the bushing and the impeller. Even a thread can paralyze the operation of the pump impeller and block the rotation of the diffuser (Fig. 3).

Can I fix the problem myself? It is possible, say service center specialists, but it should be done correctly and consistently. Step by step check all the elements of the dishwasher, the problems of which are signaled by E22.

The main thing you need to remember is that all work on equipment should be carried out after first disconnecting the power from the mains. The close proximity of water greatly increases the risk of electric shock, especially if the user who disassembles and diagnoses the unit is unqualified.

Repair sequence

Step 1: Unplug the dishwasher.

Step.2: Disconnect communications.

Step 3: Empty the dishwasher chamber from dishes, racks, and trays.

Step 4: Take out the water diffuser.

Step 5: Clean the debris filter.

How to troubleshoot a Bosch dishwasher

Start by checking “Aquastop” - it happens that the sensor simply sticks in the pan. Inspect the housing and hose connections for leaks. If everything is ok, do this:

Pull out the PMM plug from the socket.
Tilt the equipment from side to side until the float returns to its normal position.
Drain any water that has entered the pan.
Let the car dry.

Also inspect the hose. If you are convinced that the mechanical protection has activated, the inlet hose must be completely replaced.

Water supply problems

The error sign has disappeared, but the faucet is still on? Then you need to check the filling system.

Shut off the water supply by turning the inlet valve.
If you installed an in-line filter, remove it and check for blockages.
Disconnect the inlet hose from the housing. Rinse it under running water.
Take out the filter mesh. It often becomes clogged with rust and scale. If dirt cannot be removed with plain water, place the filter in a solution of water and citric acid.

The last thing to check is the intake valve. In Bosch dishwashers it is often located in the lower part of the housing.

Unscrew the fastening screws and remove the decorative panel from below - there is a valve behind it. Disconnect the wiring connectors.

Checking the electronic part of the valve is done with a multimeter. Connect its probes to the contacts of the part and measure the resistance. The working device should show from 500 to 1500 Ohms.

To check the mechanical part, apply operating voltage (220 V) to the valve and see whether the membrane opens or not. In case of any malfunctions, the element must be replaced. Unscrew the fastening screw, remove the old part and install the new one.

When purchasing an inlet hose, make sure that the markings match the old model. Otherwise, you may select an inappropriate element.

Additionally check the nozzles:

Open the hopper door.
Pull out the baskets.
Remove the upper and lower spray arms from their place.
Rinse under the tap. The injectors can be cleaned with a toothpick.

Sometimes the cause of such problems can be a leakage sensor. It may have failed or is sending incorrect signals to the module. Then you need to carry out diagnostics and, if necessary, replace the sensor.

Troubleshooting water supply problems

It often happens that the error code does not appear or has disappeared, but the faucet still lights up. In this case, you need to pay attention to the water supply line. To do this you need to do the following.

Close the filler valve.
If there is a flow filter, remove it and check for blockages.
Disconnect the filler hose and clean it thoroughly, then rinse under running water.
Remove the filter mesh, which often becomes clogged with scale and rust. Particularly stubborn stains can be removed with a citric acid solution.

At the final stage, the condition of the water intake valve is checked. For most Bosch PMM models, this structural element is located in the lower part of the body. To dismantle it, unscrew the mounting screws and remove the decorative trim. It is also important to remember the need to disconnect the electrical wiring plugs from the device. Checking its electronic component is carried out by determining the resistance using a multimeter.

Normal values typically range from 500 to 1500 ohms.

To determine the condition of the mechanical part of the valve, it will be necessary to apply a voltage of 220 V to it and make sure that the membrane operates. If any malfunctions are detected, the device is replaced with a new one. Do the same with the inlet hose. Another important point is checking and cleaning the nozzles, for which you should:

open the hopper door;
remove the basket;
remove the upper and lower sprinklers;
clean the nozzles (you can use a regular toothpick) and rinse them with running water.

In addition to all of the above, problems with water supply may be associated with a sensor that monitors leaks.

It may fail or send incorrect signals to the control module.

Water supply problems

If the "Tap" light comes on, there is a good chance that there is a problem with either the flow-through inlet filter or the inlet valve. If this model of Bosch dishwasher has a display, the machine may also display error E01. What needs to be done?

Turn off the tee tap so that no more water flows into the machine.
If there is an additional flow filter on the hose, then it should be unscrewed, disassembled and thoroughly cleaned of water stone and dirt.
Next, you need to remove the inlet hose, pull out the standard flow filter (installed at the entrance to the dishwasher), clean and rinse it.

If the above steps do not resolve the problem, you will have to check the filling valve. First you need to remove the lower decorative panel from the Bosch dishwasher. On the front left at the very bottom you will see a fill valve with two contacts and wires going to it. We disconnect the wires, arm ourselves with a multimeter, and check the resistance. If the filling valve is faulty, it must be replaced. You can read more about malfunctions related to the water supply in the article Water does not flow into the dishwasher.

Self-draining

The Faucet indicator may show signs of life if the drain hose is not connected to the sewer properly. It would seem, how does drainage affect the flow of water into the dishwasher? It turns out the relationship is very direct. When the dishwasher fills with water, but it constantly flows by gravity into the drain, the control module can recognize this phenomenon as an inability to fill the water to the desired level. After this, the “Crane” indicator begins to blink and the machine stops working.

In almost all cases, problems with self-draining occur in dishwashers that have only recently been in use. Why does the dishwasher drain on its own? Because it is not connected to the sewer properly. It is necessary to immediately stop the dishwasher and make a normal connection. You can read about how to do this correctly in the article How to connect a dishwasher to water supply and sewerage?

For your information! The problem with an incorrectly connected drain hose can be fixed with your own hands within 10 minutes.

"Aqua Stop" triggered

If your Bosch dishwasher is equipped with a leakage protection system, then it is very likely that this system has worked. When “Aqua Stop” is triggered, the dishwasher automatically shuts off the water, often generating a system error with a certain code. The error code may not pop up, but the “Tap” indicator will definitely start blinking. What to do in this situation is described in the article Aquastop hose for a dishwasher, read it and everything will become clear to you.

In conclusion, we note that a burning or blinking “Tap” indicator on Bosch dishwashers most often indicates a malfunction. We tried to review the nature of these malfunctions and their causes in the framework of this article. We hope you find this information useful, good luck!

Thank you for the article. However, having encountered the same problem, I started looking for an answer on the Internet and discovered that it was quite popular advice to pour up to 10 liters of water into the working chamber of the machine. After I checked and cleaned the filters and did not achieve anything, I decided to use this advice. I poured water inside the car (mine fit about 4 liters) and turned it on. The machine (model Bosch spv-63m50ru) finally started working! And now it works flawlessly.

Is it possible to get a technical explanation for this shamanism?

Perhaps, thanks to the water, some lopsided float came loose?

Thanks for the advice - it helped!

Cleaned the filter, didn't help. We saw Andrey’s advice and decided to take advantage of the recommendation. We poured 6 liters of water into the dishwasher, turned on the eco program, everything worked out. The tap went out. Everything worked as before!

Bosch dishwasher lights are on

Warning signals in a Bosch dishwasher - the indicators glow or blink: faucet or brush, signaling a problem/failure that has occurred in the dishwasher:

1. The faucet indicator in the Bosch dishwasher is on. The water supply to the dishwasher stops and a humming noise may be heard.

Check whether the water supply to the apartment has been turned off or whether the water supply pressure has decreased - a minimum of 10 liters per minute is required.
Forgot to open the water supply tap to the machine.
The water supply hose is bent or kinked.
The filter in the supply hose is clogged - you need to turn off the water and clean it.
Clogged filters inside the dishwasher.
A clogged drain hose or a dish is blocking the sump pump cover.

The "faucet" error is on on the Bosch dishwasher

Most users prefer to use a dishwasher without worrying about indicator symbols. Errors and other subtleties. As long as the dishwasher works properly and performs its function.

Bosch dishwashers are equipped with a self-diagnosis system. If any problems or deviations in operation are detected. Lights or errors may appear on the dishwasher display. One of these indicators. Faucet icon.

Let's note right away. Which depends on the error and generation of the Bosch dishwasher. The faucet indicator may either light up or flash. If there is a digital display. The faucet may flash, and a malfunction error will appear on the digital display.

What to do if the tap on your Bosch dishwasher is on?

Unfortunately, even the most reliable equipment produced by renowned manufacturing companies is not immune from malfunctions. So, after many years of uninterrupted operation, a German brand dishwasher may fail. Moreover, all problems with modern models of such household appliances are accompanied by a corresponding indication. Such alerts allow you to determine the causes of breakdowns and eliminate them in a timely manner. That is why it is important to know what to do if the faucet on your Bosch dishwasher is on fire. It is worth noting that this unpleasant situation is rather sparsely covered in the attached instructions.

Causes of faucet fires

This problem is given little attention in the user manual, so we decided to devote this section of our website to a detailed study of all the important points related to the occurrence of the error.

According to the instructions, the decoding is as follows: “Tap” lights up (or blinks) if water intake is not fully ensured. The explanation is too sparse, without even explaining the user’s actions in this case, right? But you need not only to diagnose the breakdown, but also to fix it. We list the breakdowns that activate the indicator on the PMM control panel:

The filter located at the inlet valve is clogged.
The filler valve is broken.
The drain hose is connected incorrectly, which causes back drainage.
The AquaStop leakage protection system has activated.

If you have problems recognizing icons and codes in a Bosch dishwasher, read a separate article with a breakdown of the symbols.

In all of the above situations, the water supply indicator may behave differently:

if the inlet filter is clogged and the liquid does not penetrate into the device or enters there slowly enough, the light may light and flash;
if the intake valve does not operate, then the sign simply lights up;
if self-draining occurs, the faucet blinks;
The light bulb behaves in approximately the same way if “Aqua Stop” is activated.

Let's look at the causes and ways to eliminate all these breakdowns.

On a note! If a problem occurs, error e15 may appear on the Bosch PMM display and a tap may be shown.

The faucet indicator is on

According to the instructions for Bosch dishwashers. In cases where the indicator just lights up. This designation indicates that it is possible:

Water supply hose is kinked
Water tap closed
The filter in the supply hose is clogged
Filters are clogged or clogged
The drain hose is clogged or kinked
Siphon connection is closed
The bilge pump is blocked or the pump cover is not closed tightly

In cases of clogged or kinked hoses. You can fix the problem yourself. It is also not difficult to wash the filters and filler valve screens. If the problem is found and fixed. All you have to do is restart the dishwasher. In any washing mode, it should complete the washing cycle without errors.

Quite often rechecking all hoses and filters. The dishwasher refuses to start and the faucet light comes on. In such cases. There is usually a problem with the dishwasher itself. Which cannot be eliminated by cleaning the filters.

The faucet indicator is flashing

Things are a little different in the Bosch dishwasher, where the faucet indicator blinks. This designation is associated with the presence of a more serious malfunction.

According to the instructions: There was probably a technical malfunction. Turn off the device using the button and turn it on after a while. If the problem occurs again. Turn off the water, unplug the appliance and call a specialist.

As practice shows, the faucet indicator often flashes in conjunction with error E15. In this case, you need to turn off the supply valve and contact a specialist.

It is worth understanding that if the faucet indicator (water supply indicator) lights up or flashes in your Bosch dishwasher. This should not be regarded as a clear problem with the water supply. The main designation of the faucet. Notify the owner that there is a malfunction. It is necessary to turn off the water supply tap and contact a service center to repair the dishwasher.

Problems with water intake

When the digital display shows "Tap", there is a high percentage that the problem is with the flow-through inlet filter system or inlet valve. If the model has a screen, the error code “E01” or another corresponding to your PMM model may light up on it. How to proceed? Proceed as follows:

Close the tee valve to block the flow of water into the equipment.
If there is another flow filter on the hose, unscrew it and at the same time disassemble it, clean it from deposits and blockages.
Remove the inlet hose, remove the factory flow filter, which is installed at the very entrance to the machine body, clean and wash it under running water.

If the procedures performed did not bring a successful result and the Bosch dishwasher displays an error, the faucet lights up on the screen, the equipment beeps or shows other signs of failure, the filling valve needs to be checked. Proceed like this:

Remove the front panel.
In front on the left side at the bottom there is a valve, 2 contacts and wiring going to it.
Disconnect the wires, take a tester and measure the resistance.
Having found out from the tester's indicators that the part is broken, replace it with a new one.

What to do when self-draining?

If the faucet indicator lights up, the hose may not be connected correctly to the sewer system. There is a direct relationship between draining and collecting water into the machine - when filling, the equipment draws water, but due to incorrect placement of the hose, the liquid flows into the sewer pipes. Electronics can recognize such a process as a problem with the dial, which is why the light blinks or the error lights up. In this case, the equipment completely blocks the work - it is impossible to operate it in this mode.

Almost always, such cases involve dishwashers that were recently purchased and connected independently - without the help of a specialist. If this is your case, disconnect the equipment from the power supply and connect it according to the rules or invite a specialist.

Also read about connecting to a dishwasher in a separate article.

The faucet indicator on the Bosch dishwasher is on or blinking, what should I do?

What to do if the faucet indicator on a Bosch dishwasher is on or blinking, how to reset the error? The article describes in detail a popular breakdown of a Bosch dishwasher, the causes of the breakdown and popular solutions.

Don’t immediately panic and rush to call the service center technicians.

If the indicator lights up brightly and the dishwasher is functioning normally, water has begun to fill.
If the operation of the equipment has stopped, characteristic sound signals in the form of a squeak are heard, the indicator lights up brightly or flashes - specialist intervention is necessary.

The “faucet” is located next to the water supply button. When the light signal goes off, it means there is a problem with the water supply. This malfunction may occur due to:

intake valve clogged;
failure of the filling valve (clogged, broken, etc.);
incorrect connection of the drainage system
Leakage in the dishwasher tray.

The error code displayed on the dashboard – E15 – can also indicate the above problems. The code and flashing indicator can warn the owner of household appliances about problems that have arisen in the Aquastop leakage protection system. If there is a leak in the system, water flows into the pan. The float sensor gives a signal to the system and an error code appears on the display.

You can try to fix the problem yourself, but this will require certain knowledge and skills. Wrong actions can only make the problem worse.

Water in the pan. Unplug the dishwasher. Tilt the body of the equipment so that the float is in its normal position. Drain the water from the pan. Leave the equipment for a while so that the accumulated moisture can dry out.
Problems with water supply. turn off the water supply. To do this, you will need to close the fill valve. Check the filters in the system for blockages. Check the inlet hose for kinks and blockages. If necessary, disconnect it from the system and wash it with water. Check the inlet valve.
Spray. Open the container door and remove the trays. Remove the upper and lower spray arms and wash them.
Leak sensor. A faulty sensor may provide the system with incorrect data and the control module does not start flooding. The failed sensor will need to be replaced.
Self-draining In the Norm, the drain hose is located from the floor at a level of 45 cm. Compliance with this standard and the correct bending of the hose will minimize the risk of self-draining water into the sewer during flooding.

You should not try to fix the problem yourself. Contact specialized service centers for help. Experienced craftsmen will quickly fix the problem with water filling.

Why does the indicator light up?

If you find that the indicator with the faucet sign is on on the panel of the Bosch dishwasher, but the dishwasher is operating as usual, it means that water has started flowing into the machine, and the alarm is false. If, when the indicator is flashing, the dishwasher makes strange sounds, similar to a squeak, and water does not fill into the hopper, it means that the part has failed or a malfunction has occurred.

It is worth understanding that the “tap” sign means there is no water supply, the following factors may be the reason for this behavior:

intake filter clogged;
malfunction of the fill valve due to breakage or blockage;
incorrect connection of the drainage system, due to which it occurs on its own;
The water sprayer is not working properly.

All these signs of a malfunction of the Bosch washing machine fit into the short error code E15. In addition, the tap may indicate a failure in the Aquastop leak protection mode. It often happens that due to the fault of the user, a leak occurs and the protection is triggered. It is important to control the amount of detergent you add to the nest.

Depending on the Bosch model, protection against leaks can be complete or partial. The pan of the machine is filled, and the sensor that controls the water level is triggered. As a result, you see an error code on the display. If the protection is partial, then when a large amount of water forms, the absorbent sponge becomes saturated with liquid and closes access.

"Dishwashing" indicator.

Specify at what moment the indicator blinks? Does the machine work properly?

It happened to me when I started the car, I pressed Start, and then I wanted to change the program. If you close the machine, it will continue to work. But if you still want to change the program, press and hold the Start button for 3 seconds (stop the current cycle), then turn off the machine, turn it on and set the desired program. Hurray.

Modern dishwashers have quite a lot of different indicators, which owners pay attention to infrequently, but in vain. The indicator can promptly indicate a particular problem, especially if it does not just light up, but blinks. Let's say the brush on a Bosch dishwasher is blinking. What does this mean? Maybe it’s a breakdown, a small glitch, or the behavior of the “home assistant” that doesn’t mean anything at all? Now we will try to figure this out.

How to troubleshoot a Bosch dishwasher

Start by checking “Aquastop” - it happens that the sensor simply sticks in the pan. Inspect the housing and hose connections for leaks. If everything is ok, do this:

Pull out the PMM plug from the socket.
Tilt the equipment from side to side until the float returns to its normal position.
Drain any water that has entered the pan.
Let the car dry.

Also inspect the hose. If you are convinced that the mechanical protection has activated, the inlet hose must be completely replaced.

Water supply problems

The error sign has disappeared, but the faucet is still on? Then you need to check the filling system.

Shut off the water supply by turning the inlet valve.
If you installed an in-line filter, remove it and check for blockages.
Disconnect the inlet hose from the housing. Rinse it under running water.
Take out the filter mesh. It often becomes clogged with rust and scale. If dirt cannot be removed with plain water, place the filter in a solution of water and citric acid.

The last thing to check is the intake valve. In Bosch dishwashers it is often located in the lower part of the housing.

Unscrew the fastening screws and remove the decorative panel from below - there is a valve behind it. Disconnect the wiring connectors.

Checking the electronic part of the valve is done with a multimeter. Connect its probes to the contacts of the part and measure the resistance. The working device should show from 500 to 1500 Ohms.

When purchasing an inlet hose, make sure that the markings match the old model. Otherwise, you may select an inappropriate element.

Additionally check the nozzles:

Open the hopper door.
Pull out the baskets.
Remove the upper and lower spray arms from their place.
Rinse under the tap. The injectors can be cleaned with a toothpick.

How to fix the problem yourself

Start diagnostics by checking the Aquastop mode. The sensor could be stuck in the pan. Also inspect the hoses and housing for leaks. If you do not find any external damage, then you should remove the dishwasher plug from the socket. Try tilting the technique from side to side so that the float returns to its original position. If water drains into the pan, remove it. Let the machine dry and only then resume work. Also pay attention to the external condition of the drain hose. When the mechanical protection is triggered, this part must be replaced with a new one.

Leakage protection triggered

Not all equipment is equipped with the AquaStop function, but the latest models from the middle and high price categories always provide this level of protection. When the system is activated, the machine stops drawing water and displays an error, but the faucet blinks more often. Elimination of the failure is described in detail with photo instructions in the corresponding publication dedicated to the Aqua Stop hose.

Now, if problems arise with the water supply button and the faucet light, you will definitely not be confused and will take the necessary actions.

If your Bosch dishwasher signaled an error in the form of a burning faucet? Don't know what to do? It's time to refer to the instructions. Or look at the description of the problem on the network. The faucet-shaped indicator is correctly called the “Check water supply” indicator.

Most users prefer to use a dishwasher without worrying about indicator symbols. Errors and other subtleties. As long as the dishwasher works properly and performs its function.

Reasons for error E 24 in a Bosch dishwasher

The E24 icon on the display can appear due to both minor failures and serious malfunctions. Most often the problem is caused by:

clogged filters - if the system is clogged with debris and grease, the water drains too slowly or stops altogether, and the dishwasher gives an error;
twisting of the drain hose; when using the machine for a long time, it can break or bend in some places, which impairs the quality of liquid drainage;
the pump is clogged, deposits can accumulate on the impeller blades, and hair often gets wrapped around it;
electronic failure, even if the dishwasher is in full working order, its control unit may produce random errors.

Error E24 is an indicator of problems with drainage. Important! In rare cases, error E24 appears in a Bosch dishwasher due to complete failure of the electronic system. But before you send the unit for service, in any case, you can try to fix it yourself.

For what reasons does the “faucet” on the panel light up or blink?

In the article “Dishwasher indicators and icons” we described their meaning in detail.

If the “faucet” light on the control panel comes on (next to the water supply button), and the dishwasher is working normally, everything is fine. This means that water for washing has begun to flow into the car.
If you notice that the water supply indicator is on or flashing, while the machine beeps, and water does not enter the hopper, there are problems.

The explanation of this problem in the instructions sounds like this: there is no water supply. What could be the reason:

The inlet filter is clogged.
There were problems with the fill valve (broken, clogged).
Incorrect connection of the drain system. Self-draining occurs.
The water sprayer in the chamber is faulty.

All of the above signs may be indicated by code E15. If error E15 is on the PMM display and a tap is shown, there may be a problem with the Aquastop leak protection.

In various models of Bosch dishwashers, it can be full or partial.

Due to the leak, water enters the pan of the machine. With full protection, there is a float sensor that is triggered. As a result, a fault code is displayed on the display.

Important! A large amount of foam can lead to leakage and tripping. Control the amount of detergent.

Causes

In situations where a Bosch dishwasher displays an error code on its display and the faucet is blinking, it is initially important to determine the reason for such an indication. This may be accompanied by additional signs of trouble. For example, the pump hums, but the PMM does not work (does not draw and/or drain water). In any case, the self-diagnosis system warns the user of problems.

In accordance with the manufacturer's instructions, the faucet lights up or flashes if the full water intake into the washing chamber is not ensured. It is worth noting that such an explanation, combined with the absence of any recommendations, is unlikely to help quickly find a way out of a difficult situation. This involves both identifying the causes of the malfunction and carrying out the appropriate repair work.

An image of a faucet on the control panel of a Bosch dishwasher may appear in the following cases.

The filter element located directly next to the inlet valve of the main line is clogged.
The water supply valve has failed.
The dishwasher is not connected to the drain properly. In such cases, you have to deal with a phenomenon called “backflow”.
The AquaStop leak protection system has activated.

If you have any difficulties deciphering the indicators and error codes of equipment from the legendary German brand, you can use the operating instructions. It is also important to take into account that for all the reasons listed above, the indicator in question may behave differently.

The icon is constantly on or blinking - if the inlet filter is clogged, water does not enter the PMM chamber at all or water intake occurs too slowly.
The faucet lights up constantly - it is out of order and the inlet valve does not work.
The indicator blinks constantly - there are problems with the drainage. The icon will behave in a similar way when the leakage protection system is activated.

Additional evidence of the presence of certain technical problems is code E15. If it appears on the dishwasher monitor along with the faucet, then Aquastop may be the source of trouble. It is important to note that depending on the model of Bosch equipment, it can be either partial or complete. If a leak occurs, then water appears in the pan of the machine, as a result of which the float sensor is activated, and a corresponding notification is displayed on the display.

An element of the partial protection system is an absorbent sponge located directly in the filling sleeve. If there is a leak, it will begin to absorb water and cut off its supply to the system.

It should also be taken into account that an excessive amount of foam when washing dishes often causes leaks, and, consequently, the activation of the AquaStop function and the display of error messages.

How to troubleshoot a Bosch dishwasher

Start by checking “Aquastop” - it happens that the sensor simply sticks in the pan. Inspect the housing and hose connections for leaks. If everything is ok, do this:

Pull out the PMM plug from the socket.
Tilt the equipment from side to side until the float returns to its normal position.
Drain any water that has entered the pan.
Let the car dry.

Also inspect the hose. If you are convinced that the mechanical protection has activated, the inlet hose must be completely replaced.

Water supply problems

The error sign has disappeared, but the faucet is still on? Then you need to check the filling system.

Shut off the water supply by turning the inlet valve.
If you installed an in-line filter, remove it and check for blockages.
Disconnect the inlet hose from the housing. Rinse it under running water.
Take out the filter mesh. It often becomes clogged with rust and scale. If dirt cannot be removed with plain water, place the filter in a solution of water and citric acid.

The last thing to check is the intake valve. In Bosch dishwashers it is often located in the lower part of the housing.

Unscrew the fastening screws and remove the decorative panel from below - there is a valve behind it. Disconnect the wiring connectors.

Checking the electronic part of the valve is done with a multimeter. Connect its probes to the contacts of the part and measure the resistance. The working device should show from 500 to 1500 Ohms.

When purchasing an inlet hose, make sure that the markings match the old model. Otherwise, you may select an inappropriate element.

Additionally check the nozzles:

Open the hopper door.
Pull out the baskets.
Remove the upper and lower spray arms from their place.
Rinse under the tap. The injectors can be cleaned with a toothpick.

Self-draining

Is the faucet indicator flashing? Then check that the dishwasher is connected to the drain correctly:

The drain hose should be located at a distance of 45 cm from the floor.
It is necessary to create the correct bend to avoid self-draining into the sewer.

The control board recognizes the problem as insufficient water level in the tank. That is, in the allotted time the machine was unable to collect enough water.
