Bosch dishwasher faucet error how to fix

Users of Bosch dishwashers often encounter a situation where a “faucet” indicator is drawn on the control panel of the dishwasher. If the “faucet” lights up only when water is drawn, and the Bosch dishwasher is working normally, then do not worry, the “faucet” indicator means that the Bosch dishwasher is drawing water.

It’s a completely different matter when the blinking faucet is accompanied by problems. This is what Bosch dishwasher users complain to us about in this situation:

The machine does not draw water, the “faucet” indicator blinks, and the dishwashing does not start.
The dishwasher periodically does not complete the program and the faucet icon lights up.
Bosch with a display shows an error on the screen and the “faucet” lights up or flashes. Most often, the blinking indicator is accompanied by errors E15, E24, E25. In Bosch dishwashers without a display, in addition to the “faucet”, other indicators may light up.

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.

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.

Kinked or clogged hose

Inspect the supply (fill) hose of the dishwasher and route it without kinks . At the same time, check the drain hose for kinks.

Step-by-Step Guide: How to Check Hoses for Kinks

The hose may be kinked. Make sure the cold water inlet hose and waste water drain hose are not kinked.

Move the device a little and straighten any visible creases; to do this, route these hoses without creases or kinks.

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.

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. How to properly connect a dishwasher, read in a separate article. Monitor and care for your equipment. Read about how to clean your dishwasher.

Now you know what to do if the “faucet” indicator lights up on the control panel of your Bosch dishwasher. A video on the topic will help you deal with the problem:

Prevention

Preventing a breakdown is sometimes easier than fixing it:

Hard water comes out of the tap. It must be smoothed using special 3in1 products. This prevents the formation of scale and deposits on dishwasher parts. This means the hoses and drainage system will last longer.

To prevent device errors, special products designed to effectively soften hard water will help.
Thoroughly clean dishes of food residues before loading them into the machine. Otherwise, the filter will quickly become clogged, leading to breakdown and water leakage.

If the filters become clogged, the water does not circulate well during washing, the washing tank overflows and an error light comes on.
Wash and clean the strainer at least once a week. Don't let it clog completely.

If flushing the filter does not produce the desired results, check the drain hose and drain for blockages.
The working blades of the sprayer can also become clogged and coated with plaque. Clean them periodically from fatty deposits and scale. Use a fine needle or toothpick to check if the water supply holes are clogged.

In case of malfunction, it is better to replace the Aquastop sensor.
Pay attention to the condition of the seals that retain water while washing dishes. Wash rubber parts with special products every six months. Avoid using popular cleaning products to prevent the rubber from losing its elasticity.

Due to the wear of the seal, water during washing flows through the dishwasher door onto the floor, from there it flows into the pan and the error light comes on.

In a Bosch dishwasher, error E27 or E15 requires calling an assistant who knows how to correct the situation.

Most problems that arise during the operation of dishwashers can be resolved by owners themselves.

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.

Marking on dishes

There is a wide variety of utensils in a modern kitchen. And you will see everything here: ceramic and Teflon frying pans, silicone molds of bizarre configurations, glass and metal, transparent and black. And, if everything is clear with a cast-iron frying pan or an enamel saucepan, familiar from childhood, then questions often arise with another one. Will this cap be useful for baking a pie or something else?

In addition to the traditional burner, today we cook food in the oven, microwave, and convection oven. And the burners have now become different. So the question arises: is it possible to use the same saucepan or cup everywhere? Which one can you pour boiling water into, and which one only takes cold water? What is useful for cooking, and what is only for heating?

You don't have to go far to find answers to these questions. This is precisely why cookware labels exist. In addition to the well-known fork with a glass, which means that a particular product belongs to a food container, there are many others. Have a table like this and, if necessary, just find the icon you need.

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.

What can cause error E15 to appear?

Error E15 means that the leak sensor in the system has tripped. Water appeared inside the equipment and got into a special tray.

Error E15 indicates a problem with the Aquastop system; water has leaked into the pan of the car.

This can happen in several cases:

failures in the leak detection system itself;
a large amount of debris or food debris has accumulated in the drain line;
violation of the tightness of the pipeline or seals;
breakdown of the water sprinkler or clogging of its holes;
Using an unsuitable, excessively foaming detergent.

The appearance of an error code E15 is always accompanied by a flashing “faucet” icon. This activates the floating sensor foam marker and activates the anti-leak system.

If error code E15 lights up on the screen, do not rush to call a technician. Take the instructions for your dishwasher and read them carefully.

The drainage pump automatically starts and pumps water to avoid short circuits and equipment breakdowns. It happens that, despite the error, the pump continues to work. In such cases, it is better to unplug the dishwasher so that the working parts do not burn.

Modern dishwashers can self-diagnose their systems.

On a Bosch machine

Error E15 in a Bosch dishwasher automatically turns on the system for pumping out the remaining water;
if the filter is clogged, then on Bosch models it is located at the bottom;
The Bosch machine is easy to disassemble, body panels are removed for diagnostics;
There are two spray heads that can be easily removed and replaced with new ones.

Spray nozzles are located at the top and bottom of the chamber. Press the screwdriver into the lock of each of the spray arms and remove them one by one.

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.

Correcting an incorrect drain connection

Failures in the operation of modern PMMs are not always due to poor quality or failure of individual components and assemblies. Often, an indication in the form of a faucet may appear on the panel due to improper installation of the drain line. In such situations, there is a direct connection between water intake and discharge. If the outlet is connected in violation of the rules, then the collected water will flow out of the chamber itself. In turn, the electronics perceives such a phenomenon as problems with filling, which issues a corresponding message.

Avoiding such troubles is quite simple. To do this, it will be enough to correctly connect the Bosch dishwasher to the sewer system. There are several ways to do this, and the easiest way is to install a corrugated drain hose at the edge of the kitchen sink. For this purpose, special holders made of plastic are used.

Similar devices are present in modern washing machines.

It is important to remember that this option is not always relevant in practice. If we are talking about floor-standing PMM models, then such a drain can be considered exclusively as a short-term measure. The key point is that the dishwasher will be located low, and the sink through which dirty water is drained will be higher. The result of this will be overload of the drain pump, which in itself significantly reduces its service life.

Most often, two alternative methods of draining water from the dishwasher are used:

through the kitchen sink siphon;
when connecting the hose directly to the sewer pipe through a special rubber cuff.

The first option can be safely called the most successful. With this installation, several problems are solved simultaneously. We are talking about eliminating unpleasant odors due to the water seal, preventing the reverse flow of water, as well as creating the necessary pressure in the system and protecting against leaks.

To implement the second method, you will need to install an outlet in the form of a tee. The most important point in this case is the height at which the hose connection to the system should be located. In accordance with the instructions, it is located at least 40 cm above the sewer pipe, that is, the hose itself should not simply be placed on the floor.

Checking the “Aquastop” function

If a Bosch brand dishwasher is equipped with a system to protect equipment from leaks, then there is a possibility that the appearance of the described icon on the panel is the result of its operation. When the Aquastop function is activated, the water supply automatically stops. It is worth noting that the appearance of an error code is not necessary, while the indicator flashes.

If these symptoms appear, it is recommended to check the protection system itself. As practice shows, sometimes the source of problems can be the usual sticking of the sensor located in the PMM pan. It is also worth paying attention to the housing and all hose connection points, checking them for leaks. If such steps do not help identify the cause of the equipment malfunction, then you should:

turn off the dishwasher by unplugging the power cord from the outlet;
tilt the machine several times in different directions - such manipulations can help the float take its normal (working) position;
completely drain the water in the pan;
wait until completely dry.

In addition to all of the above, an important point will be the condition of the hose itself, equipped with the automatic system in question. It is important to remember that we are talking about a hose enclosed in a protective casing and having a special device in the form of a valve. In the event of emergency situations, the latter shuts off the water supply to the dishwasher chamber. The key feature is that the system can be triggered even if the hose ruptures.

When mechanical protection is activated, it will have to be replaced with a new one.

Bosch dishwasher: faucet error is on - 4 possible causes, Bosch dishwasher faucet error how to fix.

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.

When to call a professional for repairs

If you are not confident in your technical skills and knowledge, do not attempt to fix the problem yourself. The AquaStop system and the associated E15 error can have more serious consequences. For example, to sensor wear or a working plateau.

When the leakage protection system is triggered, the drain pump is always turned on. Pump out any remaining water in the dishwasher to prevent further flooding of the room.

Such a leak requires a qualified inspection of the equipment, a professional analysis of all parts and knowledge of the nuances of your model.

If, after restarting, error E15 appears again, check the reset algorithm in the instructions supplied with the PMM.

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.

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.
