Error E15 in a Bosch dishwasher: why it occurs and what to do - Setafi

When error E15 appears in a Bosch dishwasher, this indicates an automatic shutdown due to filling the pan with water. The appearance of liquid, in turn, can be associated with a variety of reasons from problems with the drain path to a sensor failure. The main cases and repair methods are described in this material.

Causes that you can eliminate yourself

Bosch dishwasher error E15 appears immediately after the start of the cycle. It can be identified by the appearance of a code on the display and the blinking of the tap icon. Another sign is the constant operation of the drain pump. Sometimes it starts as if by itself, even if the unit is turned off (the sound of murmuring water is heard). Moreover, the device itself does not respond to commands and stops working.

The easiest way is to unplug the machine for a few minutes. After that, it is turned on again and the wash is started, but in most cases this does not help. Then you need to figure out exactly why the Bosch dishwasher gives error E15. In some cases, self-repair is possible:

1. Leakage in the sewer pipe and other elements of the drain system. If water has got on the floor (including from the outside, for example, after spilling liquid from the basin), it is necessary to eliminate the leak and turn on the device again.
2. Clogged filters - food residues regularly get into them, so at some point they can no longer effectively remove the waste liquid. Since it does not go away, the device automatically turns on the aquastop protection system. It is necessary to turn off the device, turn off the water, disassemble and clean each filter.
3. Sometimes the Bosch dishwasher shows error E15 due to the fact that instead of a special product, the user poured into the Fairy tray for manual washing or other similar compositions. As a result, a lot of foam is formed, which also enters the pan. It is necessary to turn off the device and let the camera dry for several days. If after that the Bosch dishwasher gives error E15, then the problem is related to electronics, the repair of which will cost much more.
4. An error can also occur as a result of using a low-quality detergent. Or the user put too much powder, tablets in the tray. Then again a lot of foam is formed - the solution is similar.
5. If the display of the Bosch E15 dishwasher is on, this can also be explained by the flow of water from the sewer. For example, the pipe and siphon are clogged, and then the water flows back into the unit. This is extremely rare, but nevertheless not excluded. It is recommended to turn off the tap, turn off the machine and clean the siphon, as well as the connection to the sewer pipe. You should also position the drain hose at the level of the sink, making a zigzag in the form of a loop, and install a check valve.

In what cases do they turn to the master

If the described methods did not help, and error E15 is displayed again in Bosch dishwashers, the reason is more complicated. It can be associated with leaks inside the drain system, blockages and even corrosion of the unit chamber itself. In such situations, self-repair is difficult - it is recommended to contact a specialist.

Leakage in the drain system

The most common cause of the E15 error in a Siemens dishwasher, Bosch and other models are leaks in the drain system, represented by several elements:

• nozzles;
• hoses;
• pumps.

Most often, it is the drain that flows, although sometimes there is a problem with the water supply system. You can diagnose a malfunction by the constant noise from the operation of the drain pump. In addition, the device stops responding to commands. It is necessary to disassemble all the elements, inspect them and rinse. If necessary, change the seals, tighten the clamp, and also install new seals.

Clogged filters

When error E15 occurred in the dishwasher, it is recommended to inspect the filters that are located at the bottom. Remains of food periodically get into them, as a result of which they can no longer normally drain the waste liquid. It accumulates in the tank, the machine perceives this as a signal of overcrowding and turns off.

Drain hose leak

If the Bosch dishwasher gave error E15, and a faucet is drawn, this may be due to damage or not too tight connection of the drain hose. First, you can inspect it yourself - check for twists and creases. If the part is very old, it is easier to replace it with a new one.

Depressurization of the glass seal

If the Bosch PMM showed error E15, this can also be explained by the leakage of the seal, which ensures the tightness of the connection with the pan glass (the part is in the tank). This is observed only after long-term operation, for example, for 4-5 years or more. You will need to replace the seal and check the operation of the device.

Wash chamber leak

Bosch rarely issues an E15 error due to a leak in the washing chamber itself. It is made of metal, which over time can begin to break down due to corrosion. That is why there are small holes that leak. You can restore integrity with a special sealant, but this is a temporary solution. If the unit is too old, you should start considering buying a new machine.

Door seal damage

When the dishwasher showed error E15, it is worth inspecting the seal adjacent to the door around the perimeter. As a result, water begins to flow through the door to the floor (during operation), and then into the tray itself. It is filled with liquid, the aquastop protective system is activated, and the device automatically turns off. In such cases, the seal must be replaced.

Cracks in the salt tray

If the Bosch dishwasher issued error E 15, this may also indicate cracks in the special salt tray or damage to the heat exchanger canister. This phenomenon is extremely rare, mainly due to improper storage conditions (for example, if the unit has been standing in an unheated room for a long time, in a cold warehouse).

Aquastop sensor stuck

Finally, the appearance of the E15 Bosch dishwasher can also be explained by a breakdown of the sensor, which determines the need to turn on the aquastop system. If no leakage is actually observed (i.e. the surface of the pan is completely dry), this indicates a breakdown of this part. It cannot be repaired - you will need to install a new sensor.

Thus, the E15 code clearly indicates problems with the drain system, i.e. the appearance of water in the pan, which does not go away and gradually accumulates. Because of this, the machine will not be able to work, because the automatic flood protection system will work. If it is not possible to eliminate the violation on your own, it is recommended not to take risks and contact an experienced specialist.
