Neff dishwasher – error E15 - washer.tomathouse.com

Everyday worries associated with washing dirty dishes take up a lot of energy and free time. For this reason, many modern housewives prefer to entrust this work to a dishwasher. But even high-quality and expensive household appliances, if the requirements for their operation are violated, can malfunction. Modern machine models are equipped with a self-diagnosis system that protects against significant breakdowns by identifying problems at the initial stage of their occurrence. One example is error E15 in the Neff dishwasher, indicating that there are reasons why it worked Aqua Stop.

What does error code E15 mean?

We hasten to reassure you that the E15 code should not be considered a global problem. You can easily eliminate the cause yourself without calling a service specialist. But this will require a little work.

So, an error with a code such as E15 on a Neff dishwasher means that the sensor protecting against water leakage has tripped. Note that a similar code with a similar decoding is found on dishwashers of other brands. For example, such a problem on Siemens washing mashine has many common features with the Neff technique.

The protective sensor is located in the pan and looks like a float with a wire connected to a contact.As soon as the liquid enters the pan, the float device rises and closes the contact terminal, from which the alarm signal is transmitted directly to the control module. The latter immediately blocks the water supply to the Neff machine, stops the work process, and sends a signal to the display in the form of code E15.

For what reason can liquid seep into the pan? Perhaps one of the pipes has worn out, or liquid enters the pan from the washing compartment due to the fact that the sealing rubber located at the bottom has become leaky. Both are quite possible, but not in this case. The E15 error signal will most likely appear for another reason.

If it is not supported by other codes, you can confidently diagnose the formation of a blockage in the garbage filter. Water is not able to go down the drain, and is squeezed out through the seal into the pan.

How to fix the problem?

Let's figure out what needs to be done to correct the situation and normalize the flow of water, preventing it from getting into the pan. First of all, we check and clean the filter, because this is where the most powerful and unpleasant blockage can occur, stopping the normal operation of the Neff dishwasher. The algorithm of actions is as follows:

dishwashing equipment disconnects from all systems and extends to the center of the room to make it more convenient to work;
We recommend laying out a lot of rags at its right panel and preparing a bucket to wipe the floor;
tilt the dishwasher to the right so that the liquid completely flows out of the washing compartment;
if there is too much liquid, you can substitute a basin or other container that is more convenient;
Having removed the water, you must take all measures to ensure that the body inside the dishwasher is completely dry (install the equipment near the heating radiator, use another method);
Having opened the loading hatch of the Neff machine, remove the lower tray for dirty dishes and put it aside;
There is a garbage filter in the washing chamber, which should be unscrewed and cleaned thoroughly. We do the same with the mesh located near the filter;
We install all the elements in their places, connect the dishwasher and perform a test run. In most cases, error code E15 does not recur.

There are cases where blockages in the filter have a negative impact on the sealing elements. As a rule, due to excess pressure caused by a clogged dishwasher system, the modular ring in which the filter element itself is installed fails.

To get to such a ring in a Neff dishwasher, you will have to remove the right panel. It is more convenient to do this through the pallet, but not everyone wants to remove it for such a trivial issue.

The worn seal is clearly visible; it should simply be removed and replaced with a new analogue. To keep your conscience clear, we recommend checking the pipes. It is likely that a crack has formed in one of them, through which water is leaking. The problem is probably related to loose fastening clamps. If you have already removed the side wall, check all the elements of the Neff dishwasher that appear before your eyes.

Conclusion

Now you know why error E15 may appear on the screen dishwasher Neff. If your actions are unsuccessful, we recommend inviting an experienced specialist to help.
