Error E15 in a Siemens dishwasher

How to fix a Siemens dishwasher if error E15 appears on its display? Everything will depend on the nature of the breakdown that caused this error, but we can assure you in advance that in 85% of cases this code can be successfully removed with your own hands without the involvement of a specialist. So you have a good chance of fixing the machine yourself, especially after reading this article. We, in turn, will try to provide you with all kinds of informational assistance and support.

What does it mean?

If error E15 is displayed during the washing program, this can only mean one thing - the dishwasher has taken in too much water, and the sensor that monitors this has tripped. The fact is that a modern Siemens brand machine is equipped with a leakage protection system, which urgently turns off the machine if such a leak occurs. In this case, the dishwasher not only turns off, it also notifies the user about a malfunction and it does this using a code system, in this case issuing code E15.

On some models of Siemens dishwashers, any error code, including E15, is accompanied by an unpleasant, but loud and clear sound signal.

How to find the cause of the error?

It is clear that on a Siemens dishwasher, an error with this code, in most cases, appears due to a leak. But still, you should finally make sure of this, because it happens that the sensor or, even worse, the control module fails, and all the electrics, along with the electronics, begin to fail. Let's do the following.

• Let's unplug the dishwasher.
• Let's turn off the water.
• Let's disconnect the sewer and water supply lines.
• Let's take the dishwasher out of the niche in which it was installed.
• Place a cloth on the floor and tilt the dishwasher. If water flows from the pan onto the rag, then it really is a leak; if the pan is dry, you need to look for a problem in the electrics or even electronics.

If a leak occurs, there is a high chance of repairing the machine yourself, but if the electrics and electronics are faulty, it is better to contact a specialist. So, we figured out that the Siemens dishwasher really was leaking. So you need to find the place where this leak formed. It sounds simpler, but in reality this is the most difficult stage of repair, which in some cases takes a very long time, especially if the repair is done by a non-professional.

To quickly find the location of the leak, the dishwasher should be partially disassembled. We remove the lid and the back wall so that the gap between the washing hopper and the tray can be seen as best as possible. Next, we connect the machine to water, sewerage and an outlet, and then run a test wash.

Be careful! It is unsafe to start a partially disassembled dishwasher. Try not to touch conductive elements.

While the dishwasher is running, your task, while lying down, is to monitor the clearance between the tray and the washing hopper. As soon as water starts dripping into the pan, your task is to localize the location of the leak and remember it well. After this, you will need to turn off the machine again and, after removing the pan, accurately determine the location of the leak and the part that has become weak.

How to fix it?

Some users do the following when a small leak occurs.They simply drain the water from the pan and start the dishwasher again. If the leak is not severe, then this measure helps for 1 wash cycle. Then, in order to start the washer again, you have to drain the water again and so on ad infinitum, until a sensible thought comes to mind - to try to repair the machine.

From our point of view, this option cannot be called acceptable. In such a situation, you need to look for a leak and fix it either by replacing the part (which is best), or using improvised means like cold welding or sealant. If a leak has formed at the junction of the pipe with a plastic part, you can try to tighten the clamp more tightly, having previously lubricated the junction with sealant.

If you find damage to the body of the washing hopper, it is better to repair it by cold welding. Moreover, the damaged area should first be dried with a hairdryer, degreased, and only then covered with an even and not too thick layer of cold welding. If the circulation pump housing bursts, the part should be completely replaced. It is impossible to repair a burst housing using improvised means.

In some cases, a garbage filter can cause a leak. If it becomes very clogged, this will lead to excess pressure in the system, which in turn will either rupture the pipe or do something similar. Therefore timely replacing and cleaning the dishwasher filter – this is a vital procedure that can partially protect your “home assistant” from malfunctions. Don't neglect her.

So, we figured out the meaning of error E15 in a Siemens dishwasher and what to do if this error stopped the “home assistant” from working.We have identified a list of breakdowns that this code provokes, and figured out how to find and fix them. We wish you a successful renovation!
