Does the Siemens dishwasher have an E15 error? This means that the self-diagnosis system reacted to the breakdown that occurred – namely, a leak.

Causes of errors

Causes of errors Е15 dishwashers Siemens

The E15 error code on display indicates the activation of the Aquastop protection. In this case, the technique is turned off and can emit a sound signal. The protection system is triggered when water overflows into the tank or water leaks. You can hear the drain pump running continuously to pump out water, but the control panel will not respond to pressing.
With this error, you need to check:

  • connections of pipes and hoses, as well as their integrity;
  • correct connection to the water supply system;
  • filter and the entire drainage system for clogging;
  • “Aquastop” sensor for serviceability;
  • water level sensor.

An incorrectly selected detergent could also be the cause of the error. Excessive foam during washing will cause leaks and errors.

How to fix this error

First of all, eliminate the system crash by rebooting the machine and clearing the error. To do this, disconnect the equipment from the network for 10-15 minutes, then reconnect it. If the code is still on the screen, then check all the dishwasher components.

You can find out if there was a leak like this:

  1. Close the water inlet valve.
  2. Disconnect water supply and drain.
  3. Remove the dishwasher from the cabinet (if it is a built-in model).
  4. Place a rag and tilt the dishwasher forward. If water is poured out of the pan, then there is a leak. If no water is found on the floor, then there is a problem with the control module’s contacts. In this case, it is better to contact the master.

If the problem is a leak, locate the fault as soon as possible. The easiest way is to do this, carefully observe the components while the dishwasher is running. To do this, remove the top and back panels, connect the dishwasher to water and electricity, and do a test run. Now it remains to observe where the water starts to drip from. Found a defective part? Turn off the equipment again and start repairing.

How to fix the situation if the dishwasher hopper is leaking? You can try to seal the crack with plastic or metal welding (if the container is made of metal).

If the cause is the loose fastenings of the hoses, then tighten the clamps more tightly. When the circulation block leaks, the part is often completely changed.

Dishwasher filter

Siemens dishwasher filter clogged

Timely filter cleaning is the prevention of leakage. When the filter becomes heavily clogged, overpressure builds up in the pipes, so they break. Cleaning should be done at least twice a month.

How to do it:

  1. open the hopper door;
  2. pull out the lower basket;
  3. unscrew the filter in the pan;
  4. rinse with water pressure.

Clogged drain pipe

Clogged sewer pipes are one of the causes of malfunctioning Siemens dishwashers. The E15 error code informs users of this issue. Over time, filters and pipes can become clogged with food particles and other objects that should not enter the plumbing system.
Remove and clean all food traps and filters. Use a wire to clean hoses and pipes.

Inspect the belt (older models)

Some older dishwashers may have a pump drive belt. If the belt is cut or worn over time, the pump that drains the dishwasher’s water may not work properly. Inspect the part for wear and stretch marks. Replace part if necessary.

Check float (safety system)

The dishwasher float switch can get stuck or stick. This leads to the fact that water remains inside the appliance between the washing processes. Depending on the dishwasher model, the float can be small in size, installed in a corner, or an X-shaped device located directly at the bottom of the dishwasher. A damaged float requires replacement or repair.

Water level sensor

Reasons for failure of the part:

  • wear and tear;
  • oxidation of the sensor connection;

Choosing a new water level sensor is a very responsible process since each Siemens dishwasher model’s device can be different.

If you take proper care of the dishwasher, then blockages and leaks will not be terrible, and the error code E15 of the Siemens dishwasher will never bother you.
