Siemens Dishwasher Error Code E15

The first thing that you need to do to fix error code E15 is to reset your Siemens dishwasher, as the error might have been caused due to a glitch in the dishwasher system.

If your dishwasher is under warranty, the easiest solution would be to contact Siemens support and ask for advice. Unfortunately, opening your dishwasher will void its warranty in most cases, so leave it as a last option.

If this doesn’t work, then follow the below steps to troubleshoot it:

  1. Turn off the machine and disconnect it from the mains.
  2. Pull the machine out, to let the water run out easily.
  3. Check the tray under the dishwasher. Make sure it is dry.
  4. Dissemble the lid and the back panel of the machine. This will lead you to the tray and the detergent section.
  5. Now run a test cycle, but be very careful as the machine is not properly assembled.
  6. Now analyze where the leakage is taking place and repair/replace the malfunctioning part.
  7. Also, check the water level sensor (with a multimeter) and its contacts. If it is burnt-out, replace it.

If you still have issues with your Siemens dishwasher, contact Siemens customer support.
