Good morning What does code e02 on a bosch exxcel dishwasher

Good morning

What does code e02 on a bosch exxcel dishwasher mean & how do I fix it?

Thank you


Can you post the E-Nr number of the appliance please?

It may be faintly etched across the top of the door.



Customer: replied 6 years ago.

The no is SMS50E02GB/04

There is an ID No 108811 and then 00917

I hope that this makes sense

Thank you


E02 is listed in the service manual as;


Running without heating.


Possible cause is listed as, "Working relay of heating defective".


The cure is listed as, "Replace the power module".


Unfortunately it would appear that you have a fault on the main control board of the appliance.


The cure is to replace the main control board.

This is located on the right side of the appliance and requires the right side panel to be removed (as well as the top).


If your machine is under 2 years old, and you still have proof of purchase, contact Bosch as the appliance has a 2 year warranty.


If it's over 2 years old, sorry, you need to replace the power board to try and cure the problem.


Sorry it's not good news or an easy fix.


Hope this is of some help

Let me know how it goes or if you need more help
