*The model number on the post description is wrong, I have a SHX46L15UC/50

Hello, my Bosch dishwasher stopped powering up when I hit the main power switch (at least the red segment display is not showing anything). I cracked it open and confirmed I have power from the main at the harness so proceeded to the power switch (part 00424410) diagnostic. Per the attached schematic troubleshooting (see attached image) I tested resistance across the pins as instructed in "No Power" Step 3. A gave me 0 ohms, however B and C did not so I assumed the part was faulty and ordered a new one which arrived yesterday.

The new part showed the same results upon resistance testing, and did not fix the issue when replaced, so now I am at a loss on what to try next (the schematic has no further solutions after the resistance test for the main switch).

If anyone can offer suggestions for next steps to diagnose my issue or has a hunch for what the problem may be, I would appreciate it! Thank you.


Not sure if my image attach worked, but you can view here:

After swapping the control board in my unit, all is fixed. Unfortunate that I had to pay $200+ to fix it, but better than $400+ to have a repair technician do it.

Quick tip for anyone facing a similar issue - There is a fantastic YouTube video for fixing some of the common issues with control boards by replacing a burned out relay. My control board had a burn on a relay solder just as the issue in this video has, however since mine did not power on at all it would unlikely fix my issue. But maybe it will help someone else in trouble: https://youtu.be/Jb8gAnMb2zQ
