Bosch SMV43L10GB46 Dishwasher E15 & E02 Errors After Power Board Repair—Component Advice

Hi members that is my first message for help.

I have Bosch Dishwasher model number SMV43L10GB/46, it started water leak error E15 each time few months back, I opened machine and reset the microswitch and dry the area and restarted it seems start working again for few weeks and then same E15 error message. However lately it started not heat up water during the wash cycle and gave error E02. I have changed following components so far:
1: Heat pump unit/heat sensor.
2: Water drain pump.
Send for power module for repair, they have changed couple relays and a capacitor but on test same E02 error kicked off. I am confident that fault lies on the power board.
If some one kindly point the components on board need change then I can source and change to address this annoying problem or some experience member can point out which I may missed. Your kind help with much appreciated.

AI: After the power board was repaired and reinstalled, did you notice any visible signs of damage on the board itself, such as burn marks, corrosion, or damaged tracks?
Not sure, nothing obvious
AI: When the repair shop worked on your power module, do you know exactly which relays and capacitor they replaced, and did they provide any feedback or test results about the board's condition after the repair?
Not heating relay, and small cap close the 100microF/400V capacitor. highlighted in power board image.

So money to be returned - how did this repair take place? "By eye" did anyone even check it was working? Probably not and just replaced components in the dark.

I've had a couple of LM III's that didn't heat up, changing relays, new flash didn't help - only replacing the board solved the problem.

Ps. E:02 is an internal controller error .

Such an E02 error as well as an E04 error I already fix with my eyes closed, provided, of course, that the heater or heaters are working....

Mother dear... So in the dark? Without measurements?

Yes, I agree that maybe the repairer did not even test the board but changed two relays. The second reply also highlighted it might not be the hardware problem associated with the board.
