Can confirm, tried to replace
V7 and C6 (22nF, yes) both correct even from diffrent version PCB (smaller vacuum) parts ARE in fact the same. Still didn't work somehow. Ordered a brand new board from Bosch and tossed the doomed one, will install and test. The only thing that was different was C6 wasn't 0805 but think it was 1206 or 1806 don't know about tolerances (caliper measurement 3mm~ in lenght). Yes I just took the hot air gun at the new board and took it off to verify. No warranty anyways I am the warranty.. Will update on what was the issue, I hope the coils are still fine.
Edit:
It's so wierd I can't find the problem I measured all parts.
Rotary wiper switch works, mains switch works all components none is shorted. But I do see changes in the design. They removed the 24vdc speaker control and sense, and removed the potentiometer just jumped and changed some resistor value. Will try this on the old board, want to know what the issue is. The new board works, and behaves different, still yet unable to find it. Maybe dead zener diode? I can't test it.
I found out it switches on the manual cleaning function (that the Triac is used for) when PIC detects R plane shorted by pull down resistors (560k Ohms 5%) to PIC pic16c621a-041/p pin 9 and 10. Dead PIC maybe??
Edit2:
I fixed the old board but had to modify it, remove components and replace values, never would have guessed this if Bosch never sent me the updated PCB.
Here are the changes I made to repair the old board.
