If you follow the track from the triac/transistor down to the terminal connector block and see what it supplies, then you have your answer. As a rules it’s either the water point diverter motor on the heater box OR the dispenser release solenoid that blew it.
A quick bit of detective work sussing out which lead goes where will locate the ‘orrible truth. 🙁
Re: Bosch dishwasher PCB pic with blown transistors
Yes had a quick smell of the dispensor solenoid and metered across it Whilst door was off. No shorts or burning smell. Possibly need to drag it out and inspect divertor. 🙁
Looks like profit gone from job. 🙁

On further visit found a little dirty water in base and yellow stain under diverter motor. Not taking chance so replacing heater box and dispenser solenoid along with module.

Blimey! Well if you’re going to that much trouble be sure to change the circl. pump impellor kit too while you’re there! 😀
Re: Bosch dishwasher PCB pic with blown transistors
The bottom one is definitely the water point actuator . The dispenser actuator is the one to the left of that one .
The 3 on the right…from top to bottom = Drainage valve , regen valve , filler valve.
No idea what the top chip is that you’ve indicated as blown
Re: Bosch dishwasher PCB pic with blown transistors
Top chip is a transistor and the tracks go to the blown bottom transistor. Must have taken it out when it blew. Cheers for the info on what controls what Paul.
Will leave impeller til next time 😆
