Bosch Dishwasher SHV43A03GB/42 FD8212470164 drain pump keeps running as though the float switch has been activated (no water) in base, also it keeps running even when you open the door and cannot cancel the program have checked door lock micro switch that’s ok. I also checked the float switch micro switch that was ok, pump keeps running even when both of these were disconnected.
Any suggestion please

Blown Triac on pcb for sure! If your lucky is just the one for the dispenser actuator otherwise it will be the water point motor on the heater.
Going to be close call for BER :rolls:

Thanks for the reply Pinky.
Not quite sure of your reply, do you mean it’s the PCB and could be something else that has caused it?
What is “the water point motor on the heater “?Bernie

Pinky refers to the water point diverter within the heater box has likely failed and blown a triac on the main PCB. Simple check is to remove and inspect PCB for surface damage, if there is, check carefully the adjacent plug-in connector and that will lead you to the guilty component……
