Went to look at this dishwasher, constantly pumping on selection.checked flood switch but not this. Checked PCB and found triac blown on board. this appears to switch dispenser actuator. looks like it is a silicone device and not a solenoid. No signs of damage or burning. meter reading across terminals was 2.1k ohms Any ideas on this please . I don’t want to try another board if this actuator is causing damage.
