My GE dishwasher is getting some severe chatter from the drain solenoid. Everything else works fine and it drains fine, it's just extremely loud while it drains. I have already replaced the solenoid kit to no avail. After some research it looks like it could be caused by whatever is supplying the power to the solenoid. There is no traditional control board on this basic model GE(ADW1100N10WW), but there is a timer(WD21X10350). I'm not sure if the timer could be the cause or if there is something else. Any assistance would be greatly appreciated.

Thanks,
Brian
