I'm not sure what you are calling a " fill switch'" unless you mean the float switch that 's there in case the water level get's too high. Follow the water line coming from your house hot water line ( it usually starts at a valve under the sink ) It goes to a solenoid operated valve under the tub of the dishwasher . Put your hand on it when you hear the buzzing . Is this where the noise is coming from? If yes - then either the valve is clogged up and no water is passing through or the valve is defective.

Hello again . Boy you've all ready spent a lot on this dishwasher . The blower relay - part #99001425 is $ 48.15 and the blower motor - part # XXXXX is $60.20 . Have you considered disconnecting these wires ( tape them up of course ) and just letting the dishes air dry ? Otherwise you're close to the price of a new dishwasher ( counting what you've all ready spent. Thanks for using justanswer.
All these quiet times are when the motor should be running to do the washing and pumping out. You say you've all ready replaced the motor / pump assbly and I don't see how you could have miswired it as it has a plug that only fits one way and it's not the door switch or it wouldn't fill so you're down to the timer itself - another expensive part. You could look at the timer where the wiring harness plug into it - pull the harness off and look into to it to see if any wires are burned,loose, etc. Does the timer at least advance on it's own without you manually advancing it ?
