Kenmore Ultra Wash III, part #665.1677991, serial # FD4435725 buzzing and not cycling.

Hello,

Part#
665.1677991

Serial#
FD4435725

As the title states, my dishwasher is buzzing and not cycling. Here is a video of the behavior which I hope helps.



I also have another quick question. Is it possible to manually drain the machine without having to remove the garbage disposal hose from the check valve? I can't get it to drain, and I have tested the check valve (which drains all over my floor), and I disconnected the drain hose from the dishwasher to the garbage disposal and blew air through it and rinsed it out with water so it is not clogged.

Thank you,

Chris

I was not able to view the video that you posted but I did listen to the audio portion. That buzzing sound could be caused by the motor relay. The first image below show a wiring diagram for that dishwasher with the circuit through that relay traced in blue. The third image shows the location of that relay. The second image shows the strip circuits for the wash and drain functions in the dishwasher. The same motor is used for the wash and drain functions. The motor turns one way for wash and the opposite direction for drain. Since the motor is not running, that is why it will not drain. You can probably gravity drain that tub by removing that hose on the check valve assembly. Use a shallow pan to catch the water. If that check valve assembly is clogged, then you can remove that component to drain the tub. Be sure that you

shut off the house circuit breaker

for the dishwasher before accessing internal components.

There is a chance that the relay is bad. You may be able to fix this problem by replacing that component. Here is a link for the parts list diagram on that dishwasher:

Kenmore UltraWash III Dishwasher Model 665.1677991 Parts

. That relay is Key 24 on the Tub Assembly page of that diagram. A photograph of that part is shown in the 4th image below. That part costs around $30.

If that relay is not preventing the motor from running and the motor is getting proper voltage through that circuit, then you probably have a bad pump motor. Reply with additional details if you need help fixing that type of failure.

If you get to the point where you need to have a service technician diagnose and repair this failure, you can schedule service through this link:
