Thanks your question. please see this video

You just need a new door gasket and it is a cost effective repair if it still works okay for about $20.

Sorry to hear about your problem. If a butter dish does not clean I expect little or no flow from either wash arms.

Need to check the water level after the fill cycle. Open the door after 90 seconds after starting the machine. The water should be about two inches deep.

For testing a small amount of water can be added by hand into the bottom of the wash tub to confirm that the wash problem is no or low water. Add water and continue cycle to determine if that is the root cause.

No or low water check the overfill float switch in the front bottom of the machine. It can get stuck in the up position. The float in the at rest position(down) operates a switch that allows the fill solenoid to actuate.

Second culprit for low water is the stop valve at the sink connection. The valve has a rubber seat that has known to come lose and plug the fill line to the dishwasher. This is a common failure of the valve. If so repair valve (repair of the valve does not require removal of the valve it can be done in place).

If Stop valve is OK and dishwasher is not filling check the water fill valve in the dishwasher. Also a common failure. It is located behind the lower front cover and requires someone who is qualified to service. A replacement would be specific to your machine because of calibrated flow rates. Low water could be an indication that the screen in line at the valve is plugged.

If water level is OK than I would check for plugged water filter screen or pump inlet.

Good Luck

Does the whirlpool dishwasher gold series 857-5637 heat the water or does it rely on only the hot water that comes from your sink?

Yes, you almost certainly have a Whirlpool Gold Quiet Partner III Model #8575637
