The dishwasher runs great through any of the wash/rinse cycles. However it does not completely empty on any of the cycles and it leaves the water level, just above the screen filter. BUT...in any cycle, by advancing the the timer to the "Pump Out" area of the timer and letting it run it's course, it will pump out more water. Doing this 3 times will eventually empty all the water. It is like the timed pumping cycle is not long enough for the pump to do it's job. There are no obstructions in the punp line to the drain. The sink top has a drain vent. The drain line has it's proper loop on the right side of the dishwasher and the line runs correctly to the drain. (no garbage disposal) Could this be an inefficient pump problem? Perhaps a worn impeller or seals, where it is not pumping enough water volume in the time allowed in the selected cycle?
I see that the replacement pump kit for this unit is: AP4510944 and it is in stock. Will this solve my problem?
Answer John, Before you replace the pump assembly, try this, disconnect the drain hose from the "drain vent" and drain the dishwasher into a bucket. If all's OK, the tub should empty in 60 seconds or less. If so, you will need to remove the drain vent cap and lift the interior cap off the housing and clear any obstructions in the pipe. If it still does not drain properly, Then replace the pump. Thanks
The pump runs good and it seems to have no blockage anywhere but will not pump water from the dishwasher. It does run in drain cycle but won't pump hardly any water. Sometimes none! Could it be something other than blockage?
Answer Hello Dino,
The issue can be a separated pump impeller. You see, the pump motor shaft is stainless steel, but the impeller is plastic. It can be spinning freely on the end of the motor pulley, in which case it would be unable to move any water.
My drain pump has two outlets. What hose goes on the one threads?
Answer Hello Frank. Those are not threads, they are compression rings. The hose that attaches there is the drain hose. The tub to pump hose goes onto the other pump outlet 5304475805.
