Customer Questions and Answers for Pump And Motor Assembly (Drain) by Whirlpool

Lihua, the weight absorber should mount through the center of the assembly. It is recommended to utilize the parts that are designed to be on your appliance.

Rhonda, You might have some broken glass in the impeller area restricting motor movement. You can watch the video for part # ap3115180 to see how to access this area for blockage.

Sue, turn the power off to the DW and get access to the control board. With a multimeter, check resistance on the motor pins P5 to P9, you should read 3-7 ohms. if you don't get that resistance reading, replace the motor. If the motor checks out ok, I would replace the control. motor part number is WPW10780877, control is WPW10084141

Bigal, You will want to test p5-2 and p5-1 connectors on the control board to make sure the control is supplying voltage when it should be washing for 120 vac. Also, check connectors p10-1 to p7-6 for 120 vac to the diverter valve. I have also found the connector to the wash pump backed out on some units so a quick visual inspection might be worth your while. If you're not getting your voltages then the control would need replaced.

Peter, The pump and motor assembly W10428168 will come with the gasket and does not need any other parts for it. You will want to check to see if there is anything caught down in the pump assembly.

Nate, At this point, no you don't need a new pump " I can see water coming out of the dishwasher, so it's pumping out ". The water inlet valve controls the water entering the tub/machine. Try this, Start the machine on a regular wash cycle, allow the dishwasher to fill and start to wash(3 to 5 minutes) then unlatch the door, and remove the lower rack. Check the water level in the bottom of the tub. it should be approx.1/4" near the bottom of the heater element, if it's not at least that high/deep there's not enough water to properly wash dishes and operate the machine properly. If the water level is in range then check the water temperature. It should be a minimum of 120 dgrs.F. in the bottom of the tub on the first fill of the cycle.

Arbin, There is a check valve 675238 on the pump assembly that can get clogged or restricted, there's the possibility that the drain hose, the air gap or disposal could be clogged and not allowing the dishwasher to drain. There is also the possibility that the rain impeller inside the pump housing is broken or cracked, or the vanes have deteriorated and isn't moving the water when the motor reverses to drain the dishwasher 675806 But there are no drain valves or solenoids to stick or fail on this style/type dishwasher.

Hello Bill, It is recommended to pull the drain pump first to check for debris since this would save you the shipping on the part. You should order the W10428168 pump and motor assembly since this would guarantee there are no leaks from the assembly of the pieces which can be very hard to get installed properly. There is no restocking fee..

Debra, You will want to check the drain pump to make sure that there is 120 vac getting to it. If there is 120 vac to the pump but not pumping then make sure that there is no issue with clogging in the drain and if it checks ok then the issue will be the drain pump. If there is not 120 vac to the pump then the issue will be with the control board.

Eric, It is possible that the pump bearings are starting to fail. The reason that the unit would make a whine and then it taper off would be that as the bearings start heating up they move more freely.
