Customer Questions and Answers for Pump And Motor Assembly by Whirlpool

Mike, The motor is OK, it's the impeller that may be "shot" . Before you replace anything, check and make sure the dishwasher drains properly and completely, The water level in the tub, when started, and after a 3 to 5 minute wash cycle, should be within 1/4 inch of the heater element,at the least. If alls OK, then replace the motor pump assembly W10782773

Hello Mike, Turn off the power to the unit and verify the power is off. Remove the lower rack and remove the spray arm. Close the dishwasher door and remove the kick panel. Remove the drain pump from the side of the assembly and slide it aside. Unplug the harness from the pump and motor assembly. Remove the drain hose and pull the three clips out that hold the pump and motor assembly in place. Push up on the assembly and the assembly will "pop" out of the installed position. Open the door and carefully pick up the assembly and rotate it enough to get it out of the opening, remembering there are still two connections to remove. One is the turbidity sensor which removes by turning it about 1/4 turn and pull it straight out. The other is a ground wire that will require a 1/4 inch socket or nut driver to remove. Be sure this ground wire is reinstalled so no one gets electrocuted. Now you should be able to set the old assembly aside and begin the installation of the new one. The first thing you need to do when installing the new assembly is to connect the ground wire and reinstall the turbidity sensor. Be sure the gasket is correctly placed on the bottom of the sump. Set it back in with the groove lined up to the front. When you push the assembly down into the opening be sure to push the back down first. Reach back under the unit and re-install the rear two retainer clips first. Reach inside and push down slow and constantly until the assembly looks close to level in the floor of the tub. Quickly lay back down and install the front clip. This is where speed is important. If you take your time to get back in the floor, the pump will slowly raise back up and you will not be able to install the front clip. The remainder of the re-installation is the reverse of the removal process. Be sure to run the unit with water in it with the kick panel off to check for leaks.

Hi. Circulation Pump and Motor Assembly Part Number: W10782773. Remove the lower rack and the spray arm. Look at the side of the sump gasket.

Hi Peyton. Remove the power and the racks. Use a shop vac and towels. Remove the top sump screen and lay the parts as you rinse them clean under the sink.

The motor pump assy. part # W10782773. Thank You.

Hello LL. If the chopper was good and clean on the unit, then you will need to replace the circulation pump W10782773 in the unit.

Hello Larry, The first thing a dishwasher does when it's started is try to pump out. If it makes a grinding noise as soon as it's started, there is a foreign object in the pump. If you look at the parts explosion, it's part number 6 on the pump and motor page. It's referred to as a chopper blade and can be accessed from inside the unit without removing the assembly from the unit. Please check out the attachment. It's a service manual for a dishwasher with the same configuration pump and motor assembly. Look at page 21 of the service manual and it tells how to access the chopper blade. Clear this area and the problem will be solved. The only thing is if it was a piece of glass, this sometimes breaks the shaft that drives the blade W10083957V, so the blade may require replacement.

Hello Barbara, I believe you should check under the float switch and if nothing is under it holding it up so the machine thinks it's full, replace the water inlet valve.
