Sump and Motor Assembly WPW10780877

Changed the sump pump

Double checked the model number , watched the video, ordered the parts . I got them in about three days , They looked exactly like the old ones. Proceeded with the disassembly just like the video explained and everything was going great.until I got to the installation part. The new unit would not fit in the sump. even though it looked exactly the same size as the old one. I worked with it every way I could, lubricating it and applying light pressure and finally beating the fire out of with a hammer and it just would not seat in the bottom of the sump. I removed it and reinstalled the old one and fit right in. So I removed all the parts out of the new unit and installed them in the old housing. From that point on the installation went well and now the dishwasher is as quiet as a mouse and so is my wife now. I did not have anything to measure the diameter of the unit accurately but eyeballing it with a rule it looked to be maybe a n 1/8" larger. So it appears to have been a tolerance problem. Not happy about that but I was able to get dishwasher going and the video was great help .

I watched the video of how to remove and install the part. Instructions were good and easy to understand. The hardest part was getting the part to fit in the opening, I sprayed the rubber seal with soap to make it slip into place. The only thing I would add you need to wear gloves if your dishwasher is stainless steel. I have several small cuts on my hands, I got gloves half way thru the process. I also replaced the drain hose. It is working great.

After struggling with the Sump / Motor Assembly for over an hour, I applied a generous coating of silicone lube to the rubber gasket, seated the Assembly and put in 2 of the retention clips. Then, with the aid of a 20 weight to hold the Assembly in its fully seated position, I was able to insert the 3rd retention clip. This method worked well but the company video does not show doing anything like this. Without the lube and weight installation is probably a two person job.
All the rest of the assembly went easy. The Dishwasher now works like a brand new one.

The Youtube videos do a great job of describing the repair, only problem is they skip over the steps required to remove the dishwasher from the cabinet. Turning off the water supply and disconnecting the line from the washer required a stubby wrench due to low clearance. Make sure you kill the breaker to the dishwasher (check the display lights to confirm), because you may have to undue all the wiring to pull the unit out. The power supply has a cover that you remove. Disconnect the wiring and unscrew the ring that holds the romex power line in place. Once the ring is unscrewed, you should be able to pull the romex power line from the back of the power supply box. That enables you to pull the unit out. Also watch for screws in the side of the dishwasher that hold the unit inside the cabinets. Mine had 2 just inside the door lip.

First I would like to say I was concerned about undertaking a dishwasher repair ,as I now am legally blind and I was concerned that my vision impairment might cause me a problem. My dishwasher pump motor was not running and from the humming sound I could tell it was cycling power off on the thermo switch overload. The pump can be removed by turning it counter clockwise,however it would not move and I could not rotate the motor manually, IT appeared that the impeller must be jammed,so I removed the complete ascribe..After I removed it the motor still could not be removed for replacement. I ordered the complete assembly from PartSelect.com an was supervised how fast it was delivered. The hardest part was getting the seal to go in place as it was new and a tight fit. The Partsselect.com video's ,on repair instructions were very helpful. I reinstalled the dishwasher and everything worked fine.Thanks for thefast delivery of my order.

Removed washer from the cabinet by unscrewing anchor screws at the top of washer. But first I removed both dish racks. Shut off power and water to washer. Unhooked water line to washer. Lowered front adjustable feet so I could easily pull washer free from the cabinet. Disconnected wiring from the wall box to allow room to allow for more working room. Drain hose was plenty long on my washer so didn't have to disconnect. Before laying on side, I disconnected the lower and upper spray units. Lower spinner is attached with a hand tightened screw in the middle of spayer. This is a left hand thred. So I had to turn it to the right to loosen. The upper spray unit is simply removed by uncliping the clips from the long flat tube that runs from the lower unit to the top. There is a set of clips in the back of the tub and a set on top. After the clips are free, turn the flat tube to your right to unlock from the bottom spinning unit. Remove and lay the washer on its side. Also before I did that I unhooked the springs at the bottow of the door so to free the door from springing back up after opening the door while on side. Good idea too to have some towels handy to absorb spilled water from the washer. I used one under the open door while on side to protect the door and floor. There are three wire disconnects under the washer that hooks to the motor, etc. There are three vinal wedges that secure the motor and punp into the bottom of the tub. Remove them, disconnect the outer pump from the motor (made it easier for me to remove the unit through the hole in the bottom of the tub. This is a little tricky. Disconnect by turning the small pump to the end of the motor to your left to unlock. The small pump is a little stubborn to losen, but will break loose with presure persistence. After removing, simply push the whole unit up through the bottom of the tub to remove. Now you are ready to reinstall everything in reverse order. It is a good idea to have someone to assist with installing the motor and punp in the tub. I securely pressed it into the hole and the second person press the vinal wedges back into the bottom of the tub to secure the unit. Putting it all back together from there was a snap.
A big plus is the quick delivery. Regular delivery 3 - 5 days will do. I ordered my parts one day and received them the next by Fedx. Didn't even pay the extra for next day delivery. Everything worked perfectly. Just like a new one again. Very happy with the helps posted and service and parts provided by PartSelect.

Rather than just replacing the motor and seal, I figured it would be just as easy to replace the sump and pump assembly also. It makes sense because the extra cost is minimal and I have a completely new unit now. The repair is quite simple. Just three clips holding the sump and a few electrical connectors and the unit comes right out.

Killed the power and shut off the water. Unhooked and unplugged power, hot water and drain connections to move washer to middle of floor for easy access to all sides. Taking out the the main pump/motor assembly (the "Assembly")required taking out the flat white hot water tube that feeds the upper and middle sprayers. So, I started by taking out the two trays. Then, took out the lower, middle and upper sprayers. Then, tipped the dishwasher onto its front and disconnected the hoses and several electrical connections from the Assembly. Also, unhooked the drain pump motor and impeller from the Assembly since these are not included with the new Assembly. Took out the three sliding retainers to release the Assembly from the bottom of the dishwasher. Took a little gentle coaxing to release the seal between the Assembly and the tub bottom. Took the Assembly apart and found that the problem was the shaft bearing (ball bearings) between the motor and the impeller had rusted and subsequently failed. Therefore, buying just a new motor would have not helped. Inserted the new Assembly into place from inside the tub. Because of the tight seal, the Assembly had to be carefully placed into the tub opening and the seal gently pushed into place by working all the way around in 1 inch intervals. Took about three trips around the seal of the Assembly to ensure a tight, even fit. Otherwise, working unevenly around the perimeter will bind the Assembly and you'll have to remove it and restart. Once in and seated evenly in its place, reconnected the hoses and electrical connections. Installed the drain pump motor and impeller onto the new Assembly. Tested the unit for proper operation and leaks. Found no problems. Then re-installed the water tube, sprayers and trays inside the machine. Helps to jot down steps taken to disassemble so you retrace steps to re-assemble.

This was a fairly easy repair. It took me a little over an hour to complete. First I flipped the circuit breaker for the dishwasher; then I removed the dishwasher from the cabinet and disconnected the supply, and return lines. I removed both racks from dishwasher, the lower washer arm, and the plastic conduit that supplies water to the upper rack. I then turned the unit onto it's side, and pulled the three or so cables that went to the motor, along with the three plastic wedges that held the motor in place. I then pushed the old motor through, into the interior of the dishwasher. This required me to disconnect some additional components to get it to fit through the opening, including the large silver capacitor. I then compared the old motor to the new one, and transferred some of the parts from the old motor to the new one that weren't included with the new one. I then pushed the new motor through the opening. This required a second person, who replaced the plastic wedges, while I pushed on the motor. The cables, supply lines, drain lines, and components that wouldn't fit through the opening were then replaced; the interior of the dishwasher was also reassembled.
