motor noise over a six month period suddenly stop running.
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.

Dishes on the top rack weren't getting clean -- Motor was weak
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.

Dishwasher is about 3 years old, motor started makeing load noises.
Cut power and turn off water. Pulled the dishwasher out of the cabinet. Removed internal spray unit. Lay a plastic bag on bottom of tub in case a screw falls from upper spray assembly while removing. Disconnected and drained all hoses. Put down plastic lined tarp on floor. Lay dishwaser on its side onto tarp. Removed hose from recirculation pump, removed water sensor and recirculation pump from housing and detach electric connection. Removed 3 plastic push clips and removed entire motor-pump unit from tub. Position new motor-pump unit into tub. Replace 2 push clips into position, then used a flat screwdriver to put some tension and position plastic pump assembly so I could insert 3rd push clip into position. Replaced all components & reconnect hoses. Turn on water & power. A relatively simple repair. Too bad the original motor-pump only lasted 3 years. Not built like the used to. Thank goodness for Part Select.com Great schematics and descriptions. Excellent website, service, delivery and excellent Part! Thank You!

pump mmotor would not run
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.

Motor was making a loud noise for several months, then quit
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.

Motor starting making a terrible racket after installation 15 months earlier
Be sure to shut off power at circuit breaker and disconnect drain and water supply. Remove the dishwasher from the cabinet, lower it on its side. Remove three electrical connections from motor to various sensors. Remove three plastic wedges that secure the motor gasket to make a tight seal. The motor pops into the body of the dishwasher for removal. The replacement motor goes in just as you took it out. It took two people to set the motor right to ensure the good seal on the gasket for re-installation. Then turn it back upright and secure it in place. Couple suggestions, be sure to have ample towels around for leakage from water and drain lines. Be sure to cover the bottom of the dishwasher during disassembly and reassembly of the wash manifold. I dropped a screw in there and it took me some time to fish it out.
All in all, it went well. Don't pay a plumber for this job. I'm a clod and if I did it, you can.

The dishwasher is has been in service only 18 months and the seal between the motor and pump leaked, destroying the front motor bearing.
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.

Pump motor seals leaks and causes bearing failure
The whirlpool sump is pretty easy to service. Remove the lower cover on the front of the dishwasher, remove drain hose at the front, rotate the drain pump motor and remove it from the sump, there are 3 wedge type tabs that hold the sump to the tub, rotate and remove them then push the sump up into the dishwasher and remove the motor electrical connector and the optical sensor. Reverse process to install. This dishwasher is just over 2 years old and this is the second replacement pump, the first was covered under the 1 year warranty. Maybe this one has a better seal??? time will tell.
