I replaced a broken power cord in my 15+yr old portable maytag dishwasher as it was much less than a brand new one. I also need to change the seal in the door but that will be another day. Anyway, after removing the four screws inside the door with the torque screw driver (t20, I think) , remove the two screws attaching the counter top to the unit and took that off. You get to them from under the top when the door is open. Then remove two screws from the back of the unit. You can now remove the two screws holding the casing in the front of the unit. I think that is all you need to remove the casing and counter top. You now will need to remove a shield from the back of the unit. You will now need to remove four screws holding the front panel that hides the power cord box and other wires. The power cord runs into a small box that you will need to use the small socket to remove the cover. Disconnect the wire nuts and ground wire from the unit. This will release the power cord from the wires of the unit. Using a pair of pliers, pinch the black thing that holds the power cord in place and pull it through the hole it is slid into. You will need to use some force to do this. It took longer to do this than it did to get to that point for me. You must do this again on the side of the unit where the power cord goes through and runs to the back of the unit. Pull the old power cord out of the unit through the holes in the front and side where the black things were holding it tightly. You have removed the old power cord and are ready to install a new cord. Remember to run the power cord through the compartment in the back that it is to be pulled from when you operatate the unit. This is also where the hose comes out from. After running the cord through the back of the unit, through the side hole and into the hole in the front you have to re-install the black things that hold the cord tight. Be sure the cord is not touching the motor. I attached the cord to other wires underneath using duck tape keeping it away from the motor. This will require the pliers again and a little force to get the black thing to slip through the holes and keep the cord tight. It seemed easier for me to put the black thing in before I attached the power cord to the unit matching the colors up with the wires from the unit. This would be a good time to make sure the wires are connected by plugging in the cord and listening for the unit to start. I put the controls on the dry setting to hear the dryer start. After verifying the unit was connected properly, I used the screws that I took out to attach the box over the wires, attach the front panel, attach the rear shield, attach the casing, and counter top, or any other parts you may have taken off. The dishwasher is one!!!

Latch handle broken

I saw an online video that showed taking the inside door panel off, removing the wiring from the latch and then replacing the latch. It looked simple and was simple. Luckily, I had a set of so-called "security" bits, which were required to get the door panel off. I had no trouble replacing the latch assembly except the wires to the two switches were very tight. It looked like the factory had squirted some adhesive into the connectors after assembly. I was able to get them off after a brief struggle and had no problems putting them back on the new switches. The latch assembly fit perfectly, which surprised me. My only disappointment was the latch assembly fit a lot of brands, indicating that there is nothing special about Maytag anymore. Too bad. They used to have good products that were unique for their quality. One last comment: Be sure to turn off the circuit breaker feeding the dishwasher or disconnecting its plug. This is the only safe way to work on it.

removed 8 screws, took the back of the door off, unplugged three wire just so I would have more room to work, could have gotten by with just removing two. Two screws held the old handle in place, replaced the old handle with new handle, reattached the wires, put the back of the door in place, replaced the screws and viola! working handle again! Guys, if I could do it, anybody could. Saved myself a $100.00 service call plus middle man cost for the part. All in all, a good move.

I simply removed old lower dishrack from dishwasher and discarded. Then I removed new lower dishrack from box and installed it into dishwasher, no tools necessary. How easy is that?! New lower dishrack is a perfect replacement and now our dishwasher is good to go. Thank you PartSelect for your fast service.

The original problem that brought me to Parts select was a broken wheel on the top tray. While searching for part #s I came across several descriptions of dishes not clean . The videos available on line here were very detailed. This encouraged me to go ahead and order the parts. They arrived soon and were accurate to my order. The video on replacing the seal and chopper walked me through the entire job very clearly. Going slow and carefully keeping track of al screws I replaced the chopper, impeller and the filter. The filter did have a tear in the screening which allowed dirty water back up into the dishwasher.

Part #PS2180046. Simply watched the video and followed instructions. Luckily I had the special screw bit needed to take the screws off the back door of the diswasher. Other than that it was very simple to do.

Dishwasher started leaking

Pulled the dishwasher out from the counter. Wiring and supply hose were long enough that I did not need to disconnect them. Suspected a leak in the injector hose but the evidence was circumstantial. That is mineral deposits collected around the area where the house connects to a small plastic box and then into the dishwasher. I replaced the hose in a few minutes and added a clamp on the box side where no clamp was called for. So far, no leaks.
