GU2400XTPS3 Whirlpool Dishwasher - Instructions

Several hours to diagnose problem: Removed all the plastic water distribution tubes to top rack and found no blockages. removed lower water jets, drain screens using star driver on 6 screws. still could find now blockages. decided problem had to be in pump mounted below unit so completely disconnected unit and removed from under counter. Upon removing lower plate below door I discovered a plastic pouch containing an excellent trouble shooting guide with complete dis-assembly instructions and parts breakout diagrams with P/N listings! First thing I discovered from this was that the chopper assembly was hiding under a plastic cover just under the filter screen I had already removed. The trick was to press down on the right side of the plate to get it to pop up and reveal the chopper. The whole chopper assembly slides out without tools. I found the strainer plate behind the chopper blade totally plugged as the blade had broken off the plastic drive shaft because the retaining knob on the end of the shaft had broken off. I was able to drill and tap the shaft and install a SS machine screw with washer to reassemble the chopper blade on the shaft. Not expecting this "Joe Maggee" repair to last more than a few cycles I went online with the P/N and googled PartSelect. Placed the order and chose std delivery over 2day or next day since I expected the repair to last for the week. I put everything back together and the first load came out perfect! This was Sunday afternoon. Tuesday the part arrived at my doorstep! 15 minutes and the new part was in. My "Joe Maggee" repair is now in the junk drawer awaiting the next pistachio shell that gets run through the washer.

To empty the water in the dishwater basin, I pushed the cancel button and closed the door. I then turned the electrical breaker to the off position that supplies electricity to the dishwasher. I confirmed the power was off by attempting to start the dishwaser. I removed the metal plate between the dishwater door and the floor by removing the two screws. I removed the two screws that connect the top of the dishwasher to the underside of the countertop. I shut the water valve that supplies hot water to the dishwasher (mine was located under the sink). I disconnected the drain hose (plastic) by using pliers to loosen the clamp the holds the hose on the outlet of the drain pump (drain pump is much smaller than the pump that needed replacement). A towell is handy to soak up the water that comes out the hoses. I loosened the nut on the water supply hose (this was difficult because of lack of room)using a wrench and pliers. I opened the door on the metal box that houses the wire nuts for the electrical connection to dishwater, and I removed the wire nuts and the screw for the ground wire. Once the white, black, and gound wires were disconnected, I could pull the dishwater out. I also had to pull the drain hose out from the clips on the side of the washer to pull the dishwasher out into the middle of the kitchen floor. I flipped the dishwasher on its back. I removed the single bolt that held the broken pump motor to the dishwasher, and then the motor twisted counterclockwise and I pulled it out. The pump shaft would not turn freely with my pliers, so I knew the motor was broken. I removed the pump end (impeller) from the dishwasher by tapping it with my screwdriver. The impeller end came out along with a metal screen. The metal screen was 50% plugged, so I cleaned it and put it back in place. I wet the gasket on the new pump motor and slid it back in place while rotating clockwise and locking it in place with the tabs. I replaced the bolt that holds the motor in place and reversed the repair procedure to re-install the dishwasher. Be sure to run the dishwasher and look for any leaks. The last step is to replace the metal plate between the floor and door. While I had the dishwasher pulled out, I discovered another problem with the pulleys and strings that prevent the heavy door from flopping down, but I won't include this repair. The pump and motor must have been failing for some time because the dishwasher is much quieter now and the dishwasher is much faster. I am sure the plugged screen didn't help either.

This site is wonderful..., thank you. Especially thanks to Nanette's detailed experience. The thing that gave me the most problem (and apparently Nanette, as well) was removing the lower round cover of the chopper assembly. Finally, some one on the internet identified the trick...put needle nose pliers in the screw-hole and pull-away. It came right out. Wish I could acknowledge the source but now can't find it.
Actually, the check valve was good, but I replaced it anyway. It was 10 times the trouble to replace than the drain pump. Wish I had started with the drain pump. By removing the drain hose, I stuck my finger in the hole and discovered the problem: the impeller was off of the pump and lying in the bottom of the drain. It was a simple thing to replace the pump. Press down on the locking mechanism and turn it to the left. When it was off, I could see that the check valve was in place and not a problem. (Of course by that time, I had already replaced it.) Good luck.

I shut off the power to the dishwasher, then I removed the front panel under the door. On the right side just behind the electrical box there are two wires going up to the hi-limit thermostat, (you may need a small mirror to see it), remove one screw that is holding the thermostat bracket, unplug the wires from the old thermostat and install new one. Screw bracket and thermostat back to the underside of the dishwasher, reinstall the front panel, turn on the power, done.

I couldn't get dealer to order part, so went on line to see what was available. Found model and picture of part needed and ordered. It came in 3 days. Took part out of box and compared to part the needed replacing. It was a match. Removed old basket and replaced with new one. It works great and siverware stays in basket until put away.

I released the heater element from the clips on the bottom of the waaher tub. I pulled the unit out from the wall and disconnected power. There are two slip on wire terminals on each end of the heater element accessible from the back that need to be removed. One of them was badly rusted from leaking water, which had caused the short, and had to be replaced. These terminals and the crimping tool to install them are available at any home center. I removed and discarded the old plastic nuts since one of them was damaged by arching from the short circuit. Moving around to the front of the dishwasher, I removed the old heater and installed the new one. I had ordered new rubber washers, but the new heater came with them already installed. Since one of the old ones failed and caused the leak, they are a good thing to keep around as spares anyway. I installed the new nuts and tightened them to enough to ensure that the washers made a good seal. I reconnected the wire terminals to the heater, reconnected power and moved the unit back into place. The circuit opening when the heater failed caused a "call for service" error and the controller would not allow the unit to run. You will know you have this by the "CLEAN" LED flashing seven times. Clear the diagnostics by pressing the buttons for "HEATED DRY", "NORMAL", "HEATED DRY", "NORMAL" and after the controller resets, the dishwaher is ready to run. It's worked like new ever since.

Started as dishes not getting clean and I observed that the top arm was not spinning and there was very low water pressure coming out of the jets. After making sure the water level was up to the bottom of the heating element and making sure the jets were not clogged I checked the filter and chopper. It was a little tough to get the cover off of the chopper but once I did I could see that the chopper scraper was broken off and the shaft was broken. The screen was all clogged up with stuff. Ordered a new assembly and put it in making sure to compress the spring and make sure the gears lined up. Now it is running great.
I think the Kitchenaid is the same as the Whirlpools.

First: Turn power to the Dish washer OFF, then remove the two panels at the bottom of the dishwasher.
Two: remove the Door face panel for easier access to the inlet-Valve.
Three: remove screw that holds Inlet-valve bracket.
Four: slide Inlet valve bracket left and back to get out of slots.
Five: Holding the Inlet-valve forward loosen and remove water line (copper tube nut / pressure fitting).
Six: Remove two wire clips
Seven: Remove platics hose (Spring Clamp)
Replace Inlet-Valve and reverse process///

Turned off water and disconnected line, then disconnected drain, turned off power and slid dishwasher out and turned turned upside down and removed hold down bolt ( it is a 3/8 head bolt) removed wire from motor and twisted motor assembly approximately 1/4 turn counter clock wise and removed old motor and seal assembly reinstalled new motor with new seal and rewired. Turned washer back upright and removed filter assembly and lower jet arm, removed cover for food disposal and reinstalled disposal blade back on pump drive reinstalled cover and filter assembly and jet arm. Slid unit back in place and anchored down to cabinet and turned water and power back on ran washer through a short cycle to clean any soap build up that was left inside and that was it, it all works just like new.

Turned off power, turned off water supply and diconnected, slid out dishwasher. Removed the spray wand and tilted dishwasher to access the two nuts and disconnet the wires. Removed the two nuts using a socket. Removed the old heating element and replaced with the new one secured with new nuts ( the old ones were fine but since I bought two new ones why not). Pluged the wires back up slid the dishwasher back in hooked up the water reinstalled the spray wand cut on the water and power. Good as new.

Replaced electronic control panel first which had an obvious defect (burned terminal). Still no power. Replaced fuse and works fine now. Took lots of reading to find out the dishwasher had a replacable fuse. Even the appliance store didn't know.

Via your web-site I was able to download the step-by-step screen-shot pictures. I was really surprised on how easy the detailed photo screen shots made the repair really easy! Thanks for making this repair a piece of cake. If I should ever need additional parts for any of my home appliances I will certainly order my parts through PartSelect.

Got Maintenance Flyer out an read about problem
Removed access plate
Disconnectd water and drain
Removed anchor screws
Pulled unit out and disconnedted from Electric

Ordered and received Part
Changed out Thermisitor
Checked wiring to Heater and replaced connections
Hooked electric up
Ran Diognostics per Maintenance flyer and cleared fault
Hooked back up and ran like a champ

The reason it took so long is because I put the old thermisitor back in and tryed to run the diognostics just to make sure that was the problem

We recently installed all new stainless steel appliances, and were considering replacing the dishwasher as well (4 yr. old Kenmore, in good condition, energy star compliant, etc.). We decided to try to find a stainless front panel instead, and Kenmore said for that model they only came in black and white. But after calling Parts Select, they cross indexed our Kenmore model with a Whirlpool model that did come in stainless, and we simply ordered that front panel. The panel fit perfectly, only requiring the removal of 10 screws, and taking the insulation foam from the old panel and installing it in the new, then replacing the screws. Very simple, and economical, fix for our problem. Thanks Parts Select!

First I had to remove the upper dish rack from the dishwasher. This was the most difficult part of the entire fix. I found the screw which holds the spray arm in place, Removed it and took off the old spray arm. Then I replaced the seal and put the entire thing back together, put the screw back in and replaced the rack. Then I ran a load of dishes and discovered the machine works just fine now.
