GU2400XTPS7 Whirlpool Dishwasher - Instructions

pull out the dishwasher
lay it on its side
use a 1/4" drive socket with extension and a universal joint to undo the the hidden bolt,
twist the motor 1/4 turn. this is the hard part you have to pull fairly hard and rock the motor around a little to get the o-ring to let the motor slide out.
lube up the new motor with jet dry or soap and insert back it, turn it back 1/4 turn, install the bolt and plug the motor control wires back in, then reinstall it back under the counter

Saved ~ $ 100.00. Easy job. I wished I didn't wait so long when it was making the noise for so long...Good luck..

If your not getting clean dishes this is an easy check to make that will likely turn out to be your problem. If not, you need to get this far anyway and it's an easy check to make. Remove the top and bottom rack. The bottom and top sprayer are connected together as an assembly by the water transfer pipe the goes up the back side of the dishwasher interior. This needs to be removed. There are two clips that hold the assembly in place at the middle rear of the washer and the top of the washer. Grasp the water assembly with your hand at the location of the clips, top one first and give a twist that rotates the piece out of the clip. Once the assembly is free from both clips hold the assembly at the lower rear where it starts up the back of the washer and move the whole thing to your right to turn the base clockwise. The whole thing will release from the bottom of the washer and come out as one big piece. Set it aside and you will see four torx head screws that were hidden under it. Remove these screws and the round screen assembly that they are holding to the bottom of the washer. Set that part aside as well. Now your looking at the well area where water collects to get into the pump. There will be a little standing water there, it's normal and not a problem. To the left side of the well an inch or two under water you will see one Torx head screw. It's one bit size smaller than the other screws. Remove it and pull up on the cover that it is holding in place. Now you are looking at the chopper assembly, it's a four bladed knife that rotates across the face of a screen. If you can rotate the knife blades and not have the shaft behind the screen move, it bad! Grasp it by the top of the screen and lift it slightly and pull it toward you to remove it. The shaft that turns the blades has worn away where it connects to the blades. It doesn't turn anymore so the screen is plugging and no water is able to get to your dishes. Order a new one and put it back in the same order you took it apart. It helps to have a little screw driver to lift the knife blade away from the screen when your putting in your new part. Load up the washer and give it a test run. YOU DID IT!!!

The repair was easy. Getting the unit to slide out from under the counter was more time consuming.
After water and power is disconnected, tip the unit over onto one side to gain access to bottom. Look for two white composite plastic posts (insulators) about 2" long each with a single wire inside. Remove the two wire connectors then unscrew the insulators from the old heating element using an adjustable wrench. Inside the box remove the two metal element supports and pull out the old element. Clean and dry the area in and around the openings where the new element will be re-inserted. Carefully place the new element into the holes with the included new rubber washers. Re-install the two metal element supports on the inside of box. On the bottom, re-install the two insulators to the ends of the element, do not to tighten too much to avoid over compressing the rubber washers which could cause premature cracking. Reconnect both wires and check continuity from the door mircro-switch (white-violet) lead to the (white-red) lead on Electronic Controller connector #1 (P6). The circuit thru the element should be good if the Multimeter reads 10-35 ohms. Put the unit securely back under the counter and run a test wash. Works fine now.
I do recommend, if don't know how to use a multimeter or are concerned about accessing the electronic control box; contact a professional.

I removed the dishwasher from under the counter. This took the bulk of the repair time along with disconnecting the water supply and electrical connection. I had enough slack in drain hoses that I could turn the dishwasher over to replace the motor. I was surprised that there was only one bolt that held the motor in place. I put the motor on, turned the dishwasher upright and slide it back unde the counter and began the long process ofreconnecting everything. I am sureit could have gone faster if I were younger and did not need glasses for close work. Start to finish took me four hours. This was the fourth time I have replaced motors in dishwashers of various makes.

First research then troubleshoot
Removed
1 Upper rack
2 Lower rack
3 Lower Wash Arm and Strainer Parts
4 Upper Wash and Rinse Parts
5 Accumulator assy.
6 Motor shield
7 Inlet protector (most difficult)
Noticed blade was broken off chopper assy.
Replaced chopper assy.
Runs and cleans like new.
Most difficult step was to remove Inlet protector
After removing two torx screws (#15) used small pry bar to lift inlet protector from position. Not easy to accomplish with hands alone. Inlet protector fits tightly into position.

When the top rack stopped cleaning, I tracked down the problem to the food shredder/chopping blade, and then to the impeller that drives the blade. The knob on the impeller had sheared/broken off. That meant removing the motor, and replacing the impeller. Four hours, a band-aid, and a trip to Home Depot later, here are my suggestions

1. Look for videos – this site is awesome, but they don’t have a video on this particular repair. I found 4 that got me close to knowing what I was doing.
2. Do all the “remove internal stuff” - you had to anyway to find the issue with the shredder/cutting blade
3. Take pictures as you move along, you’ll need them when you have to remember the placement of the water line, drainage hose, wired connections etc.
4. You need a 1/4 inch socket set. A 3/8 drive will NOT work (it won’t fit between the shroud and the base). Don’t start working on the repair, unless you have a 1/4 in socket with about a 6" extension
5. Someone at Kitchenaid should be shot for having the waterline connection facing the back of the unit. Use a short adjustable wrench
6. The order comes with a washer, but when you take the impeller off this model, you’ll see you don’t need it.
7. Placement is everything – there was zero clearance between the bottom of the unit and the floor. Placement of the water line, drain hose, and power line was critical – had to re-position the unit about 7 times to get it to “play nice”.
8. Hindsight – only needed to remove the wire harness for the motor (take pictures)
9. Hindsight – gloves are a great idea – sheet metal is unforgiving

Replaced the switch, that did not fix it, but a new circuit card did

Major appliance retailer sent out a repairman to diagnose the issue with the washer. They determined the control board needed to be replaced. They wanted twice the price for the part plus an additional two hundred dollars to return and install. Total time to remove and replace the part less than fifteen minutes. I purchhas same issue. Once again the repair people, (another $80.00 for the second service call), say the control board muased the part from Part Select and installed myself. Washer st be replaced. I will purchase another dishwasher.

no actual 'repair' was necessary, but, i was blown away at the speedy process of ordering and delivery of the part.

Simply made sure the cap was securely in place.

I watched the video identifying the part and the procedure to make sure I could handle this. The phone attendant was also very helpful in making sure I ordered the correct part,which arrived in one day (amazingly). Everything was clearly described in the instructions and if you have done electrical work this would be relatively easy. You will need a specific screw driver bit to open the control panel but everything else is straightforward, just follow the instructions. Works perfectly now (I needed a new control panel about a year ago and Kenmore charged me $229 but it was just over a year since then....) PartSelect is a great service!

I took out the old one and started in the lower left corner and threaded it all around the edge to make sure the placement and length was correct. Then I came back around with a plastic spatula to firmly seat the gasket into the groove. Worked perfectly and havent had any trouble since!

Disconnected power to dishwasher. Removed water supply hose from inlet water valve.
Removed lower and upper racks. Removed Lower spray arm. Removed tube from pump tp top spinner. Pulled dishwasher from under cabinet (remember to tip to get back out!). Placed dishwasher on its back. Removed electrical connectors from water valve, main motor and drain motor. Removed drain hose from drain pump. Removed pump/motor assy by pulling out wedges and pushing assembly into dishwasher. Removed pump/motor assy from inside dishwasher. Cleaned out pump. Installed new chopper. Re-install pump/motor assy. Re-install driain pump hose. Re-connect the pumps and water valve electric connectors. Slide dishwasher near cabinet for re-install. Re-connect drain hose to dishwasher. Re-install dishwasher under cabinet.Reconnect water supply. Removed top spinner from tube. Installed new spinner onto tube. Re-install tube onto main pump (below lower spray arm). Clean out and re-install lower spray arm. Remove middle spray arm from top rack. Clean out spray arm. Re-install spray arm with a new gasket (gasket may have not been needed). Re-installed lower and top racks. Re-connect power supply. Position all three spray arms pointing towards the door to confirm they were turning. Tested dishwasher - confirmed fill, wash, and drain properly. Also confirmed that all three spray arms were turning. Machine is washing, draining and running great since!

After pulling the dishwasher out from under the cabinet, I found it underneath near the back right side. I disconnected the old thermostat, unscrewed the clamp holding it into place, put the new thermostat in, screwed it back in and replaced the two plugs. Then I pushed the dishwasher back into place, and it initially didn't work until I found an online forum that was able to identify the reset command for my dishwasher (for the WDT710PAYM4, press any three buttons in a sequence of 1 2 3 1 2 3 1 2 3. After completing that all the lights lit up, and I shut the door leaving it for half an hour) Once the reset finished, the heated dry worked like it was suppose to.
