GU1200XTLS3 Whirlpool Dishwasher - Instructions

First I checked the power supply and noticed the breaker was not tripped. Confirmed the unit was getting power. I then downloaded a parts breakdown from the Kitchen Aid website and noticed there was a fuse mounted in the control section. Using my digital multimeter I confirmed there was no continuity through the fuse. I then ordered the part, installed it and washed a load of dishes:-)

Switched circuit breaker off.
Removed kick panel.
Removed the dishwasher from counter.
Disconnected drain hose from the pee trap.
Disconnected drain hose from pump.
Installed new drain hose.
Reinstalled dishwasher in counter.
Connected hose at the pee trap.
Turned power back on. test for leaks by running a cycle.
Reinstalled kick panel.

Took racks out, loosen screw on top and back then twist feed tube to right and whole assembly can be removed. Now you should be able to see some torx screws; remove those and then remove the piece they were holding down, from there you'll see another screw, remove it and the piece and so on until there are no more screws. Now there is the food chopper cover that needs to be removed; mine was stuck there. You should notice some ribs underneath that allow the water to be sucked in while keeping really big pieces out; I got a pair of channel-locks, opened them all the way and was able to slip one of the pieces under the cover and pull straight up, once off you will see the chopper covvered in food. I cleaned mine off and it looked good, but when I put it back and stuck my finger down teh discharge tube and turned the pump, the chpper did not turn. when I put the new one in and did the same test it did turn. If the chopper is still fits in the slot, it can be cleaned and put back and work for several washes while the part is shipped. I went ahead and changed the check valve since I had it opened which is just to the right of the chopper(all you can see is a little slit and some black rubber). Use some needle nose and pull it out. I would not do this unless you plan on changing it, I pulled mine out to look at it and when I put it back so I could order the parts the dishwasher never drained properly. When you compare a new one with an old one you will see what I mean, you can drop a new one right in but the old one you will have to force in (gets water logged over time and expands). This job is very easy and a lot cheaper than a new DW...and your wife will be impressed, so do not be intimidated.

First, I brought in my electric screwdriver and torx bit set. The screws holding the door are torx type. I removed the screws holding the door cover allowing access to the (6) hex head screws holding the dispenser in place. Raising the plastic flap covering the dispenser I removed the (2) electrical plugs from the solenoid. Using my elec/screwdriver and a 3/16" socket I quickly removed the old dispenser.
I cleaned the gasket area with some 409 and a paper towel and slid the new dispenser into place. I used a 3/16" nutdriver to tighten the screws. I tightened the screws in a cross pattern in (3) stages so as not to squeeze the gasket out of position. Screw slowly and the screws will bottom out when the proper gasket tension has been achieved, don’t over tighten.
I closed the door and ran the dishwasher in rinse cycle checking for leaks. After a couple of minutes and no leaks I pushed the cancel and drain button. I folded the plastic cover back down over the dispenser and reinstalled the outer door cover tightening all screws with my electric screwdriver and torx bit. I opened the door and filled the rinse dispenser.
We've used the dishwasher several times since the repair and the dispenser has worked fine.

As I pulled out the old rubber gasket I noticed there was a flat side and a curved side, this is how the new one must go. When I put in the new gasket in I just made sure the flat side (faced out) and it really was very simple. It just fits inside a grove, very easy to install. I compared the to parts (old and new) they were exactly the same shape and length.
I was very impressed with the web site navigation and layout. I was able to zoom in on pictures of the part and there were exact measurements of dimensions.

My dishwasher motor was getting very noisy lately and finally died altogether. (the fwd bearing and seals had worn out. There was a small pile of what looked like white sand under the motor from the wear) I removed the dishwasher from the counter after turning off the power at the breaker box. I then turned the dishwasher on its side. The pump motor is removed by first removing the electrical connector, then loosening the retaining bolt and twisting the motor counterclockwise about a quarter turn. The gasket required a little force to become unseated from the housing but not to bad. Wiggle and pull! Be sure to take a look at the alignment at this point to facilitate reinstallation.To install the new motor, align the mark on the impeller(small delta) with the mark on the motor. Insert Motor into housing and turn clockwise one quarter turn till retaining bolt hole is aligned. Install retaining bolt. Be sure to note the position of the stainless steel screen where you insert the motor. Place it back in position before installing the pump if it is disturbed. I lubed the oring with vaseline prior to install also. The new oring was diffrent and did not feel very tight when i installed , but there were no leaks and the dishwasher is running like new. Partselect had the part at my door the next day with no upgrade in shipping charges and I will use them in the future. This forum helped me choose them and made the task easier to do. Hope this helps you as well.

unscrewed dishwasher from cabinet ...,moved out slightly....while door closed ...reached with long nosed pliers door spring pulled forward...and allowing white plastic part that fits through sleeve and fit new sleeve over it...pulled spring attaching white plastic part and pushed unit back to cabinet and replaced screws DONE.

Checked grinder and cleaned it several times, adjusted blades. Dishes would be clean for approx. 6 cycles, then would not clean. Placed dishwasher on its front and removed the motor. Removed grinder and impeller which I found to be worn so that the blades would not turn on the grinder which caused it to collect food particles. The impeller locks in easily.

I removed the 6 torx screws that hold the control panel on the top part of the door, from the inside, removed the large plastic cover from the control board, removed the 2 big wires that go to the thermal fuse...tested for continuity and foung the fuse faulty...ordered a new fuse kit, reversed the procedure and it works like new.

This product comes in a bottle with a brush like Liquid Paper. It goes on incredibly easy. A second coat might be needed. I wanted to prevent rust from setting in so I covered the scratches and dings. The paint is a little brighter since my washer is 10 years old but it still looks great.

Took the two baskets out and removed the spinners which simply clip on. The bottom center spinner screws on/off using a tab in the center. Then removed four screws holding the filter cover in place. Then removed the one screw holding on the chopper cover and removed cover. Old chopper came out easily. Then rinsed and washed everything down to clean out all of the disgusting stuff that was clogging the unit. Put the new chopper in place, put chopper cover on and everything else in place and it now cleans like it was brand new!

Replacing the actual part was easy. Getting to it was the slightly difficult part. Here's how it went:
Remove the torex type screws surrounding the inner door - this was the easiest part. The screws came right out, but be careful. Removing the screws near the top (was controls) part will release the seaparate top part. Once you do that, it's only held by wiring, and you don't want that to break, so treat this part with care.
Remove the bolt screws holding the outer door to the inner door - so the inner white door containing the dispenser to be replaced, and the outer door separate, but are held together by these bolt screws. You need to remove these to separate the doors further giving you easier access to the dispenser. Some of these bolt screws were in challenging positions to reach.
Disconnect dispenser wiring and replace part - Remember where the wires go, so mark them before removing them. The part is held in by 6 bolt screws. Once removed, the part easily came out. Pop the new one in, screw the bolts in, plug the wiring back up.
Put all parts mentioned previously back together.

Now even though we gave the correct model # of our unit, the part sent did not match 100% what we replaced. There was an extra wire plugged to ours. The connector to plug it to does not exist on the new part. My assumption is this wire is for detection of rinse agent (illuminates a ligth on the front panel if empty) - so we just left this unplugged. The new part has a manual, visual gauge on it anyway which I prefer, so this was not a big deal. This is just warning for others that do this kind of thing.

All in all, it was a well worth it repair. $50 as opposed to $500 for a new unit and installation. We will definitely be looking to this site again for items we feel can be repaired. THANK YOU!

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.
