GU1200XTLB3 Whirlpool Dishwasher - Instructions

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.

The part snaps on using two plastic retainers (included). You have to pull down gently on the feed tube at the top of the dishwasher to set the top retainer. After that it's a piece of cake.

I turned off the power to the dishwasher, removed the kick plate, raised the front levelers, disconnected the electric to the appliance, turned off the water supply to the appliance, disconnected the water supply, disconnected the drain system from the garbage disposal, unscrew the appliance from the countertop, then I remove the appliance from underneath the counter. I then tilted the appliance back and then in screwed the plastic retainers that held the heater element in place, removed the old one, replaced it with the new one in reversed the whole process

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.

Checked the house circuit breaker, verified AC to the box under the dishwasher, removed the screws around the inside door cover, and removed the cover. Removed the outer circuit board cover. Used a multi-meter to verify AC to the door latch, and to verify the latch switch was working. Verified AC to the thermal fuse above the circuit board when the door latch was closed. Verified no AC on the other side of the thermal fuse. Removed the thermal fuse connections with pliers. Used thin flat blade screw driver to unsnap the thermal fuse assembly. Used multi-meter to verify no continuity through the fuse. Ordered the fuse assembly and replaced. Reconnected the thermal fuse connections. Manually closed door switch and saw lights on the display panel, and dishwasher started. Replaced all covers and works great.

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.

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

Found the gasket to be wearing out. Once I got the part I took everything apart inside to find that I could have just taken the dishwasher out and replaced from the bottom. It was not difficult, but I've installed a ton of dishwashers. For the average homeowner, this is can be a difficult job since it requires plumbing and electrical skills.

Looked at other side of top rack which still had the stop. Just had to orient the direction of the stop and push it firmly onto the rack arm. Took a couple tries, but it went in and locked. Works perfectly. Inexpensive and easy fix to to very annoying problem.

Pulled front panel and replaced door switch. Extremely easy but did not fix the problem.

I did not relize that the drain hose was in two parts. Naturally I ordered the wrong half. So after I relized my mistake, I re-ordered the correct part. Once the correct part was received the repair was easy and went well.

Our Kitchenaid dishwasher was leaking so I called a repair service. I gave the model number and serial number over the phone and explained the problem. I was told the rubber gasket would need to be replaced. When the repairman came 5 days later he told me that the gasket needed to be replaced but he didn't have a new one on his truck. He ordered one and said he would be back in a week to repair the dishwasher. That took 10 minutes at the most. He then gave me a bill for $200.49 ($71.49 for the part and $129 for the labor)that I had to pay right then. I wrote him a check so he would leave and immediately called the repair company to tell them the price was outrageous and that I had never before paid for a repair before the work was done. I was simply told it was their policy. I then told them I was stopping payment on the check - which I did. I checked on-line for the part and found your web-site and the the part I needed for $27.62. I ordered it on a Monday, it arrived on Tuesday and my husband easily installed it that evening. Thank you, thank you, thank you!

I unscrewed the dishwasher from the counter (two screws under the countertop), and pulled it out about a foot so I could access the friction sleeve. I used a needle nosed pliers to slip a spring latch off the door. Then I slipped the new friction sleeve on and reattached the spring. Tested the door. Success! Super easy. About 5 minutes of work.

put new hose on, very easy.

Removed the old tines by pushing out the clips on the end and then installed the new tines and applied clips - took 10 minutes worked slick and the washer basket looks to be brand.
