DU1055XTVS1 Whirlpool Dishwasher - Instructions

I read information on this website about the function of the high limit thermostat. I found that it was the problem by disconnecting the two wires on the thermostat and straight wiring to bypass it. This allowed the machine to work properly so I ordered the high limit thermostat. To replace the part I used a screwdriver to remove the instrument panel and replaced the high limit thermostat by disconnecting the two wires from the old thermostat and connecting the wires to the new thermostat. I then replaced the instrument panel. My machine is working properly again..

I removed the screw holding the spray arm in place, removed the defective spray arm and installed the new replacement. I also chose to replace the smalll plastic bushing that the arm spins on. It took less than a minute to do all this.

Removed front cover, (8 screws) Removed 4 screws that hold the dispenser in place. Removed and replaced the dispenser, installed front cover and screws. Checked for leaks.

Removed both baskets. Then removed 1 Phillips screw for upper rack water supply. Unscrew lower washer arm. Twist lower water supply clockwise to disengage from upper piece and from retainers. Remove 4 torx head screws and remove strainer assy. Remove 1 torx head screw from chopper cover and pull out chopper cover.. Pulled up on chopper screen and removed all broken pieces. Pulled on chopper itself to load the spring and put chopper in place. Make sure it goes in outer most slot. Reinstall in reverse order. Works perfectly.

Took lower impeller off and cleaned. Replaced the little plastic piece and voile - good as new! Was ready to buy a new dishwasher but thought we would try this first. Working as good as new. What a savings eh? Thank you part select for your great service!

Removed 6(six) torx head screws backside of top control panel. Removed top of panel to access contol board. Unplugged clearly marked wire plug-ins. Unsnapped control board, snapped new board in ressymbled panel.

Installed brackets

We had to pull the dishwasher out the get the heating element brackets loose underneath. We had to put the new heating element in and then we had to figure out which code to program in to make it reset. the last one listed on the installation instructions was the one that worked. I think it was heated dry, normal, heated dry. It would be very helpful if the reset instructions were put in the manual by whirlpool. I am very pleased with my part that I ordered from PartSelect. It came within 2 days of placing the order.

Remove power to the machine. My particular installation did not require physically removing water and drain lines. Remove the dishwasher from the cavity. Put a towel or two down on the floor. Lay the washer on its face on the towels and this orients the motor in the up position on the bottom of the washer. CAREFULLY unplug the motor wiring harness but if possible, leave the heating element connection in place as spade connectors tend to lose their grip with multiple engagements. Remove the single bolt located between the motor and stainless bottom of the cavity that locks the motor in place. Leave it in the cardboard shield, that really helps in reinstalling it. CCW rotation of the motor disengages it from its housing. Work the motor straight up and out of the housing. This was the most difficult part of the entire process due to the metal housing not quite clearing the plastic pump housing where they mate, but its do-able. Nothing should have to be forced. Now you have the motor in hand. Be very attentive how and what order you disassemble. Remove the back of the motor housing to block the armature to remove the impeller. DO NOT NICK THE FIELD WIRING IN THE MOTOR. I believe the threads were left hand but I don't remember the rotation. They do tighten in the direction of the motor rotation though. Carefully pry the seal out of the pump housing with many short lifts as to not mar the housing itself. Added a little dishwashing detergent on the outside of the new seal and carefully pushed it into place with the end of my screwdriver. Don't cut yourself on the metal insert in the center of the seal.Reassemble the impeller to the shaft WITH the spacer that comes with the new impeller kit. Make sure the impeller is tightened down completely to the end of the threads to insure proper clearances when reassembled. Don't force or over tighten. You'll feel a positive stop. Reassemble the motor to the housing Lubricate the housing o ring seal on the outside with a VERY small amount of dishwashing liquid lest you create a suds factory on startup. Replace the holding bolt on the pump housing. Reconnect the motor leads and heater element if removed. Stand the washer back up. There will probably be water around the door area from the pump when the machine is returned to the upright position. Reconnect lines and check under the pump housing for leaks while in operation being careful not to get into moving parts or electrical connections. Good luck.

Due to the posts on this site, I took the advise of replacing the chopper assy. Old chopper did not look bad and seemed to function. Apparently I was wrong. After new chopper was installed, dishwasher worked fine.

I started my repair by replacing the most likely and least expensive cause of the problem and replaced the bimetal thermal switch. The PartSelect video was very helpful on doing this repair. However, this did not correct the problem and I decided to try again and risk replacement of a much more expensive item, the electronic control board. There was no video for replacing the control board but I had gained knowledge and confidence from my efforts with the thermal switch. I ordered the part, it arrived in 2 days and I successfully installed it with no difficulty. My dishwasher has worked fine for several cycles now so I consider the problem fixed.
