DU1055XTSS2 Whirlpool Dishwasher - Instructions

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.

The repair went fine just called my grandson in law and he did a good job and he said it was easy.

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.
