DU1148XTPB1 Whirlpool Dishwasher - Instructions

I shut off the power to the dishwasher, then I removed the front panel under the door. On the right side just behind the electrical box there are two wires going up to the hi-limit thermostat, (you may need a small mirror to see it), remove one screw that is holding the thermostat bracket, unplug the wires from the old thermostat and install new one. Screw bracket and thermostat back to the underside of the dishwasher, reinstall the front panel, turn on the power, done.

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.

I couldn't get dealer to order part, so went on line to see what was available. Found model and picture of part needed and ordered. It came in 3 days. Took part out of box and compared to part the needed replacing. It was a match. Removed old basket and replaced with new one. It works great and siverware stays in basket until put away.

removed both upper and lower racks. removed lower spray arm(left hand thread) removed "water delivry tube and upper spray arm. removed torx screws on pump cover. removed inner chopper cover. Chopper assy had come apart and was full of food crud. cleaned out and installed new chopper assy. kind of tricky don't force it. reassembled. tested OK.could tell sound of more forceful water pressure

I released the heater element from the clips on the bottom of the waaher tub. I pulled the unit out from the wall and disconnected power. There are two slip on wire terminals on each end of the heater element accessible from the back that need to be removed. One of them was badly rusted from leaking water, which had caused the short, and had to be replaced. These terminals and the crimping tool to install them are available at any home center. I removed and discarded the old plastic nuts since one of them was damaged by arching from the short circuit. Moving around to the front of the dishwasher, I removed the old heater and installed the new one. I had ordered new rubber washers, but the new heater came with them already installed. Since one of the old ones failed and caused the leak, they are a good thing to keep around as spares anyway. I installed the new nuts and tightened them to enough to ensure that the washers made a good seal. I reconnected the wire terminals to the heater, reconnected power and moved the unit back into place. The circuit opening when the heater failed caused a "call for service" error and the controller would not allow the unit to run. You will know you have this by the "CLEAN" LED flashing seven times. Clear the diagnostics by pressing the buttons for "HEATED DRY", "NORMAL", "HEATED DRY", "NORMAL" and after the controller resets, the dishwaher is ready to run. It's worked like new ever since.

First: Turn power to the Dish washer OFF, then remove the two panels at the bottom of the dishwasher.
Two: remove the Door face panel for easier access to the inlet-Valve.
Three: remove screw that holds Inlet-valve bracket.
Four: slide Inlet valve bracket left and back to get out of slots.
Five: Holding the Inlet-valve forward loosen and remove water line (copper tube nut / pressure fitting).
Six: Remove two wire clips
Seven: Remove platics hose (Spring Clamp)
Replace Inlet-Valve and reverse process///

Turned off water and disconnected line, then disconnected drain, turned off power and slid dishwasher out and turned turned upside down and removed hold down bolt ( it is a 3/8 head bolt) removed wire from motor and twisted motor assembly approximately 1/4 turn counter clock wise and removed old motor and seal assembly reinstalled new motor with new seal and rewired. Turned washer back upright and removed filter assembly and lower jet arm, removed cover for food disposal and reinstalled disposal blade back on pump drive reinstalled cover and filter assembly and jet arm. Slid unit back in place and anchored down to cabinet and turned water and power back on ran washer through a short cycle to clean any soap build up that was left inside and that was it, it all works just like new.

Turned off power, turned off water supply and diconnected, slid out dishwasher. Removed the spray wand and tilted dishwasher to access the two nuts and disconnet the wires. Removed the two nuts using a socket. Removed the old heating element and replaced with the new one secured with new nuts ( the old ones were fine but since I bought two new ones why not). Pluged the wires back up slid the dishwasher back in hooked up the water reinstalled the spray wand cut on the water and power. Good as new.

Replaced electronic control panel first which had an obvious defect (burned terminal). Still no power. Replaced fuse and works fine now. Took lots of reading to find out the dishwasher had a replacable fuse. Even the appliance store didn't know.

Via your web-site I was able to download the step-by-step screen-shot pictures. I was really surprised on how easy the detailed photo screen shots made the repair really easy! Thanks for making this repair a piece of cake. If I should ever need additional parts for any of my home appliances I will certainly order my parts through PartSelect.

Got Maintenance Flyer out an read about problem
Removed access plate
Disconnectd water and drain
Removed anchor screws
Pulled unit out and disconnedted from Electric
Flipped on it's back
Ohmed out all heat related items and found discrepency with Thermisitor resistance
Ordered and received Part
Changed out Thermisitor
Checked wiring to Heater and replaced connections
Hooked electric up
Ran Diognostics per Maintenance flyer and cleared fault
Hooked back up and ran like a champ

The reason it took so long is because I put the old thermisitor back in and tryed to run the diognostics just to make sure that was the problem

First I had to remove the upper dish rack from the dishwasher. This was the most difficult part of the entire fix. I found the screw which holds the spray arm in place, Removed it and took off the old spray arm. Then I replaced the seal and put the entire thing back together, put the screw back in and replaced the rack. Then I ran a load of dishes and discovered the machine works just fine now.

Thanks to the previous review of this part, I was able to figure out how to do the replacement myself and saving $150 on a service call. The part is super easy to replace. Remove the screws on the door, lift the outside piece of the door up and off the hinges and then unplug the old piece. I had turned off the electricity to the dishwasher to avoid getting shocked. There were 4 hex nut screws holding the part in, removed those & popped out the old part. Installed the new one, put the door back on and the screws, turned it on and no leaks. This part was so easy to replace, even for a 52 year old woman like myself!

I had a repair guide for my dishwasher which helped. First I removed the water distribution system inside the dishwasher and then removed the door panel. Next I removed the front bottom access panel. I placed a pan under the pump and hoses to catch water when I removed the outlet hose. Very important here! One must remove the pressure switch from the outlet port or else you can't get the pump clear of the washer tub. Next I removed the drain pump by releasing the catch and turning the pump counter clockwise. Now for one of the hard steps. I had to remove three pins which hold the pump assy to the wash tub. Two of them are out of sight so you have to weave you hand past all the hardware and "feel" for the back two. At this point the pump assy just lifts out. Remove the motor /pump by removing one bolt and turning it counter clockwise and withdrawing. I put the new one in. Don't forget to put the pump screen in as I missed this and had to redo the job. Reverse all the previous steps being careful to keep the motor guard out of the pump seal area. Use lots of silicon seal grease and check for leaks on first power up. It took me a couple of adjustments to get a leak-free seal.

Removed dishwasher from under the counter and took it to my shop. With the washer on its side, I removed the motor, then the impeller and seal. I then disassembled the motor and replaced the front bearing(purchased separately). This required an arbor press. I then reassembled the motor and installed the new seal and impeller. Reassembled in reverse order. Reinstalled under the counter and made conections. Checked for leaks and proper operation.
