DU400CWDB2 Whirlpool Dishwasher - Instructions

The pump drain hose had been eaten by a rat searching for bits of food. Hose was easy to replace. Then after the repair, we ran the dish washer through its cycles and thennoticed water leaking from under the cabinet from the sink-side. The rat had also chewed the hose connecting the pump drain hose to the sink. Fortunately our hardware store had that hose and we could access that hole from the sink side.

I watched the video link sent in an email and followed exactly what they did in the video. I removed the star head screws holding the door liner in place. Then removed the protective cover on the inside. I disengaged the component holding the latch in place. I replace the component that holds the latch in place and then snapped the new latch in place. I turned the dishwasher dial until the prongs were fully retracted. I replace the protective cover and then put the door cover back in place. I initially only placed the left bottom star head screw until I was sure that the latch was going to release. I tested that it was working properly by slowly turning the dial on the dishwasher control. Once I knew it was working I replaced the rest of the screws.

The repair went well with the major problem being I replaced the drain hose without removing the dishwasher from it's position. Due to this I removed the drain end with out being able to see the hose and put it back on by feel. Over all I was back up and running with in 30 minutes and everything has worked very well so far.

The old spring on the detergent dispenser box door failed and the dispenser door would not pop open at the right time in the wash cycle.

Ordering the new spring was easy on the website. Need dishwasher model number, stock number and serial number.

Hint - Order at least 2 springs! They are not expensive.

I followed the instructions in the video. I could get the spring on the spindle correctly but could not get the two spring prongs to catch to create spring tension on the door without using a thin knife blade to carefully push each prong to where it caught on the dispenser door.

I needed to slide the prongs slowly and carefully to get them to catch on the door. This distorted the spring. That's why you really need two springs. I then used needle nose pliers to pull the latching part of the spring to catch on the inner door. That distorts the spring, too.

So you really need two springs. One spring to learn how to do it and a second one to replace the one you distorted as you learned.

Take care

Very easy repair. I gently removed the rubber seal at the top of the tub. here I found the 2 holes to screw the new plate into place. Put the seal back over the hole and job done. Thanks for all the help from the very supportive staff. Yes, a woman did this repair. Dishwasher working like brand new!

No Water supply to Dishwasher. Turned off main Supply valve under sink.First took off old Diswasher supply valve and repaired it by cleaning it and it worked for two weeks. I ordered the part, but then cancelled it and Partselect service was great and cancelled it immediately. After it went down after 2 weeks I re-ordered it and it came in 4 days.
To Take this part off I removed mounting scews with nut driver, disconeected electronic plug connector, removed the compression fitting from the water supply and removed the outlet hose..reversed all of the above to install.

Followed the helpful instructional video that is included in the installation instructions here on this site. Had to drill out impeller to remove it due to 20 yr. old dishwasher w/ signs of hard water attack on the motor drive shaft. New part installation was quick, once the old impeller was completely removed and internal housing was cleaned.

Before installing new parts, make sure to flush out & clean internal pump housing to remove any loose debris and/or signs of rust, and carefully clean motor shaft & seal seat surface.

Also found heavy limescale buildup and soap residue on pump seal grommet & seal surface on the upper lip of the pump housing. Grommet is discontinued, but it cleaned up well along w/ seal surfaces, after soaking in white vinegar and employing a light scrub along the circumference of the seal (Not radially or perpendicular to the seal surface).

I ORDERED THE PART THAT WAS EASY BUT WHILE THE MACHINE WAS USED FOR HOW LONG I DON'T KNOW WITH OUT THE CAP IT GOT FILLED WITH FOOD AND JUNK. FIRST THING I HAD TO DO WAS EXAMIN THE DOOR AS TO HOW I COULD CLEAN THIS THING OUT. I REMOVED 6 SCREWS THAT HELD THE DOOR TOGETHER AND PULLED EASY CAUSE I DIDN'T KNOW WHAT I WAS GETTING INTO. NO PROBLEM THERE WAS NO ELECTRIC PLUGS HOOKED TO THE DOOR. I TOOK IT OUT SIDE AND STARTED USING VINIGAR AND POURING IT INTO THE HOLE AND SHAKING THEN TRYING TO GET IT BACK OUT. WELL THERE IS ONLY ONE POSITION THAT WILL LET THE VINEGAR BACK OUT. I HAD TO HOLD IT SIDEWAYS THEN TILT FORWARD AND IT WOULD RUN OUT AND BRING SOME JUNK WITH IT. THIS WAS A TIME CONSUMING PROCESS BEING YOU COULD NOT SEE INSIDE TO KNOW HOW MUCH JUNK WAS IN THERE. JUST POUR AND DUMP. AND DON'T FOR GET TO SHAKE TO LOOSEN ANY THING LEFT INSIDE.LOL I WAS VERY PROUD OF MYSELF NOT KNOWING FOR SURE IF I FIXED IT OR NOT BUT I TOOK A SHOT I HAD. I DID SOME SCRUBBING AND DEGREASING ON THE UNDERSIDE OF THE BOTTOM OF THE DOOR BEFORE I REASSEMBLED IT. THAT WAS EASY AND I CROSSED MY FINGERS ANY WAY. I GOT OUT MY NEW PART AND THE JET DRY I BOUGHT AND STATED TO FILL THE DISPENSER AND IT TOOK HALF THE BOTTLE.YEA !!! I PUT THE CAP ON AND COULDN'T WAIT TO DO A LOAD OF DISHES. EVERY THING IS LOOKING GOOD NOW. THANK YOU PART SELECT FOR MAKING GETTING THE PARTS I NEEDED SO EASY AND SHOWING DIAGRAMS SO I HAD THE RIGHT PART. I COULDN'T HAVE DONE IT WITH OUT YOU.

Pulled the old gasket out with needle nose pliers, cleaned the slot for the gasket, installed the new gasket, needed no tools. This repair took 5 min.

I ordered a dishwasher soap dispenser "lid assembly". When it arrived, it was not an assembly at all but only a lid. I had to reorder a pin and spring, When i finally had every thing, it was an easy repair.

WATCHED THE VIDEO FOR 2 MINUTES. REPLACED THE 3 PARTS IN LESS THAN A MINUTE. THANKS FOR THE VIDEOS.

Easy fix. It’s a screw on by hand piece.

Was a simple task to perform, a child could have done it. The technical skills diagnosing it was a bit hard though. The skills finding the culprit was indeed simple. Rubber was torn. Dishes would not come clean especially on the top & would not dry properly. The rubber piece being torn in half made it hard for the water & soap to despense to the top through thh center plastic tube, but now it cleans great. Thank's
Now to find out why it won't dry properly at the heating element is another task. It leaves water droplets on the dishes.
Once I got the rubber screw on attachment installed the dishes are clean & dry now & no water dropplets on the dishes.
The water dispenses up to the top like it suppost to throught the small tube to wash the upper rack dishes.
The wife is happy now she doesn't have to clean & dry them by hand.
Thank's so very much!!
Now on to the next project in hand to submit later on.

door gasket old the vent was pluged up full of black slime cleaned out and door stopped leaking

New gasket did not fix problem. Cleaned air vent cover for steam to exit. Gasket not the problem but new one looks good. thank you
