DP840CWDB4 Whirlpool Dishwasher - Instructions

i determined that the impeller was not free. ordered and installed an impeller kit which included a new bushing, which was the culprit. it was a fairly simple fix, needing only to remove the pump housing from the back of the motor. access to the impeller was by removing the screw-in, x shaped connection on the back side of the impeller housing. runs like new again. the fix was far less expensive than a new washer.

All I had to do is lay the shield over the top and sides and used a couple of clips to hold in place as it was slid under the counter top. It couldn’t have been easier.We had searched everywhere for this replacement shield and parts select was the the only ones that had it. Very good service and fast delivery,

Had to be careful positioning the spring without breaking the hinge pin. Requires a certain amount of patience.

Turned off electricity. Removed the interior door cover. Removed door switch. Replaced switches & reversed process. By the way - I am a woman & diagnosised, ordered part & fixed it myself - I have no experience in this field. THANKS for all your information on your site.

My husband did the repair. He sucked the water out with the wet/dry vac. Layed it over on the front and removed the pump motor and replaced it.

but the pin in and add the pin though the 2 tabs close door on it open it up move the springs backwards to the door

All I had to do was remove old door panel and retainer and I replaced with the new.
PartSelect were great. I highly recommend you guys.

Pulled off the bottom trim, slid the old panel off and put the new panel on. Then popped back on the bottom trim.

remove star screws holding inside door panel. remove plastic cover that protects latch assembly. hook one end of spring on stationary pin on inside of slider bar. Hook other end of spring on pin on slider bar. replace cover and door panel.

Replaced door gasget took 5 minutes tops. Ran cycle and still had leak. Called local repair person. After thoroughly checking out the dishwasher and running soapless cycle determined problem to be soap build up over time. He ran a commercial cleaner through a complete pots and pan cycle. No more suds and no more leak repair complete. Did not actually need door gagset but it was super easy to change and delivery service was great.

I used the screwdriver to pry the old lid off of the horizontal pin upon which it rotates. One must be careful before removing the old lid to note how the return spring is deployed. The short legs on the spring must be in the lip of the lid before you snap the new lid onto the horizontal pin. It was helpful to lubricate the two catches on the lid that snap on the pin with some liquid soap before attempting to snap them on the pin. After the lid is snapped into place and the short legs of the coil spring are in the lip of the lid, use needle nose pliers to attach the other end of the coil spring to the pillar where it was before you removed the old lid. There are videos showing how to do this on Youtube. The spring part is a little tricky. The video makes it look a bit easier than it is..

Replaced the impeller using the kit. Had to brake the impeller since it was stocked due to rust.

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 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.

after removeing the mounting and trim screws,water lines and associated wiring, the unit slide easily from under the counter then the fun began.
After several years of being exposed to the terrible water here the parts had become covered in lyme scale.
to make a long story short, most of the parts came out with minor difficulty however the pump motor shaft had corroded and lodged into the pump impellar.
This made removal of the pump motor impossible with out cutting off the end of the impellar and driving the pump motor shaft out.
This is NOT something you want to do.
It seems the engineer who designed the pump motor had it's casing made of plastic.
Driving the pump motor shaft out of the impellar caused the back of the motor houseing to break thus rendering the pump motor useless.
Lesson: If it becomes necessary to cut off the impellar of in the pump housing you must completely split the impellar in two parts.
This I repeat is NOT something you want to do.
I recommend replaceing both motor and pump assembly as a unit.
