DU811SWPU4 Whirlpool Dishwasher - Instructions

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).

It is a small plastic piece which serves as a stop on the right side of the upper rack. It is the correct part because it is identical to the left one of the same type. I tried clamping down with a pair of pliers but I am afraid of breaking it. With shipping this two inch piece of plastic cost $20, so I do not want to crack it. I am at a loss as to how to sit in in place.

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

Just click in, you can basically do it with your eyes closed

Snap new track stop into place. Took a few minutes to figure out top/bottom and inside/outside, but no issues

Followed instructions as the videos on this page show.

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

I had to replace the whole sliding system on the top rack. Plus the clips holding it. It snapped. I watched the video and did the steps from Steve. The rack slides better than when brand new. Whirlpool wouldn’t pick up phone but part select did. So thank you for being there so I could fix the rack and be able to use the dishwasher again.

I manually attached the track stop to the right track in the disheasher.

Getting the dishwasher out was easy. Getting to the impeller was easy. Getting the impeller off of the motor shaft was the difficult part. I had to use my Dremel tool with lots of cutoff wheels to cut the impeller off of the motor shaft a little piece at a time. It appeared to be rust on the motor shaft that was causing the impeller to not come off. There is not much room for the Dremel so be careful not to nick the pump housing or cut into the motor shaft. Keep the vacuum close by to clean out the plastic impeller shavings. Clean the rust off the shaft with steel wool, fine sandpaper etc. Assembly was easy once everything was cleaned up.

Disconnected hoses (2) from pump housing. Disconnected pump housing from motor (3 allen screws, not too acessible). Unscrew spray arm from pump housing (this is done by hand; no tools as the "nut" is about 3" diameter and made of plastic) Open up the pump casing and replace impeller and the bearings on each side. The thing that takes some time is to mop the water that comes off at almost each step. There is probably an intelligent way to drain everything first. I did not order the large seal (kind of a large rubber donut, larger than a donut) between the arm and the pump and I shoiuld have as it was difficult to keep the old one from not leaking: Since by hand you cannot tighten the large nut very hard and tools could damage or break it. Applying upward pressure on the pump while tightening did it. (The pump and motor are all mounted on flexible mounts, like the heavy hoses connecting to the pump housing, so that there are no vibration.)

I poked the old gasket with a fork tine so I could get a grip on the old gasket as I didn't have pliars, pulled it out in less than 4 seconds, folded the new gasket in half and started center top of the slot the old gasket was in and pushed the new gasket in on each side from the top to the bottom. Very easy. I'd say it took me longer to open the package with my teeth than in doing all of the above.

After getting the pump and motor off of the dishwasher, I used a screwdriver and small hammer to break the impeller off of the motor shaft. The shaft was corroded and pitted real bad but this doesn't matter because the shaft of the impeller actually goes through the seal. I removed the old seal and replaced it, slipped the new impeller back on the motor shaft and put the pump and motor back on the dishwasher. Our local repair man told us it couldn't be repaired and we needed a new dishwasher. I had the parts from Part Select in 2 days. The parts were less than $35 dollars and repair very simple. The person on your comment section on how to fix it that said to break the old impeller off of the shaft made the job very simple.

took the old arm off in a minute and replace with the new on,total time about 5 minutes and it now works great

After cleaning the filter located on top left of door(used a screw driver to pry out) and following the install gasket video problem solved.
