WU3000X4 Roper Dishwasher - Instructions

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.

unhook electric & unscrewed 2 metal screws unhooked water line,& replaced new one & reversed hooking up all it worked fine

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.

Since there were no printed instructions, we looked at the photo schematic.
Reassembly using the photo was easy by putting the old rack alongside the new one and adjusting the new rack spacing to match the old one.
We also had new wheels which snapped on.
We were delighted to repair and replace this good, older dishwasher rather than purchase a new one!

All pieces just snap off and the new one just snap right back in place.

Remeber take a little time to do your repair correctly.

It is cheaper to repair an appliance than it is to replace.

installed a new rack

I removed the three screws holding the motor on the housing. Then I took the two hoses off and from inside the washer I unscrewed the ring at the base of the wand that holds the housing in place and removed it. I then replaced the impeller and seals and reversed the process to put it back together. Cost me 26.00 for parts and shipping. I couldnt imagine what anyone else would have charged. I will do business with PartsSelect again in the future.

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.

We read your help site and was able to find what was causing our water filling probelms. Order the valve intake part and made the repair and the dishwasher works like new. You saved us a repair bill from the professionals and they couldn,t done a better job. I will recommand to site to everyone. Thanks Again

The lower dish rack rolls directly out of the dishwasher without problem - there is no permanent attachment. The new rack comes as a kit, which includes the 4 required dish rack wheels (Part # 6 in the diagram). One part (only) from the original dish rack needs to be removed and re-installed on the new rack - the upper spray arm tower (Part #5 in the diagram). That is easily removed from the original rack with a 1/8 counterclockwise turn, to disengage the 'feet', and installed on the new rack with a 1/8 clockwise turn. The kit is designed to allow for use on multiple models, so there are 'extra' parts left over, after it is used for the DU8500XX-2 dishwasher. These can be discarded.

I USED A PLUMBER

Just took old panel off and went side to side and then slide panel under front trim. Of course it was easier because the bottom door trim was off and now I have to find that replacement part. Not having any luck with that!

Snapped on the rollers, removed the center part from the old rack that sprays the water and snapped it on the new one. We then bent the back row down so it would acomodate my larger items. My old rack had that feature. You could either have the rack up or down. Now l
ooks beautiful and works perfectly.
Could have used some directions though.

Both springs (8066018 and 3368999) were replaced as recommended in your troubleshooting guide, but did not resolve the problem. Finally the Dual Motor, 3374501, was replaced. During the above, the plastic face of the door fell off, which created a nuisance task before proceeding to fix the original problem. However, while replacing the motor, I realized the purpose of the two, T-shaped studs sticking out of the motor. It is absolutely necessary that these sit inside the slots which engages the sliding plastic cover, which is spring loaded, in order to engage the release of the soap dispenser door. It was truly a learning experience, but I got it done.
