CDB4000AWW0 Magic Chef Dishwasher - Instructions

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.

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.

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.)

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.

New one snapped right into place.

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.

I USED A PLUMBER

As described with instructions, removed original "bearing," installed replacement, removed original spring, installed replacement springs. Not difficult.

Reassembled lower access covers using the new screws purchased from parts direct, perfect fit replacement. Hardest part remembering how they fit Dishwasher.

Crazy Glued it together until we received the new part, but it fell off again. My husband installed the new piece and said it only took him about 2 minutes. You just take off the end cap and pop in the new piece and adjust to match the one on the other side of the rack. He said it was extremely easy and no tools required.

I had done a door on another brand a while back and thought it would be the same, WRONG. All I needed to do was 6 screws in the lower panels. It should have not taken me longer than 30 minutes.
2 screws in the floor panel, 2 screws in the lower L shaped panel, 2 screws in the bottom of the front panel to be replaced.
EASY

I just snapped the old one off and snapped the new one on..

No tools required except possibly a small screwdriver to help remove stop in end of rack; part easily installed by hand and stop re-inserted. Finished in several minutes. Thanks!

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

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