Wash Impeller WP902461

The hardes part was to remove the retaning nut (#34 on the diagram). There isn't enough grab on it and it is quite flimzy. Be prepared to butcher it if necessary. I resorted to wedging a screwdriver between the top flange of the nut and the spray arm and that gave me torque I needed to undo it. Luckily, the nut survived and could be reused.
Once the nut is off, everything else is pretty straightforward, just pay attention what goes after what and in what orientation (take notes if you must, however, I did not and got away with it). My machine has not been serviced in years and there was calcium deposits everywhere. If your machine is just as bad as mine, I strongly suggest to remove everything that can be removed and give it a nice vinegar bath or use other products designed for calcium removal (ask your wife what she is cleaning the bathroom with, it will most likely do). Bottom line, the cleaner the parts are, the better it will pump.
In my case, it was the calcium that eventually killed the impeller #14 and made it spin on the shaft (no pumping therefore).
Inspect all the parts for heat / wear damage so you put one order for everything you might need.
Secondly, the screw #12 that holds the impeller #14 on the shaft is a tiny screw and it is originally secured with a threadlocker. Make sure that the internal thread in the shaft and the screw are absolutely dry before applying loctite.
Thirdly, there is a plastic ball that sits in the cavity in one of the disk-like part (not shown on the diagram). Do not loose it and make sure it is put back.
That's pretty much it. Once properly cleaned and repaired, the machine washed like brand new. Pretty good for less than $50 investment in parts and a week downtime. . .

Turned off the circuit breaker. Removed the two lower panels below the door. Removed the two racks from inside the tub. Removed the lower rinse arm, then unscrewed and removed in stages as much of the washer components from the inside bottom of the tub. Last item was the unit that screws into the base of the tub, was loose but would not come out, then I realized I needed to disconnect the water lines from underneath the tub. Then I was able to lift the pump/motor assembly out from inside the tub. Disassembled that until I reached the wash impeller, and saw that the shaft was no longer rectangular, but rounded out and spinning freely which was why the water was not being pumped out. Also found a small flip top from a can, no idea how that got down there, but that was what was making the loud scraping noise as the was impeller tried to spin. Reassembled everything and unit now works fine (and much quieter!) Never had to take the dishwasher out from under the cabinet and if I had to do this again it would only take 30 - 40 minutes - live and learn!

I unscrewed the parts of the washing tower, then removed the housing and filters above the impeller. Lastly I removed and replaced the impeller and "o" ring. This repair went fine. Unfortunately another part (blower) let go and I decided not invest any more time or money into this machine since it was so old.

Removed and dismantled the pump assembly and found the impeller shaft was broken. Found the correct part number, ordered the part and it works like a charm. Assembly reverse of disassembly. Replaced the pump gasket and outer door panel(dent)as well. Great store!

Removed the 6 screws holding the pump and motor assy. Disconnected the two hoses and wiring connector. Removed the motor and pump, removed the pump parts to get down to the impeller. Removed the old impeller (one screw) and installed the new impeller. Put every thing back together and it worked fine. Every one is happy!

My husband does all the repair work himself so he tore it all apart but it's hard to find parts for a 23 year old machine. A store about an hour from our house said they had the part. When we got there it was the wrong impeller and it was going to be $30 to order it in. I got home on that Weds. nite ordered it and had the part 2 days later on that Friday.My husband had the part in and the dishwasher running within 20 minutes. Thrilled with the fast service from you and my husband :)

i removed the bottom spindle inside of the washer compartment. laid the pieces out in order of which they were removed. found the impeller was busted where it attaches to the shaft of the motor. screw was missing but found it laying in the bottom (there is a screen that filters the water as it drains). replaced impeller and put parts back together in order. good as new.
