How to Troubleshoot & Replace Whirlpool AP6024061 / WPW10780877 Pump And Motor Assembly

Your video was a big help, thank you. I took the unit apart to find what I would need, a new grinding wheel and blade, etc. Decided to just replace the whole unit, rather than just the pump and smaller parts. Made it much easier. Took me about 1/2 hour to change it out. My pump had been making loud noises for about 2 months, I figured it was only a matter of time. 

Ordered a new pump assembly. Replacement was relatively easy especially with the aid of the AppliancePartsPros videos. 

I researched what would cause the dishwasher to make that kind of sound found out what it was looked up my manual online got the part number order the part from appliance partsPros.com watch the You Tube video and install it myself it was pretty easy. 

Kitchenaid Dishwasher (5 years old...) Cleaning out the grinder gunk didn’t eliminate the noisy operation so I elected to replace the motor/sump assembly including the pump. Parts arrived on time and the excellent video made the repairs relatively painless. Took me approximately 90 minutes to complete the repairs which was a first-time event for me. No more noise. I’m sure an experienced technician would easily complete the repair in less than one hour. No reason to pay extra for the ‘Kitchenaid’ brand given all parts are from Whirlpool with the same warranty regardless of the model. Sad that these newer appliances have such a short life! I will definitely use Appliance Parts Pros again if/when needed. 

I replaced the asm-sump/motor 

Disconnect electrical supply, remove pump & drain hose connections at wash sump assembly. Remove optical sensor(twist release), pull 3 sump assembly slot retainers that hold sump to tub assembly, push complete assembly up thru the tub opening, disconnect motor harness at motor quick disconnect. Clean flange of tub, lightly lube new sump assembly outer gasket with jet dry liquid or liquid soap. Press sump into tub opening after connecting motor harness to motor, carefully aligning keyway in tub to sump ,(you may need assist holding the sump in place) then install all 3 slot retainers and reconnect optical sensor, pump assembly, drain hose and electrical. run rinse and check for leaks 

Ordered a new sump pump thru Appliance Pro's and watch their video on replacement. My biggest issue was getting the dishwasher out from under the counter. We had laid new 3/4" think Tile in front of it. There was just enough room barely after pulling the front legs all the way up using a quarter inch ratch to get it up and over the tile lip to get it out from under the counter. Once that was accomplished, the actual motor replacement was super easy. My upper spray tube was more complex then the one in the video. And I did not remove it. When I got the pump loose, I rotated it to remove it from lower piece that carries water up to the upper and middle water spray bars. Reinstalled it the same way I took it out. Used soap to lubricate the gasket as shown, put the three wedges in to hold it and went back together easy. I actually had the dishwasher on it's side when I inserted the motor and pump so that I could see while I rotated the motor a quarter turn into the lower arm and locked it into place. Now the dishwasher washes better than ever and is very quiet. 

1) Watched ASM-Sump/Motor assembly replacement video 2) Followed the steps listed in video 3) The large o-ring seal was a little difficult to compress but with some finesse I was able to insert the shims completely. 4) Washer is now quiet again.
