Whirlpool WP99001791 Dishwasher Pump Filter OEM Part

Searched on this site and found likely cause and solution to problem. After watching APP video, I was able to remove dishwasher filter and confirm clogged filter. Ordered the new part and it was shipped quickly. Reinstalled it per video instructions and it worked perfectly! Thank you APP.com for making me look like an appliance repair expert on this and several other projects. This has saved me lots of money over the last few years, and kept my slightly older appliances in working order and out of the landfill!

It was a easy fix.

Replaced the filter.

First took apart to confirm broken pump impeller. Indeed it was. Ordered the pump/impeller kit. Waited 6 days for it to arrive. Installed kit as shown on video. Believe it or not had an extra part, a flat plastic 5" disc which showed its self upon removal. Has extra washer after was done. Was for temp sensor change out. Had an old boss tell me if if ain't broke, leave it alone. I did. No problems.

Placed containers in the racks to check sprayer output. Watched the repair videos on removing the spray arms, upper and lower. Removed the arms and cleaned the spray ports plugged with calcium. Reassembled and ran the washer, after placing containers in the racks to catch the water checking output. Still not enough water, in the upper rack. Watched the video on replacing the pump filter. The filter was extremely plugged with calcium. Installed a new filter plus the upper spray arm. Problem solved. The videos and the illustrated parts breakdown diagrams were a great help. Tip: Pressed a socket (5/16?) over the 4 prongs of the snap-in connector on the upper arm to release the connector.
