Do-It-Yourself Stories from Customers like You Runs but will not fill with water   Michael K. • Las Vegas , NV • January 25, 2020

I first installed the inlet pump with no results. I then ordered a Control Switch and Float and Nut. This fixed the problem. Everything comes out so clean. I also replaced the filter which allowed me to clean debris around old filter. It is also easier to replace all these parts with the dishwasher pulled out and tilted on its side. I had to pull mine out to unplug power to the dishwasher. Read more

Dishwasher Wash Pump Impeller Assembly
Genuine Whirlpool part
By: Whirlpool
Part Number: WP902461

Fix weak spray or poor cleaning caused by a cracked impeller. Simple 15-minute repair with basic tools. Restores water circulation and pressure.

Do-It-Yourself Stories from Customers like You Broken "impeller assembly"   Michael P. • Carriere , MS • September 26, 2016

The initial problem was just a simple blockage on the filter screen...until I dropped a screw. So, I had to take the rest of the insides apart to retrieve it. The original impeller would not come off easily, so I tried to pry it off. Naturally, that caused the threaded portion to break. The new impeller went on much more easily than the old one came off, and the dishwasher is back in action. Simple repair; there's really not much to the inside of this thing. Read more

Do-It-Yourself Stories from Customers like You Leaking hose upper spray arm and drain hose replacement   Elizabeth D. • Afton , VA • May 19, 2015

Removed dishwasher to replace spray arm pine--I replaced washer on pipe, too, and would recommend doing this just on principal. Removing dishwasher requires disconnecting power, water, and drain line--tools will vary depending on connections. i replaced drain line because original install was not done correctly--hose too short--You could probably do just this w/o pulling unit. All parts arrived very quickly and fit correctly. Read more
