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
