Whirlpool dishwasher spray arms not spinning
The top rack comes out clean while the bottom is dirty, or vice versa. These are the Whirlpool part numbers we hold for the components that cause it, with the number of models each one is listed against.
Before you order anything
- Take the arm off and check the jets for grit with a pin — one blocked jet changes the whole pattern.
- Check that the arm spins freely by hand; stiffness means the hub is worn.
- A clogged filter lowers pressure enough that the arm stalls, so clean it before ordering an arm.

This is a diagnostic starting point built from the parts listed for Whirlpool dishwashers,
not a service manual. Confirm the model plate inside the door before ordering: one character changes the part.
