Description

This wash motor drives the dishwasher's circulation pump to move water through the spray arms for cleaning. Replacing a worn motor restores water circulation so dishes get rinsed and cleaned properly. What it does

• Turns the circulation pump impeller to circulate wash water through the spray arms
• Restores normal spray pressure when a failing motor causes weak or no spray
• Stops grinding or high-pitched motor noise caused by worn bearings
• Helps resolve intermittent or complete loss of wash function when the motor fails

What's included One wash motor Install notes

• Handle electrical connections carefully; match wire connectors and routing during reassembly
• Inspect gaskets and sump/pump seals during install and replace if damaged to prevent leaks
