Description

This arm motor powers the dishwasher spray arm, restoring rotation needed for even cleaning and proper water circulation. Replace a failed motor to stop arm stalling or noisy operation and recover normal wash performance. What it does:

• Spins the spray arm so water sprays across dishes for effective cleaning.
• Works with the wash/circulation assembly to maintain proper water flow.
• Common symptoms: spray arm not rotating, uneven cleaning, motor humming or noisy during the wash cycle.
• Replaces worn or failed arm motor that causes intermittent or no rotation.

What's included: One arm motor. Install notes:

• Disconnect power to the appliance before beginning any work.
• Handle the motor and mounting hardware carefully; wear gloves and eye protection.
• Verify alignment of the motor coupling and spray arm during installation; ensure fasteners are tightened to spec.
• After installation, run a short cycle to check for leaks.
