Dishes come out dirty; weak or no spray from spray arms; F4E3 wash motor not running error.

Safety First: Disconnect power and shut off water supply before working under the dishwasher.

Steps:

• Listen for motor operation: Start a cycle and listen. If you hear filling but no strong spraying or humming from the motor, the circulation pump may not be running.
• Check for blockages: Remove the lower rack and spray arm. Inspect and clean the sump area, filters, and chopper (if equipped) for broken glass, food, or plastic obstructing the impeller.
• Access the circulation pump: Pull the dishwasher out from the cabinet after disconnecting power, water line, and drain hose. Lay it on its back if needed to access the bottom.
• Inspect wiring and connectors: Verify the harness to the circulation pump motor is secure and not burned or broken.
• Test and replace pump: Use a multimeter to check motor windings for continuity. If open or shorted, or if the motor is seized, replace the circulation pump and motor assembly with the correct Maytag part.

Tip: Always reinstall seals and clamps properly to prevent leaks after pump replacement.
