How to Fix / Troubleshooting

Safety: Turn off power and water before accessing the bottom of the dishwasher.

Steps:

1. Listen for motor operation: Start a cycle and listen. If you hear only humming or nothing at all during wash, the circulation motor may be seized or not powered.
2. Inspect wiring: With power OFF, access the circulation pump and check the harness connector for secure fit and no corrosion.
3. Check for obstructions: Ensure nothing is jammed in the pump impeller by removing the sump cover and inspecting the inlet.
4. Replace motor: If the motor windings test open or the motor is locked, replace the circulation pump motor assembly.

If a new motor does not clear E7, the main control board is likely defective and should be replaced by a technician.

Dishwasher displays E7; may indicate a circulation pump or motor issue.
