Dishwasher shows E7; unit may fill but not wash, or may stop with little activity after filling.

Safety first: Disconnect power at the breaker before accessing the pump or wiring.

• Listen for pump operation: Start a cycle and listen. If you hear filling but no strong spray or motor sound, the circulation pump may not be running.
• Check wiring: Remove the lower kick panel and tilt the dishwasher slightly back. Locate the circulation pump on the sump. Inspect the wiring connector for secure fit and signs of overheating.
• Impeller check: With power off, remove the pump (usually a twist-lock or screw mount). Inspect the impeller for debris and verify it spins freely. If seized or very stiff, replace the pump.
• Electrical test (advanced): Measure resistance of the pump motor windings. An open circuit or short indicates a failed motor.
• Control board: If the pump is good but never receives power, the main PCB may be faulty and should be serviced by a technician.
