Dishwasher runs for an unusually long time or never seems to finish.

Safety: Disconnect power before testing heater or sensors.

• Use hot water: Run hot water at the sink before starting the dishwasher to reduce heat-up time.
• Check heater operation: Open the door near the end of the wash; water should be hot and steamy. Test heater continuity and replace if failed.
• Clean turbidity sensor (if equipped): The sensor is usually in the sump. Remove and clean any film or debris from the lens.
• Reset control: Turn off the breaker for a few minutes, then restart a cycle. If long run times persist with no heating, the control or heater circuit may need service.
