Dishwasher stops and shows i50; may not circulate water or may stop shortly after starting.

Safety first: Disconnect power at the breaker. Water inside the unit may be hot; allow it to cool.

• Listen for motor operation: Start a cycle and listen. If you hear only clicking and filling but no strong spray noise, the circulation pump may not be running.
• Inspect wiring: Access the bottom of the dishwasher and locate the circulation pump. Check the wiring harness and connectors for burns, corrosion, or loose connections. Reseat connectors firmly.
• Check for obstructions: Remove the filters and inspect the impeller area (if accessible) for broken glass or debris jamming the pump.
• Test motor: With power disconnected, measure resistance across the motor terminals. An open circuit or very low resistance indicates a failed motor.
• Control board check: If the motor tests good but i50 persists, the main control board triac that drives the motor may be faulty and the board will likely need replacement by a qualified technician.
