How to Fix / Troubleshooting
Safety first: Disconnect power before removing the inner door panel.
- 1. Observe behavior: Gently press on the door during a cycle. If the machine resumes or pauses, the door switch is likely intermittent.
- 2. Inspect latch and strike: Check for wear or bending. Adjust or replace as needed to ensure firm engagement.
- 3. Check door switch wiring: Access the Haier door switch and verify the connector is tight and wires are not frayed.
- 4. Replace door lock assembly: If the switch tests intermittent with a multimeter, replace the entire door lock assembly.
- 5. Verify leveling: Re-level the dishwasher to prevent door twist that can affect switch engagement.
Warning: Do not bypass the door switch; it is a critical safety device.
