1. Introduction
This manual provides essential information for the installation, operation, maintenance, and troubleshooting of your Midea Dishwasher Door Switch.

2. Setup and Installation
Safety First: Always disconnect power to the dishwasher at the circuit breaker before attempting any repairs or installations.
- Preparation: Ensure the dishwasher is unplugged or the circuit breaker is off. Gather necessary tools, which may include screwdrivers, pliers, and a multimeter for testing.
- Access the Switch: Depending on your dishwasher model, the door switch may be located in the control panel, behind the inner door panel, or near the door latch mechanism. Refer to your specific dishwasher's service manual for exact location and access instructions.
- Disconnect Wiring: Carefully disconnect the electrical wires connected to the old door switch. Note their positions or take a photo for correct re-connection.
- Remove Old Switch: Unfasten any screws, clips, or tabs holding the old switch in place and remove it.
- Install New Switch: Position the new Midea door switch in the same location as the old one. Secure it with the original fasteners.
- Reconnect Wiring: Reconnect the electrical wires to the new switch, ensuring they are firmly attached to the correct terminals.
- Test and Reassemble: Before fully reassembling the dishwasher, restore power and test the door switch functionality. The dishwasher should not start if the door is open, and should start when the door is securely closed and latched. If functioning correctly, reassemble the dishwasher panels.

3. Operating Instructions
The door switch operates automatically. When the dishwasher door is closed and latched, the switch signals the control board that it is safe to begin or continue operation. If the door is opened during a cycle, the switch will interrupt power to the wash components, pausing or stopping the cycle for safety. Ensure the door is fully closed and latched for proper dishwasher function.
4. Maintenance
The Midea Dishwasher Door Switch is designed for durability and typically requires minimal maintenance. However, regular inspection can help prolong its lifespan and ensure safe operation:
- Keep Clean: Periodically inspect the area around the door latch and switch for food debris, detergent residue, or mineral buildup that could impede its movement. Clean with a soft, damp cloth if necessary.
- Check for Wear: Visually inspect the switch and its components (e.g., spring, plastic housing) for any signs of physical damage, cracks, or excessive wear.
- Ensure Smooth Operation: The door latch mechanism should operate smoothly. If it feels stiff or sticky, it might affect the switch's ability to engage properly.
5. Troubleshooting
If your dishwasher is experiencing issues related to the door switch, consider the following:
| Symptom | Possible Cause | Solution |
|---|---|---|
| Dishwasher will not start | Door not fully latched; faulty door switch | Ensure door is firmly closed. Inspect door latch for obstructions. Test door switch continuity with a multimeter (power off). Replace if faulty. |
| Dishwasher stops mid-cycle | Door latch disengaged; intermittent door switch failure | Check if the door has come ajar. Inspect the door latch and switch for loose connections or damage. Replace switch if it fails intermittently. |
| Error code related to door latch/switch | Faulty door switch or wiring issue | Consult your dishwasher's user manual for specific error code meanings. Inspect wiring for damage. Test and replace the door switch if necessary. |
