How to Fix / Troubleshooting
Safety first: Disconnect power before accessing side panels or the base.
- 1. Access pressure switch: Remove the side panel to locate the Haier pressure switch or analog level sensor connected by a small hose.
- 2. Clean hose and chamber: Remove the hose and flush it with warm water. Clean the tub connection point to ensure no grease or debris blocks the air path.
- 3. Check switch operation: For mechanical switches, gently blow into the port and listen for clicks. Use a multimeter to verify contact changes. Replace if not switching correctly.
- 4. Inspect wiring: Ensure the harness to the sensor is secure and undamaged.
- 5. Replace sensor if needed: If cleaning and wiring checks do not resolve F7, install a new water level sensor compatible with your Haier model.
Warning: Incorrect water level can cause leaks or poor washing; do not ignore this fault.
