1. Cleaning the valve: Turn off the water and power supply, and remove the valve with a suitable tool (such as a wrench). Rinse the inside of the valve with clean water to remove dirt or blockage. Reinstall the valve after ensuring that the inside of the valve is completely clean.
2. Check the water source: there is still a problem after cleaning the valve, and check whether the water source pipeline is blocked. You can try to open the water source valve and check whether the water flow is normal. The water flow is normal, so the problem lies in the valve itself.
3. Replace the valve: If the problem still exists after cleaning the valve and checking the water source, the valve needs to be replaced. Contact Four Seasons Muge after-sales service or professional plumber for more help and guidance.
