6. Maintenance
To maintain the appearance and functionality of your GROHE Grohtherm SmartControl Thermostat, follow these simple cleaning guidelines:
- Regular Cleaning: Clean the chrome surfaces regularly with a soft cloth and a mild, non-abrasive cleaning agent.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, scouring pads, or cleaning agents containing alcohol, ammonia, or phosphoric acid, as these can damage the finish.
- Rinse Thoroughly: After cleaning, rinse the surfaces thoroughly with clean water and dry with a soft cloth to prevent water spots.
7. Troubleshooting
If you encounter issues with your Grohtherm SmartControl Thermostat, consider the following common solutions:
- No Water Flow: Ensure the main water supply is open. Check if the SmartControl buttons are fully pressed and twisted to the desired volume.
- Incorrect Temperature: Verify the temperature dial setting. If the water is too hot or cold, and the dial is at the correct setting, there might be an issue with the hot/cold water supply or the thermostatic cartridge.
- Low Water Pressure: Check for blockages in the shower heads or hand showers. Ensure the water supply valves are fully open.
- Leaking: If leaks occur around the trim plate, ensure all connections are secure and seals are properly seated. If the leak persists, professional assistance may be required.
For persistent issues or complex problems, it is recommended to contact a qualified plumber or GROHE customer support.
