4. Operating Instructions
The GROHE Smartcontrol system offers intuitive and precise control over your showering experience.
Temperature Control:
- The central rotary dial controls the water temperature. Turn it clockwise for warmer water and counter-clockwise for cooler water.
- The GROHE SafeStop button is integrated into the temperature dial. To exceed 100°F/38°C, press and hold the SafeStop button while turning the dial further.
- Thanks to GROHE TurboStat, the set temperature will remain constant throughout your shower, even with pressure fluctuations in the water supply.
Water Outlet and Volume Control:
- Each of the three push-buttons controls a specific water outlet (e.g., bath, shower head, hand shower). The symbols on the buttons indicate their function.
- To turn an outlet ON/OFF: Simply push the corresponding button.
- To adjust water volume: Once an outlet is active, turn the corresponding button. Turning it clockwise increases the flow, and counter-clockwise decreases it. The GROHE EcoJoy™ feature allows for a reduced flow rate.
- Multiple Outlets: You can activate and control multiple outlets simultaneously by pushing their respective buttons. Adjust the volume for each independently.

5. Maintenance and Care
To maintain the pristine appearance and optimal functionality of your GROHE Grohtherm Smartcontrol Valve Trim, follow these care instructions:
- Regular Cleaning: Clean the surface regularly with a soft cloth and mild soap or a non-abrasive cleaner specifically designed for bathroom fixtures.
- Avoid Harsh Chemicals: Do not use abrasive sponges, scouring agents, or cleaners containing alcohol, ammonia, hydrochloric acid, or phosphoric acid, as these can damage the finish.
- Rinse Thoroughly: After cleaning, rinse the surface thoroughly with clean water and dry with a soft cloth to prevent water spots.
- Inspect Seals: Periodically check for any signs of leaks around the trim and connections. Address any issues promptly to prevent water damage.
6. Troubleshooting
If you encounter any issues with your GROHE Grohtherm Smartcontrol Valve Trim, consider the following common troubleshooting steps:
- No Water Flow: Ensure the main water supply to your bathroom is turned on. Check if the corresponding push-button for the desired outlet is fully engaged.
- Incorrect Temperature: Verify that the temperature dial is set to your desired temperature. If the water is consistently too hot or cold, the thermostatic cartridge may require calibration or servicing. Refer to the detailed installation guide for calibration instructions or contact a qualified plumber.
- Low Water Pressure/Volume: Check if the volume control on the push-button is turned to maximum. Inspect shower heads or hand showers for mineral buildup that might restrict flow and clean as necessary.
- Leaks: Turn off the water supply immediately. Check all connections for tightness. If leaks persist, professional assistance may be required to inspect internal seals or the SmartBox installation.
For persistent issues or complex problems, it is recommended to consult a qualified plumbing professional or contact GROHE customer support.
