5. Operating Instructions
The GROHE Eurosmart CE faucet is designed for intuitive, touchless operation.
5.1. Automatic Sensor Operation
- The infrared sensor detects hands placed within its detection zone, automatically activating water flow.
- Water flow stops automatically when hands are removed from the sensor's range.
- The Powerbox generates electricity from the water flow, ensuring continuous operation without external power sources. It includes an internal energy-saving unit and additional reserve energy.
5.2. Temperature Adjustment
The faucet features a variably adjustable temperature limiter. This can typically be set during installation or adjusted via a small lever or screw on the side or base of the faucet, depending on the specific model variant. Consult the detailed installation guide for precise adjustment instructions.
5.3. Program Settings (with remote control 36 407)
For advanced functions and settings, use the optional GROHE remote control 36 407. The faucet comes with 7 preset programs, which can be customized:
- Automatic Flushing: Configurable for hygiene purposes.
- Thermal Disinfection: For maintaining water quality.
- Cleaning Mode: Temporarily deactivates the sensor for cleaning the faucet without accidental activation.
- Additional functions and settings can be accessed and modified via the remote control for optimal performance and water conservation.
6. Maintenance
Regular maintenance ensures the longevity and hygienic operation of your faucet.
6.1. Cleaning
- Clean the GROHE StarLight surface with a soft cloth and mild soap. Avoid abrasive cleaners, scouring pads, or solvents, as these can damage the chrome finish.
- Regularly wipe the infrared sensor window to ensure proper detection.
- Activate cleaning mode (if available via remote control) before cleaning to prevent accidental water activation.
6.2. Filter Maintenance
- Periodically check and clean the dirt filter located in the water supply lines to prevent blockages and maintain optimal flow rate (GROHE EcoJoy 6.0 l/min Mousseur).

- The internal energy-saving unit and reserve energy system are designed for long-term reliability.
7. Troubleshooting
If you encounter issues, consult the table below before contacting customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| No water flow | Water supply off; dirt filter clogged; Powerbox not generating power; sensor obstructed. | Check main water supply; clean dirt filter; ensure sufficient water flow for Powerbox; clean sensor window. |
| Intermittent water flow | Low water pressure; sensor interference; Powerbox low on reserve energy. | Check water pressure; remove objects near sensor; ensure regular faucet use to charge Powerbox. |
