The GROHE Precision 250 Shower System is designed for intuitive operation, offering precise temperature control and versatile showering options.
4.1 Temperature Control (GROHE TurboStat)

The GROHE SafeStop button is preset to 38°C to prevent scalding. To exceed 38°C, press and hold the SafeStop button while turning the knob. An optional SafeStop Plus allows for an additional limit at 43°C for enhanced safety.
4.2 Flow Control and Diverter (GROHE AquaDimmer)
The AquaDimmer knob controls the water flow and diverts water between the overhead shower and the hand shower. Turn the knob to adjust the water volume. Push or pull the knob to switch between the overhead shower and the hand shower function.

5. Maintenance and Care
Proper care ensures the longevity and optimal performance of your GROHE Precision 250 Shower System. The matte black finish and internal components require specific cleaning methods.
5.1 Cleaning the Finish
- Use only a soft cloth and mild soap or a specialized cleaner for matte finishes.
- Avoid abrasive cleaners, scouring pads, or harsh chemicals (e.g., bleach, ammonia-based cleaners) as these can damage the finish.
- Rinse thoroughly with clean water and dry with a soft cloth to prevent water spots.
5.2 Shower Head Maintenance
- Regularly clean the nozzles of the overhead and hand showers to remove limescale buildup. Many GROHE shower heads feature flexible silicone nozzles that can be wiped clean.
- For stubborn deposits, use a descaling solution specifically designed for shower heads, following the manufacturer's instructions.
5.3 Water Saving Technology
The GROHE Water Saving technology is integrated to reduce water and energy consumption without compromising performance. Regular maintenance helps maintain this efficiency.
6. Troubleshooting
If you encounter issues with your GROHE Precision 250 Shower System, refer to the following common troubleshooting tips:
- Low Water Flow: Check for blockages in the shower heads (limescale) or kinks in the shower hose. Ensure water supply valves are fully open.
- Inconsistent Water Temperature: Verify that the hot and cold water supplies are correctly connected. If the temperature fluctuates, it might indicate an issue with the thermostat cartridge, which may require professional inspection.
- Difficulty Setting Temperature: Ensure the SafeStop button is pressed if attempting to set the temperature above 38°C. If the knob feels stiff or unresponsive, the thermostat cartridge might need servicing.
- Leaks: Check all visible connections for tightness. For concealed leaks, professional assistance is required.
For complex issues or if troubleshooting steps do not resolve the problem, contact a qualified plumber or GROHE customer support.
