4.2 Compatibility Information
It is essential to verify the compatibility of the GROHE 47010000 thermo-element with your specific Grohmix thermostatic mixer model. Refer to the compatibility chart provided below or consult your mixer's documentation. Using an incompatible part can lead to improper function or damage.

5. Operation
The GROHE 47010000 Thermo-Element operates automatically within your thermostatic mixer to maintain a constant water temperature. Once installed and calibrated, the mixer's temperature handle allows you to select your desired water temperature. The thermo-element continuously monitors the incoming hot and cold water temperatures and adjusts the mixing ratio to deliver water at the set temperature, even if there are fluctuations in the supply pressure or temperature.
This automatic regulation provides a comfortable and safe showering or bathing experience, preventing scalding from sudden hot water surges or discomfort from cold shocks.
6. Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your thermostatic mixer and its thermo-element. While the thermo-element itself is a sealed unit, the surrounding components can benefit from periodic care.
- Cleaning: Clean the visible parts of your thermostatic mixer regularly with a soft cloth and a mild, non-abrasive cleaning agent. Avoid harsh chemicals, abrasive pads, or solvents, as these can damage the finish and seals.
- Limescale Prevention: In hard water areas, limescale buildup can affect the performance of the mixer. Periodically run the mixer at its hottest setting for a few minutes to help flush out any mineral deposits. If severe limescale is suspected, professional descaling may be required.
- Temperature Calibration Check: Occasionally check if the water temperature matches your desired setting. If significant discrepancies occur, recalibration might be needed (refer to your mixer's specific instructions or consult a professional).
- Professional Inspection: Consider having your plumbing system, including thermostatic mixers, inspected by a qualified professional every few years to identify and address potential issues before they become major problems.
7. Troubleshooting
If you experience issues with your thermostatic mixer, the thermo-element might be a contributing factor. Here are some common problems and potential solutions:
- Inconsistent Water Temperature: If the water temperature fluctuates significantly or does not remain constant, the thermo-element may be faulty or clogged with limescale.
- Water Not Hot Enough/Too Hot: If the mixer cannot achieve the desired hot or cold temperature, the thermo-element might be stuck or damaged. Ensure the hot and cold water supplies are correctly connected and at adequate pressure.
- Difficulty Adjusting Temperature: A stiff or difficult-to-turn temperature handle could indicate internal issues with the cartridge, possibly due to limescale.
- Reduced Flow Rate: While less common for the thermo-element itself, severe limescale buildup within the mixer, potentially affecting the cartridge, can reduce water flow.
Action: For any of these issues, first ensure that the hot and cold water supplies to the mixer are fully open and at sufficient pressure. If problems persist, the thermo-element may need cleaning, descaling, or replacement. It is recommended to consult a qualified plumber for diagnosis and repair.
