Mira 1663.114 Troubleshooting Guide


If your Atom shower is fluctuating between hot and cold, or if the shower handle is stuck / stiff, or if there is a water flow issue, first, check to make sure that the combi boiler is feeding the shower with hot water. If the shower is receiving a steady flow of hot and cold water and you still experience these problems, it could well be the 1663.114 thermostatic cartridge is broken and replacing it could fix the problem.

Exposed shower valves, such as the Mira Atom and Mira Coda, give shower users a straightforward means to regulate water temperature. Cartridges encapsulated in its bar type housing have a lifespan spanning years. It depletes from continued usage and deteriorates faster when a greater amount of limescale accumulates in the valve or the cartridge.

Frequently Asked Questions: Mira Compatible Thermostatic Cartridge 1663.114


Q: How do I calibrate the thermostatic cartridge?
A: The Mira 1663.114 is already calibrated by the manufacturer. If you prefer the water temperature hotter or colder than 38℃ or 100.4℉, undo the valve’s thermostatic handle and remove. Turn the shower on and wait until the maximum temperature is reached. Use the handle to ¼ turn the cartridge anticlockwise. Measure the temperature using a handheld thermometer. Redo the process until you reach your preferred temperature. To reassemble the handle, make sure the temperature stop (this should be found underneath the handle) is positioned to the left of the stop found on the control shaft. This will prevent the handle from changing the calibration. Affix the cap and recheck the calibration.

Q: Why is there no hot water after replacing the cartridge?
A: Please check water pressure and see if hot water isolation valve is on and nothing is blocking water flow. Also, check if the installation. The cartridge spline must be in the correct position. To do this, swivel the thermostatic handle on to hot. Pop the handle out and partially rotate it. Secure the handle back and check if hot water is flowing.

Q: Leaking shower. Do I have to replace the cartridge?
A: This can be due to deteriorated o-rings and seals, or a cracked cartridge. The worn out parts causing the leak has to be replaced.
