My digital mixer shower is running too hot or fluctuates from hot to cold

Troubleshooting

Please see below our recommendations for resolving the temperature issue with your digital mixer shower. If none of the suggestions resolve your problem, please book a service repair online. If your shower is still within warranty, please contact our Customer Service team by using the contact us form.

Please ensure your hot water supply is between 55-65 °C.


If this has not resolved the issue:

On your controller, access the "Function Menu" on your controller and adjust the "Maximum Showering Water Temperature" to ensure the temperature is set correctly.

Please refer to your Wireless Controller User Guide for more information.


If this has not resolved the issue:

Unscrew the showerhead from the hose/arm.
Run the shower without it attached, ensuring it is over a water catchment area.

Please read our helpful guide on how to remove a showerhead.


If the temperature has stabilised:

The showerhead may be blocked. We recommend that you descale the showerhead with a plastic kettle descaling solution.

Poor shower performance can be avoided by regular cleaning of the showerhead.

Please read our helpful guide on how to clean your showerhead.


If this has not resolved the issue:

*If applicable* Unscrew the hose and run the shower without it attached (only if over a water catchment area).

Please read our helpful guide on how to remove a hose.


If the temperature has stabilised:

Your shower hose may be kinked, or the lining may have collapsed. We would recommend replacing your shower hose. View our range of shower hoses.


If the issue is not with the hose or showerhead:

This shower contains filters and non-return valves, which we would recommend being checked by a qualified tradesperson.


If none of the above solves the issue,
