Should your control panel become unresponsive, in the first instance please try and reset the shower. The shower is fitted with an RCD to the plug and in the event of a power surge, the shower is designed to trip out. To reset, simply locate this the RCD (as shown below) and press the reset button. Once you have done this you should hear a beep from the control panel which indicates it's now operational. If the panel does not beep or startup after the reset, and you're still within warranty, please contact our customer service team.
