I have had my current wireless grohe shower for the past ten years. Recently the main controller stopped working due to an internal fault as a result of accidental damage. I have bought a (nearly new) replacement on ebay but cannot get it to establish a wireless communication with the main pump. I have printed off the internet the operating guide and have followed the instructions but each time "Service 01" is displayed on the display unit, which according to the instructions signifies "no wireless communication". Is there something I am not doing or thinking of? Can anybody help?
