we have a grohe shower and the water on/heat level etc unit was not working. I have changed the battery and now the unit flashes "01 service".....
any idea how I get this to work?
many thanks

PlumbDr : Hi , if it's a wireless control unit ? The 01 code is usually lost comms with the main power pump unit. Try checking the main unit for power connection plus any contained fuses may have blown. Hope this helps

many thanks
