We have a "Whale" space heater in our Elddis motorhome, the control panel is a duo panel in that it operates both the water heater and the space heater. The space heater is working ok but the water heater control appears to have a mind of its own, Its fluctuating between , 1 bar , 2 bars 3 bars , gas and gas and electric. even though its not on EHU. it comes on and goes off on its own. tried resetting it, When its in this mode the touch controls do not work in that they will not switch between functions and cannot be turned off.
