The truma water heater on my swift bolero will not work on electric when plugged in.  It works on the gas setting giving us heating and hot water but not when plugged in.  The fuses are OK and the control panel doesn't show any faults.

    Sorry you've not received any response yet. Not like our members, they're usually full of really good advice. Not sure I'll be much help as far from technically knowledge is a bit of an understatement 😉. 

    We have two master switches, one says ultrastore and the other something else 😉. I believe that one or both of these (we do not store our motorhome at home so can't check) must be on for ehu to work. Ours live in the back of the wardrobe.  Could you have these too?

    I hope you get it sorted soon.

    there are two fuses on the truma combi.....one under the plastic 'housing' on the top/side and another further down....check the tru a website for a schematic.

    there is also a red recessed reset button on the top near the plastic housing which helps following an overheating situation, this needs a pencil (or similar) to reach in and press it home.

    good luck.

    My Truma was not working on gas, but fine on electric.  After trying everything that Truma could suggest the PCB had to be changed (around £300 ouch).  All working well now.
