    we have just had the first habitation check on our Bailey 620 Approach. All's well save for the heating working on gas only. Any idea of why this should hapen and the likely cost of repairing.
    We are going away in the van next week to France and wndered whether it could be repaired there?

    Do you maybe have a switch inside a cupboard or wardrobe that you need to put on? Have you checked to see if 240 is getting to the van?

    Thank you for replying. No, there is no switch in a cupboard and yes, the van is getting 240v.

    Some possible sources of the problem (assuming the controls are all being worked OK):
    • Lack of 240v supply to the boiler
    • Elements have failed (unlikely that both have gone at the same time?)
    • Faulty control board in the boiler
    However, the fact that you are asking the question possibly means that you do not have the tools/skills to make the appropriate checks yourself?

    (This reply sort of assumes that your heating is Truma combi - but you don't actually say which model)

    Was the unit working on 240volts before the habitation check was carried out ???.

    The people who carried out the hab service pointed out (as the only flaw) that the heating wasnt working on mains electric. As we need the van this weekend we needed to collect the van for a trip tomorrow.

    They did however confirm that voltage was getting to the heater and that no fuse had blown.
    We don't know whether the fault was present before the habitation check. We are complete newbies, only bougt the van (used) in July last year and have had only three short trips out last summer. So we just don't know whether it was working properly. It does work on gas only so we are going away and will see of we can get it sorted when we return
    I appreciate all your posts and advice.
    Thanks.
    P.S. It is a Truma Combi.

    IF electricity is getting to the element then it should be working.
    IF the element is broken (as mine was) then you may find the electricity shorts out and there is a big BANG (as mine did). :(:(

    Fortunately, I knew how to reset the internal circuit breakers and the breaker on the supply column, in the middle of the night. Do you?
    IF not, can I suggest that you find out - Gordon

    PS I'm not trying to be awkward or unpleasant, just offering some advice. ;)

    Does your heating run off two knobs on the wall. . One gas and one EHU? If so it is like mine. Even though on EHU you have to switch the GAS knob to the single flame .. it is not using gas .. it represents heat ... Then use the EHU knob as norm .. i.e. hot water, heating or both, etc. However if you are referring to the Truma fire knobs on top of a fire then just ignore my post.

    If you have 240v to the unit then either the switching circuit to the heat element isn't working or the element has gone open circuit.
    The only way to confirm would be to check at the heating element connections for a voltage... If there is power there then the element has gone which could be confirmed by disconnecting the supply and checking the element on the resistance scale with a multimeter...
    Andy.
    PS. . The element will have some overheat protection but that should reset after a short time.. I suppose the above checks would indicate if that was a possible problem..

    Thank you all for the advice. Will get test meter out when we get back. In the meantime will use gas only.
    Movan-it does seem to be the same as yours so will try what you say.

    It could be finger trouble, read the instructions very carefully and try and follow them, not easy.

    Don't worry about it until you get back they are more efficient on gas and a lot cheaper to run on gas.
    Depending on how the heater has been fitted it can be very expensive to replace the element probably not worth the bother.

    Thanks Lenny. It will have to wait. And as you say, it works on gas only.
    I'll post back when I know what the problem was and how, and at what cost, it was sorted.

    Hope you get it sorted. I had an expert .. loosely used term ... look at mine and he didn't know why it not working. Then someone told me about the flame symbol still needed to be on.

    Also, just remembered, I made a similar poat to yours not that long ago. I thought it had broken .. and someone explained that on EHU heating it can take up to 10 minutes to actually start working. I tried again and waited. Sure enough it eventually'clicked' on .. worth trying.

    Let us all know please. That's how we learn.

    Looking for the sunny side of the street
    There's a you tube video by Truma themselves which explains the controls - it's taken me ages to get my head round them for exactly the reason Joy has said....might be worth having a look?

    We had problems with ours -'it turned out one of the elements had gone which has now been fixed. At the time all you could feel was a bit of a draught from the fan coming out of the vents (no heat). Even after the element has been changed we find it's better to start on gas, get the van warm, then switch to elec (if ehu price included).

    Hope you get sorted but have a good trip:)

    We had a similar problem with our Truma. I was getting 240 volts to the main block on the heater, but it was not heating. On the control panel on the actual heater there are two 10A slow delay glass fuses - one at the top and visible and the other at the very bottom and hardly visible. Unless a specialist had told me I would ever of known it was there.

    Cost me 90p for 2 new fuses and everything was tickets boo. So I suggest you might want to locate the 2 fuses and check them if you have a meter or just replace them.

    Who ever did the jab check may not of known about the sneaky little bigger at the bottom.

    Good luck

    As @Debs says ... I too find it better to start on gas and then change to EHU.

    This thread shows that something which could be so simple has been overcomplicated by the makérs.
