I cannot get the heating to function on electric, on the control panel the little electric plug symbol is not being displayed. I have checked the fuse and reset the breaker without finding any fault. Does anyone know if the heating element has failed, does that stop the electric symbol from displaying on the control panel?

It is working fine on gas so we are not freezing to death!

    I don't think an element fail is a common fault.

    You seem to be a very experienced MHer so I suspect it is not finger trouble.  However, a bit of a guess.  Have you checked the set priorities? Incidentally are other things working off mains?

    Yup no other electical problems, its a 3010 boiler by the way not a 3210. I think the 230v pump is working which makes me suspect the element but if the 230v pump is working, I remain puzzled why there is no indication of electric being supplied to the boiler.

    I think that you will find that the pump may be 12v

     I think I am getting a false impression of the 230v pump working. In the absence of electricity it will automatically switch to 12v. I am beginning to suspect either a loose connection to the boiler, quite likely with the shaking up of todays roads or the element has gone.

    As far as I'm aware there is no 230v pump only the one 12v unit.  Otherwise you seem to have checked all that I would have looked at so I'm stumped.  I suggest Ctrl/Alt/Del laughing.

    After a visual inspection, I would use a multi meter/ Voltage tester at the boiler to check its supply, then back to the breaker to test that it’s not faulty.

    Just had a look at my Alde books.  There is a 230v pump but it's classed as an accessory so it may or may not be fitted.

    Update - Went to investigate the problem more fully this morning, plugged in the EHU and switched on the Alde heating and low and behold it is working again. The electric plug symbol is showing in the control panel again! Looks like I have an intermittent connection somewhere which is a bummer because it will not be easy to find unless it goes wrong for good. Could also just be sticky relays on the control board after a long lay up, I hope so. Decide to leave well alone and take a fan heater along with us next trip in case it goes again.

    Some while back I had a similar power problem.  Turned out to be a loose connection in the EHU socket or plug - I can't now remember which.  It seems that over time the screws do loosen off.  Worth a quick look wink.

    I followed the advice above disconnected the network plug (red wire) and 12v supply reseated them and some hours later cleaned the connection when it failed again when still away. What seems to have fixed it is cleaning the connection for the 240v heater element (grey cable) and the feed (yellow cable). I also noticed that there was a slight light brown discolouration of the plastic connector case on one pin. It is possible that this could be the cause of a higher resistance than normal, causing the unit to close down the electric feed, hence the intermittent of the fault.
