Heating and hot water not working on electric -Help (1 Viewer)

[Gail-force]

Hi all, my hot water (and heating) cut out last night whilst on electric ( it works fine on gas) I’ve changed the fuses although they seemed fine, but still no joy all other electrics are working ( gotta keep my beer chilled )
I tried reading the manual, but
Any suggestions please?

What model of boiler do you have?
If Truma Combi 4e/6e does the control panel show it should be working on leccy but not? If so, it could be the electric elements have failed.
Did the power trip before you noticed it had stopped working on leccy?

Need to know type of heating Truma or Alde.
As its OK on gas don't panic as it will work better on gas and be cheaper to run.

Given OP's avatar I was going on a late noughties model so probably Truma but ................ Gail-force

Have you checked the breaker on the hook-up post? Running two bits of kit with heating elements in may well have tripped it.

Hi, it’s the truma combi E … the red light is flashing

Oddly enough, all the other power in the van is working fine, fridge, lights, sockets…

Nope, still getting power to all other stuff

I thought the red light flashing was flame failure when on gas.

Resetting the main control panel for the Moho sometimes un-confuses the Tr(a)uma controls - if this doesn't work then it looks like one of your 240v heating elements has failed

Do you have a window above the boiler exhaust outlet? If so, is it fitted with a safety switch to cut boiler operation if it is open?

Other issue may be your leisure battery is failing. Have you got a multimeter you can put over the battery terminals and check the voltage (with ehu disconnected).

We've found that as well particularly if it's not been used for a few weeks.

Our Sargent control panel has a "shutdown" function that kills all power (12v ) and turning the Truma panel rotary switch to 0, turning off the water heater and space heater 230v switches, placing in shutdown, waiting a minute or two and then restarting everything has worked for us.

I tried the on and off and that hasn't worked... I'm afraid it's going to be a trip to our local moho garage, he's really good, knows his stuff, and is cheap! Thanks for the help

Did you also check the couple of possibilities in post #11 above?
Might be worth it before heading off to garage.
