Help again!! Truma heating problem

Me again! Ok so I've got no lpg. But 10 amp hook up. So yesterday I realised I could switch the truma heating to electric and get heat. (Not a bright spark - me that is). Great nice and toasty. So switched it on at 10degrees overnight. Nothing but cold air. Up it to 15, cold air. Up to 20, cold again. Tried again this morning and still only getting cold air through it. Any ideas? Thanks
Ps the circuit breaker switch is on.

Have you tried setting it higher -   25 or even 30 deg ?

Which Truma system do you have? Is it the one with three settings - 500, 1000, 2000W?  If so have you tried different settings?

Does it have a remote sensor?

The more info you can give us, the better we are likely to be able to offer sensible suggestions . . .

If its the trauma with the 500 -1000 - 2000 switch take a look at the ''thermostat'' dial which runs around this switch on mine if its not up full you get no heat, failing that check the main switch for the heating - mine is inconveniently placed at the very back of the wardrobe (there are two one for space heating one for water) but yours might be else where

Profile says 2014 Nuevo so I'm assuming the Truma is a combi so won't have the 500/1000/2000 selection but will have el1 or el2 (900 or 1800).

Yes it has the e1 or e2 setting. I've checked the campsite connection to see if it had tripped. It had although I was still getting power elsewhere. Reset the trip, but still having the same problem. I tried setting the temp higher but that didn't resolve. Found another switch in the cupboard saying heater/water heater so I've turned that on. But no difference. My little electric plug in heater is working. But this only keeps the chill off.

Is there a little 240 volt plug icon on the right of the panel and about two thirds of the way down, immediately below the degrees C icon.

If not, your mains fuse has blown and you are in the merde! It's extremely difficult to get at, assuming you have a spare fuse, which you won't have!

Sorry for the (possible) doom and gloom. I hope this is not your problem . . . i've been there twice.

Have a search. There are several threads in which there are details of how to change the fuse, but if you are big and have long arms (like me) it will be a struggle. (I physically can't do it - I'm just too broad and have arms like a gorilla!  )

Hope it's not the fuse!!

Hi Pad are you getting a fault code on the Truma panel

Hi Gef

The fuse problem I just posted about doesn't show a fault code, so perhaps other problems don't either. If the mains fuse blows the only indication is the disappeared mains plug icon, and no hot air. 

There is a YouTube video instruction on the Truma system. Watch it to the end where there is a reset procedure just in case you've forgotten to do something...

In my Warwick Duo with the EC155 power unit and controls (with the old style rotary knobs), I have found that it is necessary to switch the 12 volt power off at the EC51 as well as turning the Truma heater off at its rotary controls. Wait for 10 seconds, then turn the EC51 back on and then turn the Truma back on (right-hand control).

Yes gromit, there is a two pronged plug thingy on the display panel. I'm small. But you're right I've got no fuses, although I've got spare bulbs!! Do I need to buy a particular fuse and is it in the circuit breaker box? Will watch Paul's video, see if it gives me any clues.

No error code showing

Realised I can't be fuse if two prong thingy is displayed

I am surprised that Paddington has the LCD Truma display as I thought that this came in with the 2015 model year, ah well you live and learn.

Hi Pad is your fridge working
Geof

its not unheard of for the electric heating elements to fail, but rarely two at the same time....general sysmptom would be one bar working when EL2 has been selected...ie less heat...not cool air.

it could be a number of things but in the meantime, can you just swap your gas bottle(s)? what are you doing for cooking if out of gas, using the hotplate?

i assume this is working, and the fridge and ypur sockets? so its localised heater issue.

Yeah the fridge, microwave and sockets are working. I'm using the electric hotplate for cooking. I'm lpg not on gas bottles.

Hi Pad 
I take that the on switch is illuminated in the wardrobe so I can only suggest you try the reset switch in the Truma . You will ñeed to carefully wiggle the draw out switch off mains and remove the cover.  Then too the left slightly there is a pair  of wires you can feel below which is the small reset switch.  You need to hold it in for 5 seconds it's about the size of biro point.  If you have a mirror and torch it would help

Did you get LPG, Paddington? 

Super U in BSM had it earlier today (Monday 30th).

Going down to bourg tomorrow en route to 3 valleys so hopefully get some then and see if I can get heating fired up.

Harrumph. I was working inside my Nuevo today and it was cold so I twiddled the knob and selected electric heating as it was plugged into the mains at home. There was a triangle at the bottom of the screen with an asterisk inside it. This means 'guess what's wrong now' so I scrolled to it and pressed the knob. All the logos disappeared except for the clock and a spanner and the mains plug. I scrolled through and found the 'reset' setting so I thought I'll press that and all will be well. I pressed it and all was not well. All I can get now is a black line across the top, the clock, spanner and mains plug. I pressed the 'return' button, I removed the mains hook up, I switched the PSU  off and on. Bizarrely even when the mains hook up was removed the mains plug logo on the Truma screen still showed.
I think perhaps Thor The Mighty Hammer is called for. That works for Jeremy Clarkson and he knows Stuff. It's a bit strange because the heating worked OK yesterday on exactly the same set up.

Well I've now got lpg so i ve got heating on gas. I will get the heating via electric looked at when I get home

If you have a problem with a Truma heater, email [You must be registered and logged in to see this link.]
I had a fault which was not on their fault FAQs so I sent them a fault description and within an hour I had a response telling me what the fault was and what I should do to fix it. After dismantling the wardrobe and a drawer in order to completely disconnect and remove the boiler to get at the fuse, I removed it and tested it and it was OK. I then removed and replaced a small plug at each end of a cable, and then the heater worked. Another 90 minutes saw the wardrobe and drawer reassembled and the boiler still worked!
Anyway I was very impressed with the speed of response from Truma, and instead of just telling me to summon a Truma field engineer, they told me what I could do to find the fault. They did of course also advise me to contact a Truma engineer but why would I need one of those?
