Truma Ultrastore Water Heater Problem

Recommended Posts

Hi, can anyone help.

I have a 2003 Avondale Dart with the Truma Ultrastore heater.

I have just returned from a weekend away and had trouble with the system heating up on electric.

Each time i tried it, after 7 or 8 seconds it would trip out with the red light. I tried turning off fully for 5 minutes as suggested in manual and tried again, but same fault.

I then changed over to gas and all was OK. I have since tried again on electric and i am still getting the fault.

My initial thinking is that it is the heating element that needs replacing - can anybody tell me how i go about checking this definite.

The Truma Ultrastore does not show a red light if it fails on electric, only when using gas.

 

If you try and light the gas heating without removing the outer vent cover it will not light and the red light will show.

I think Avondales have a red neon indicator light at the main electric switch to the heater.

As in the previous posts this sounds more like a gas fault than the electric. if the electric element was faulty it just would not work or the circiut breaker would pop out. as has been said the most common mistake on gas is to forget to lift the outer vent cover. also on the electric its a good idea to fit an extra neon as the ones fitted by the makers are usually woefully small or in a position where they cant be seen easily and this can result in you leaving the electric on by mistake. every van i,ve had has been like that its pure bad design.

Quite a lot of vans have a neon indicator in the mains switch (if fitted) for the water heater, but it does not tell you that the element is actually working, it simply tells you that you have mains power to the switch and it is on.

Hi users, many thanks for the reply.

Just to clarify:

I always remove the cowl cover whether i am using electric or gas, so if I do decide to use gas the cover would be off.

The red led is actually on the thermostat control, it shows green when on and red when in fault condition. After which time the manual says to turn the power off to the heater for min 5 minutes then back on (this gives a trip out switch inside the heater somewhere time to deactivate).

I know the thermostat only controls the temperature of the water when heating the water on Gas, on electric you do not have a choice and it heats to 70C.

 

If i turn my gas to the heater on, within a time period i get hot water.

If i turn the gas off and switch the electric on for the heater i get the red fault led after about 7 or 8 seconds then lots of cold water !

So i know the fault is electric and not gas - but thank you for the posts

 

I did contact Truma, and short of sending the van to one of their service centres I was given the part number for a replacement element - so may spend a little time surfing the net trying to find the best price as they do not seem to be cheap.

I am not familiar with that type of control. ....however the thermistor that protects the heater on 240 will NOT reset in 5 minutes. ...more like 15 or 20 mate. ..try again if i was you. ....Truma might charge you if thats all it is. ........... obviously make sure its got water apologies if its preachin to the converted. .....and for your info on mains its safe to leave the cowl on. .......

Hi Yorkshire_lass, what caravan have you got? We've got a Swift (2013) and the Ultrastore stopped working on electric, but was OK on gas. A trip to the dealer confirmed that the heating element had failed, (out of warranty). New element fitted and all is working fine.

 

Was this ever solved as this is exactly the problem that we are having?

Hope this helps, Mike.

Out on a site now and having problems withe the Truma Ultrastore water heater Rapid 10 ltr. so can't really do anything to correct until home.

Not working on electric and it is causing main RCD switch to trip and the sites 13 amp box to trip at same time.

Is this indicative of the element having failed?

When I get home I could measure resistance of the element does anyone know the reading I should get?

Anyone got a link to a service manual for undertaking element replacement advice on best source of replacement element also welcome.

Thanks
