Truma combi 6 red light

[paulhelenwilko]

The hot air heating keeps turning off after about 3 mins of blowing hot air. There is a ‘slight rumbling’ noise like a gas flame struggling in a breeze and the red light comes on. If I power off and wait for red light to go off I can turn heating back on and lasts 3 mins again.

water hasn’t dumped and gas ok (fridge and hob work).

any ideas ?

Are you on mains or leisure if leisure is battery low ..?

 

[The laird]

Paul start the engine give it a few mins and try again if on 12 v

 

[paulhelenwilko]

Not on mains, behind leisure centre at Stratford. (Well the Moho is, we are now in spoons !) I wondered if it maybe voltage so ran the engine with the heating on and same happened.

Paul leave the heating off for ten mins run the engine then try the heating
Sorry I can’t come to help as gin and bitter lemons are a calling and consumed

Back in 2015, I had red light problems that were sorted by Truma, who identified an issue with the van manufacturer having installed the wiring loom in close proximity to a hot air duct. They replaced and rerouted the wiring loom.

Paul, if you check what model you have, I may have some parts to help you out.

 

[The laird]

Hope you guys are not too chilled .bleeding cold night and morning here paul

 

[paulhelenwilko]

Yes it was blooming cold. Still have same problems. Suspect gas, will refill lpg on way home and test again.

Could try:
Press and hold the red reset button on the boiler.
When the fault occurs again you should get flashing lights on the boiler. Count long and short flashes then use this chart to diagnose the problem.

 

[paulhelenwilko]

Dooh !

Well lesson learnt, after a freezing night and morning on Stratford Leisure centre car park and demonstrating to the world wide web via this forum my own stupidity, I filled up the LPG and the heating works now !

In my defence we both thought we had nearly a full bottle left after Hereford and the stove and fridge still carried on working while we were at Stratford. Is the truma more sensitive to the gas being low ?

Shout out to Stratford on avon council for providing 9 Moho bays and allowing overnighting !

Well when my truma 4e runs out of water sounds like your description. Check for trapped/bent pipes, or even a blockage to the heater.

 

[RoaminRog]

Alls well that ends well!
Glad to hear you’re warm and toasty again!

Yes that was it.

 

[jagmanx]

Yes that was it.

Yes ..."Brain regulator" at fault ! " Maybe caused by this ? "

Where is that? I thought you could not at the sports centre anymore. I did find a place near a cycle way and old railway you could as it doesn’t say you can’t and it’s locked in overnight.
