We have a Truma Combi system with Truma Secumotion Regulator and Truma Duocomfort automatic bottle changeover system. We also have two Gaslow LPG cylinders fitted.
We are on an aire in Portugal without hookup and until a few days ago the heating was working fine on gas.
However now it will not work. When switching it on, it thinks for a while (normal), then you can hear a fan start (normal) and then you can hear a "Whump" as the system igintes.
However within a minute the systemfails and the red "Fail" lights.
After this the whole gas system is locked out and I have to press the green purge button on the regulator to get the hob and fridge to work.
This all started happening after we filled up with LPG at a BP station in Vila Real.
We have full gas bottles
The hob and the fridge work so I don't think it's oily residuein the regulator (but could I be wrong?)
Could the last tank of LPG be polluted in some way?
Any ideas gratefully received as it is very cold down here at night and it's no pleasure when the heating's not working!

The fact that the hob works but the heating doesn't makes me think there is something blocking the jet in the boiler........
I am not an expert, merely a user but it does sound as if something is stopping enough gas getting to the boiler to allow it to fire......
I am sure someone will be along with definitive advice, I have no idea how to sort it out (sorry), the only thing I would do is keep on trying in the (probably vain) hope that something will have cleared it......
The Truma Manual shows;
Approximately 30 seconds after the
heater is switched on, the red LED
is lit.;
Cause;
Gas cylinder or quick-closure
valve in the gas line is closed.
Combustion air infeed or exhaust
outlet is sealed.
Remedy;
Check gas supply and open valves.
Inspect openings for contamination (slush, ice, leaves, etc.)
and remove contamination if necessary.
Light a few burners on the hob, then start your boiler, if the flame on the hob lowers as the heater tries to ignite then it could be a problem with your regulator.
Thats what the probelm was with mine a few years ago.
To rule out regulator problems light all your gas rings and the oven one by one, leave them full on and see if each time you light another those already lit loose flame height. Do that while the fridge on gas.
If flame height goes down each time you light another it's probably the regulator on the way out, partially blocked and not able to pass enough gas, Alan.
Gas systems have a device with a probe sitting in the flame. This device shuts the gas to the heater off if the probe becomes cold (i.e. the flame has gone out) so we don't get gassed.
If this is becoming faulty, it could be cutting the gas supply to the flame.
Thanks for all the replies
I would have replied earlier but my laptop battery died last night at theinternet cafe and stupidly I hadn't brought my 2-pin adaptor Doh!
I'll try all the suggestions.
Luckily it's been a lot warmer today - we've been sitting out in shorts and t-shirts. So with a bit of luck we won't have to go to bed at 9:00pm to stop from freezing to death!
Peejay and erneboy are closest in my view. I've had exactly the same issue on THREE occasions with TRUMA regulators, in only 2 years.
First warning was the red FAIL LED coming on, obviously at the most inconvenient time. I then went through the gas hob flame routine... one ok, two made the flames diminish, three made them extinguish.
As we spend much of our time off hook-up, we need a reliable regulator. We have a large 150 litre fridge/freezer. Having that failing can be quite costly.
Our third TRUMA regulator was fitted under warranty, but I vowed to fit a GASLOW regulator next time as it comes with a FIVE year warranty. And that is what I did nearly 2 years ago. No silly green buttons to hold in to get gas flow. It is so simple.
Buy a Gaslow regulator!!

Hi,
We had same with Truma regs 3 failed with same symptoms - removed and replaced with standard cheapo (£4.30 ebay) regualtor came as 37mb but was user ajustable via a round cover so set at 30mb no probs since in two years
Calor depots will supply and adjust if you are not competent/have the tools required
I now carry a spare just in case but at under a fiver its a no brainer
In 40 years of camping/caravaning/motorhome ownership I have only had 3 regulator failures ALL Truma all on this van with new eruro spec kit
