Evening funsters
We’ve come away in the van for s couple of nights and just come to switch the oven on and there’s no gas.
I have two Alugas cylinders which are both full and both valves open.
The Duomotion is in usual place and I’ve bled through using the green button on the secumotion. Everything that I’d normally do.
I’ve even checked the gas shut off valves inside and all 3 are open.
I’ve checked the oven, job and external gas bbq outlet and no gas is coming out of any.
Has anyone ever experienced the gas pipe gummed up or the Truma Duo/secumotion blocked?
 
We came across a similar situation recently.
Solution (Well it was for us.)
Turn bottles off. Release pressure from pipe to regulator.
Tighten same pipe. (V. Important!!!)
Turn gas bottle on.
Press Securemotion button.
Count to ten.
Go inside (or have glamorous assistant try to turn hob on)
 
Our van has 2 green buttons on the crash protection system, 1 on the pig tail and the other by the pressure regulator if yours is the same have you checked both?

Also as previously said check gas rings are OK, if so it may be the thermocouple in the oven is faulty

Hi
Thanks for your replies.
I’ve tried each hob burner, the oven, the external gas bbq and the fridge and non are working.
Fortunately we’ve got electric otherwise we’d be leaving early.

I’ve tried the buttons to bleed through.
There’s three cut off valves under the sink - all are in the on position.

Unfortunately, non of my spanners I have with me fit the hose connections, so it looks like we’ll have to wait until we get home.
There’s obviously a blockage between the cylinder to appliances and as Emmit has mentioned, it may be at the regulator.
 
Just replied to a similar thread but no response

Have you opened the window above the external flu ?
If so this cuts off the gas (possibly) and the cure is to close the window. There is a little switch (or there might be) at the bottom of the window in the black seal which needs to make contact otherwise the gas goes into your motorhome.

I'm not saying there's a blockage, well, not in the ordinary sense.

It could be that the pressure from the bottle is too powerful to allow the button you press on the securemotion to allow it to operate. Releasing that pressure by turning off the bottle and slightly undoing the pipe and then retightening it worked for me.
If you're within sight of someone in a van, ask them if they've got an adjustable spanner.
 
Undo the pipe that exits the valve, then gently turn on bottle ect and see if you have gas leaving the valve. If not loosen pipe from bottle to valve and see if you have gas there. Just take time and be methodical.
 
Sounds like a Truma regulator issue. Rather like our problem.

No gas, full bottle!

Well we're on our first outing since wintering in Spain. We filled up with GLP in France in March but haven't used the gas at all until today. We tried to light the gas but although the bottle is full, we get no gas anywhere. We first tried the BBQ point, the. The gas cooker and finally the...

Took a new Cavagna regulator to sort it. That was our third Truma regulator that's failed.
Hope you get it sorted.

I got so much help and advice on this site that I got it sorted eventually. The offers of help were brilliant and I'm sure that you'll get the help you need.
 
Are you level?
Just asking as mine wouldn't reset a few months back. I was on a slight slope, moved, reset fine.
 
Hi all
Thanks very much everyone for your replies.
We’ve not had any windows open - just the roof vents/Heki’s.
We’re level - using ramps (according to spirit level bubble anyway).
We’ve bought some microwave meals for tonight so can manage until we get home.
I asked the warden if he had an adjustable spanner but he didn’t have one. Not to worry as I have one at home.
If anything, it’s made me question what tools I carry in the motorhome. I’ve a socket set but doubt I’d need it but always think if I take it out, I’ll then need it.
I’ll undo the hose when I get back and will see if that works.
I shall keep you posted.

Interesting about Truma regulators - I had this replaced when I had the Alugas installed as they said it had failed.
I have emailed Autogas2000 who installed the refillable cylinders as I’ve noticed a blue corrosion around the brass head fitting which was not there a month ago so wondering if that’s part of the issue.
 
Chris at Autogas 2000 is really helpful. He arranged to send me a replacement Cavagna regulator by return post as I'm stuck in France. He really knows his stuff and will give good advice. Please keep us posted. I'm really interested in the cause of your problem.

We had the same problem with the blessed Truma regulator, it was more or less brand new and was clogged up with black sludge from one of the gas bottles, I got a new regulator under warranty from the dealer and also fitted a Truma filter that has replaceable (look washable to me!) filters. Everything spot on now.

Regarding tools.... in my opinion you need 4 screw drivers, one large slotted and one electrical tester type slotted, one pozi 2 and one pozi one. A good quality adjustable spanner (Bahco?) that will cope with a 32mm hex head, and a smaller one to cope with 10mm or less hex heads, a socket set ranging from 6mm to 19mm, a set of side cutters, a pair of needle nose pliers and a pair of normal pliers. A range of zip ties also very useful, a tube of superglue and a roll of self amalgamating tape, and last but by no means least, a small can of ptfe or silicone lubrication spray. ( Not WD40, it evaporates too quickly). This from experience of running a succession of ancient cars like Morris Minors, MX5’s and a 40 year old Coleman Popup tent before we grew up, saw the light, and bought a motor home.....

Cheers!

if you're totally familiar and confident with the 'green button' procedure i apologise for this....
however, its important that, once the bottle valve is opened that the green button on the hose is pressed to pressurise it....this should see a small 'shudder' in the hose as it fills with gas...
next, you have to 'prime' the regulator and this means pushing in the little green button and SLOWLY releasing it (take a couple of seconds to do this).
both these steps need to happen in the right sequence to prime the whole system.
i suggest trying it again nice and slowly....

Thanks for this. Unfortunately, I only have the one green button which is part of the regulator. There are no hose buttons.

We're back home now and Chris at Autogas2000 has been superb so far. I'm due to visit them later this week, so will provide an update as to what's happened.
thanks again.
 
of you only have a green button on the regulator, then see my post above...it must be pressed fully home and then released slowly...
good luck.
 
Hi, yes, you’ll note from previous posts that I have done this but to no avail.
Hopefully, I’ll get to the bottom of the issue tomorrow as I’m due to visit Autogas2000 so they can check it all.
I shall keep you all posted.
Thanks again

Do you have an electric gas shut off valve that you may not be aware of. My brother in law discovered he had one and the switch was located under the drivers seat? It took ages to discover and he wasnt aware of the valve.
It had been switched off by mistake.
 
Not that I’m aware of or according to the owners manual. I do have the secumotion valve fit which cuts the gas off in case of an accident but it’s a sealed unit and will find out tomorrow if that’s the issue.
 
the Secumotion valve is the green button on the regulator....
normally accompanied by green buttons on regulator hose....

Yes but you can’t open it up to see if it’s blocked inside with oily residue plus it’s not electric

True! I've got a collection of three, shiny, expensive, failed Truma regulators. Find it hard to believe they're blocked as Autogas2000 assured me the Alugas bottle has a filter and I've also got a Truma filter in-line which is pristine. So I believe there's something more fundamentally wrong.

Good evening everyone, today I visited Autogas2000 and they stripped the system down and tested everything to eliminate faults.
It turned out to be the Truma regulator.
At first, they thought it was the Duomotion (cylinder selector) so connected a Cavagna replacement but after testing, it turned out to be the regulator. So disconnected the Cavagna and refit the Truma Duomotion.
I bought the Cavagna cylinder selector as a back up and also bought a spare Truma regulator to now back up the newly replaced one.

The date on the faulty regulator was 08 so it must have been the original installed at factory.
Anyway, I now have gas so I’ve no excuse to endure one of the wife’s home from home cooking experiments. Unfortunately!

Thank you for everyone’s contributions.

So pleased that you are sorted.
Nothing worse than a problem that affects your mh fun.
I too have had a failed truma regulator and now carry a spare but WHEN this one fails i will fit a filter and a different make.
 
I carry a screw on regulator with a BBQ point connector, so if I have a problem I can feed gas straight from the bottle into the BBQ point
