No gas flowing through system

[Chezan]

Hi all,
We had a gaslow system fitted when we bought the van in August we went for half and half as per pics. We used it for 5 days last month without any issue's but yesterday when prepping the van for our full time adventure in Feb we could not get any gas through. The gaslow bottle is on the yellow mark and the UK bottle is full. We have tried the re set button and made sure both bottle taps are fully open and put one of the gas burners on the hob but there is no flow. The green dial normally spins when the gas is flowing but it is not moving? We are assuming even if the gaslow bottle is empty, that the system should automatically use the full bottle. Any suggestions would be appreciated.

You have a green flag pointing to the gaslow bottle, which indicates that there is gas flowing from the gaslow bottle as far as the change over valve. Your problem must be upstream, possibly at the regulator or appliances.

Regulators are what fail most commonly. Diaphragms in them go over time. I carry a spare reg so I can just swap it out in a few minutes and it doesn't spoil my trip!

There shouldn't be any other points that would cause a blockage and if there's a joint that's vibrated loose or a pipe that's damaged you should be able to smell gas and possibly hear a leak.

The only other thing I can think of is a thermocouple failure at the hob itself, but again you should get flow when you turn the gas on and ignite it - the flame just wouldn't stay lit as the gas would auto shut off once you released the knob.

My money's on the reg.

Your manual changeover valve is set to the Gaslow bottle try changing it to the Calor bottle just to make sure.
If no go it's probably the regulator.

Not sure what you are looking at but the Gaslow cylinder is definitely not on the yellow section ?
The black line on the clear plastic cover is your reading mark .
When you say you have tried the reset button, you need to use something like a pencil to push the button right in , you need to hold it pushed in for around 5 seconds.

could try giving the regulator a GENTLE sharp tap whilst someone tries to light the hob.
Sometimes there is an oily residue in the gas which causes the regulator to stick in the shut position when left with the gas on/HP side pressurised and no flow.

Had similar issue years ago with a stuck reg.

Press and hold the little green button on the regulator for about 10 seconds.
