Many thanks for your comments. The cylinders are both turned on. The fridge if off and it's a Rapido 665F with Alde heating.

does the fridge run on gas? if so test that and that would narrow it down more?

agree with all the above, but I would start by checking a gas hob burner.

if not ok, then likely to be the regulator or some other feed issue. remember, it can take a while for the gas to come through if it's been turned off.

if hob ok, then try fridge as above....if this doesn't work I'd be surprised.

if hob and fridge are ok but heating not, then might be an error in the ALDE heating system...as presumably this is where the error is showing?

I have no experience of your type of gas cylinders so cannot comment on the gas situation from the pictures. But I assume you must have a gas hob so, unless I am missing something, that is surely the quickest way to see if you have any gas.

If you have gas, one possibility is a problem I have experienced that I thought might be just worth mentioning. With my Alde heating, when it is first switched on following a long period of not being in use, it tends to fail. This is caused by a sticking fan and evidently it is a common problem. On my system it just indicates that the heating has failed with a red light but does not give any reason. Your display panel might give more information which rules out this possibility - I don't know.

Switching off and starting the heating up again usually clears the problem. It may be no help but it's just a thought.

Sorry Bolero boy just beat me to the gas hob point.

Has the gas manifold in the van which distributes the gas to the various appliances been turned off?

Why not try putting in some gas?

yes, alomgside the simple tests outlined above, it's imperative to confirm there is gas in the tank....a quick fill will give a known base to work from.
