Hi everyone

My Glow worm 18hxi boiler has stopped working. It shows error code F4 lor F1. It's done this before over the last two years and the plumber has changed valves which semi-sorted the problem. This year though it won't even restart after a cooling down period. What should I do? Can anyone help?

You need to wait at least 5 seconds before turning on again.

If the problem persists, you will have to call out a Gassafe registered engineer as F1/F4 faults indicate something wrong with the ignition, which is gas related.

So what does this "plumber" say this time?

I cannot think of any valves which would be likely to cure your problem though.

It's about 9 yrs old and has been serviced every year.

Plumber said that the original valves had perished and he was to replace them with graphite valves? The previous year it was something else, can't remember what. I've not asked him this time as I've rather lost confidence in him I'm afraid.

I'll call a corgi registered engineer out for Monday (we're away this weekend).

It only seems to be when the boiler has heated up, no problems with the hot water only. I switched it off but it would only turn back on after about two hours and when neither the water or heating were on. What a pain!

I did wonder whether it was the fan, as it's the boiler has been making an odd noise recently (husband described it as whales singing).

Thanks for all your advice so far.

That 'graphite valve' is a gasket upgrade required when servicing.

I would not use a corgi registered bod - they are not allowed to work on gas appliances. Use someone on the gassafe register if you cannot get a reccomendation.
