Combi boiler failing to light: pressure: 0 bar

organistmatt · 22 Aug 2006

Hi all: I'd be really appreciative if someone could give me some advice here.

I've got a Worcester 24i combi boiler which last night failed to light for hot water. However, this morning - having expected a cold shower - it produced hot water!

The thing that worries me is that the pressure is reading 0 bar, even though today it is working normally.

About a month ago it discharged a largeish amount of water which worried me but I thought that this might have been due to some overflow valve. It has not done this since.

Any ideas?

Cheers,

Clearly the system pressure needs restoring to 1 bar. See the FAQ topic for details. Check that it isn't discharging water again when repressurised.

There's no pressure switch though, so low P wouldn't have stopped it working before, so something else is wrong.

Overheating due to lack of water in the primary part of heat exchanger? I thought it best to eliminate the system pressure issue first anyway.

Nope don't think so, as the over heat button hasn't come up!

It might have noticed lack of flow of water - and not overheated, just not worked. But there seems to be enough water for it to go now.

Anyway, fillerup and see how she goes.
