Hi Chaps,
the last couple of mornings my relatively new (4 years old)
Worcester Bosch 24 boiler has failed to come on in the early morning.

The thermostat seems to be working ok and the timer unit seems to be
sending signals, but the boiler does not ignite.

At first I thought it might be the fuse to the boiler, so I changed
that and after turning the dial on the front to zero and then back on
again the boiler fires up ok and seems to work correctly all day.

Then last night, it was working fine just before I went to bed but
nothing this morning until I did the dial thing again.


So Have you guys (and gals) come across anything similar?

Is it time for a service? I'm ok with electrcals/electronics tests
but I'm wary of gas appliances, so I'd like to see if there's an
explanation so I don't get ripped off if I have to call a bloke in...

Isn't that a combi boiler?

If so, has it lost pressure - there'll be a pressure gauge on the front
of the boiler - what does it say?

David

no I don't think so, we don't have hot water on demand-- we have a
separate hot tank upstairs,and there's no visible pressure gauge on the
outside.

Its full designation is worcester bosch 19/24 CBi

Having said that, it's behaved fine all day, it just wasn't coming on
first thing in the morning. (Brrrrr)

Maybe its something to do with the system being completely cold at the
start point.

I had a look at the servicing manual, and my thought was perhaps it did
need a service anyway, so I might ring the chap who fitted it for us and
see if he'll come and give it the once over.
