Hi.
I have a W-Bosch 28i which worked ok until 4pm yesterday.
Then then it stopped firing up when running the hot water. And nothing at
the rads.

I can't see any pilot flame inside.

The only clue is when we discovered the problem I noticed that the water
pressure had
gone well below 1 bar.

Whats the usual cause of such a sudden failure?

Thanks.

Arthur

A leak... Try topping it up as per the instrustions then monitor the
pressure when cold for a while to see if you have a "leak that is a
problem" or one that can be ignored. I wouldn't be concerned about a leak
that only needed the topping up every 6 months or longer.

Is the pressure drop sudden - when did you last check it? When did it last
need adjusting?

We keep the pressure at about 1.5 and it drops slowly most of the time. I
usually notice
when it drops to about 1.3 so I top it up tp 1.5.

Have you topped it up again and re-lit the pilot then?

On my Combi the pilot is put out if the boiler overheats. No pilot - no main
jet. I guess some are also linked to the pressure.

Having topped up the pressure yesterday it hasn't dropped.

I haven't treid to relight the pilot...haven't needed to do it before...and
don't know how anyway.
I switched the combi off for an hour yesterday as well.

Do you mean you switched it off at the mains? If so that could cause
overheating as the pump would not run to take away the heat in the heat
exchanger. Most pumps are wired to a timer circuit that keeps them running
for about 4 minutes after the thermostats cease calling for heat. If you
cut the mains then the pump cannot run and all the heat in the metalwork
goes into the water and can cause overheating.

Have you got the instructions? On reflection there probably isn't a pilot
light.

Instructions are on Worcester Bosch web site:

Is there a reset button anywhere?

tap...water is hot}

Thanks very much, gents.

Should find a reset button on top of the boiler on the left.

These work on electronic ignition, there is no pilot.

You can't - it's got electronic ignition

Any particular reason why ?

I hadn't thought of the reset button at that stage.
