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


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.

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.


Is there a reset button anywhere?


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

These work on electronic ignition, there is no pilot.
