Biasi boiler prob

[mkb]

Hi all,
My Biasi boiler is playing up.....Pressure is at 2 bars ( providing clock is correct ) . Put heating on..all works fine, water hot etc.,. But switch heat off and can't get any hot water ! basically on 'Hot water only' the boiler wont fire up so have to put heating on to get hot water !! Help REALLY appreciated .

I do have the same Problem with Savio 424A.
I tried to find a Service manual of it, but only Biasi 24S or
Savio GAIA 424S/RS or 428S found.

Any Idea what is wrong?
Last week i`ve had an Service for this Combi-heater.
But no hot water without heating.
May it be, that diaphragma of hot-water side is defect?
many thanks

Sory, if my english language is not so perfect!

Your Savio is virtually the same as the 24S but the 424 manual will be more detailed but the minor differences are not significant to your problem.

Likely to be a diverter valve fault!
