Changed pcb board on boiler tested ransformer for resistance still no power to boiler, power at spur tested to fuse. once turned on blows fuse on pcb any answers thanks.
unplug everything from pcb, does it blow fuses? No? plug one thing in, does it blow fuses? no? plug another in, does it blow fuses? no? plug another in. Etc. You'll find the culprit in the end.
I would have checked fan by feeding it directly, because the aps ould be responsible for the dead short or the wiring loomb. I would have checked for which external item the short came, but then check the item on it's own, and check the wiring to it and any interuptors like low water pressure sensors overheat sensors aps.
hi. I have less than year ago Worcester Junior 24i boiler, and twice in last week have lost pressure on boiler, don't appear to have visible leak anywhere, or excess water out of P.R. Valve.
Problem seems to occur after heating has gone off, and then HW tap is run , sometimes quite fast. Next thing I know, red alarm light is flashing.
Have to top up the pressure and push red button.....anyone have any ideas??
