Ok new problem my biasi comb boiler is locking out (red lamp coming on). Ive removed the front panel and it seems to have fixed the pressure guage for some strange reson must of got stuck,as it was showing 0.2 bar instead of 1.5 its gone to about 0.8.. Befor this the boiler was coming on for a while enough to have a hot shower then the next day go out again,but now it just will not light up ,i can here the fan come on and it sparks but just does not light up..Another problem i had yesterday was water was coming out of the back of the realease valve that goes outside when i was trying to put more water in as a result of the pressure gauge showing incorrect pressure. So ive been told by some 1 to empty some water out the rads to release some pressure ive done that that might be why the gauge as gone better-)anyways what do you think i should do now plz plz help or is the next step to call the plumber out?
