I have a Baxi Solo boiler. Not sure whether this may have anything to do with it but my instinct is not, I had removed a rad in lounge for decorating and only the other day put it back on.
One confession though is I forgot to open the return. Hot water had always been working ok until I decided to switch the heating on. I turned it on, attempted to bleed rads but could only get water to run after air on the two rads downstairs. Upstairs would bleed but not to the point of getting water out. Rads did heat up tho. Had alot of noise from boiler and pipes etc banging and such. Anyway after this night, nothing seemed to work. Tried bleeding again to no avail. Then realised hot water not working either so turned off heating and tried independently but no good. Turned off boiler and reset, seemed to light ok, water put on override but won't heat it. Previous to me putting rad back on, boiler had occassionally been overheating - prob 4 times or so in last few weeks. Had similar prob a year ago that was sorted by having pcb replaced.
Hope i've not messed it up but just wondered if anyone could suggest anything I can try as it's a pain cos I keep forgetting to switch off immersion and it's cold in the evenings! Thanks
