Thanks Gavinda. Had engineer out this morning- pump has stopped working so cabinet is overheating and he reckons air is trapped in the system. Needs to order new pump so no heating for the time being. :(
Thanks Gavinda- that sounds right as I just removed a small nozzle off a pipe from the condenser and loads of brown sludge fell out. There is a bigger waste pipe behind it which all goes into condense unit but I can't seem to remove this- any ideas?
I will get it serviced asap! :oops:
Anyone know a solution to this- boiler is about 5 years old- never had any problems with it but it has started bubbling and gurgling and struggling to fire up.
I would be really grateful if anyone can help!
