Someone is coming round later to look at the Boilermate 3 to see if it needs some attention and put my mind at rest. I'm not convinced he is an expert on bm's and as I still haven't been able to find an instruction manual for it I thought I'd come back here for some advice.
1) The hot water is scalding and I'd really like it to be turned down (and reduce gas consumption). From my last post it sounds like the store temp can be adjusted but there is a risk of failure if the mixing valve is stuck. Someone else said the temp is factory-set and hence unadjustable. I cant see the mixing valve if it is there, where is it?
2) The thumping sound, which could be a pump cycling on and off every 1-2 seconds. It doesnt always do this - when it isnt making this noise and I turn the hot tap on it usually starts making the noise again. Is this normal? Is replacing a pcb likely to cure it or is it more likely a stuck valve or related to sludge build-up?
3) The radiators came on late one evening last week after the timer had gone off for the night. Is this likely to be a pcb fault on the bm3? What pcb or pcbs are fitted to the bm3?
I took the front cover off the bm3 last night to see what led's were lit. At the time the left-hand green led and orange store led were flashing. A red led was also flashing - is this the fault led? I couldnt see the fault diagnostic button. Thats why I'm annoyed I cant find a manual anywhere for it. There might be nothing wrong and I'm worrying for no reason. Maybe in 1-2 years I'll fit a combi boiler but for now I want the bm3 and suprima 30 to work and not worry.
Thanks again and sorry for trawling over any old ground.
