Hi all,
I have a 4 year old british gas rd532 boiler. To date no problems at all... Xmas day CH mysteriously went off. I can reignite the boiler manually and all seems well for about 3-5mins.
Once temp rises to 95degC or so the boiler cuts out (normal temp much less than this)... I have narrowed this down to either CH pump (the most likely culprit) or the divertor valve (stop me if you think ive gone wrong so far!!)...
One last check I did was to bleed the rads and then drop the centre impellor screw from the pump to drain/bleed and also check. Seems to have rotation at this end (motor end I think this is?) but I guess the shaft could be broken? Before I go to much further does the above tally with a pump failure/blockage or shaft failure or should I give further consideration to the divertor valve?
Incidentally, since I didnt mention, hot water also hit and miss...
Thanks in advance guys...
