Hi Alfredo I changed my pump and my PCB. I had already changed the diverter. Still no joy for me. I'm going to get a pro in or even change the boiler. Andy

Hi Chris Happy New Year. Thanks for your help again. I am very grateful. I'll try what you suggested tomorrow. I've got to go and visit the relatives in a few minutes. Anyway in case the pump fails I'd rather do it on a day when I can buy a replacement quick so I can have a shower. Andy

Hi Tony Thanks for the quick reply. I'm not sure what the impeller is so I don't know if it's still attached. How could I check that? Andy

Hi Guys Thanks a lot for your continuing help. I guess my last post to in reply to Tony wasn't clear. I did do exactly what he suggested and removed the two yellow arrowed connections after turning off the water. (The only reason I delayed was because I was slow to understand what he was...

Hi Baxpoti You've got sharp eyes :!: I checked and the gap is less than 1mm. The manual says 5.5 mm +/- 0.5 Should I readjust the gap or continue to look elsewhere for the problem? The CH worked fine for 6 months or so last year and I am certain that no-one has touched the...

Hi Tony Happy New Year. Thanks for all your help. I am not attempting to try your patience. I did as you said. When I swithched on the CH, the boiler fired at first. The tops of the radiators in all rooms got slightly warm. After a few seconds the boiler switched itself off. The...

Hi Tony Thanks for bearing with me. I turned off the mains supply to boiler. The only way I could see of doing this was to shut off the main stopcock to the house. http://www.7seals.co.uk/assets/images/puma%20100e/CRW_1370-01gred.jpg...

I just noticed there's some carbon on one of the relay switches on the PCB. http://www.7seals.co.uk/assets/images/puma%20100e/CRW_1368g.jpg Is that likely to be the source of the problem? Andy

Thanks ChrisR Thanks, Chris. I'd be barking up the wrong tree for hours then. I tried giving it a quick blast with a lighter. No noticeable effect. The back of the diverter gets hot but the front part, where the wax valve is located, stays cold. Yes, the back of the diverter gets...

Thanks Agile I got it on ebay. The plumb centre were quoting about £120 which seemed a bit steep. Yes, I did that. I did it again today (with the new diverter in) and still no heating. Yes, I waited a good half hour. Yes, all the radiators are are on full. I'm not sure what...

I'm still getting no joy with this thing. I take it that you mean the water pressure swtich (with the yellow arrow) and not the air pressure switch. http://www.7seals.co.uk/assets/images/puma%20100e/CRW_1352-01g2red.jpg ADJ

Thanks very much for your help guys. I got round to replacing the diverter today. It was a bit fiddly at the back as Gasguru had warned. The old diverter does seem sticky now I have it off. Gasguru said: When I finished the hot water works fine still. The radiators are still not...

Hi Tony I looked again. The black knob I unscrewed a bit http://www.7seals.co.uk/assets/images/puma%20100e/IMG_1122g.jpg http://www.7seals.co.uk/assets/images/puma%20100e/IMG_1127g.jpg The axle inside turns only when it's unscrewed like this...

Thanks Gasguru and Tony I checked the taps are tight and unscrewed the motor. It appears to be turning freely. Maybe it's the boiler diverter valve then. Would that be a fairly straight-forward job to replace myself or is it time to call a pro? The boiler was there when I moved into the...

I put the central heating on the other day. I haven't used it since last spring. The HW for the shower etc has worked fine all summer. When I turned the heating on the boiler heats but then turns itself off without the radiators warming. I supspect the pump may have seized up over the...
