Potterton Puma 80 is cutting out

[gregchivs]

I've been having some right grief with my PP 80 and now it's cutting out within about 12 seconds of firing up either the CH or the hot water.
Some of you may remember a few weeks ago I posted re- my leaky valve that was causing an electrc trip. Well that was replaced, but I noticed that the hot water pressure wasn't too good after my plumber left. In fact, the cold was pretty poor throughout the flat and the hot pressure was so bad that the hot water kept switching off while it was running. Anyway - the main stop cock for the water coming into the flat wasn't on properly so I turned it on and hey presto! - decent pressure into the flat/boiler.
Straight after that adjustment I've been having this problem with the bolier cutting out. Is it related to the greater water pressure? (It's not excessively high) I assume the boiler is cutting because it's overheating but I need to have an idea what might be causing the problem before I decide on a course of action - my last plumber wasn't as good as I'd hoped and I'm not sure whether to insist he comes back or cut my losses and get someone else (recommendations for West Norwood/Dulwich area of London gratefully received!)

Cheers

possibly the pump has failed.

if its cutting out its prob overheating

could well be a partially blocked heat exchanger of a dodgy pump

give AGILE a ring
