Hi Folks, i have a camray 5 combi, boiler fires up nicely, however no hot water. Radiators get hot upstairs but not downstairs. Rads have been bled did not have any air in them. pump is running but gets very hot. Boiler shuts its self off after over heating. Any top tips and handy hints would be very welcome.

probably a stupid answer

It could be, but could you see the pump shaft running when the scew was out? If the water came out at more than a drip, then the shaft seals are duff, and indicates the pump is old, which indicates your system is old, which means it's probably dirty, and if you put a new pump in it might not last long.

take a look at the operating/installation manual, fault finding...it is very good. one of the better boiler manuals ive seen, well written and easy to follow.
