I've got a Potterton Combi 80 boiler. The central heating works fine. But whenever I run the hot water for an extended period (filling kitchen sink for example) When I have finished, the boiler over heats, makes some horrid gugling noises, steam comes out the top and goes into lockout.
I've ckecked the DHW thermistor and it reads 7.3 kOhms at room temp (which is within spec according to the installation manual)
I'm assuming that the pump is ok, cause if it wasn't, wouldn't the central heating not work?
Any other suggestions?
