ok guys after testing central heating, ibleed radiators with air in atic room....the problem seems to happen after using hot water...the hot water get boiling ! and then after turning off the pressure builds and the temp shoot through the roof, if i then turn the central heating on it all starts to cool...but the radiators seem cold at the bottom..is this a flow problem and like you suggested the water pump on its last legs?

Switch the boiler to hot water only & just check after turning off the hot water tap that the burner is actually going out.. The water valve at the bottom of the boiler has a diaphragm with a pin that activates a microswitch on the servo & tells the boiler to ignite... these scale up & seize over the years changed loads on the 282e....
