Hi can anyone please help me I have a ocean alpha 240p boiler and when ever i run the hot water tap the boiler fires up and i get hot water for a short while before the boiler stops and i get cold water. the cold water comes through for a short amount of time then the boiler fires up again and i get hot water. this happens thoughout the period of when i have the hot tap open. also the central heating seems to be affected as it will only come on now and again wen its turned on. the system has normal pressure and the front panel is not lighting up with any faults
please can some one help
