britony combi boiler problem?

flow switch stuck on, boiler thinks you have a hot water demand so fires up and cos there isnt a tap open it goes round the radiators =) replace hw flow switch, few quid, power off, cold water off, hot tap open pull wiring connector off and unscrew sensor, new one in, tighten, wiring back on, water back on, observe for leaks, power back on.
