vokera 80 sp combi boiler?

when heating is switched off ,on the boiler and the stat is off no hot water taps are open,boiler fires up by its self . this causes it to over heat and switch its self off.When heating is on everything ok,hot water ok too.

a slow dripping tap will cause this (or a small leak on the dhw anywhere from the boiler to a tap)
