Mend Bosch W275 Light Off Hot Not

Pilot light flicking on and off when hot water not in use?

I have a Bosch W275 water heater fitted in my mobile home. The pilot light is automatic and fires only when the hot water tap is turned on. My problem is that when the hot tap is turned off the pilot light flicks on and off constantly? Any ideas would be greatly appreciated. Thanks
