Is this fault happening for heating and hot water?

Although the zone valve is opening it may be missing a cog now and again and not pushing the lever against the micro switch in the actuator.

You say motorised valves so I am presuming you have 2 or more. So it would be good to know if its happening on all the valves or just one particular zone valve.
