My Worcester boiler will not turn off since the cold spell the only way I can turn it off is by turning the power off. I guess the internal frost control has kicked in but it has now warmed up and the temp is above freezing, does it need reseting ?

I've got the exact same problem... did you manage to figure out what was wrong and get it fixed??

Thanks.

never heard of this fault but it may be possible, it should throw up a fault code though if the sensor was out of range. maybe the how water flow switch is stuck, or perhaps a short circuit on the timer circuit. difficult to tell without seeing it so might be best to have an engineer take a look.
