worcester 30cdi keeps locking out in cold weather

[json61]

Our worcester conventional boiler has a great habit of locking out when it gets cold, it generally needs to be reset at least once a day when it gets cold. Front display shows no gas and no pilot but I suspect this is not the problem as gas supply is fine and using our gas hob has no impact at all. The boiler seems fine until it tries to start, the ignition/pilot light comes on briefly then goes off, shortly after that the diplay shows a problem and the boiler shuts down. Can anyone help? Many thanks.

We have had the same problem, check that your outlet pipe hasn't frozen up.

Thanks will check the pipe.

Does the boiler show any info on what the problem might be? I've just sorted a loose connector on a temperature gauge which gave similar problems.
