Worcester 28 cdi switches on when cold tap turned on?

When I turn on a cold tap or flush the toilet the boiler switches on.It doesn't heat the water but surely this is not right. Does anyone have the same experience with this model or any other combi-boiler. Is there any simple adjustment I can make to resolve this. Thanks

just hearing microswitches

once the flame light on panel isn't lighting then no problem. this was fairly commonplace on the cdi's i worked on.

many thanks for your reply. Only the microswitches seem to switch on. Also I think that they come on when the cold tap is turned off or after toilet cistern has filled,
Cheers
