my c/heating pump keeps runing all the time even though it is switched of. It is a baxi solo 3 pfl range boiler which is about 4 years old. Any idea's thanks

Has it always done this since it was installed. If so it could be wired up wrong. If not its probably the pump overrun faulty.

The pump overrun is controlled by the boiler. It keeps the pump running for usally around 5/10 minutes after the boiler switches off to clear heat away from the boiler. Your best bet is get it checked over by an engineer.
