The pump keeps running on my Baxi solo 3 pfl 50?

When i switch off the external controls calling for heat the pump on my baxi solo 3 keeps running and the motorised valve stay open i believe the pump shoul run for 8 minutes then switch off. the only way i can shut it down is to turn off the power supply to the boiler its self. help

We have exactly the same problem - the pump continued running. Plumber diagnosed problem with the circuit board. This was replaced but now the new circuit board is cutting out completely. Watchdog featured Potterton boilers - major problem with circuit boards. The Baxi Group supply Baxi and Potterton boilers.

Replae the printed circuit board which has an inbuilt pump run on timer
