MY POTTERTON PRIMA 40B WONT IGNITE, I HAVE CHANGED THE THERMOCOUPLE BUT STILL WILL NOT IGNITE. WHEN I GO TO LIGHT THE BOILER THE PILOT LIGHT COMES ON AND I HOLD IT FOR 15 SECS AS PER INSTRUCTION BUT AS I TURN THE IGNITE SWITCH TO LIGHT THE BOILER THE PILOT GOES OUT AND BOILER DOES NOT IGNITE. ANY IDEAS ?
Had same experience today. Fixed it by pressing small brown button (shaped like a plus sign + ) next to temp. control knob on lower righthand side of boiler. Need to remove bottom plastic tray/cover to see it. Don't know what it's for but it did the trick.
