ALPHA BOILER FIRING ON AND OFF

[jimbo1234]

I HAVE A ALPHA BOILER CB28 . WHEN IT FIRST STARTS IT FIRES UP FOR A FEW SECONDS THEN SHUTS OFF THEN ON AGAIN THIS WILL CARRY ON FOR A FEW MINUTES , THEN WILL FINALLY STAY FIRED UP. THIS HAPPENS ON HOT WATER AND CENTRAL HEATING .THE BOILER IS SHUTTING DOWN A FEW TIMES A DAY DUE TO THIS AND NEEDS TO BE RESET. HAS ANYONE ANY
IDEA WHAT IS CAUSING THIS . IT TENDS TO RUN MORE CONSTANT WHEN THE HOT BATH TAP IS RUN FULL BORE
