alpha combi boiler

[gingerbreadman]

hi there everyone,got a problem with cb24 alpha heating is ok, no h/w
had a corgi/plumber fit new flow switch and he also changed divert valve
still no h/w he says will call back, is there any other parts he will need or am i better off getting a new boiler ? thanks for any info

flow switch is normally the problem.the way to test this is to pull flowswitch of divertor & push in white button on flowswitch and see if it then fires up.if not try both hw/ch thermistors.alphas are good boilers but can be exspensive for parts.invest in a bg 3* contract

The Alpha I had in our previous house regularly had this problem, definitely had a strange liking for flow switches.
