Hi, My Alpha boiler CB24, switches off after running for a few minutes. The B light flashes every second. If you turn the power off and on again it starts to run but only for a few minutes. Before this fault intermittantly the hot water would go cold. Is this a PCB fault?????
i went to a boiler and found the same problem fitted a pcb thn it came up with a electrode fault i fitted a new electrode adjusted the possition to 5-6 mm but the problem still ocured phoned up technical but they couldnt give me an answer any one got any ideas?
