The burner keeps cutting out in the middle of hot water demand with the result of getting freezing cold water half way through the shower and at regular intervals after that. It cuts out when a little yellow light turns on, the symbol relating to this yellow / orange led looks like a fan figure / an exit tube figure....any ideas? Apparently it's something to do with water pressure or gas pressure, all info much appreciated. thank you.

my hot water sometimes comes through other times it doesnt,i can run water through for ages and nothing then other times its right away.
radiators arent a problem they come on instantly and red hot.
but not the hot water however i can have hot water when the radiators are on no worries there.

i have same boiler with similar problem. dont think its anything to do with water or gas pressure. i think it may have something to do with a faulty 'flow switch' or a faulty thermostat in the boiler.

My neon light has gone out on the boiler - How do I fix it as the boiler won't start now?

It happened after turning the main fuses on and off whilst I fitted a new light fitting

Hi There

My aplha boiler CB24 has constant problems i have already had 3 call outs this year with the DHW value being replaced and various other bits because i was randomly getting hot water by putting the heating on.
The new problem is the heating every now and then turns itself on (not switched on my switch). This i understand should only happen when the temperature drops below freezing and i know that is not the case yet. I have found by turning the hot tap on it flicks back off.
Can anyone help, i can't believe i have to call the plumber again so any suggestions would be great.

Hi.
I have the same issue and I found out what this light means: it is a warning light indicating that blocked flue or fan fault, contact your Service Engineer.
