Newbie help with an Alpha cb24x - overheat LED flashing

[mrfluffy]

Hi all,

I have been searching for a solution to my problem, but to no real avail, so am posting hoping someone can help.

I have an Alpha cb24x combi boiler, which for years worked with no problems. Initially when I moved in it was "on show" but about 4 years ago I had the kitchen refurbed and now it lives in an IKEA cupboard.

All has been well until late November when the boiler kept cutting out and showing the flashing red "A" LED.

I would reset the boiler and then it would work for a period of time and then just stop. Sometimes this could be days, other times hours, then mnutes, or even whilst I was in the shower. I had the boiler on for both hot water and heating.

I called my plumber who has serviced the boiler every year since I moved in, but everytime he came round the boiler would be working or he would reset it and then it would work for the time he was there, but then not be working by the time I got home.

On the 2 occasions it has not been on, he has serviced the boiler, left and then within 2 days I'm back at square 1

Could it the cupboard not providing enough ventilation? If so, why has this only just started and not when I put the new cupboard up?


Any help or advice would be welcomed

It's difficult to test components when the boiler is working correctly because they'll be giving the correct readings. I'd very much doubt that the cupboard is causing the fault, what sort of clearances are around the boiler?

Does the boiler make any banging/kettle noises?

It could be many things, it could be an intermittent fault with the gas valve, the temp sensors, the pcb, the overheat stat itself could be faulty. Loads of possibilities.

You need a gsr in to look at your boiler. We cannot and will not give advice on the installation or repair of boilers for your own safety.
