Boiler Problem - Halstead Ace High

[simonwright91]

Hello all

i was wondering if someone could point me in the right direction, my Halstead High ace boiler works fine with hot water, but when the heating trys to come on the fan kicks in and sounds like its fired up and then just cuts out.... and the power light starts flashing, i also on Wednesday put some central heating cleaner in the system so thats not made any difference

thank you

Here is a video

My first thought was flow switch or low system pressure but as the hot water works ok I would check the ch thermister.

hi all its really cold in my house atm its not turning into heating mode at all now just doing what it does in the video...

could some on guide me through how i could get it to work,

im guessing its a stuck pin were it switches over to heating and hot water.

there is no problem at all with the hot water only its not amazingly hot...
