BAXI 105HE Boiler Help

[onlyfools]

Hi everyone
I have a BAXI 105HE Boiler which has stopped heating the hot water when opening the tap, I've had a look and the 50% red light above the fan sign is flashing(when the hot tap is running), the pressure needle says just under 1.
When you turn the tap on you can hear something fire up inside (not being a expert,I don't know what it is). I turned the dial to re-set but still the same.
Any help would be great
Thanks Jane

I would say it is either your Fan or Air Pressure Switch.The noise you hear is most likely just the pump. I'm informed it might also be the PCB.

A job for a RGI' I'm afraid
