BIASI PROBLEM. HW WORKS FINE BUT CH DOES NOT WORK M90F 24S

[nick282]

Hi,

I am having a problem with my BIASI. I get hot water fine, the boiler ignites and there is no trouble there. However, when I turn the central heating on, it goes to fire up and then goes straight off. It will try again but not working.

The red cut out light is not on, but the power light which normally flashes steady, is flashing quite rapidly.

The bar pressure is at 1.5 and the gas valve is properly turned on.

Would appreciate any help as I have a 1 year old and a disabled wife.

Thanks
Nick

I am sorry but I am unable to help with the wife or child.

The boiler fault just possiblty might be a failed diverter valve motor but tbere are so many possibilities and I dont know what your skill level is.

Try searching this forum for instructions on how to check it.

With the boiler all cold and CH selected, how long doies the flame burn for?
