Urgent Help Needed For Heating Issue?

Hi All,

I have a modena 80e model boiler and have just attempted to fire up my central heating. The issue I have, is I can get no heating to kick in, and no light indicating that it is even ready.

I have bled all radiators, pressure is at 1 bar, and nothing is happening.

I am still receiving hot water, and when I turn off the hot tap, my central heating standby flashing light appears for a few moments before flashing off again.

Please help if you can! Many many thanks in advance.
