Boiler comes on but goes out (flashing light) - Biasi

[wrightyrx7]

Hi all,

Our boiler is a Biasi Garda M90F. 24S

The problem is, when it comes on it works fine. During the time it is on (timer), at some point it must get to the temp it needs to be and goes off.

When the radiators start to cool it tries to fire up again but there is no flame and the green light starts flashing quiet rapidly. Why its doing this it sounds like its actually on. But like i said you cannot see the flames and we do not get hot water and the radiators cool down.

To fix this we switch it so we can turn it OFF/ON manually. Turn it off, then put it back on the timer and it fires up.

Anyone have any ideas?

Thanks in advance
Chris

Get someone competent who can test the thermisters using multimeter.

POWER OFF , BEFORE YOU TEST THEM
