biasi 24s no ignition? need help

[justin85]

hi can anyone help with this??

I have a biasi 24s combi boiler 1998, it has been working fine until last yesterday morning now it wont fire up for heating or hot water! when i turn on the hot tap the boiler fires up i can hear the fan turning but there seems to be no spark to ignite it.

The night before it stopped working i had the heating on but some rads were not working so i had to bleed them on some rads the air would start to come out then stop but no water would follow like there was no pressure?

The pressure valve says 20, the green light is on but the manual start or reset button under the red light which is off does nothing when you press it!

anyone have any ideas...???

how do i top up the pressure?

pressure should be 1 /1.2 bar cold

ok pressure is currently at 0 bars, i have no flexible filling loop just a fixed loop with an isolator and another valve with a hexagonal bolt should i turn one of these?

 

[kevplumb]

turn the isolater slowly and watch the gauge
the other may well be a non return valve

success!! i turned the valve until the pressure was 1.5 bar any turned the hot tap on an the boiler fired up!

thanks a lot kev you've really got me out a jam there!!
