Biasi Riva Compact HE MK2 32 SM/C

Hi Guys,

Have a Biasi Riva Compact HE MK2 32 SM/C.

Boiler is not igniting for heating or ho water. The operating light is flashing green however when a hot tap or heating is turned on the light keeps flashing green and boiler is not going through ignition sequence.

Any ideas, gas supply is all OK. Pump was changed and air has been bled from system.

Thanks

Does the fan run ?

There first operating light on the left is flashing green. When I reset the boiler I can hear the fan kick in around a second or so and a click noise and the boiler then doesn't go any further.

The left green operation light continues to flash and when hot water tap or heating is turned on the boiler does nothing cannot hear the pump running ether.

Sounds like it could be the pcb try warming it up with a hair dryer for a good 5 - 10 mins with it off

They have a separate ignition board them, it'll probably be that if it won't go through it's ignition stages.

Hi Guys,

I dryed out the pcb and opened the hot tap. Now the error is showing as faulty APS.

I have blown into the APS tube and can hear it click.

Would it be a faulty pcb.

Does the boiler fire when you blow down the tube ?

No it doesn't fire up if I blow down the tube. Its odd because customer said it was working ok before the pump was changed.

I just reset the boiler again and opened up the hot tap and now it's not going through the sequence anymore.
