Ariston Genus 27 BFFI

[DP]

Pump runs, pump proving switch operates, water pressure switch is operated
Air pressure switch not operated.
No fan run.
MI is full of useless information.
Any guidance from those familiar with this boiler, will be of great help.

I am beginning to go off these ariston boilers.

Thank you

Dan

So, are you referring to the hot water or the heating; what's the pressure show on the boiler. As you refer to the hot water switch operating, I assume this is the issue, but is the heating working.

Is there power to the fan Dan ?

 

[DP]

Doggit, does not work for heating or hot water. No fan run so no burner

Terry, no power to fan

I’m sure you have checked these Dan, I’m trying to be helpful but as you say the book isn’t great

I took the high voltage board out and traced the components. The area around the 12 volt regulator looks well cooked and does not produce 12 volts. Am tempted to replace that.

I am sorry to say I fitted this boiler in 1999, which has been a pain in the butt since. Have modified the HW EV connection to cold inlet as it was getting fried every 12 months. Since then has been ok. Needed a pimp change, now leaking a little like a senior citizen. The client has accepted a board may be needed, also has resigned to the fact might be new booked time

Big thank you to you and others for the help.
