Boiler keeps switching on and off!

Adepizza · 14 Dec 2006

Hello,
I have a Ferolli Modena boiler that keeps turning off and firing up again within 1 second, not much fun when I'm in the shower! This applies to both ch and dhw.
Any ideas anyone?
Mnay thanks.

Could be a flame failure problem but knowing Ferollis it's more likely to be a thermistor

Can also be the venturi which falls apart when you as much as look at it!!!

Not the nicest of boilers to work on.
