I've replaced the DHW sensor but I've not replaced the CH sensor. I did recieve 2 sensors so do you think I should rplace the 2nd one?
Also I did have the venturi's replaced last summer so could it be a problem with these?
Obviously this is a job for a pro so if the 2nd sensor doesn't work...
Hi,
I'm having exactly the same problem with my ferolli 80e and I was wondering if you managed to resolve the issue?
I have replaced the temp sensor but this hasn't made any difference at all.
