Hello,
I'm new to the forum. I would like to ask for advice from more experienced individuals on how to dewater Italian boilers. I have a Hajdu boiler that I've done this with twice without any issues. Now, a friend has asked me to clean his boiler. However, when I looked under the cover at the bottom, I noticed there are no screws securing the motherboard. The thermostat is held in place by a large nut, which I hesitated to unscrew. I didn't see any other options available.
Thank you in advance!
