Transformer replaced in Controller box gets machine working again
For those interested, I could recommend visiting a separate thread that I started about my problem at Rocket Giotto Premium Plus won't start - Diagnostic help appreciated - Espresso Machines • Home-Barista.com
I describes a series of diagnostics and how I ended up replacing the Transformer in my Controller box and explains the effects that this fault caused.
It also provides a description of the role of the three relays on the controller board and how the earthed water detectors (at water tank and at boiler) are connected to relays which control the completion of the main 240V circuit and the role which the Transformer has in this arrangement.
All the best and thanks for your interest.
