The plastic rings have broken off 3 leads on the hydraulic module and I'm looking for a service manual for the replacement of this piece.
Contact Rancilio directly. The excelsius is their highest end of machines and I'm sure they're on top of keeping the reputation up on them
I'm not sure what module you are referring to. Here is a parts diagram: http://download.partstown.com/is-bin/intershop.static/WFS/Reedy-PartsTown-Site/-/en_US/manuals/RA-Classe9USBXcelsius_pm.pdf
Give me a part number for what you are referring to.
Getting inside one of these is not for the inexperienced tech with Rancillo. Everything is tight and some things are a bit delicate. Basically you would have to start with disconnecting the power, drain, and water, draining the boiler, and removing the rear panel and the cup warmer system.just to get access to the interior. Draining the boiler requires a special fitting to set up a siphon and disassembly of the drain pan..
Sometimes it's better to send it to a service company and get a loaner from them as they repair it. Some parts take time to get.
