Rancilio Silvia Mega-Mod part 2 Disassembly
Avi's Silvia Mega-Mod
My way to a better coffee...
DISCLAIMER - Important!
To start working on Silvia, we need to disassemble its covers and some other parts to reach its internal space and make room for the rework.
Before we begin, make sure to:
1. Get most of the water out of Silvia.
Heat up the boiler, remove the water from the reservoir tank, open the steam valve and run the pump until no water comes out. Then close the steam valve and shut Silvia off.
2. Disconnect Silvia from mains!
I disassembled Silvia in the following order:
Tip: The procedure ahead allows the reach for all the above mods. You might disassemble less according to the mod/s you perform.
6. Unscrew and remove back cover. 3 screws. 2 on the top, parallel to floor and 1 on the bottom of rear face that you’ll find hiding inside a small niche. The 2 top screws need only to be loosened as it slides through an opening in the chassis. The bottom screw is actually connected to the chassis and needs also just to be loosened. This part is removed by sliding it a bit backward and then sliding it towards the top.
Tip: Use right angle small screwdriver for the 2 top screws.
Tip: Use a flashlight to guide you to the bottom screw.
10. Disconnect all terminal connectors from the switches.
Tip: Start from top to bottom.
Take out each switch that you disconnected its connectors to clear room for accessing next switch.
Tip: Mark each connector so you’ll know how to assemble it later on. It is also recommended to use a camera/smartphone and take pictures along the way.
If you got confused, or forgot to mark it, don’t panic, use the wires diagram from Rancilio while assembling.
Tip: In order to gain more space for this task, disconnect other connectors such as from the heat element and from thermostats.
11. Unscrew and remove the front top cover. 6 screws. 4 on the rear side parallel to the floor and accessed through the chassis and 2 connects it to the grouphead. The 2 bottom screws that connect it to the grouphead needs only to be loosened. This part is removed by sliding it toward the front.
Tip: Using a magnetic screwdriver is strongly recommended for the 4 rear screws (but not only).
Tip: General important tip for all external parts:
Since external parts are polished stainless or plastic, you’d like to protect it while storing it during the rework and handling of it. Wrap and place parts that you don’t machine with a protective material such as foam sheet, bubble-air Nylon or soft thick paper.
Attach protective film to parts that needs to be machined.
You’ll thank me for this tip later on when your parts will look brand new as before.
