Hi Folks,

I'm relatively new to the forum and am loving the depth of knowledge available here. Hopeing to avail of your collective wisdom and maybe even contribute eventually.

As of last weekend, I am the proud owner of a new-to-me Vivaldi S1, 2005 vintage.

When I got it home I pulled the panels to give it a once-over and clean down, and then things got a little out of hand....

I'm looking for a little help rebuilding it.

I sourced the La Spaziale documents but they leave a lot to the imagination, so I wondered if anyone has a rebuild post that includes some photos, in particular of the wiring.

Thanks for the help
James

Some updates/progress:

- descaled the group boiler
- replaced the group boiler gasket
- repainted the floor of base

Try on the S1 Cafe website for rebuild info.

Great advice - I wasn't aware of this. Thanks!

Is there anything specific you want a photo of? I'll be tearing apart a Vivaldi some time around the end of this week.

Thanks - yes, I came across this manual too. It's pretty detailed, and should be a good help.

If you happen to have a machine open, a few photos would be very helpful. I hadn't intended to do a full tear-down so wasn't careful enough to photograph the routing for all of the wiring and water hoses.

In terms of general advice - It seems that this machine has been serviced before - judging by the color of the brass, it has replacement thermostats and maybe over-pressure-valves. Are there any parts that are worth replacing preventatively, just as part of periodic maintenance? While I have it apart..

Thanks for the help!



PS: I guess I should also 'fess up... that's a cup of tea in the background of my teardown photo above.

A little update:

I was too impatient to wait for an OEM gasket to arrive by mail so I bought some gasket material from the local Grainger and cut one.
It's a cellulose nitrile 1/16 inch rated to 400F and 1000psi. Has anyone gone this route - does this sound/look about right? Any advice?





I've managed to rebuild most of the hardware, but none of the electronics yet.

A few details I couldn't find anywhere:
- should i use PTFE tape on the water joints? Or just tighten them "dry"
- is there a torque spec for the boiler head bolts? I used 10 Nm, but that was based on nothing other than what "felt" right...





Any thoughts/comments much appreciated.

Cheers,
James
