Beaten up S1 - version?

Post by Aran » Sat May 13, 2017 10:14 am

Great forum all, spent most of last night reading - whoever said sleeping like a baby never had kids.

Just bought a beaten up S1 in the UK for 128 USD, needs a lot of work, not to mention PFs and likely much much more. I'm hoping pump & motor are functioning, hell I hope it has functioning boilers, you can't even see a the pressure gauge in the photo so possible I bought some external parts....

Also picked up a Super Jolly (think ex-Starbucks) for 94 bucks, looks heavily used but from what I read these are the Toyota Landcruisers of the grinder world, let's hope so.

I'm keen to start planning my refurb but noticed the badge is LaSpaziale not Vivaldi or other, pardon my ignorance but I only found reference of this for prototypes - figure this is European badging - anyone of you kind folks shed any light here?

It seems like a swivel arm with flush tip not a pivot arm BUT the S1 logo is decal not embossed so it sure ain't recent. Just hoping it isn't a hacked up shell...

thanks in advance!,

Wow. Have you got a project and a half on your hands!

I usually go by the type of gauge and whether the label on the LEDs is in 1C or 5C increments to tell what model it is, but yours has neither. The first S1 Vivaldi generation imported to the US was a dual boiler design that had a single round gauge just for the steam boiler. However, I can tell by looking in the parts manual that there was an earlier single boiler model where the group boiler was also used for steam and hot water. I think the model may have been called the Ricambi. Have you checked to see how many boilers you have?

If you only see one boiler check out the Part Guide on page 29 to see if your boiler attachments look like this:

The beast just arrived. So it is a plumbed double boiler version:

From 2003, model S1. Just that:

Exterior is beat up; both side panels broken, cup holder screen has been bent. Even the plug is destroyed beyond repair - whole thing looks like it's been run over.

Interior is dirty but that's par for the course, nothing obviously damaged at first glance. I see some PTFE so it's been worked on at least once.

Next steps:
Full examination
testing if appropriate
Disassemble
Descale & clean
Parts order
Reassemble
Test
Double espresso(feels a long way out at this stage!)

Initial testing was pretty positive.

- Auto-fill works, quite noisy but pulls water & appears to stop correctly.
- Group boiler heats up, lights indicating temps
- Steam boiler also heats up
- Water and steam work
- Buttons work
- Water out of group (volume seems large)

No dripping, other than the drain valve.

Other than general maintenance (gaskets, descaling etc..) I'm planning to:
- add a dual pressure boiler gauge
- add start-up timer
- drill out the drain hole at the front of the motor housing

Any other must have (low/medium cost) upgrades?

I'm hesitant to add the new board at this stage.

thanks!

Check out the boiler electrical connections especially on top of the steam boiler. The plastic insulator material tends to get very brittle with age. Also, the bare stranded wire between where it goes into the crimp connectors and where the insulation starts tends to get moisture in it and corrode which eventually leads to failure. I'd check and see if any of those crimp connectors should be replaced.

Also, the part you referred to as the drain valve I think is actually the expansion valve. It is supposed to open when the group boiler exceeds 12 bar as a safety measure, but you mentioned that it is dripping. Given its age you should unscrew it and check out the rubber part inside. It should probably be replaced while you are purchasing other parts. BTW: When it is operating and adjusted correctly it will still drip a few drops each time the group boiler cycles. If you do decide to remove this and change the gasket you will need to readjust it after replacement. You will need a working group pressure gauge for that.
