Use the included plastic handled wire brush to quickly scrub the group head
while water is running through the group to flush out the particles. (This is why
the long handled brush - to keep your hands away from hot water.)
Also, give the dispersion disk a quick scrub.
Reassemble using the other set of screens.
Soak the original set of screens in Cafiza, Joe Glo, or similar detergent,
scrub, rinse, and put away for next time.
The Way Most Mini V2 Users Actually Do It:
As noted above the official LaSpaziale method was developed assuming the machine is
in light commercial use. This is certainly not the target market for the Mini V2. Here is
how most users clean their coffee group (once every 3-4 weeks is enough):
Start with the basic procedure above, though most folks use something like a
Pallo brush rather than the wire brush that came with the machine for the 3
rd
step. Once the clean screens and dispersion disk are back in the machine
perform the following steps.
Using 1/3 tsp Cafiza, Joe Glo, or similar detergent every 2-4 weeks is plenty
for home use. Backflush the S1 Vivaldi II Mini more often with plain water.
Place the backflush disk in the double basket with 1/3 tsp of Cafiza powder.
Press the single cup button. Wait 5-10 seconds.
Press the single cup button again to stop the pump which automatically
engages the 3-way valve.
Perform the above cycle 5 times waiting about 30 seconds between each
cycle.
Then rinse the remaining detergent from the basket and replace the portafilter
with the backflush disk still installed.
Backflush for 5 more cycles to rinse the remaining residue from the group and
3-way valve.
Remove the backflush disk, make shot of espresso and throw it out.
minimize how often a detergent cleaning is required, after every series of shots is
pulled, run a shot with the PF remove. Scrub the screens and around the gasket
with a Pallo brush while the hot water is exiting the group. This will flush most of
the grounds and sediment into the drip tray.
