Gaggia Classic - unmodded start brew notes

Some notes on using the Gaggia classic Evo 2023 model .
This is a original un-modded version.

Temp stability is a bit of a problem on this machine. 
You really need a PID of turn it into the Gagginuno.

On a un-modded machine you'll need to temp surf to get a consistent temp at the group head.
1. flush water into the group until the brew light goes off.
2. when the brew light turns back on, wait 10 secs, 
     then turn the steam button on for 6 secs.
3. Turn steam button off. Wait 4 secs.
4. now start the shot.

Pre-infusion
1. leave the brew & the steam button off.
2. Open the steam valve fully for 4 secs, 
3. Turn on the brew button.
4. then close steam valve slowly for 4 secs

This should give about 8 secs pre infusion



I try to aim for 8 sec pre-infusion, 20 sec post (brew)
18g in, 36 g out.
