I would be interested to see any photos. Sounds like maybe the machine has suffered some kind of water damage in the past?

I am going to attempt to pull a shot or two tomorrow on my 2002 Classic, Fingers crossed !

Yes in all it’s glory - I have this one and another spotless working one 

This was sold as no water through the group - so blocked solenoid or blocked hole to the solenoid

Got 3 out - Corrosion was where it went through the boiler

It’s looking better already.

It would probably benefit by a long soak in citric acid? That’s what I used on mine, but mine wasn’t a bad as yours. 
If you can persuade the remaining bolt to come out, you are on your way!

I am thinking about fitting a PID on one of my machines, I don’t know which one yet. Could you maybe put a photo up of the PID setup on your other machine please? It’ll give some idea of positioning.
thank you.

Standard @MrShades set up as I have room and slightly lower to accommodate the socket

Benefits I’ve found are the brew temperature set to 93°C means no bitter coffee and as it is using an electronic sensor the fluctuations are smaller - so mine goes between 89°C to 94°C - you also lose the steam stat and use the brew stat - mine is set to 137°C so is cycling around 133°C to 146°C

Amazing how anal you become about the temperatures!

Many thanks for the photo and information on your setup, looks good, I like the cups very much, are they stoneware?

My first attempt today at pulling a shot wasn’t very productive! Next thing on my list is to fit  PID soon!

I noticed the steam output was really powerful! Could this be down to upping the thermostat 155*?

Did you tamp the Limini? I only need to tap the portafilter on the worktop as the grind is so fine

Every different brand of coffee is different in the portafilter

Steam needs to be powerful especially with a Rancilio - start it just above or just in the milk

The Blue cup is Denby - Yellow was from Sainsburys

Hopefully the Limini will be arriving tomorrow. Will try the no tamp method.
 Okay on the steam technique.
