I was lucky enough to find this machine in a shed this week, its been in storage for a decade after being fully restored. My question to everyone, is there an operations manual for this machine or can someone please explain the operation of the two black dials on the base unit ( Right and Middle) thank you in advance.

I am scratching my head on that date. Your machine is just like mine on the inside besides small electrical and valve differences, but it looks like you have a newer Gaggia D90 on your hands. Parts can be sourced for all the assemblies. Unfortunately my Gaggia Tell/LL is out of commission due to a failing rotary switch but I can provide any questions on maintenance and operation.

The groups will be your biggest pain to service, and the number of shots per hour can sometimes be low, but when they function it is among the best out there. I have stated that I can get similar outputs among all my levers but the Gaggia lever is something a little above the others.

Are you able to comment on the valves under the drip tray?

far right one is likely the water inlet, and I can't tell which one is which but the middle and left valves with the black knobs is the gas inlet and hot water valve.

Thank you, this unit doesn't have a gas element ( I did have an old gas/electric machine a few years back or AKA the bomb). I've worked out the water valve, could the two black knobs be for pressure controls or something similar?

I can't tell with the one pic if there is not gas system in place. I'd pop off the drain grille and tray and see what's under in terms of pipes and where they go.

No worries, I'll take off some panels and dig a little deeper.

from left to right:
water inlet - hot water spout - cup tray warmer

to make sure just remove the tray below the groups, most likely you can trace which one goes to which line.
