Got a Gaggia Classic Coffee in Gold from 1993.  When I try to get water out of the group head, it return backs into the tank.  I have taken the machine apart twice and have checked for clogs in the 3 way valve and the OPV.  I have no idea what else to check.  When I put it back together for the second time I started to see water droplets come from the group head, but at a very slow rate.  I have also attempted descaling the machine.  Anyone have any idea what's going on here?

Clogs are not always easy to find.  If there are no particulate clogs, then perhaps the 3 way is not working.  You may need to check the coil.

Does the machine have great flow with pump/brew on and the steam wand open?

If you disassembled the OPV, how did you reset the pressure for return to the tank?
