la Pavoni Professional, piston stem leak.

DSCF3708This machine was apparently just over a year old.  The piston stem leaked alot and the group got covered in scale.  The stem is pitted as if the grade of the metal is different and something in the water corroded it.  The pressure-stat was also sticking.  Changed mostly all gaskets.  Descaled. fixed leaks, replaced piston stem.  Needed new switch.  Polished brass and copper.  Patina was removed overall except for the base rim.  Steam knob got sanded re-glued and varnished.  Total billed: 2 hours.
