Too many fix ups to list so I will mention two interesting items. An old La Riviera came in with no heat. Found the pressure stat was mechanically jammed and easily got it heating up - only to find the piston seals were so worn that they would not allow it to build pressure. As the unit is quite old, I had track down a set of o rings... Once in hand I had not much trouble replacing them. This is a spring loaded lever and using a clamp is essential in getting the piston back in. All back together & a very nice home espresso maker.
Also I had a mysterious leak on an Expobar. Thought it might have been a seal or the tube that sends over pressure to the drip tray (redirected the over pressure to the water tank). After much searching, I found a faulty gasket in the Ulka pump was the culprit. Additionally the vac valve was scaled and leaky as well.
