Pressurstat Adjustment

  1. Unplug the machine and let cool.
  2. Remove all the water from the top basin only. Do not empty the water in the boiler.
  3. Remove the screw under the drip tray with a 1/4 socket driver with a philips screw on the end.
  4. Lay the machine on its side on a towel.
  5. Peel the bottom cover from the back side. You will see a cylinder with a screw in the middle of one end and a tube on the other end. Looks like this. There will also be 2 wires attached on its side. Around the screw, you will see a small imprint of a line with two arrows. On the arrows, you will see a small “+” or “-” sign.
  6. Turn the screw a 1/2 turn toward the minus sign to lower the pressure. Only turn in half unit increments and immediately test the machine by powering on. MAKE SURE THERE IS ENOUGH WATER IN THE SIGHT GLASS BEFORE TESTING. Repeat adjustment as necessary. DO not adjust higher than 1.3 as the maximum of the range.

  6. Disconnect the two wires and you will need two wrenches – one to grip the pressurstat and one to turn the nut on the copper tubing. Teflon tape is not required as this is a compression fitting.
