Profitec Pro 300: Adjusting the Pressure Stat

Below you will find a video and step by step instructions for adjusting the pressure stat on a Profitec Pro 300 espresso machine. This can be adjusted to allow control over how much steam pressure will build in the steam boiler.

Tools Needed:

• 2.5mm Allen Key
• Flathead Screwdriver

1. Remove the top panel of the machine by removing the 4 screws in the top panel and then lifting it off the machine.

2. The pressure stat is on the right side of the machine. Make small adjustments of 1/4 turn at a time with the flathead screwdriver and allow the machine to fully stabilize before further adjustments, as they are very sensitive. Clockwise will increase pressure, counterclockwise will decrease pressure in the steam boiler.
