Pro 300: Checking Steam Boiler Heating Connections

Below are photos showing the electrical parts to check for good connection. This is helpful if the steam boiler on a Pro 300 isn't heating up at all.

Before doing this we recommend letting the machine fully cool off and unplugging it. Also, you will need to remove the top panel.

Tools required:

  • 2.5mm allen wrench
  • multimeter(not necessary but helpful)

When checking the switches it is also helpful to use a multimeter on each end of each switch to check for resistance.
