Profitec Pro 300: Removal of the Power or Steam Boiler Switches

Below are photo instructions for removing a Profitec Pro 300 power or steam boiler switch. This is helpful if a switch has become unresponsive or only functions sporadically.

Before doing this we recommend allowing your machine to fully cool off and unplugging the machine.

  • Adjustable wrench
  • Needle-nose Pliers

1) Remove the panels of your Pro 300
