Profitec Pro 300: Steam Boiler Temperature Sensor Replacement

Below you will find step by step instructions on replacing the steam boiler temperature sensor in a Profitec Pro 300 espresso machine.

Tools Needed:

• 2.5mm Allen Key
• 17mm Wrench

1. Remove the top panel of your machine.

2. Remove the 2 wires from the temperature sensor.

3. Use a 17mm wrench to remove the sensor, once it's loose you will be able to remove it with your fingers.

4. Install the new sensor - be careful not to over-tighten or the threads can break off the bottom of the sensor. Tighten it finger tight, and then give it just a little more of a turn with the wrench. Reattach the blue wires and put the top panel back on.
