Below you will find step by step instructions on replacing the steam boiler temperature sensor in a Profitec Pro 300.
- 2.5mm Allen Key
- 17mm Wrench
1. Remove the top panel of your machine, you can do this by following the first step of our Pro 300 Panel Removal Instructions
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 overtighten 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.
