Profitec Pro 500: Replacing the Temperature Probe

If your machine is heating inconsistently, you might need to change your temperature probe. Here's how:

Tools Needed

- 2.5 mm allen key

- 3 mm allen key

- Adjustable wrench


1) Remove the panels

2) Locate the temperature probe on the right side of the boiler.


3) Follow the wires from the probe and disconnect at the black connector behind the boiler.


4) With your adjustable wrench, unscrew the old temperature probe.



5) Apply a few threads of teflon tape to the new probe and screw it in.

6) Before you put the panels back on, turn your machine on to test the fit.

7) Enjoy.
