Profitec Pro 300 Temperature Probe Cleaning

If your machine is overheating, or failing to hat properly, there may be some scale buildup on the probe (Difficulty ☕)

Tools needed:

• 2.5mm allen key
• 3mm allen key
• 17mm wrench
• Scotch-Brite scouring pad 
• Cafiza cleaning solution
• Teflon tape
• Part if needed: Pro 300 Temperature Probe

Before testing, please drain your machine, unplug it from the outlet and allow it to completely cool and depressurize. 
Then you will remove the panels of your machine.

1) Locate the temperature probe on top of the brew boiler, and disconnect the wire.




2) Make note of the orientation of the wires on the safety switch in the center of the boiler, and using a 17mm crescent wrench, loosen the safety switch and then use your fingers to unscrew it the rest of the way. This will allow for a bit more room to remove the temperature sensor.

3) Use the 14mm wrench to remove the temperature probe by twisting counterclockwise.



4) Remove the temperature probe from the machine and inspect for buildup or scale.

5) Clean the probe (We recommend using Scotch-Brite scouring pads and a mixture of Cafiza and hot water) and then wrap the threads with teflon tape to create a tighter seal. 

6) Reinstall the probe, reconnect the wiring and test. We recommend leaving the top panel off of your machine to make sure that there are no leaks while testing.
