Profitec Pro 700: Cleaning the Fill Probe

If your boiler is over-filling, or you'd like to perform some routine maintenance on your Pro 700, here's how to clean your fill probe

What you'll need:

- 13mm wrench

- Steel wool or brush


First, you'll need to remove the panels of your machine. Locate the fill probe, and disconnect the wiring from the top. 


Using a 13mm wrench, loosen the top nut portion of the probe connection.


Pull the probe up and out, noting how far it was inserted into the boiler.


Using a steel wool pad or bristle brush, scrub any mineral buildup off. The probe should look something like this.


To reinstall, follow these steps in reverse order. If you have any questions, contact us at
