Profitec Pro 500: Replacing the SSR

If your machine is not heating, it may be necessary to replace your solid-state relay. (Difficulty ☕☕☕)

What you'll need:

-2.5mm hex screwdriver

-3mm hex screwdriver

 

To begin you'll need to turn your machine off and remove the panels.

With the panels removed, you can find the relay on the right-hand side of the machine, just on top of the computer (circled in red).

Now that we've located the SSR, you'll need to unscrew it from the bracket using a 2.5mm hex screwdriver. It may be helpful to unplug your heating element temporarily to gain better access.

Once removed, take note of where each wire is plugged into and transfer the wires one at a time onto the new SSR. If you forget, you can always examine the above images for the correct orientation of the electrical connections.

Screw the new SSR into place (and your element if you unplugged it) and plug your machine back in to begin testing. Be sure to fully test the machine's heating function before replacing the panels.

Once you've confirmed the the red LED on the SSR has lit up and heat is back on in your machine, replace the panels and enjoy your coffee!
