        How to Backflush an Espresso Machine

        • Remove the filter basket from the portafilter and insert a backflush disc. This disc can be a simple filter basket with no holes or a rubber disc that covers the holes of your machine’s filter basket.
        • Add half a tablespoon of backflush cleaner into the backflush disc. Put the portafilter back on and turn the machine’s pump on.
        • After 20 minutes, the pump will go silent due to pressure formation. Once the pump is quiet, turn the pump off.
        • Once turned off, the cleaner will go through a three-way valve and start to empty via the drip tray. Having a container to collect any solvent coming out reduces any extra mess that could occur.
        • On it’s first run the liquid will likely look murky. Repeating the process several times will be required until the liquid runs clear.
        • After using the solvent, backflush the machine again using just water to make sure there’s no backflush cleaner in the valves.
        • The last step would be to remove the handle and turn the machine’s pump on and off a few times to completely rinse out the solvent.
