Prepare Your Machine
Turn off and unplug your Breville Barista Express. Remove the portafilter, drip tray, and water filter if present. Rinse removable parts with warm water to loosen coffee oils and residues.
Clean the Portafilter and Filter Baskets
- Place the filter baskets and portafilter in a bowl with warm water and a cleaning tablet, following the tablet’s instructions.
- Let soak for 15-20 minutes to dissolve coffee oils and residues.
- Scrub gently with a soft brush, then rinse thoroughly with clean water.
Clean the Shower Screen and Group Head
Wipe the exterior of the group head with a damp cloth. Use a soft brush or cloth to remove coffee grounds and oils from the shower screen. For a deeper clean, backflush the machine with a cleaning tablet and water, following your machine’s manual.
Descale Your Machine
Use a descaling solution recommended by Breville if you notice mineral buildup or if your water quality is hard. Follow the descaling process outlined in your user manual, ensuring you rinse thoroughly afterward.
Reassemble and Finalize
Reattach all removable parts, fill the water reservoir with fresh water, and run a few brewing cycles without coffee to flush the system. Wipe down the exterior with a clean, damp cloth.
