If you want your morning coffee to taste fresh and rich, maintaining your espresso machine is non-negotiable. Over time, coffee oils and mineral deposits build up inside the machine, leading to bitter tasting shots and poor performance.
1. Backflush Your Machine (Daily/Weekly)
Backflushing removes coffee grounds and oils from the brew head. Use a blind filter basket and a specialized espresso machine cleaner. Run the pump for 5 seconds, let it sit for 10 seconds, and repeat 5 times.
2. Descale Regularly (Every 1-3 Months)
Depending on your water hardness, descaling is crucial. Use a commercial descaling solution (avoid vinegar, as it can damage internal seals). Follow the manufacturer’s instructions to run the solution through the boiler and steam wand.
3. Clean the Steam Wand
Milk residue can clog the wand and breed bacteria. Always purge the wand before and after steaming milk, and wipe it down with a damp cloth immediately.
Pro Tip: Soak the steam wand tip in hot water and a dairy cleaner once a week for a deep clean.
