How to Clean Your Espresso Machine
Espresso machines accumulate coffee oils and scale silently — and the first sign is usually a bitter, dull shot that used to taste great. The cleaning routine is simple: daily wipe-down, weekly backflush (for machines with a 3-way valve), and monthly descaling. Here's the full routine.

Buying advice
Daily: wipe the group and portafilter, purge a quick shot through the group after the last drink. Weekly: backflush with a blind basket and a half-tablet of detergent — run 5-10 cycles until the water runs clear. Monthly (or per hardness): descale per your machine's instructions. The group gasket should be replaced yearly. A clean machine is the difference between cafe shots and bitter disappointment.
FAQ
Why does my espresso taste bitter all of a sudden?
Built-up coffee oils in the group head go rancid and bitter. A weekly backflush usually fixes it.
How do I backflush?
Insert the blind basket, add detergent, and run the brewing cycle 5-10 times — the water pushes through the group and cleans the 3-way valve.
How often should I descale?
Every 1-3 months depending on water hardness — harder water needs it more. Follow your machine's schedule.
What about the portafilter and baskets?
Soak them in hot water with detergent weekly — coffee oils cling to the metal.
How often should I replace the gasket?
Yearly, or when you see leaks around the portafilter during brewing.
