Daily, Weekly & Monthly Coffee Machine Maintenance

If you pull espresso shots every day, you’ve likely noticed your shots tasting off, your machine running hotter than usual, or your steam wand sputtering. The problem isn’t always the beans—it’s often a dirty machine. Routine cleaning extends your machine’s life, protects flavor quality, and prevents costly repairs.

To keep your espresso machine in top shape, you’ll need to backflush daily, deep-clean weekly, and service the boiler monthly. Each routine targets different parts—portafilters, group heads, steam wands, and internal components like the boiler—and uses specific tools such as backflush discs, cleaning tablets, and fresh water.

Daily Coffee Machine Cleaning Routine

Start each day with a basic backflush and steam wand purge. This removes old coffee oils and milk residue that build up after every shot and steam session.

• Insert a blind filter (backflush disc) into a double portafilter and lock it into the group head.
• Turn the machine off.
• Hold down the 60ml brew button to start the machine; keep holding until the screen shows 'cleaning,' then release. The machine will run an automatic backflush cycle.
• Fill a 600ml milk pitcher with 300ml cold water and use it to purge and clean the steam wand. Heat the water in the wand for roughly 60 seconds.
• Wipe down and clean the drip tray thoroughly.

Weekly Deep Cleaning Process

Once a week, go deeper. This step removes embedded coffee oils and residues that daily flushing won’t fully eliminate, especially around the group head gaskets, filter baskets, and portafilter screens.

• Place a backflush disc in the double portafilter and add 2g of coffee machine cleaning powder (about half a short coffee spoon). Lock it into the group head.
• Turn the machine off.
• Hold the 60ml brew button to power on; keep holding until 'cleaning' appears on the screen, then release. Let the automatic cleaning cycle run.
• Clean the steam wand again: fill a 600ml pitcher with 300ml cold water and flush through the wand for about 60 seconds.
• Remove the portafilter’s filter basket and group head gaskets using a flat tool (like a short spoon). Wipe all parts carefully with a clean cloth.
• Soak the filter baskets and portafilters in hot water mixed with 5g (one short spoon) of cleaning powder.
• Thoroughly clean the gaskets and drip tray once more—but note: never soak any rubber or silicone parts in cleaning solution.

Monthly Boiler Maintenance

Every month, you’ll need to manage your machine’s internal water system. Descaling isn’t always needed monthly unless you use hard water, but clearing the boiler and checking water flow is essential.

• Open the machine’s drain valve to let any old water out.
• Locate the black switch beneath the electronic display. Turn it 180 degrees (slowly adjust if needed) to open the boiler valve. (Closed position: 90°; Open position: 180°.)
• After draining the boiler water, make sure to turn the black switch back to the closed position at 90 degrees.

How to Clean Your Grinder

Your grinder plays a huge role in shot quality. Old coffee oils and grounds trapped inside the burrs and dosing chamber will stale your next shots fast.

• Take out the bean hopper and transfer any remaining beans to an airtight container. Wash the hopper thoroughly.
• Grind any leftover beans into powder to clear the burrs, then sweep away all grounds using a brush.

Frequently Asked Questions

How often should I backflush my espresso machine?

You should backflush your espresso machine daily with just water (using a blind filter) to remove coffee oils. If you use detergents or cleaning tablets, backflush once a week during your deep-clean routine.

What is a backflush disc and why do I need one?

A backflush disc (also called a blind filter) is a solid disk that replaces the coffee basket in your portafilter. It allows water to circulate internally within the group head to clean built-up residue without extracting coffee. It’s essential for daily and weekly cleaning routines.

Can I soak rubber gaskets and silicone parts in cleaning solution?

No—you should never soak any rubber or silicone components (such as gaskets or the drip tray seal) in coffee machine cleaning solution. These materials can degrade. Clean them with a damp cloth instead.

How do I know if my steam wand is clean?

A clean steam wand produces smooth, dry milk with no sputtering or old milk smells. Purge it after every use, and clean it weekly by flushing 300ml of cold water through it for about 60 seconds.

Do I really need to clean the grinder every time I use it?

While you don’t have to disassemble the grinder daily, you should purge old grounds and wipe it down regularly. At minimum, clean the burrs and dosing chamber weekly by grinding unused beans to powder and brushing out all residue.
