How to Maintain Your Espresso Machine Daily, Weekly & Monthly

If you run a café or pull shots daily, keeping your espresso machine and grinder in top shape isn't optional — it's what separates bitter, channelled shots from balanced, crema-rich espresso. Dirty group heads, clogged steam wands and old coffee oil residue don’t just affect taste; they shorten equipment life. But what exactly needs doing each day, week, and month? And how do you do it without damaging gaskets or pumps?

In short: backflush daily with water, weekly with cleaner, soak portafilter parts weekly, purge steam wands after every use, and descale the boiler monthly. Every number — from flush timing to cleaning powder dosage — is here, drawn from professional daily practice at a high-volume café setup.

Daily Machine Maintenance Routine

Every day, your espresso machine needs a quick but essential cleanup to prevent coffee oils and milk residue from building up. These deposits affect shot quality, hygiene and machine longevity. Here’s the step-by-step routine that should be done at the end of each service:

• Insert a blind filter basket (also called a backflush disc or ) into a double portafilter and lock it into the group head.
• Turn the machine off.
• Hold down the 60ml brew button while powering on the machine. Keep holding until the display shows “cleaning,” then release the button. The machine will run an automatic backflush cycle.
• Fill a 600ml milk pitcher with 300ml cold water. Purge the steam wand into the water to heat-clean it — the water should reach around 60°C.
• Wipe the drip tray clean.

These few steps take under five minutes but prevent major buildup.

Weekly Deep Cleaning Process

Once a week, go deeper. Oils and grime accumulate in the group head, portafilter baskets and internal pathways. This weekly clean removes those deposits using a light espresso machine cleaner .

• Place a backflush disc into the double portafilter and add 2g (about half a short coffee spoon) of espresso machine cleaner. Lock it into the group head.
• Turn the machine off.
• Hold the 60ml brew button during startup until the screen shows “cleaning,” then release. Let the machine complete the cleaning cycle.
• Again, purge the steam wand into 300ml of 60°C water using a steel milk pitcher.
• Use a small coffee spatula to remove the rubber gasket and filter screen from the group head. Also remove the portafilter baskets. Wipe the group head thoroughly with a clean cloth.
• Soak the removed filter baskets and portafilter screens in hot water with 5g (one short spoon) of machine cleaner.
• Clean the gaskets and drip tray again, making sure no cleaner or soaking water touches any rubber or silicone parts.

Note: Never soak any rubber, silicone or gasket components in the cleaning solution — only metal and plastic parts.

Monthly Boiler Maintenance

Your espresso machine’s boiler needs attention once a month to maintain consistent pressure, temperature stability and long-term function. Neglecting this leads to scale buildup and heating inefficiency.

• Open the machine’s drain valve to let any remaining water escape.
• Locate the black switch beneath the electronic display panel. Turn it 180° to the “on” position (fully open). This allows the boiler to release pressure or prepare for maintenance. (Note: The switch is 90° when closed, and 180° when open.)
• After draining or servicing, always turn this switch back to the 90° closed position.

This step ensures safe pressure release and helps avoid unexpected shutdowns or heating element damage.

Grinder Maintenance Essentials

Your grinder affects freshness, dose accuracy and shot quality more than almost anything else. Coffee oils build up inside burrs and the bean chute, leading to off-flavours and inconsistent grinding. Here's how to maintain it:

• Remove the bean hopper and empty any remaining coffee beans into an airtight container. Wash the hopper thoroughly.
• Grind any leftover beans into small amounts of coffee powder to clear the burrs. Use a brush to sweep away all remaining grounds from the burr chamber, dosing chamber and exterior.

This quick routine keeps your grinder running cleanly and your espresso tasting fresh.

Frequently Asked Questions

How often should I backflush my espresso machine with water?

You should backflush your espresso machine with just water daily using a blind filter basket. This means locking a blank portafilter (with no coffee) into the group head and running a backflush cycle — typically activated by holding the 60ml brew button during startup until the display shows 'cleaning.' This removes coffee oils without detergent.

What’s the correct dosage of coffee machine cleaner for weekly cleaning?

For weekly cleaning, add 2g of espresso machine cleaning powder — roughly half a short coffee spoon — into the blind filter basket. For soaking portafilter baskets and screens, use 5g (about one full short spoon) in hot water. Always avoid getting cleaner on rubber gaskets or silicone parts.

Do I need to descale my espresso machine’s boiler monthly?

Not necessarily descale, but you should perform monthly boiler maintenance by opening the drain valve to release water, and toggling the black switch under the display to the 180° 'open' position (then back to 90°). This maintains boiler health and pressure stability, though actual descaling depends on water hardness and usage.

Can I soak the rubber gasket from the group head in cleaner?

No. Never soak any rubber, silicone or gasket parts in the coffee machine cleaning solution. Only soak metal parts like the portafilter basket and filter screen. Rubber components should be wiped clean but kept away from cleaning chemicals.

How do I clean the steam wand properly?

After every use, purge the steam wand into a damp cloth or water. For weekly deep cleaning, purge steam into a 600ml milk pitcher with 300ml of cold water heated to around 60°C. This removes milk residue and prevents blockages or bacterial growth.

How do I maintain my espresso grinder between uses?

Daily, brush out coffee grounds. Weekly, empty the bean hopper, wash it, and grind out remaining beans to clean the burrs. Use a brush to clear the dosing chamber and burr area. This prevents old coffee oil buildup that affects taste and performance.
