How to Clean and Maintain an Espresso Machine Daily

Running a busy café or pulling shots at home means your espresso machine works hard. But without regular cleaning, old coffee oils, milk residue, and mineral scale build up—ruining shot quality, clogging group heads, and shortening machine life. If your shots taste off or your steam wand sputters, poor maintenance is likely the cause.

To keep your espresso machine in top condition, clean the group heads and steam wand daily, deep-clean portafilters and filters weekly, descale the boiler monthly, and regularly maintain your grinder. These steps prevent buildup and ensure consistent extractions.

Daily Espresso Machine Cleaning Routine

Every day, your machine needs a quick but essential cleaning to remove coffee oils and milk residue. This prevents blockages and keeps your shots tasting clean. Here’s the step-by-step daily routine:

• Insert the backflush disc (also called a blind filter or rinse disc) into a double portafilter and attach it to the group head.
• Turn the machine off.
• Hold down the 60ml brew button while powering the machine on. Keep holding until the screen shows 'cleaning', then release the button to start the automatic backflush cycle.
• Fill a 600ml latte art pitcher with 300ml cold water, and use it to flush and heat the steam wand (steam at around 60°C).
• Wipe down the drip tray to remove coffee grounds and spills.

Weekly Deep Cleaning Steps

Once a week, go deeper to remove coffee residue and oils that build up on group heads, filters, and internal parts. Skipping this leads to channeling, foul tastes, and equipment wear.

• Place a 2g dose of espresso machine cleaning powder (about half a short coffee spoon) into the backflush disc, then attach the disc to the group head.
• Power off the machine, then hold the 60ml brew key to turn it on. Hold until 'cleaning' appears on screen, then release to begin the cleaning cycle.
• Again, use 300ml cold water in a 600ml pitcher to flush the steam wand (keep water around 60°C).
• Remove the shower screen (the metal filter inside the group head) and the portafilter baskets. Wipe all parts thoroughly with a clean cloth.
• Soak the baskets and portafilter screens in hot water mixed with 5g (about one short spoon) of machine cleaner.
• Clean the rubber gaskets and drip tray again, but do not soak any rubber or silicone parts in the cleaning solution.

Monthly Boiler Descaling and Maintenance

Mineral deposits from water build up in the boiler over time, affecting temperature stability and machine performance. Monthly descaling ensures proper function.

• Open the machine’s drain valve to empty the drip tray and water reservoir.
• Locate the black switch under the electronic display panel. Turn it 180 degrees (fully open) to enable the descaling mode. (Note: the switch is 90 degrees when closed, and 180 degrees when open.)
• After draining the boiler, remember to turn the black switch back to the 90-degree (closed) position.

Grinder Maintenance

Your grinder affects every shot—old coffee oils and stale grounds inside the burrs and hopper lead to off-flavors. Regular cleaning keeps your espresso tasting fresh.

• Remove the bean hopper and empty any remaining beans into an airtight container. Wash the hopper with warm water and dry it completely before reuse.
• Grind any leftover beans into powder, then sweep them out of the burr chamber using a brush. This removes built-up coffee dust and residue.

Frequently Asked Questions

How often should I backflush my espresso machine with water only?

You should backflush your espresso machine with just water (no cleaning powder) daily or after every session using dairy. This clears out coffee oils and milk residue without chemicals. Use the same method: insert a blind disc, run the 60ml button until ‘cleaning’ appears, then release.

What temperature should I use to clean the steam wand?

Heat the steam wand with about 300ml of cold water in a 600ml pitcher. The ideal cleaning temperature is around 60°C. Avoid using boiling water, which can damage the wand’s inner seals or tubing.

Do I need to remove the shower screen weekly?

Yes. For a proper weekly clean, you should unscrew and remove the shower screen (the metal filter plate inside the group head) along with the portafilter baskets. Wipe them down and soak the filters and baskets in a solution of hot water and 5g of espresso machine cleaner.

Can I soak rubber gaskets in cleaning solution?

No. Never soak rubber gaskets, silicone seals, or the drip tray in the cleaning solution or hot water with cleaner. These materials degrade when exposed to cleaning agents. Clean them with a damp cloth only.

How often should I clean coffee oils from my grinder?

You should clean out old beans and coffee dust from your grinder every week, especially the burrs and bean hopper. Leftover oils cause rancidity and affect shot flavor. Grind unused beans to clear the burrs, then brush out all residue.
