Simple habits and regular maintenance to keep your espresso machine running smoothly.

Owning a La Marzocco means bringing professional espresso equipment into your home, but taking care of it doesn’t have to be complicated. A few consistent habits, the right water, and some occasional maintenance can go a long way toward keeping your machine in good working condition.

Whether you have a Linea Micra, Linea Mini, or GS3, here’s what you should know about turning your machine on and off, daily cleaning, and longer-term maintenance.

Water Quality Is One of the Most Important Things to Get Right

If there’s one thing we want every La Marzocco owner to pay attention to, it’s water quality.

The water going into your machine affects both the flavor of your espresso and the long-term health of your equipment.

Water that’s too high in certain minerals can contribute to scale buildup inside the boilers and other components. Water that’s too low in minerals can also create problems, including difficulties with the machine’s water-level sensing system.

Not all bottled, filtered, or reverse-osmosis water is suitable for use in a La Marzocco.

We recommend using water that meets La Marzocco’s published specifications and reaching out to the La Marzocco Home team if you’re unsure what water is appropriate in your area.

Getting your water right from the beginning is one of the best ways to help prevent avoidable service issues.

Turning Your Machine On and Off

One question we hear from new owners is whether turning their espresso machine off overnight means they need to complete an extensive cleaning or boiler refresh before using it again.

For normal home use, the answer is no.

If your machine has been off for eight hours or overnight, you don’t need to drain the boilers or complete a special reset before making espresso. Simply allow the machine to reach its operating temperature, give the grouphead a quick flush, and you’re ready to begin brewing.

For everyday use, you can take advantage of the scheduling feature in the La Marzocco Home app to have your machine turn on and off around your routine. You can also turn it off manually when you’re finished making espresso.

If you’re leaving town for an extended period, turn your machine off and unplug it. Depending on how long you’ll be away, you may also want to empty and clean the water reservoir before returning to your regular routine.

Daily Cleaning: The Little Things Matter

The most important cleaning habits are also the easiest to remember.

Flush your grouphead. Before pulling a shot, run a little water through the group. After brewing, give it another quick flush to rinse away any remaining coffee grounds or residue. Keeping the group area clean helps prevent coffee oils and buildup from accumulating.

Purge and wipe your steam wand. Before steaming milk, briefly open the steam wand to release any condensation. Once you’ve finished, immediately wipe the wand with a clean, damp cloth and purge it again.

These simple steps prevent milk from drying onto the wand and help keep milk residue from entering the steam system. Never leave your steam wand sitting in milk or another liquid, especially when the machine is cooling down.

Keep your portafilter and basket clean. Rinse away leftover coffee grounds and regularly clean the basket and portafilter to remove built-up oils. Don’t forget to empty and rinse your drip tray, too!

These steps take very little time but make a noticeable difference in keeping your machine clean and ready for the next espresso.

Backflushing and Regular Cleaning

In addition to your daily routine, your machine needs occasional deeper cleaning.

Depending on how frequently you’re making espresso, plan to backflush your machine with the espresso machine cleaning detergent that comes with your machine. For regular home use, we recommend backflushing every 1-2 weeks.

Backflushing removes coffee oils and residue from inside the brewing system that a normal grouphead flush won’t reach.

It’s also a good time to clean the areas that are easy to overlook:

• Portafilter and filter baskets
• Grouphead and shower screen
• Drip tray and drain box
• Exterior machine surfaces

Refreshing Your Steam Boiler and Cleaning the Internal Water Reservoir 

A few times a year you can clean out the internal water reservoir. Use a mild soap as needed, rinse thoroughly, and avoid harsh cleaning products that could damage the machine. 

Your steam boiler also benefits from occasional attention. La Marzocco Home recommends periodically refreshing the water in the steam boiler, approximately every 2-6 months depending on use. This helps prevent water from sitting in the boiler for extended periods, particularly if you don’t use the steam wand or hot water spout very often.

The exact procedure varies by model, so always follow the instructions for your machine. Take extra care when working with hot water, as the steam boiler operates at high temperatures.

These are both periodic maintenance tasks, not something you need to do every time you turn your machine off.

When to Replace Your Grouphead Gasket and Screen

Over time, a few parts of your machine will naturally experience wear.

The grouphead gasket creates the seal between the portafilter and group. As it ages, it can become hard or worn, which may cause leaking around the portafilter during brewing. If you’re no longer getting a proper seal, it may be time for a replacement.

The shower screen, sometimes called the dispersion screen, can also accumulate coffee oils and residue over time. Regular cleaning helps, but if buildup becomes difficult to remove or the screen is damaged, replacing it may be the best option.

We recommend using genuine La Marzocco replacement parts rather than third-party alternatives to ensure proper fit and compatibility with your machine.

Preventative Maintenance

Even with a great cleaning routine, professional espresso equipment benefits from occasional service.

We recommend having a qualified espresso machine technician perform preventative maintenance approximately once a year, depending on how frequently you use your machine and your water conditions.

A technician can inspect components, check for wear, and address developing issues before they turn into bigger problems.

Routine cleaning is something you can comfortably handle at home. More involved mechanical repairs, internal inspections, and boiler service should be left to a qualified technician. And remember, you should never attempt to descale your La Marzocco yourself.

Keep It Simple

Maintaining your La Marzocco doesn’t need to become another complicated part of your day.

Start with a few good habits:

• Flush the grouphead before and after brewing.
• Purge and wipe the steam wand every time you use it.
• Keep your portafilter, baskets, and drip tray clean.
• Backflush regularly.
• Use water that meets La Marzocco’s requirements.
• Refresh your steam boiler periodically.
• Schedule preventative maintenance with a qualified technician.

These machines are built to make espresso, and regular use paired with a consistent cleaning routine is one of the best ways to keep them performing well.

If you’re ever unsure about a cleaning procedure, the water you’re using, or whether your machine needs service, reach out to the La Marzocco Home team. We’re happy to help you understand what your machine needs and how to take care of it.

A little regular maintenance goes a long way toward many years of great espresso at home.
