How to Maintain Your Home Espresso Machine

If you've just brought home a shiny new espresso machine, you're probably eager to pull perfect shots—but without proper care, even the best machine can quickly lose performance. Mineral buildup, dirty filters, and improper usage will degrade your espresso over time. What’s the right way to maintain your machine so it keeps brewing great espresso for years?

To maintain your home espresso machine properly, descale it 2–5 times per year depending on water hardness, clean filters and parts after every use, and always wipe down and store the machine safely. Follow our step-by-step guide to extend its life and maintain espresso quality.

Read the Manual First

When you first get your espresso machine, don’t plug it in right away. Take time to read the instruction manual carefully. Check that the voltage matches your local power supply, and note any special warnings or operating instructions. Using the machine improperly from the start—such as plugging it into the wrong voltage—can cause permanent damage.

Inspect Power and Clean Before First Use

Once installed, double-check that the power cord is firmly connected and free of cracks or fraying to prevent electrical hazards. Then, give the water tank a thorough cleaning. Boil water and use it to disinfect the inside of the tank, removing dust and ensuring a hygienic start. This simple step helps avoid contamination in your early brews.

Never Dry Fire or Overfill

Espresso machines should never be run dry—without water—because the heating element can overheat and burn out. At the same time, don’t overfill the water tank. Too much water can cause boiling overflow, soaking the heating components. Also, be careful not to splash water onto any electrical parts during filling, as moisture can degrade insulation and create shock or malfunction risks.

Remove New Machine Smells Before Brewing

New espresso machines often have a strong plastic smell due to manufacturing residues. This odor can affect the taste of your early shots. Before brewing coffee, run two full cycles of just hot water through the machine. This helps burn off the plastic smell and ensures your first cups of espresso taste clean.

Descaling: How Often and How To

Over time, mineral deposits from water—mainly calcium and magnesium—build up inside the machine, especially in the boiler and brew group. This scaling reduces efficiency and can alter shot quality. Descale your machine 2–5 times per year, depending on how hard your local water is.

To descale: Add 2 cups of fresh water and 50ml of white vinegar or food-grade descaling solution to the water tank. Run the machine through a normal brewing cycle to let one cup’s worth of the solution drip through. Let it sit for 20 minutes, then run the rest of the solution through completely. Afterward, turn off the machine and wait 5 minutes. Flush the system by running 1–2 full tanks of clean water through to rinse away any residue. This keeps your machine running efficiently and your espresso tasting pure.

Cleaning Filters and Screens

The coffee filter basket (or shower screen) and portafilter mesh collect coffee oils and grounds. Over time, these residues clog the flow and affect extraction. To clean: Remove the portafilter and soak the filter basket and any metal screens in warm water for a few minutes. Gently rinse them under running water, flushing both sides until clean. Never use metal scrapers or abrasive pads—they can scratch and damage the fine mesh, leading to uneven water flow and channeling.

Safe Disassembly and Wiping

When cleaning, never submerge the whole machine in water. Instead, carefully remove individual parts like the filter basket, portafilter, and other removable components. Wash those separately. For non-removable parts such as the exterior or control panel, use a soft, damp cloth to wipe down surfaces. Avoid spraying cleaners directly onto the machine.

Drying and Storage

After each use or cleaning session, always dry all parts thoroughly with a clean towel. Store the machine in a safe place, out of reach of children. Don’t leave it upside down or place heavy objects on top of it, which could damage internal components or the water reservoir.

Frequently Asked Questions

How often should I descale my home espresso machine?

Descaling should be done 2–5 times per year, depending on the hardness of your tap water. If you notice slower extraction or reduced steam power, it may be time to descale even if it hasn’t been a full year.

Can I use vinegar to descale my espresso machine?

Yes, you can use 50ml of white vinegar mixed with 2 cups of water as a descaling solution. Let it sit in the machine for 20 minutes, then flush thoroughly with clean water afterward. For a gentler option, food-grade descaling solutions are also effective.

Is it okay to leave water in the tank?

It’s generally safe to leave water in the tank if you’re using the machine regularly, but always ensure it’s clean and fresh. If the machine will sit unused for a few days, empty the tank to prevent stagnation or mineral issues.

What’s the safest way to clean the filter basket?

Soak the filter basket in warm water for a few minutes, then rinse it gently under running water. Avoid using brushes with hard bristles or metal tools, which can damage the fine mesh and disrupt water flow during extraction.

Can I run my espresso machine without coffee to clean it?

Yes. Running plain hot water (or a vinegar-water mix during descaling) through the machine without coffee is a common way to clean the brew path. This is part of both regular maintenance and descaling procedures.
