How to Clean Espresso Machine Like a Barista: Step-by-Step Guide

Is your espresso tasting bitter or weak? The problem might not be your beans—it could be a dirty machine! Just like any high-performance appliance, your espresso machine needs regular cleaning to function at its best. Coffee oils, mineral buildup, and leftover grounds can clog your machine, alter the flavor of your brew, and even shorten its lifespan.

In this guide, we’ll walk you through how to clean an espresso machine the right way—covering daily, weekly, and monthly maintenance routines. Whether you own a semi-automatic, super-automatic, or manual espresso maker, these steps will ensure your machine stays in top shape, delivering rich, flavorful coffee every time.

Let’s dive in!

Daily Cleaning Routine (Essential for Fresh Coffee)

A clean espresso machine starts with simple daily habits. Skipping these steps can lead to clogged filters, stale coffee residue, and even bacterial growth. Here’s what you should do after every use:

A. Flush the Group Head

The group head (where the portafilter locks in) collects coffee oils and fine grounds. If left uncleaned, these residues can turn rancid and ruin your espresso’s taste.

• Step 1: Remove the portafilter and run water through the group head for 5-10 seconds.
• Step 2: For deeper cleaning, use a blind filter (a basket with no holes) and backflush with water (if your machine supports it).

🔹 Pro Tip: Wipe the group head’s rubber gasket with a damp cloth to prevent coffee buildup.

B. Clean the Steam Wand

Milk residue hardens quickly inside the steam wand, leading to blockages and bad-tasting lattes.

• Step 1: Immediately after steaming, purge the wand by releasing steam for 2-3 seconds.
• Step 2: Wipe it with a damp microfiber cloth to remove milk residue.
• Step 3: For stubborn buildup, soak the wand tip in warm, soapy water.

🚨 Warning: Never leave milk dried on the wand—it can clog the steam valve!

C. Empty & Rinse the Drip Tray & Portafilter

• Drip Tray: Coffee drips and water can stagnate, leading to mold. Empty and rinse daily.
• Portafilter & Basket: Knock out used grounds and rinse under hot water to remove oils.

📌 Quick Checklist for Daily Cleaning:
✅ Flush group head
✅ Wipe steam wand
✅ Empty drip tray
✅ Rinse portafilter

By following these steps, your machine will stay fresh and ready for the next brew!

Weekly Deep Cleaning (For Optimal Performance)

While daily cleaning keeps things functional, a weekly deep clean tackles hidden buildup. Here’s how to do it right:

A. Backflush with Cafiza (For Machines with a 3-Way Valve)

Backflushing forces water backward through the machine, removing trapped coffee oils.

Steps:

1. Insert a blind filter into the portafilter.
2. Add 1 tsp of Cafiza (or espresso machine cleaner) into the basket.
3. Lock the portafilter in and run a 10-second brew cycle.
4. Repeat 3-5 times until the water runs clear.

🛠 Note: Check your machine’s manual—some models require a specific backflushing routine.

B. Soak Removable Parts

Coffee oils cling to metal parts, affecting flavor.

• Portafilter & Basket: Soak in hot water + detergent for 15 mins, then scrub with a brush.
• Steam Wand Tip: Soak in a vinegar-water mix (1:1) to dissolve milk deposits.

C. Clean the Shower Screen

The shower screen (inside the group head) can get clogged with fine coffee particles.

• Remove it (check your manual for instructions).
• Soak in Cafiza solution, then scrub gently with a toothbrush.

📊 Weekly Cleaning Time Breakdown:

Task	Time Required
Backflushing	10-15 mins
Soaking parts	15-20 mins
Shower screen cleaning	5 mins

A weekly deep clean ensures your espresso tastes as good as day one!

Monthly Maintenance (Keep Your Machine Like New)

Even with regular cleaning, mineral deposits from water can build up inside your machine over time. This is why monthly descaling and deep cleaning are crucial for maintaining performance and extending your espresso machine’s lifespan.

A. Descaling: Remove Harmful Mineral Buildup

Hard water contains calcium and magnesium that form scale deposits in your machine’s heating elements and pipes. Left untreated, this can:

• Reduce heating efficiency
• Cause clogs in water flow
• Lead to bitter-tasting espresso

How to Descale Your Espresso Machine:

1. Prepare Your Descaler
   • Use a commercial descaling solution (like Urnex Dezcal) or a natural alternative (1:1 water and white vinegar).
   • Always check your machine’s manual first—some manufacturers recommend specific products.
2. Run the Descale Cycle
   • Fill the water tank with the descaling solution.
   • Turn on the machine and run water through the group head and steam wand until the tank is half empty.
   • Turn off the machine and let it sit for 15-20 minutes to allow the solution to break down deposits.
   • Turn it back on and flush the remaining solution through.
3. Rinse Thoroughly
   • Refill the tank with clean water and run 2-3 full tanks through the machine to remove any leftover descaling residue.
   • Taste a shot of plain water to ensure no vinegar or chemical aftertaste remains.

🔹 Pro Tip: If your area has very hard water, consider descaling every 2-3 weeks instead of monthly.

B. Deep Clean the Water Tank & Internal Components

• Remove the water tank and wash it with warm, soapy water to prevent bacterial growth.
• Use a soft brush to clean any hard-to-reach areas where mold or residue may accumulate.

C. Check & Lubricate Moving Parts (If Applicable)

Some high-end espresso machines have lever-based mechanisms that benefit from occasional lubrication.

• Apply a food-safe lubricant (like Molykote 111) to the group head gasket and lever joints.
• Wipe away excess to prevent contamination of your coffee.

📌 Monthly Maintenance Checklist:
✅ Descale the machine
✅ Clean the water tank
✅ Inspect gaskets and seals
✅ Lubricate moving parts (if needed)

By following these steps, your espresso machine will stay in peak condition for years!

Pro Tips for Longevity & Better-Tasting Espresso

Want to take your espresso machine care to the next level? These professional maintenance tips will help you avoid common problems and keep your coffee tasting amazing.

A. Use Filtered or Softened Water

• Hard water accelerates scale buildup and can damage internal components.
• If your tap water is hard, use a brita filter or bottled soft water.

B. Replace Worn-Out Parts Annually

• Group head gasket (becomes hard and leaks over time)
• Shower screen (clogs with fine coffee particles)
• Portafilter baskets (warp or wear out with daily use)

C. Never Leave Coffee Grounds Sitting in the Portafilter

• Old grounds turn rancid and contaminate fresh coffee.
• Always knock out and rinse the portafilter immediately after brewing.

D. Follow Manufacturer-Specific Guidelines

• Some machines (like DeLonghi, Breville, or La Marzocco) have unique cleaning requirements.
• Always check the user manual for tailored maintenance advice.

📊 Espresso Machine Lifespan Comparison

Maintenance Level	Expected Lifespan
Poor (Rarely cleaned)	2-3 years
Moderate (Basic cleaning)	5-7 years
Excellent (Regular deep cleaning)	10+ years

Taking these extra steps ensures your machine performs like new and your espresso tastes perfect every time!
