How often should you clean your espresso machine

How Often Should You Clean Your Espresso Machine? The Complete UK Guide

📅 March 2025  ·  ☕ 5 min read  ·  Espresso Maintenance

If you own an espresso machine — whether it's a Sage Barista Express, a De'Longhi La Specialista or any other home espresso machine — cleaning it regularly is the single most important thing you can do to protect your investment and keep your coffee tasting great.

Yet most home baristas in the UK clean their machine far less often than they should. In this guide, we'll cover exactly how often you need to clean your espresso machine, what happens if you don't, and the easiest way to do it.

The Golden Rule: Every 200 Shots

The industry standard recommended by most espresso machine manufacturers is to backflush your machine every 200 espresso shots, or approximately once per week for a machine used daily. For machines used less frequently — perhaps 1–2 shots per day — cleaning every 2 weeks is acceptable.

However, if you notice any of the following, clean immediately regardless of shot count:

  • Espresso tastes bitter, sour or "off"
  • Visible brown or black residue around the group head
  • Reduced flow rate or unusual pressure
  • Your machine prompts a cleaning cycle warning

What Happens If You Don't Clean Your Espresso Machine?

Coffee contains natural oils that, over time, oxidise and go rancid inside your machine. These oils coat the group head, shower screen and portafilter — and they will make your espresso taste increasingly bitter and stale, no matter how good your coffee beans are.

Beyond taste, coffee oil build-up can cause long-term mechanical damage to your machine's internal components, potentially shortening its life by years and requiring costly repairs.

Daily, Weekly & Monthly Cleaning Schedule

After every use: Purge the group head with a 5-second water flush. Wipe the steam wand after every use.

Weekly: Backflush with a cleaning tablet (like Qualità Napoli espresso cleaning tablets). Remove and rinse the portafilter and basket.

Monthly: Remove and deep-soak the shower screen and portafilter in hot water. Descale the internal water circuit with a descaling tablet.

The Easiest Way to Clean Your Espresso Machine

The simplest and most effective method for weekly cleaning is using a backflush cleaning tablet. Place one tablet in your blind basket, run a backflush cycle, then rinse. The whole process takes under 5 minutes and removes all coffee oil residue from your group head and internal circuit.

Qualità Napoli espresso machine cleaning tablets are compatible with all major UK espresso machine brands and are available in 10, 20 and 30-packs — making it easy and affordable to keep your machine in perfect condition.

The Beginner's Guide to Backflushing Your Espresso Machine

📅 February 2025  ·  ☕ 6 min read  ·  How-To Guide

Backflushing is one of the most important — and most misunderstood — aspects of espresso machine maintenance. If you've just bought a Sage, De'Longhi or Breville espresso machine and want to keep it running perfectly, this guide is for you.

In this article, we'll explain exactly what backflushing is, why it matters, which machines support it, and how to do it step by step using espresso cleaning tablets.

What Is Backflushing?

Backflushing is the process of forcing water and cleaning solution back through the group head and internal valves of your espresso machine — in the opposite direction to normal water flow. This dislodges and flushes out coffee oils, grounds and residue that accumulate with each shot.

It is only possible on machines fitted with a three-way solenoid valve — which includes most prosumer home espresso machines and all commercial machines. Machines without a solenoid valve (such as basic pod machines) cannot be backflushed.

Which Machines Can Be Backflushed?

The following popular UK espresso machines support backflushing:

  • Sage Barista Express, Barista Pro, Barista Touch
  • De'Longhi La Specialista, Dedica Arte
  • Breville Barista Express, Infuser
  • Gaggia Classic, Classic Pro
  • Rancilio Silvia
  • Most commercial and semi-commercial espresso machines

What You'll Need

  • A blind basket (blank basket with no holes — usually included with your machine)
  • Espresso cleaning tablets — one per cleaning session
  • 5 minutes of your time

How to Backflush Step by Step

Step 1: Remove your regular basket from the portafilter and insert the blind basket.

Step 2: Place one Qualità Napoli cleaning tablet into the blind basket.

Step 3: Insert the portafilter into the group head as normal and lock it in place.

Step 4: Start the pump for 10 seconds, then stop for 5 seconds. Repeat this 5–8 times. The tablet will dissolve and be forced through the group head.

Step 5: Remove the portafilter and rinse the blind basket under hot water.

Step 6: Reinsert the clean blind basket and run 3–4 cycles of clean water to flush out any residue.

Step 7: You're done. Your group head is clean and your machine is ready to brew its best espresso.

How Often Should You Backflush?

Weekly for daily-use machines, or every 200 shots. If you can see coffee residue or your espresso is tasting off, backflush immediately.

5 warning signs your espresso machine needs cleaning

5 Warning Signs Your Espresso Machine Urgently Needs Cleaning

📅 January 2025  ·  ☕ 4 min read  ·  Espresso Tips

Most espresso machine owners clean their machines far less often than they should — and their coffee pays the price. The problem is that coffee oil build-up happens gradually, so you might not even notice how much your espresso has deteriorated until you clean the machine and taste the difference.

Here are the 5 most common warning signs that your espresso machine urgently needs a clean with backflush cleaning tablets.

1. Your Espresso Tastes Bitter or "Off"

This is the most obvious sign. If your espresso has developed a harsh, bitter or unpleasant aftertaste that wasn't there before, rancid coffee oil build-up is almost certainly the cause. Old coffee oils oxidise over time and contaminate each new shot you pull — no matter how good your beans are.

A single backflush with a cleaning tablet can restore your espresso's flavour immediately.

2. Visible Dark Residue Around the Group Head

Take a look at your machine's group head — the part the portafilter locks into. If you can see a dark brown or black film of residue around it, your machine is well overdue a clean. This residue is compacted coffee oil and grounds that will continue to contaminate every shot until removed.

3. Slow or Inconsistent Flow Rate

If your espresso is taking longer to extract than usual, or the flow seems inconsistent or uneven, this can indicate that the shower screen or internal valve is partially blocked with coffee residue. Backflushing with an espresso cleaning tablet will clear the blockage and restore normal pressure and flow.

4. Your Machine's Cleaning Light Is On

Many modern espresso machines — including Sage and De'Longhi models — have built-in cleaning cycle alerts. If this light is on, your machine is telling you it needs a clean right now. Don't ignore it. Running the machine in this state can cause long-term damage to internal components.

5. The Portafilter Smells Stale

Give your portafilter a sniff after removing it from the group head. If it smells rancid, musty or strongly of stale coffee rather than fresh roasted beans, you have significant oil build-up that needs addressing. A thorough backflush with cleaning tablets, followed by soaking the portafilter basket in hot water, should resolve this immediately.

The Fix: One Tablet, Five Minutes

All five of these problems can be solved with a single Qualità Napoli espresso cleaning tablet and five minutes of your time. Our Italian-formula backflush tablets dissolve completely, removing all coffee oil and residue — and the difference in your espresso's taste will be immediately noticeable.
