Coffee Machine Maintenence - How to keep every cup perfect.

Whether you’re running a busy café or brewing espresso at home, your coffee machine is the heart of your setup. But even the best machines need a little TLC. Regular maintenance not only keeps your coffee tasting its best but also extends the life of your machine and prevents costly breakdowns.

Here’s how to keep your coffee machine running like new.

1. Daily Cleaning – The Foundation of Great Coffee

Every shot of espresso leaves behind microscopic coffee particles and oils. Left alone, these can affect flavour and damage your machine.

  • Backflush the group heads with water after every shift (or daily at home).

  • End-of-day clean: backflush with a specialist cleaning powder or tablet.

  • Wipe and purge steam wands after every use to prevent milk build-up.

  • Empty and rinse drip trays to avoid bacteria and bad smells.

  • Clean portafilters and baskets with hot soapy water to remove coffee oils.

2. Weekly Deep Clean – Going Beyond the Surface

Even with daily cleaning, some areas need a more thorough approach.

  • Soak portafilters and baskets overnight in espresso machine cleaning solution.

  • Remove and clean shower screens to improve water flow.

  • Check steam wand tips for blockages and clear them with a pin.

3. Monthly & Quarterly Maintenance – The Long-Term Care

Just like a car, your coffee machine needs periodic servicing.

  • Descale to prevent limescale build-up (especially in hard water areas).

  • Inspect and replace group seals if they’re worn or leaking.

  • Check pressure gauges and water filters to ensure consistent performance.

4. Troubleshooting – Common Issues & Quick Fixes

Problem Likely Cause Quick Fix
Espresso tastes bitter Dirty group head / burnt oils Deep clean immediately
Water leaking from group head Worn seal Replace seal
Steam wand low pressure Blocked tip / scale build-up Clean tip / descale

Closing Tip:
Think of your coffee machine like a sports car — the better you look after it, the better it performs. A few minutes of daily care will save you hours of repairs and ensure every customer (or guest) gets the perfect cup.


1. Top 5 Espresso Machine Mistakes (and How to Avoid Them)
Even the best beans won’t save a bad shot if your machine isn’t looked after properly. From home setups to busy cafés, pubs, and restaurants, these are the most common espresso machine mistakes — and how to fix them.
Mistake 1: Not Purging the Steam Wand
Leftover milk burns onto the wand, spoils flavour, and creates hygiene risks.
✅ Always wipe and purge before and after every use.
Mistake 2: Forgetting Daily Backflushing
Coffee oils build up quickly and cause bitterness.
✅ Flush with water daily, use detergent weekly.
Mistake 3: Using Hard Water Without Filtration
Scale is the number one cause of machine breakdowns.
✅ Invest in water filters or softeners — it saves thousands in repairs.
Mistake 4: Ignoring Gaskets and Seals
Leaking group heads ruin shots and waste time.
✅ Replace gaskets every few months (cheap, quick, essential).
Mistake 5: Skipping Grinder Care
Dirty grinders make every coffee taste stale.
✅ Brush daily, deep clean weekly.
👉 With the right training, these habits become second nature. Platforms like Elevate make it easy to standardise machine care across your team.
2. When to Service Your Espresso Machine (Before It Breaks Down)
Espresso machines rarely just “die.” They give warning signs — but only if you know what to look for.
Warning Sign 1: Inconsistent Shot Times
If your extractions suddenly slow down or speed up, it could be scale or pump issues.
Warning Sign 2: Water Leaks
Drips around the group head, steam wand, or drip tray are early gasket failures.
Warning Sign 3: Weak Steam Pressure
Struggling to texture milk? Your boiler may need descaling or servicing.
Warning Sign 4: Strange Noises
Grinding, hissing, or irregular pumping sounds should never be ignored.
Service Frequency
  • Busy cafés, pubs, bars, restaurants: Every 6 months
  • Smaller volume sites & home users: Every 12 months
  • Always descale based on water hardness.
👉 Regular servicing prevents breakdowns, protects flavour, and keeps your team confident. Training your staff through Elevate helps spot issues before they become expensive repairs.
3. Building a Maintenance Culture in Your Business
Equipment breaks, standards slip, and waste grows when maintenance is seen as “someone else’s job.” The solution? A maintenance culture that makes equipment care part of daily operations.
Why Culture Matters
  • Consistency: Customers taste the difference when machines are clean.
  • Efficiency: Quick daily checks prevent downtime during peak hours.
  • Cost savings: Replacing a £5 gasket is cheaper than a £500 service call.
How to Build It
  1. Train Everyone – baristas, chefs, and supervisors should all know basic upkeep.
  2. Make It Routine – daily/weekly/monthly checklists (like those in Elevate) keep tasks clear.
  3. Reward Ownership – celebrate teams that keep equipment spotless and reliable.
  4. Lead by Example – if managers ignore standards, staff will too.
👉 With Elevate Pro, you can embed maintenance routines into onboarding, toolbox talks, and compliance modules — creating lasting habits that protect your equipment and your profits.
4. How Training Cuts Down Coffee Waste
Coffee waste doesn’t just hit your bottom line — it damages consistency, morale, and customer experience. Most waste is avoidable with the right training.
The Common Culprits
  • Dial-in errors – too coarse or too fine = repeated wasted shots.
  • Milk wastage – over-steaming or reheating milk instead of texturing fresh.
  • Poor portioning – overfilled portafilters, oversized servings.
  • Expired bakery/ingredients – caused by poor rotation and stock control.
The Fix: Training & Visibility
  • Staff learn to dial in correctly and adjust consistently.
  • Standard milk texturing cuts waste while improving quality.
  • Portion control becomes a habit, not an afterthought.
  • Waste tracking (built into Square + Elevate) helps managers adjust orders.
👉 The result? Less waste, higher margins, and happier customers. Training staff through Elevate means waste isn’t just logged — it’s prevented.
5. Toolbox Talks for Coffee Teams
Toolbox talks aren’t just for construction sites — they’re a powerful way to keep coffee teams sharp, safe, and consistent.
What’s a Toolbox Talk?
A short, focused discussion on a specific topic, delivered on shift. Quick, practical, and easy to absorb.
Why They Work in Coffee
  • Reinforces training in real time.
  • Helps staff connect the “why” behind procedures.
  • Provides a platform for feedback and continuous improvement.
Examples for Coffee Teams
  • Milk Safety: Why reheating milk is unsafe and wasteful.
  • Grinder Checks: How to clean and calibrate quickly.
  • Allergen Awareness: Handling alternative milks safely.
  • Customer Service: Handling busy periods with consistency.
How to Deliver Them
  • Keep it 5–10 minutes max.
  • Use real examples from that week.
  • Log in Elevate with a Stopcard for accountability.
