How to Keep Your Coffee Machine Running Like New (It's Easier Than You Think)

Your coffee machine is begging for a little attention

You wouldn't drive a car for two years without an oil change. But plenty of us drop $500 or more on a coffee machine and then never do anything beyond rinsing the portafilter under the tap. Then we wonder why our espresso tastes progressively worse over six months.

The good news? Keeping a coffee machine in top shape is genuinely easy. We're talking a couple of minutes a day, a slightly more thorough clean once a week, and a proper descale every month or two. That's it. Here's exactly what to do, broken down by the type of machine you've got.

The daily habits (two minutes, no excuses)

These apply to pretty much every machine in our coffee machine rankings, from the $71 AUSPURE drip filter to the $828 Breville Barista Express Impress.

• Flush after every shot. Run water through the group head or brewing unit for a few seconds after you pull your espresso. This washes out leftover coffee oils before they go stale and bitter. Takes about five seconds.
• Wipe the steam wand immediately. Milk that dries on a steam wand turns into cement. Purge a quick burst of steam, then wipe with a damp cloth. Every. Single. Time. Leave it once and you'll be scraping crust off with a pin.
• Empty the drip tray and knock box. Sitting water breeds mould. Old coffee grounds go funky fast. A quick dump at the end of the day keeps things fresh.

None of this takes more than two minutes. Build it into your routine and your machine will thank you with better-tasting coffee and fewer problems down the track.

The weekly clean

Once a week, give your machine a proper going-over.

For semi-automatic espresso machines like the Breville Barista Express Impress ($828, 4.6 stars) or the De'Longhi Dedica ($219, 4.2 stars), this means backflushing. Pop in a blank disc or cleaning tablet, run a few cycles of water through the group head, and you're clearing out the oils and old grounds that build up in the brewing path. Most machines come with a cleaning disc in the box. Use it.

If your machine has a built-in grinder, run a handful of fresh beans through on a coarse setting to clear out stale grounds stuck in the burrs. The Barista Express Impress's 25-setting grinder benefits from this, and so does the De'Longhi Magnifica Evo's 13-step burr grinder.

Got a milk frother? The Magnifica Evo ($729, 4.4 stars) has an auto-clean cycle for its LatteCrema system, which handles most of the work. For machines with a manual steam wand, soak the tip in warm water with a drop of detergent for ten minutes, then run steam through to clear the line. Dried milk inside a steam wand is the number one reason home baristas end up with flat, lifeless foam.

Descaling: the one thing you absolutely cannot skip

This is where most people fall down. Descaling removes mineral buildup from inside your machine's boiler and pipes, and in Australia, it matters more than you might think.

Water hardness varies across the country. Melbourne and Sydney sit in the soft to moderate range, but parts of Adelaide, Brisbane and Perth have genuinely hard water. Hard water means calcium deposits build up faster, narrowing the pipes, reducing water flow, and eventually giving your machine heart failure.

How often? Every two to three months for most machines, or sooner if your area has particularly hard water. Some machines will tell you when it's time - the Magnifica Evo has a descale indicator, and the Nespresso Vertuo Pop ($179, 4.1 stars) alerts you after a certain number of pods. Don't ignore these warnings. They're not suggestions.

Use your machine's recommended descaling solution. White vinegar is tempting but can leave a lingering taste and isn't always safe for internal rubber seals. A proper descaling kit costs about $15 and lasts several rounds. Worth it to protect a machine that cost you hundreds.

The Breville Bambino Plus ($527, 4.3 stars) is worth a mention here. Its compact water tank means you're refilling frequently, which also means fresh water cycles through more often. That's actually a small advantage - less time for standing water to deposit minerals.

What each machine type needs

Here's a quick cheat sheet based on the machines in our coffee machine lineup:

Semi-automatic espresso machines (Barista Express Impress, Bambino Plus, Dedica) need the most attention. Daily flushing and wiping, weekly backflushing, regular descaling, and occasional gasket and shower screen checks. The trade-off is you get the best espresso quality - the Barista Express Impress scores 9.3 for espresso quality for a reason.

Bean-to-cup automatics (Magnifica Evo) do a lot of the work for you. Auto-rinse cycles run on startup and shutdown, and the machine will prompt you for descaling and cleaning tablet cycles. You still need to empty the grounds container and clean the brew group weekly, but it's less hands-on than a semi-auto.

Pod machines (Vertuo Pop) are the easiest to maintain. Regular descaling is basically the whole routine. Run water through the system between pod types if you're switching flavours, and clean the capsule holder every now and then. That's it.

Drip filter machines (AUSPURE AusBrew-1812, $71, 4.5 stars) just need a rinse of the carafe and filter basket after each use, and a descale every couple of months. The simplest machine, the simplest maintenance.

Warning signs your machine is overdue for a clean

If you're noticing any of these, your machine is trying to tell you something:

• Coffee tastes bitter or burnt - stale oils building up in the group head or grinder
• Shots pull too fast or too slow - scale buildup affecting water pressure and flow
• Milk won't froth properly - dried milk blocking the steam wand or frother nozzle
• Water takes ages to heat - mineral deposits insulating the boiler element
• Strange noises from the pump - working harder than it should against mineral restrictions

Most of these are fixable with a good descale and backflush. But leave them too long and you're looking at a service call or, worse, a replacement machine that costs you all over again.

Protect the investment

Coffee machine maintenance isn't glamorous, but it's the difference between a machine that makes brilliant coffee for five years and one that starts tasting off after six months. Two minutes a day, ten minutes a week, and one proper descale every couple of months. That's genuinely all it takes.

And honestly, the most expensive part of your coffee setup isn't the machine - it's the beans and pods you'll buy over its lifetime. Looking after the machine properly means you're getting the best possible result from every cup you make with it.
