If your morning cup of coffee is one of the highlights of your day, you've likely got a lot of love for the appliance that delivers it to you each morning.
And if you've splashed out a few hundred – or a few thousand – dollars on a sparkling new coffee machine, you're going to want to take care of it to ensure it continues brewing up the good stuff for many years to come.
"It's essential to keep your espresso machine clean and well-maintained – not only will it help the machine last longer but a clean machine equals great-tasting coffee," says CHOICE coffee machine expert Adrian Lini.
"If you've spent a lot of money on a machine, the last thing you want is for it to become faulty because you haven't looked after it properly."
We've tested to find you the best.
"I recommend that every time you use the machine, you should give it a quick clean," Adrian says. "That includes wiping the steam wand, and rinsing the group head and drip tray."
"If you find you've left it for too long, you may need to use warm soapy water."
The steam wand, drip tray and group head are the areas you should focus on cleaning each time you use your machine:
Read the instruction manual to make sure you're following the manufacturer's recommendations for your machine.
"If you leave a drip tray with coffee in it for a couple of days it becomes a nightmare to clean, compared to cleaning it immediately after use," says Adrian.
"It's a great habit to get into and will save you loads of time in the long run. Mould absolutely loves coffee, so regular cleaning will save you having to deal with a mouldy machine."
Here's our step-by-step cleaning guide: How to clean your coffee machine.
Your coffee machine's water filter helps to prevent scale build-up which can affect the performance of your machine over time, potentially causing blockages and heating problems.
Make sure you're familiar with your machine's instruction manual so you know how frequently to change the water filter (if your machine has one). And keep a close eye on it as you're using it.
If you live in a hard water area, you'll find that you need to change the water filter more frequently.

Over time, mineral deposits build up on your machine's boilers and internals. How often you need to descale depends on the hardness of the water in your area. It keeps everything running smoothly. If you don't regularly descale the machine, it could clog up and stop working
Some of the more expensive machines will have indicators that will tell you when your machine needs cleaning and descaling.
Your best bet is to read through the manual and stick to what the manufacturer says.
Mould loves coffee, so be sure to clean your drip tray after use.
Your coffee grinder is an important part of the coffee-making process: if you grind the beans incorrectly, no amount of latte art or perfectly-timed extraction will make the coffee taste any good. So keeping your grinder happy is key to enjoying delicious coffees.
One thing to keep in mind before you start fiddling with your grinder: they can be extremely sharp, so be very careful!
Soap and coffee grinders generally don't mix. "Make sure you read the instructions for the specific grinder you have, but often you shouldn't use soap (and sometimes even water) to clean the grinder to protect the mechanisms and oils within the grinder that help it move freely and in fine increments," Adrian says.
"Sometimes it's best just to use a brush or air to clean certain components.
"As long as you aren't leaving the grinder or the machine filled with old coffee for weeks on end, and you're giving it a quick clean each time you use it, you shouldn't have any problems."

Addressing any issues as they arise is good practice in your relationship with your coffee machine. Don't ignore the little niggles – if you take care of them quickly, they'll stay little and will keep your machine happy and the quality coffee coming.
Each year CHOICE surveys thousands of Australians, asking them what appliances they have in their homes and what issues they've had. The most common reported issues with coffee machines in the most recent survey were water leaks, broken seals, issues with the water pump, or the machine just stopped working all together.
If any of these issues occur with your machine, or there's any warning signs – such as the coffee tasting bad or different, the coffee temperature not being hot enough, the pour being slower than usual or your machine making strange noises – do some troubleshooting quick smart. It may just be that the machine needs a thorough clean and descale to remove any blockages.
Consult your owner's manual as it will likely have tips for troubleshooting or contact the manufacturer to organise a repair.

"If you make multiple coffees a day then leave it on all day but always turn it off at night," says Adrian.
"If you only make coffee in the morning then turn it off after breakfast."
If you're not using your coffee machine, switch it off – leaving it on all the time ends up wearing down the machine and can make it too hot to use anyway.
Most espresso machines will turn off automatically, but it's a good idea to get into the habit of switching it off when you're finished making coffee for the day.

A high pricetag doesn't necessarily mean good performance – you can pick up some reasonably-priced machines that will deliver as good a coffee as ones worth many times more.
But when you're buying a new coffee machine, it pays to look for one made with quality components – and, better still, one that has replaceable parts should anything need repairing down the line.
Ideally, you'd want a machine that's not too plastic-y. If the machine body, group head and portafilter are made from stainless steel they're likely to last longer. All the maintenance in the world won't save a cheaply-made coffee machine!
Poorer quality machines tend to have similar problems: the portafilter and group head not fitting together well, meaning that the machine doesn't build enough pressure to make a good espresso. It's a good idea to look at a machine instore to get a feel for the machine before you buy.

So what kind of machine should you buy? "Coffee is subjective so find a machine in your price range that can match what you want out of it," says Adrian.
"A higher quality machine will have components that are similar to a commercial cafe espresso machine and therefore perform better, but not every user needs or wants that at home. A mid-range machine will make great espresso but have less fancy features and precision."
And just remember that a good machine isn't the be-all and end-all of coffee making. "It can't be stressed enough how important it is that you have a high quality and precise grinder and fresh beans when making espresso. It can make a cheap espresso machine perform way above its weight," says Adrian.
When we surveyed more than 2700 CHOICE members about their coffee machines, the most reliable mainstream brands were Breville, Sunbeam and DeLonghi. Unfortunately, this data doesn't capture information about high-end models made by smaller manufacturers, so do as much digging as you can about the particular model you're considering before you buy.
If you're careful about which coffee machine you purchase, and careful about maintaining it, you'll be able to enjoy great coffee for years to come.
