Using a New Espresso Machine for the First Time

Start by slowing down

The temptation with a new espresso machine is to load coffee and pull a shot within five minutes of opening the box. Resist it. Not because anything bad will happen, but because the first shot from an unprepared machine will taste of packing residue and disappoint you into thinking you bought the wrong thing. A little setup up front turns that first real coffee from a letdown into a genuine one.

Everything on this page is a one-time, unboxing-day routine. None of it is difficult and none of it takes special tools. Work through it in order and by the end you will have a clean, primed machine, a feel for its buttons, and realistic expectations — which is a far better place to start from than a rushed, muddy first shot. Once the machine is ready, the actual craft of getting the shot right lives in how to dial in espresso and the first-shot checklist; this page just gets you to the start line.

Unbox and wash the removable parts

As you unpack, take out everything that is designed to be removed and wash it in warm water before it ever touches coffee. That means the portafilter and its baskets, the water tank, the drip tray and its grate, the milk jug or frothing attachment if one came in the box, and any included scoop or tamper. New metal and plastic parts carry a fine film of manufacturing dust, mould-release residue and packing debris, and a quick hand-wash removes it. Plain warm water and a soft cloth are enough; you do not need detergent, and you certainly should not put any of it through the dishwasher.

While things are apart, peel off every protective sticker and film — there are usually a few on the drip tray, the body and the display — and locate the parts you will use daily so nothing surprises you mid-shot later. Check the box for a water filter, a water-hardness test strip and the manual, because the next two steps depend on them. Keep the manual; every machine has quirks, and yours is the authority where it differs from any general guide.

Fit the filter and set water hardness

Water is not a detail on an espresso machine — it is most of what is in the cup and the single biggest cause of the machine dying young, because hard water leaves scale inside the boiler and pipes. Two setup steps address it before you have made a single coffee.

Fit the water filter if your machine came with one and a housing in the tank to take it. These filters usually need a brief soak or rinse first (the manual will say), then clip into the tank. They reduce the scale-forming minerals in your water, which slows how fast the inside of the machine furs up. Set the water hardnessif your machine has that setting — many use the included test strip: you dip it in your tap water, read off the hardness, and enter that number in the menu. The machine then uses it to time its own descaling reminders correctly. Getting this right on day one means the machine nags you to descale at the right moment rather than too late. If you would rather sidestep hard-water problems entirely, our take on brewing water is in water for espresso.

Flush the machine (the break-in)

This is the step people skip and later regret. Before you brew any coffee, run several cycles of plain hot water through the machine to rinse out the last of the manufacturing residue from the parts your water and coffee will pass through. Think of it as seasoning or breaking in the machine.

With the portafilter locked in empty (or with an empty basket), run water through the group headas if pulling a shot, and let a few tankfuls' worth of cycles pass through — discarding the water each time — until it runs clean and tastes of nothing but water. Then run the steam wand: open the steam for several seconds to push hot water and steam through it, and if your machine has a hot-water spout, run that too. You are flushing every path the machine will use. The first flushes may smell or taste faintly of plastic or of new metal; that is exactly what you are rinsing away, and it fades fast. Only once the water runs clean and neutral is the machine ready to make coffee you would want to drink.

Your first, low-stakes shot

Now — and only now — make coffee, and treat the very first shot as a rehearsal rather than a performance. The goal is not a perfect espresso; it is to learn where the buttons are, how the portafilter locks and releases, how the machine sounds when the pump runs, and how long a shot takes. Use whatever coffee you have, pull a shot, and pay attention to the machine rather than the cup.

Expect it to be imperfect, because dialling in a new machine-and-grinder combination takes a few shots regardless of skill. A useful starting reference for a standard double is roughly a 1:2 ratio — about twice the weight of liquid out as coffee in — in something like 25 to 30 seconds, and then you adjust from there: too fast and sour means grind finer, too slow and bitter means grind coarser. That whole process is its own craft, and rushing it on unboxing day just adds frustration to a machine you are still learning. Do a couple of low-stakes shots to get the feel, then work through it properly with how to dial in espresso and tick off the first-shot checklist when you are ready to chase quality.

The steam wand purge habit

If your machine steams milk, build one habit from the very first day, because it is far easier to start clean than to rescue a wand later. Purge the steam wand before and after every use. Before steaming, open the steam for a second to blow out any water sitting in the wand so you start with dry steam. After steaming, wipe the wand immediately with a clean damp cloth and open the steam again for a second to clear any milk drawn up inside. Milk that dries inside a wand bakes on and turns sour, and it clogs the tip — a new machine can develop a "wand not working" problem within weeks purely from skipped purges. Start the purge-and-wipe habit now and it becomes automatic; the fuller routine is in how to clean a steam wand.

What's normal on a new machine

A few things about a brand-new machine alarm people unnecessarily, so here is what is genuinely normal in the first days. A faint plastic or new-appliance smellon the first few runs is off-gassing from new components warming up for the first time, and it disappears within a handful of uses — the water flushes are largely what clears it. Priming noise the first time you run the pump, as it pulls water up an empty line, is normal, as is a change in pump sound once water is flowing steadily. Early shots tasting a little off is far more likely to be an undialled grind, a not-yet-flushed machine or stale coffee than a defect.

What is not normal is water leaking from the body, the machine failing to heat at all, error codes on the display, or a smell that is burning rather than merely plastic — those are worth stopping for and checking against the manual or the maker's support line. And on descaling: a new machine does not need descaling out of the box, but it is worth knowing the routine before the reminder ever appears, which is what how to descale an espresso machine is for. Beyond that, the fun part is building the little station around the machine — the grinder, scale, jug and tamper that make daily use smooth — which we lay out in setting up a home espresso bar.
