Using an espresso machine involves nine steps: heating, filling the water tank, grinding, dosing, tamping, locking the portafilter, brewing, and cleaning the steam wand.
Whether you unboxed your first semi-automatic or inherited a commercial-style model, the routine behind a proper espresso shot is the same. You are heating water and forcing it through finely ground coffee at high pressure — and the window between a bitter, thin shot and a syrupy one is narrower than you think. These steps walk you through the full workflow, from switching the machine on to wiping down the steam wand.
Preheat the Machine and Fill the Tank
Turn the machine on and give it time to heat. Flashing lights on many models mean the unit is still warming up; wait until they go solid before you pull a shot. Skipping this step is the most common reason a first shot tastes sour — the water never reached brewing temperature.
While it heats, fill the water tank with fresh water. Overfilling can cause water to pool where it shouldn’t.
For machines with a steam wand, this preheat matters twice. You will use that wand after brewing, and it needs the boiler fully hot to produce dry steam rather than sputtering water.
Grind, Dose, and Tamp the Coffee
Espresso demands a fine grind — finer than drip coffee, with a texture like table salt. If you bought pre-ground beans, they work, though they lose aroma quickly once the bag opens.
Dose into the portafilter basket according to its size. A standard double basket holds 14 to 21 grams; a 2:1 ratio is a dependable target, meaning 18 grams of coffee should yield about 36 grams of liquid espresso in the cup. The grounds should sit level in the basket before you tamp.
Tamp evenly, pressing straight down so the coffee surface is flat and level. Press firmly but not with maximum force — a general espresso guide emphasizes that coffee should be pressed evenly and not too firmly. An uneven tamp creates channels where water rushes through thin spots, which leaves the shot weak and sour.
Lock In, Brew, and Watch the Timer
Lock the portafilter into the group head — the metal fitting under the machine’s brew unit — and place a warm cup under the spout. If your machine has a purge function, run a quick flush of water through the empty group head first to stabilize temperature.
Press the espresso or shot button to start extraction. The ideal shot runs 25 to 30 seconds from the moment water hits the grounds. If your machine does not stop automatically, press the button again when the cup holds the volume you want — roughly 2 ounces for a double shot.
The pour should start dark and slow, then bloom into a golden-brown crema. If it runs fast and pale, your grind is too coarse; if it drips or stalls, the grind is too fine. Dialing the grinder is the single biggest upgrade you can make to your shots.
Froth Milk, Then Clean Everything
Brew your espresso before steaming milk — guides advise not leaving coffee sitting in the brew handle while the wand works. To steam, submerge the wand tip just below the milk’s surface, open the steam valve, and keep the tip near the surface to stretch the milk before sinking it deeper to heat.
After steaming, purge the wand briefly and wipe its exterior with a soft damp cloth. KitchenAid’s semi-automatic manual explicitly directs this wipe-down; milk residue that dries onto the wand is the fastest way to ruin its performance. If you frothed milk first by mistake, the machine may need a full cool-down cycle before it will brew again.
Knock out the used puck, rinse the portafilter, and wipe the drip tray area. The entire cleanup takes under two minutes.
Machine Support Varies by Brand
When something does go wrong, contact the manufacturer directly. The two lines exist because the brewing systems are entirely different, so check your model number before dialing.
If you would rather skip manual dosing entirely, an automatic model handles grinding, tamping, and milk frothing at the push of a button. Our tested roundup of the best automatic espresso machines compares the top options if you are ready to upgrade.
FAQs
Why is my espresso dripping instead of flowing?
Your grind is too fine, or you tamped too hard, which packs the coffee so densely that water cannot push through. Adjust the grinder one step coarser and try again. If you are using pre-ground coffee, a coarser blend may be needed.
How long should a double shot take to brew?
Aim for 25 to 30 seconds from the moment water hits the grounds. Faster pours produce weak, sour shots, while slower ones taste bitter and over-extracted. Timing your shot is the most reliable way to judge whether your grind and dose are correct.
Do I need to clean the steam wand after every use?
Yes. Purge the wand to clear milk from inside, then wipe the exterior with a damp cloth immediately after steaming. Dried milk clogs the tip and harbors bacteria, and a blocked wand produces weak steam the next time you use it.
