How Does an Espresso Maker Work?

 Espresso Maker Repair

An espresso maker brews coffee with steam instead of hot water, though many units can do both.

A home espresso maker is a small appliance for brewing coffee beans using steam rather than hot water. An electric steam-pressure espresso maker heats water, forcing the resulting steam through a filter basket filled with finely ground dark-roast coffee beans. Higher quality espresso makers also have pumps. In addition to espresso, many units can make cappuccino (espresso topped with steam-frothed milk) and latte (espresso mixed with steam-heated milk) beverages.

What Can Go Wrong with an Espresso Maker?

A simple espresso maker is similar in operation to a Coffee Maker; many of the same things can go wrong with it. Electrical cords, switches, the heating element, thermostat, and fuse can all fail. In addition, the pressure gasket can be damaged or the safety plug may have opened, and the steam tube or frother can become clogged.

Fix-It Tip

Make sure you clean an espresso maker after each use by rinsing or washing the filter basket parts and steam nozzle. If your unit has a frother assembly, allow steam to escape into a water-filled frothing pitcher for a few seconds after use, then wipe the tube and frother with a damp cloth.

How Can I Identify an Espresso Maker Problem?

  • If the espresso maker does not work, make sure power is on at the outlet and test the electrical cord. Also test the switch and the thermostat (see the Appliance Controls Fix-It Guide), the fuse, and the heating element, servicing or replacing as needed.
  • If no espresso drips from the filter cup, the grounds may be too fine or tamped too hard.
  • If the espresso comes out too quickly and is weak, make sure you use the proper grind and the correct amount of water, usually recommended as 1/4 cup per 2 tablespoons of coffee.
  • If the espresso spurts from around the filter cup, inspect and clean the filter cup. Make sure that the filter basket assembly seats completely. Also verify that you are using the correct ratio of coffee and water. Remove and replace gasket as needed.
  • If the espresso is not hot, test the heating element and thermostat.
  • If the espresso maker makes little or no steam, turn the unit off and let it cool, then disassemble and clean the frother and the steam tube.

Fix-It Tip

Mineral deposits can easily build up and block passages in espresso makers. Use distilled or filtered water if possible. Also clean the espresso maker periodically, following the manufacturer’s recommendations.
