Espresso machine Adler AD 4390 1350W – single-unit domestic coffee maker (damaged packaging)

The Adler AD 4390 is a compact domestic espresso machine with 1350 W power and a fast thermoblock heating system that reaches brewing temperature in about 20 seconds. It offers five functions—single espresso, double espresso, americano, cooled espresso and milk frothing—controlled from an LCD touch panel with PID temperature regulation for stable extraction and consistent crema. The unit has a stainless steel housing, removable 1.5 l transparent water tank with foldable handle, heated cup plate and safety features such as overheating and overpressure protection plus automatic shut-off after 10 minutes.

Advantages

The machine combines rapid heating, PID-controlled temperature stability and a 20-bar working pressure to deliver consistent espresso extraction and rich crema. A milk frothing system and steam regulation allow preparation of milk-based drinks, while the removable parts—water tank, drip tray and grid—simplify cleaning. The stainless steel exterior and heated cup plate add practicality for everyday home use.

Suitable for

• Home users who want single-serve espresso and basic milk-based drinks
• Small apartments or home kitchens with occasional coffee preparation
• Users who value quick heat-up and stable brewing temperature

When it may not be suitable

This model is intended for domestic use and may not meet the demands of busy cafés or high-volume commercial environments. It provides basic milk frothing and temperature control but lacks the capacity and advanced commercial features required for professional barista workflows.

How to use

Fill the removable water tank and switch on the machine using the LCD touch controls.

Use the supplied portafilter and chosen filter basket for one or two shots, tamp the grounds with the included tamper, attach the portafilter to the group head and start extraction. For milk drinks, use the milk frothing system and steam regulation to texture milk to the desired consistency. After use, remove the drip tray and grid for cleaning and refill or empty the tank as needed.

What to consider before purchase

• Item listing notes damaged packaging; check packaging condition if that is important
• Requires a standard 220–240 V, 50 Hz power supply

Usage recommendations

Use freshly ground coffee and the correct single- or double-shot filter basket for best extraction. Preheat cups on the heated plate and purge the steam wand briefly before frothing milk. Regularly descale and clean removable parts to maintain performance.
