How to Use a Combination Coffee Maker | Drip and Espresso Basics

Combination coffee makers pair a full drip brewer with an espresso machine in one countertop unit. They save space and let you switch between a morning pot of coffee and a proper espresso shot without owning two appliances. The key is understanding that each side operates independently, with its own water supply, filter basket, and controls — and most models let you run them at the same time.

The Basic Operating Steps

Every combination machine follows the same four-step rhythm. Get this right and you can handle nearly any model:

• Fill the correct reservoir. The drip side and espresso side usually have separate water tanks. Check which one you are filling before you pour.
• Load the right coffee format. Ground coffee goes in the drip filter basket; ground espresso or a pod goes in the portafilter on the espresso side.
• Position the carafe or cup. The glass carafe sits on the warming plate for drip. Espresso cups go under the spouts.
• Start the brew. Press the appropriate button for the side you are using.

On most units the two systems run separately, but some models support simultaneous brewing so you can pull a shot while the pot fills.

Using the Drip Side

The drip side works like a standard coffee maker. Fill the reservoir with fresh, cold water to the cup markings, then insert a paper filter or the machine’s reusable gold-tone filter into the basket. Add ground coffee and place the carafe on the warming plate. Press the Coffee ON/OFF button to start brewing.

Most combination models add useful options. On the De’Longhi COM532M, pressing the BOLD button before brewing produces a stronger cup. The same machine includes HOUR/MIN and AUTO controls for delayed brewing — set the timer the night before and wake up to fresh coffee.

Using the Espresso Side

The espresso side demands a little more care than the drip side. Start by filling the espresso reservoir with water, then insert the single, double, or pod basket into the portafilter. If you are using grounds, add finely ground espresso and tamp firmly — a loose puck gives you watery, sour shots.

Lock the portafilter into the brew head, place a cup under the spouts, and press the Espresso ON/OFF switch. Select the espresso button to start the extraction. The shot should flow in a slow, honey-like stream. If it gushes, your grind is too coarse or you skipped the tamp.

A few models include a steam wand for milk. Place the wand just below the surface, open the steam knob, and move the pitcher up and down until you hit the texture you want, then close the knob.

Maintenance and Common Mistakes

Most brewing failures trace back to three causes: low water, a clogged filter, or scale buildup. Always check the reservoir before you start. Clean the reusable filter and portafilter after each use. Run the descaling cycle when the manual calls for it, using only the approved descaling solution where the manufacturer specifies one.

Two mistakes matter most on the espresso side. First, never use coarse drip grind in the portafilter — the water will rush through and produce a weak shot. Second, do not skip the tamp. The manual for the COM532M and other models is clear that firm pressure is required for proper extraction. On the drip side, the main error is overfilling the basket; use the scoop that came with the machine rather than guessing.

Filter compatibility varies by model. Some machines take paper filters, others use gold-tone permanent baskets, and some accept both. The espresso side may take single, double, or pod baskets depending on the unit, so check your model’s manual before buying accessories.
