Setup means washing removable parts, filling the correct reservoir with fresh cold water, and running a water-only cycle before the first real brew.
Skip the wash and rinse cycle and your first cup tastes like plastic and metal dust. An all-in-one coffee and espresso machine packs two brewing systems into one footprint, each with its own reservoir, filter, and warm-up behavior. Get the order right once and every cup after is repeatable.
What Comes Out of the Box and What Gets Washed First
Unbox completely, then wash every removable part in warm soapy water before it touches coffee. Combo machines ship with packing tape, foam inserts, and loose hardware — check everything against the manual’s accessory list.
- Remove all tape, foam, and protective film — including the strip over the drip tray and any shipping clip on the portafilter holder.
- Wash the portafilter, filter baskets, drip tray, carafe, and water reservoirs in warm soapy water, then rinse and dry fully.
- Wipe the exterior with a damp cloth; never submerge the base unit.
Two accessories decide everything downstream: the espresso filter basket and the drip-side filter. Both must be seated correctly.
Where to Place the Machine and How to Fill It
Set the unit on a flat, stable, dry, heat-resistant counter with open space for ventilation. The De’Longhi COM532M support page and Ninja’s CFN600 documentation both stress clearance — these machines vent heat and steam, and a cabinet pressed against the top traps both.
Fill with fresh, cold drinking water. Not hot, not distilled, not leftover from the kettle. Most combo units run two reservoirs: one feeds the drip carafe, one feeds the espresso side. Check which you’re filling before you pour. Stop at the MAX line — overfilling pushes water past the valve.
| Setup Step | What To Watch For | Common Failure |
|---|---|---|
| Wash removable parts | Warm soapy water, full dry | Leaving film residue on baskets |
| Place the unit | Flat, heat-resistant, ventilated | Cramming under a cabinet |
| Fill reservoir | Fresh cold water to MAX line | Filling the wrong reservoir |
| Power on and heat | Ready light goes steady | Brewing during warm-up |
| Water-only rinse | Discard the first cycle | Skipping the prime entirely |
| Drip-side prime | No grounds in the filter | Running a cycle with old grounds |
| Espresso-side prime | Empty basket, locked portafilter | Loose portafilter leaking |
Priming the Espresso Side
Power on, let the machine heat fully, and run at least one water-only cycle through each side before any coffee goes in. The espresso indicator blinks during warm-up and turns steady when ready — brewing before that steady light is a common first-week mistake. If you’re comparing combo units, our roundup of all-in-one coffee and espresso machines covers which models separate the reservoirs.
- Insert the correct filter basket — small for single, larger for double.
- Add finely ground espresso and tamp firmly and level. Coarse or pre-ground drip coffee will channel and run watery.
- Lock the portafilter into the group head until it seats. An unlocked portafilter sprays water sideways.
- Place a cup under the spout and start the brew once the ready light is steady.
- Stop the shot manually when the target volume is reached — most combo machines don’t auto-stop on the espresso side.
Discard that first run. The initial water-only cycle flushes internal components and clears manufacturing residue; both De’Longhi and Ninja treat it as required, not optional.
Priming the Drip Side and Reading Error Lights
Insert the drip filter and carafe, fill the drip reservoir, and run one brew cycle with no grounds. Ninja’s CFN600 FAQ lists one troubleshooting clue worth knowing up front: if the brewer keeps showing “Add Wtr” after you’ve filled the reservoir, the fix isn’t more water — contact Ninja customer service, because the sensor or line needs attention.
Once both sides have run a clean water cycle, load fresh grounds, brew, and adjust grind and tamp from there.
FAQs
Do I really need to run a water-only cycle before the first cup?
Yes. Both De’Longhi and Ninja setup documentation include an initial water-only cycle, and skipping it leaves manufacturing residue in the brew path. Discard that first run, then brew normally on the second pass.
Why does my combo machine have two water reservoirs?
Because the drip and espresso sides brew differently and draw water separately on most combo models. One reservoir feeds the carafe, the other feeds the group head. Filling the wrong one produces a machine that powers on but won’t brew on the side you’re using.
How do I know when the espresso side is actually ready?
The espresso indicator blinks while heating and turns steady when ready to brew. Starting a shot before that gives a lukewarm, underextracted result — the most common early mistake with these machines.
