This is the standard for home carob coffee makers, allowing you to break through the coffee tablet and extract maximum flavor. System cappuccinatore allows you to whip milk foam for cappuccino and latte.
The set usually comes with a double holder (horn), which allows you to prepare one or two cups at the same time.

The energy saving system deserves special attention. After 9 minutes of inactivity, the coffee maker automatically goes into sleep mode. This helps save energy and reduces wear on the heating element during long periods of inactivity.
Coffee making process: step-by-step instructions
To get a delicious drink, it’s not enough to just press a button. It is necessary to follow the cooking technology. First, warm up the cups and the cone itself by running some hot water through it. This will prevent the espresso from cooling down suddenly when it comes into contact with cold walls.
Then pour the ground coffee into the filter. For a double horn, the optimal dosage is 14-18 grams, depending on the type of grain and degree of roasting. Tamping (tempering) must be uniform and strong enough so that water passes through the tablet with the required resistance.
☑️ Checklist before launch
Insert the cone into the group and immediately press the cook button. Do not wait too long, otherwise the coffee may burn due to the temperature of the group. The pour time for a double espresso should be around 20-25 seconds. If the water flows too quickly or too slowly, you need to change the grind level.
⚠️ Attention: Never leave coffee in the cone after preparation. Remaining moisture and oils quickly oxidize, which spoils the taste of the next cup and can lead to souring of the channels.
To prepare cappuccino, use the panarello, a special attachment on the cappuccino maker. Dip the spout into cold milk and release the steam. After whipping, be sure to briefly purge the steam wand with steam to clear it of any remaining milk.
Typical problems and solutions
During operation, users may encounter a number of typical situations. For example, the coffee may flow too quickly, indicating the grind is too coarse. Conversely, if the liquid drips drop by drop, the grind is too fine or the tablet is over-compacted.
Sometimes a problem occurs when the decalcification indicator lights up prematurely. This may occur due to the use of high hardness water or an electronic failure. In this case, you can try resetting the counter through the service menu or performing a cleaning cycle.
- 🔇 Noisy operation is normal for a vibration pump.
- 💧 Water leaking under the horn - check the cleanliness of the rubber seal.
- 🌡️ Insufficient temperature - let it warm up for 5-10 minutes.
- 🚫 Doesn’t turn on - check the tightness of the water tray.
If the coffee maker DeLonghi EC 685 starts to leak from above, check whether the horn is installed evenly. Often the reason lies in the contact of coffee particles with the group's o-ring. Regular cleaning of this element with a soft brush solves the problem in 90% of cases.
Care and maintenance: decalcification and cleaning
Regular maintenance is the key to a long life for your coffee maker. The main procedure is decalcification. Hard water causes scale to form inside the thermoblock, which reduces heating efficiency and can lead to failure. The manufacturer recommends carrying out this procedure every 2-3 months.
For cleaning, use special products based on lactic or citric acid. Pour the solution into the reservoir, turn on the decalcification mode (by holding down the corresponding button) and follow the instructions on the indicators. The process takes about 20-30 minutes.
Don't forget to wash the removable parts too. The tray, grill and water tank should be washed with warm water and a mild detergent once a week. This will prevent the appearance of mold and unpleasant odors.
⚠️ Attention: It is strictly forbidden to use acetic acid or aggressive chemicals for decalcification. They can damage the internal rubber seals and the plastic tank.
Once every six months, it is recommended to lubricate the group’s O-ring with food-grade silicone. This will maintain the elasticity of the rubber and ensure a tight connection. Also check the condition of the mesh in the horn - if the holes are clogged, they can be cleaned with a thin needle or soaked in a special solution.
Regular decalcification using special means is the only way to avoid costly repairs of the thermoblock in the future.
Comparison with competitors and final conclusions
There are many analogues on the market, such as models from Gaggia or Philips. However DeLonghi EC 685 BK wins due to the combination of price, build quality and compactness. The metal body sets it apart from plastic competitors in this price segment.
Of course, this coffee maker will not replace a professional machine that costs thousands of dollars. But for the coffee lover who wants better results than 3-in-1 bags, this is a great place to start. It is easy to learn and does not require complex settings.
In conclusion, we can say that the model EC 685 has established itself as a reliable "working" device. With proper care, it will last for several years, delighting you with aromatic espresso every morning. The main thing is not to ignore the requirements for water quality and regular cleaning.
Can I use ground coffee from the store?
Yes, you can. However, coffee in vacuum briquettes is often too finely ground (“to dust”), which can lead to over-extraction and bitterness. It is better to buy fresh coffee and grind it just before brewing.
Why does the coffee turn out cold?
Most likely, you did not warm up the cups and group. The thermoblock heats water quickly, but the metal parts of the coffee maker cool down. Always run 50ml hot water through an empty horn before brewing.
How often should the filter in the spout of the cone be changed?
Filters (grids) do not have a strict expiration date. They are replaced only when they wear out or if they become clogged and cannot be cleaned. This usually happens once every 1-2 years of active use.
