Coffee machine DeLonghi EC 685.W is a compact and functional solution for espresso lovers, which combines Italian build quality and an affordable price. The model belongs to the series Dedica, known for its minimalist design and the ability to make professional coffee at home. Despite its compact dimensions (only 15 cm wide), the device is equipped with a 15 bar pump, a stainless steel thermoblock and a fast heating system Thermoblock, which allows you to prepare espresso in 35-40 seconds.

This model is ideal for small kitchens or offices where saving space without losing the quality of the drink is important. Unlike more expensive analogues, EC 685.W does not have a built-in coffee grinder, but supports working with ground coffee and disposable capsules (using a special adapter). In the article we will analyze the technical characteristics, nuances of operation, as well as typical problems that owners encounter - from startup errors to pump repair.

Technical characteristics of DeLonghi EC 685.W

Model EC 685.W belongs to the class compact carob coffee machines with manual control. It is not equipped with automatic functions such as a cappuccino maker or programmable recipes, but it does offer complete control over the cooking process. Below are the key parameters of the device:

  • 🔹 Type: manual espresso machine
  • 🔹 Pressure: 15 bar (optimal for espresso)
  • 🔹 Power: 1300 W (fast heating)

Step-by-step instructions for making espresso

Espresso quality at EC 685.W depends on four key factors: coffee grinding, dose, rammer and extraction time. Let's break down the process step by step:

  1. Preparing coffee: use 7-9 g ground coffee per serving (for double holder - 14-18 g). The optimal grind is like fine sand. Grinding too fine can clog the filter, while coarse grinding can result in a weak drink.
  2. Tamping: distribute the coffee evenly in the holder and compact it with a spatula (tamper) with a force of ~15 kg. Insufficient tamping will result in uneven extraction.
  3. Holder installation: insert portafilter into the socket and turn to the right until it stops. Make sure it is tightly secured to prevent leaks.
  4. Starting extraction: click the button 1 cup or 2 cups. Optimal cooking time - 25-30 seconds for 30 ml espresso. If the coffee flows too quickly (less than 20 seconds), increase the dose or grind.

To check the quality of the extraction, pay attention to cream (foam on the surface of the espresso). The optimal cream has brindle color (light brown with dark veins) and lasts for at least 2 minutes. If the crema is too light or missing, the coffee is over-extracted or not compacted enough.

How to fix bitter taste in espresso?

Bitterness most often occurs due to overextraction. Try:

1. Reduce cooking time to 20-22 seconds.

2. Use a coarser grind.

3. Reduce the water temperature (switch to medium mode).

4. Reduce the dose of coffee by 1-2 grams.

If the bitterness persists, check the freshness of the coffee (it is best to use it within 2-3 weeks after roasting).

For cooking cappuccino or latte After extracting espresso, use a steam wand:

  1. Immerse the tube in cold milk (optimally 1/3 cup volume).
  2. Open the steam tap by turning the handle to the left.
  3. Hold the tip of the tube near the surface of the milk - this will create a vortex for even whisking.
  4. Close the tap when the milk temperature reaches 60-65°C (do not boil!).

Typical user mistakes and how to avoid them

Even experienced baristas sometimes encounter problems when working with DeLonghi EC 685.W. Here are the most common errors and how to fix them:

  • ❌ Coffee pours too quickly: The reason is insufficient compaction or too coarse grinding. Solution: Increase tamping force or grind finer.
  • ❌ The machine does not heat up: Check if the power light is on. If not, make sure the cord is firmly inserted into the outlet. If the indicator is flashing, the thermostat may be faulty.
  • ❌ Water leaking from under the holder: most often caused by loose fixation portafilter or wear of the rubber seal. Check the rubber band for cracks.
  • ❌ Steam wand does not work: the hole may be clogged. Clean it with a needle (included) and perform purge (short-term opening of steam without milk).
  • ❌ Coffee is bitter or sour: see spoiler above. Also check the freshness of the water - if the tank has not been washed for a long time, a foreign taste may appear.

Pay special attention steam wand care. After each use, wipe it with a damp cloth and blow with steam for 5 seconds to remove any remaining milk. If this is not done, the milkstone will clog the hole and the tube will stop working.

⚠️ Attention: Never operate the steam wand without milk or water for more than 10 seconds. This can lead to overheating and failure of the thermoblock.

Cleaning and maintenance: how to extend the life of your coffee machine

Regular Maintenance DeLonghi EC 685.W not only improves the taste of coffee, but also prevents breakdowns. The manufacturer recommends complete cleaning every 200-300 cycles (or once every 2-3 months with daily use). Basic procedures:

1. Daily care

  • 🧽 Rinse portafilter and a capsule holder after each use.
  • 💧 Rinse the water tank (especially if you use tap water).
  • 🧴 Wipe the case with a damp cloth (do not use abrasives!).

2. Weekly maintenance

  • 🧼 Clean the steam wand with a special brush (included).
  • 🔄 Pour 500 ml of clean water without coffee through the system (to remove oils).
  • 🔍 Check the rubber seal of the holder for wear.

3. Deep cleaning (once every 3 months)

To remove coffee oils and scale, use the product DeLonghi EcoDecalk or a similar solution based on citric acid. Instructions:

  1. Mix the product with water in a tank (the proportions are indicated on the package).
  2. Place the holder without coffee and start the cleaning cycle (press 1 cup and drain ~300 ml of solution).
  3. Repeat the process with clean water 2-3 times to rinse.
  4. Wipe all removable parts with a dry cloth.

Critical information: If you ignore descaling, the thermoblock may fail in 1-2 years. In regions with hard water (>8 mEq/L) It is recommended to use filtered or bottled water.

Problem Reason Solution
The machine does not turn on Thermostat or fuse is faulty Check the fuse (in the plug) or contact service
Weak water pressure The filter or tubes are clogged Clean the system EcoDecalk or rinse under running water
Extraneous noise during operation Pump wear or air ingress Pump the water without coffee 2-3 times
Unstable temperature Thermoblock malfunction Diagnostics required at a service center

Common faults and repairs

Despite the reliability DeLonghi EC 685.W may break due to improper use or wear of parts. Below are typical breakdowns and how to fix them.

1. The machine does not heat the water

If the power light is on but the water remains cold, the problem may be:

  • 🔌 Thermostat: check the resistance with a multimeter (should be ~50 ohms). If the circuit is broken, replacement is required.
  • ☕ Thermoblock: if the heater burns out, you can replace it yourself (the part costs ~3000-4000 rubles).
  • ⚡ Fuse: There is a 250V thermal fuse in the power plug - check its integrity.

2. Water leak

Most often caused by:

  • 🛠️ Wear of the sealing rubber: replace with a new one (part number DeLonghi 5103217201).
  • 🔧 Crack in the tank: If the plastic breaks, the tank must be replaced.
  • 💧 Loose fitting of tubes: check the connections inside the housing (disassembly required).

3. The pump does not work

If the coffee does not flow when you press the button and the pump does not hum:

  • 🔊 Check if the filter in the holder is clogged.
  • 🔌 Make sure that the pump contacts are not oxidized (cleaned with alcohol).
  • 🛒 If the pump has a mechanical breakdown (cost ~2500 rubles), it is easier to replace it than to repair it.
⚠️ Attention: When disassembling the housing, unplug the machine and drain all water from the system. Inside there are high voltage elements (capacitors) that can store a charge.

To replace parts, it is recommended to use original spare parts DeLonghi. For example, a rubber seal for the holder (gasket) costs ~500 rubles, and a new one portafilter — ~1500 rub. In Moscow and St. Petersburg, service centers offer diagnostics for ~1000 rubles, and repair of a pump or thermoblock costs 3000-6000 rubles.

Comparison with analogues: which is better to choose?

If you are considering DeLonghi EC 685.W as an option for purchase, it is worth comparing it with the main competitors in the segment up to 25,000 rubles:

Model Price (2026) Pros Cons

💡

When purchasing on the secondary market, give preference to machines with a receipt and warranty card - this confirms that the device has not been subjected to unqualified repairs.

FAQ: answers to frequently asked questions

Can capsules be used in DeLonghi EC 685.W?

Yes, but you will need to purchase capsule adapter (for example, DeLonghi ESE Pod Adapter). It is installed instead of a standard filter in a holder. Please note that a pressure of 15 bar may burst thin capsules - only use compatible carob machines (e.g. Illy Iperespresso).

What coffee grind is suitable for this model?

Optimal grinding - medium-fine (like granulated sugar). A grind that is too fine can clog the filter, while a grind that is too coarse can result in weak and watery espresso. If you don't have a coffee grinder, buy ground coffee marked "for espresso" (for example, Lavazza Qualità Rossa or Jardin Gourmet).

Why does the machine make loud noises when operating?

The noise may be caused by:

  • 🔊 Air in the system: pump the water without coffee 2-3 times.
  • 🛠️ Pump wear: If the sound is similar to grinding, it will need replacement.
  • 💧 Low water level: add water to the tank.

If the noise does not disappear, contact service.

How often should the rubber seal be changed?

Rubber service life (gasket) — 6-12 months with daily use. Signs of wear:

  • Water leaking from under the holder.
  • Cracked or deformed elastic band.
  • Uneven extraction (coffee flows around the edges).

Replacement takes 5 minutes and costs ~500 rubles. (original part DeLonghi 5103217201).

Can I use tap water?

Technically yes, but not recommended. Hard water accelerates the formation of scale, which shortens the life of the thermoblock. Optimal options:

  • 💧 Filtered water (for example, through Barrier or Aquaphor).
  • 🚰 Bottled water with low hardness (<4 mEq/L).
  • 🧪 Use water softeners (for example, DeLonghi DLSC002).
