Advantages and disadvantages of the model
Like any technology, De’Longhi Dedica EC685 has its pros and cons. Let's look at them in detail so that you can objectively assess whether this car is right for you.
| Benefits | Disadvantages |
|---|---|
| 🔹 Compact size - takes up little space in the kitchen. | ⚠️ Plastic body (although durable, but less premium to the touch). |
| 🔹 Fast heating (35–40 seconds to operating temperature). | ⚠️ There is no automatic shutdown - you need to monitor the operating time. |
| 🔹 13 grinding levels - allows you to experiment with taste. | ⚠️ Noisy operation of the coffee grinder (about 80 dB). |
| 🔹 Possibility to use ground coffee (there is a workaround for filling without a coffee grinder). | ⚠️ There is no built-in cappuccino maker - the foam is prepared manually or with a separate device. |
| 🔹 Easy cleaning - removable parts are washed under running water. | ⚠️ Requires regular decalcification (once every 1-2 months with hard water). |
One of the key advantages EC685 is her versatility: The machine is suitable for both beginners (due to simple controls) and experienced users (due to manual adjustment of grinding and pressure). However, the lack of an automatic cappuccino maker may disappoint latte lovers - to froth milk you will have to buy a separate steamer or use a French press.
One more nuance - thermoblock. On the one hand, it provides fast heating, on the other hand, it is less stable in maintaining temperature compared to boiler systems. This means that the perfect espresso may require additional adjustments (such as preheating the holder).
⚠️ Attention: If you are using De’Longhi Dedica EC685 In an office or high traffic area (more than 10 cups per day), be prepared to clean and replace O-rings more frequently. The thermoblock wears out faster under such conditions.
Switching on and setting up the coffee machine for the first time
Before first use De’Longhi Dedica EC685 There are several mandatory steps that need to be completed. This will help avoid breakdowns and ensure proper operation of the device.
Rinse the water reservoir with warm water|Install the filter into the holder and rinse it without coffee|Run 2-3 cycles of hot water to clean the system|Adjust the grind degree (for espresso, usually 5-7)|Check the tightness of all connections-->
After preparation, you can start setting up:
- Setting the grinding degree. For espresso it is recommended to start with
Level 6–7(out of 13 possible). If the coffee flows too quickly, reduce the grind; if it is slow, increase it. - Tamping coffee. Use a measuring spoon with a press to press the coffee evenly into the holder. The pressing force should be medium - too weak a tamp will lead to a weak drink, too strong - to over-extraction.
- Warming up the holder. Before brewing, run hot water through an empty holder (without coffee) for 5-10 seconds. This stabilizes the temperature.
- Extraction time control. The ideal time for 30ml espresso is 25-30 seconds. If the drink flows faster or slower, adjust the grind or amount of coffee.
Please note indicators on the control panel:
- 🔴 Red LED - The car is heating up.
- 🟢 Green LED - ready to go.
- 🟡 Yellow flashing — decalcification or filter replacement is required.
Typical faults and solutions
Even with careful use De’Longhi Dedica EC685 may fail. Let's look at the most common problems and their solutions.
1. The coffee machine does not heat the water
If the heating indicator does not light up when turned on or the water pours out cold, the reasons may be the following:
- 🔌 Eating problems: Check the outlet, cord and plug. Try connecting the machine to a different power source.
- 🔥 Thermal fuse has blown: located next to the thermoblock. Requires replacement (part can be found at art. no.
C00089683). - 🧊 The thermoblock is clogged with scale: deep cleaning or decalcification with a special agent is necessary (for example, De’Longhi EcoDecalk).
- 📉 Temperature sensor faulty: If the car turns on but does not heat up, the thermostat may be faulty. Diagnosis requires disassembly.
2. Weak water pressure or coffee flows in a thin stream
This problem is usually associated with:
- ☕ Clogged filter holder: rinse it under running water or replace it with a new one (art.
DLSC002). - 🔄 Worn o-ring: located in the holder. If damaged, requires replacement (art.
C00089684). - 💦 Low water level in the tank: Add water and make sure the supply tube is not kinked.
- ⚙️ Incorrect tamping of coffee: Packing too tightly blocks the flow of water. Try decreasing the pressure.
3. The car is leaking
Leaks can occur in several places:
- 🚰 From under the holder: Check the integrity of the O-ring and its correct installation.
- 💧 From a water tank: Make sure it is firmly inserted into the grooves. If the leak continues, the tank itself may be cracked (needs replacement).
- ☕ From under the drip tray: Liquid collection container is full. Empty it and rinse it.
⚠️ Attention: If the leak does not stop after cleaning and replacing consumables, do not use the machine - this may lead to a short circuit. Contact the service center De’Longhi or to a trusted specialist.
Diagnosing complex faults (e.g. electronics) may require multimeter. Use it to check:
- Heating element resistance (must be within
20–40 Ohm). - The voltage on the control board (must match
220–240 V). - Integrity of wires and contacts.
How to disassemble De’Longhi Dedica EC685 for diagnostics?
To access internal parts:
1. Unplug the machine and drain the water.
2. Remove the drip tray and water tank.
3. Unscrew the 4 screws on the bottom panel (a Phillips screwdriver is required).
4. Carefully remove the top cover, starting from the back.
5. To access the thermoblock, unscrew 2 more screws on the rear wall.
⚠️ Be careful - there may be sharp edges and hot elements inside!
Decalcification and maintenance of the coffee machine
Regular cleaning De’Longhi Dedica EC685 - the key to her long service. This is especially true decalcification (descaling), since the thermoblock is sensitive to hard water. The manufacturer recommends performing the procedure every 1–2 months (depending on frequency of use).
For decalcification you will need:
- 🧴 Special product (for example, De’Longhi EcoDecalk or Urnex Dezcal).
- 💧 1 liter of clean water.
- ⏱️ 30–40 minutes of free time.
Step by step instructions:
- Turn off the machine and drain any remaining water from the reservoir.
- Prepare the solution: mix the descaling agent with water in the proportion indicated on the package (usually
1 package per 1 l). - Pour the solution into the reservoir and turn on the machine.
- Start the coffee cycle without a holder (simply press the espresso button). Let half of the solution pass through, then turn off the machine for 15 minutes.
- Repeat the cycle, draining the remaining liquid.
- Rinse the system 2-3 times with clean water, passing it through the thermoblock.
In addition to decalcification, do not forget about daily care:
- 🧽 Rinse the holder and filter after each use.
- 🧹 Clean the coffee grinder millstones with a brush (included) once a week.
- 🗑️ Empty the waste coffee container and drip tray.
Using filtered or bottled water reduces the frequency of decalcification by 2–3 times and extends the service life of the thermoblock.

FAQ: answers to frequently asked questions
Can I use ground coffee instead of beans in the De’Longhi Dedica EC685?
Yes, but for this you need:
- Turn off the coffee grinder (press and hold the grind button for 5 seconds).
- Pour ground coffee into the holder (dosage - 7 g for 1 cup, 14 g for 2).
- Use a measuring spoon to tamp down the coffee.
Please note: the grind level should be espresso (fine, like powder). Grinding too coarsely will result in a weak drink.
Why does the machine make loud noise when working?
Noise can occur for several reasons:
- 🔊 Coffee grinder operation - this is normal, since the millstones are ceramic. Noise level is about 80 dB.
- 💦 Air in the system: If the machine has not been used for a long time, run 1-2 cycles of hot water without coffee.
- ⚙️ Pump wear: If the noise is accompanied by weak pressure, the pump may need to be replaced.
If the noise appears suddenly, check to see if a foreign object has entered the grinder.
How to increase the strength of espresso?
Strength depends on several factors:
- ☕ Coffee dosage: Try increasing the amount from 7g to 8-9g per 30ml drink.
- ⏱️ Extraction time: Ideal time is 25-30 seconds. If the coffee flows faster, reduce the grind.
- 🌡️ Water temperature: Warm up the holder before use (run hot water through it for 5-10 seconds).
The freshness of the beans also affects: for espresso it is better to use coffee roasted no more than 3-4 weeks ago.
What to do if the machine does not turn on?
Check the following:
- 🔌 Food: Make sure the plug is firmly inserted into the outlet and there is power.
- 🔋 fuse: On some models it is located on the power cord. Check its integrity.
- 📱 Power button: Sometimes the contacts oxidize. Try pressing the button several times.
- ⚡ Thermal fuse: If the car overheated, it could work. Replacement required (art.
C00089683).
