To descale your DeLonghi coffee machine, follow these general steps. Always refer to your model’s manual for specific instructions, as details may vary:
Materials Needed:
DeLonghi descaling solution (or a manufacturer-approved alternative).
Fresh water.
A container for wastewater.
Step-by-Step Guide:
1. Prepare the Machine:
Turn off the machine, unplug it, and let it cool.
Empty the water tank, drip tray, and coffee grounds container.
2. Add Descaling Solution:
Fill the water tank with the descaling solution mixed with water as directed on the product label (usually 1:1 with water). Do not use vinegar unless specified by DeLonghi.
3. Enter Descaling Mode:
Plug in and turn on the machine.
Activate descaling mode:
Many models: Press and hold the power button for 5–10 seconds until lights blink or the descale indicator activates.
Some models: Press specific buttons (e.g., steam + power). Check your manual for the correct combination.
4. Run the Descaling Cycle:
Place a large container under the coffee spout and steam wand.
Start the cycle (follow machine prompts). The solution will flow through the internal pipes, coffee outlet, and steam wand.
Pause halfway if instructed (to let solution dissolve scale), then resume.
5. Rinse Thoroughly:
Empty and rinse the water tank.
Refill with fresh water and reattach.
Run multiple water cycles (via brew button or descaling prompts) until the tank is empty. Repeat rinsing 2–3 times to remove all solution residue.
6. Reset the Machine:
If your model has a descale indicator light, it should turn off automatically. If not, manually reset it (e.g., press and hold a button as specified in the manual).
7. Final Checks:
Wipe down external parts and rinse removable components (drip tray, water tank).
Run a test brew with fresh water to ensure no descaling solution remains.
Important Tips:
Frequency: Descale every 1–3 months, depending on water hardness and usage.
Safety: Never leave descaling solution in the machine for extended periods.
Manual: Always consult your model’s manual for exact instructions (available on DeLonghi’s website if lost).
By following these steps, you’ll maintain your machine’s performance and longevity. ☕✨
