What You’ll Need:

- A container to collect water (large enough to hold at least 1 liter)
- Clean water
Step-by-Step Descaling Process
Step 1: Prepare the Machine
- Switch the coffee machine off and unplug it from power.
- Remove the water tank and drain any remaining water.
- Clean the water tank thoroughly to remove any residue.
Step 2: Add Descaling Solution
- The water tank can be filled with fresh water, to a level given by your machine’s user manual.
- Fill the water tank with water, adding the recommended quantity of DeLonghi Descaler solution. (Refer to the instructions on the descaler bottle.)
- Reinsert the water tank into the machine.
Step 3: Start the Descaling Process
- Place a container under the coffee spout and steam wand (if your machine has one) to collect the descaling solution.
- Turn the machine on and access the descaling mode:
- For automatic models: Press the descaling button or follow the descaling sequence as indicated in the user manual.
- For manual models: Follow the steps for activating the descaling function.
- The machine will start dispensing the descaling solution through the spout and steam wand. Allow it to run until the tank is empty.
Step 4: Rinse the System
- Once the descaling cycle is complete, empty the container used to collect the descaling solution.
- Rinse the water tank thoroughly to remove any residual descaler.
- Fill the tank with fresh water and run a rinse cycle:
- Turn the machine on and allow it to dispense the clean water through the spout and steam wand until the tank is empty.
Step 5: Final Steps
- Repeat the rinse process if necessary to ensure all traces of the descaling solution are removed.
- Wipe the exterior of the machine with a damp cloth.
- Refill the water tank with clean water for your next use.
- Resume normal operation.
Tips for Optimal Maintenance
- Frequency: Descale your machine every 1–3 months, depending on water hardness and usage.
- Use Filtered Water: This can reduce the buildup of limescale and extend the time between descaling cycles.
- Monitor Alerts: Many DeLonghi machines have descaling alerts. Follow these to ensure timely maintenance.
By following this procedure, your DeLonghi coffee machine will continue to deliver perfect coffee every time!
