- Access the descaling menu by pressing and holding the OK button, then select "Descale" under "Maintenance."
- Ensure the drip tray is empty and clean before confirming the descaling process, which cannot be canceled once started.

Descale Preparation Steps

First, fill the water container with lukewarm water up to the specified mark. If you have a built-in coffee machine from the CVA series, use two descaling tablets. For countertop models in the CM series, one tablet suffices. Regular descaling is recommended every 1-3 months depending on water hardness. Be careful while mixing; avoid spilling the descaling solution to prevent damage to your surfaces or floors.
Descale Safety Precautions
Regular descaling is essential to maintain your machine's performance. Always use Miele descaling tablets, as other substances can harm your coffee machine. Make certain to descale in a well-ventilated area to avoid inhaling fumes. Mineral buildup prevention helps maintain optimal coffee quality and machine performance.
Descale Solution Preparation
Dissolve the tablets in lukewarm water—cold water won't dissolve them fully, while hot water could damage the boiler. After descaling, use a clean microfiber cloth to wipe the reservoir and eliminate any residue. Finally, turn off the machine and confirm it's cool before accessing the descaling menu. Following these steps sets the stage for a successful descaling process.
Descaling Process Instructions
To initiate the descaling process for your Miele coffee machine, press and hold the OK button until the MENU appears on the display.
Once you see the menu, use the arrow sensors to select "Maintenance" and press OK.
Next, choose "Descale" from the options displayed. Confirm your selection by pressing OK again.
After this, the descaling process will begin, and you won't be able to cancel it once it's started.
Now, the machine will prompt you to empty the drip tray. Make sure it's clean before moving on.
Fill the water container to the mark with lukewarm water and add the Miele descaling tablets. Allow the tablets to dissolve completely—this is vital for best results. Regular descaling helps to prevent scale buildup in the machine, ensuring optimal performance over time.
Similar to maintaining a Breville grinder system, regular cleaning of the built-in grinder components will extend your machine's lifespan.
Follow the on-screen instructions during the descaling process. It's important to avoid interruptions, like opening the coffee machine door or removing brew units, as this can cancel the procedure.
After the descaling is complete, clean the water container and drip tray to remove any residues.
Post-Descaling Care Tips

After completing the descaling process, it's important to focus on post-descaling care to guarantee your Miele coffee machine remains in excellent condition.
Start by thoroughly cleaning the water container and drip tray to remove any residues from the descaling solution. Next, fill the water container with fresh, clean drinking water up to the indicated mark. If your machine displays additional instructions, be sure to follow them carefully.
Cleaning Precautions
Wipe up any spills of the descaling agent immediately to prevent damage to your countertops or floors. Always handle descaling agents with care, as they can be harmful to sensitive surfaces. Stick to Miele-recommended descaling tablets to avoid potential damage from other substances.
Regular Maintenance
Regularly descale your machine to prevent limescale buildup and clean essential parts daily, like the milk container and waste unit.
After dispensing about 200 portions, give the brew unit a thorough clean. Additionally, follow the maintenance schedule in your operating instructions to keep your coffee machine functioning at its best.
Check for any worn gaskets or seals as these are common sources of leaks that can develop after descaling procedures.
