Setup
Before beginning the descaling process, ensure your appliance is unplugged (if applicable) and cool. Remove any coffee grounds, filters, or capsules from the machine. Empty the water reservoir.
For kettles, ensure it is empty and cool.
Operating Instructions
General Descaling Procedure:
- Empty the water reservoir of your machine.
- Dissolve one packet of Urnex Dezcal powder in 32 oz (1 liter) of warm water. Stir until fully dissolved.
- Pour the solution into the water reservoir of your machine.
- Initiate a brew cycle. If your machine has a descaling cycle, follow its specific instructions. Otherwise, run a full brew cycle.
- After the cycle, discard the descaling solution from the carafe or drip tray.
- Rinse the water reservoir thoroughly with fresh water.
- Fill the reservoir with fresh water and run at least two full rinse cycles to remove any residual descaler.
- Your machine is now descaled and ready for use.
Specific Appliance Instructions:
For Coffee Brewers (Drip, Single Serve):
Follow the general procedure. For single-serve machines, ensure no pod is inserted during the descaling and rinsing cycles.

For Kettles:
Follow the general procedure. After pouring the solution, allow it to sit for 15-30 minutes before boiling. Then, boil the solution, discard, and rinse thoroughly with fresh water multiple times.
Maintenance
For best results, descale your equipment quarterly. However, the frequency may need to be increased depending on the hardness of the water in your area. Signs that your machine needs descaling include:
- Slower brew times than usual.
- Coffee brewing cooler than usual.
- Visible mineral deposits (limescale) in the water reservoir or on heating elements.
Regular descaling prevents damage to heating elements, corrosion, and component malfunctions, extending the overall lifespan of your appliance.
Troubleshooting
Problem: Descaling solution not flowing through the machine.
Solution: Ensure the water reservoir is properly seated and the machine is powered on. If the machine is severely clogged, you may need to repeat the descaling process or consult your appliance's specific manual for deep cleaning instructions.
Problem: Residue or unusual taste after descaling.
Solution: This indicates residual descaler. Run additional rinse cycles with fresh water until no taste or residue is detected. It is crucial to rinse thoroughly.
Problem: Machine still brewing slowly or coffee is not hot enough.
Solution: The machine may require another descaling cycle, especially if water hardness is high or if it hasn't been descaled in a long time. If the problem persists after multiple descaling attempts, the issue might be mechanical and require professional servicing.
