Frequently Asked Questions

Why does the descale light stay on after descaling?

The machine’s sensor or control system may not have registered the descaling process correctly, requiring a manual reset.

Can I reset the descale light without completing a full cycle?

It’s best to complete the descaling cycle first, then manually reset the indicator to avoid future confusion.

How often should I descale my De’Longhi espresso machine?

Typically every 2-3 months, depending on usage and water hardness. Use a descaler like EcoDecalk or EcoDecalk for best results.

Is it safe to use vinegar instead of descaling solutions?
