Frequently Asked Questions

The most common reason is that the machine’s internal sensor hasn’t registered the descaling process as complete. Resetting the machine manually usually fixes this.
Can I ignore the descale light?

How often should I descale my De’Longhi machine?
Typically, every 2-3 months, but it depends on your water hardness and usage frequency. Using a water filter can reduce descaling frequency.
