Descale indicator remains on even after performing a descaling cycle.

Safety first: Unplug before filling with descaler.

• Repeat descaling: Perform the descaling cycle again, strictly following the Severin manual, including all rinse steps.
• Manual reset: Some models require a button combination to reset the descale indicator (e.g., holding two buttons for several seconds). Refer to the manual.
• Use correct volume: Ensure you use the recommended amount of water and descaler so the flow meter sees the full volume.
• If light will not reset: The flow meter or control logic may be faulty and need service.
