Dedicated descaling LED or icon flashes continuously and machine may limit brewing volume.

Safety first: Use only recommended descaling agents and follow the manual.

• Restart descaling: Fill the tank with descaling solution and start the descaling program from the beginning.
• Do not interrupt: Allow the full cycle to complete, including any pauses and rinses.
• Perform extra rinse: After descaling, run additional clean water cycles to ensure sensors and flow meter are clear.
• Reset indicator: Use the specified button combination to reset the descaling LED (varies by model).
• If light remains on: The control PCB may have a firmware issue; consult service if the machine otherwise works normally.
