Display shows CLEAN continuously even after running a cleaning cycle.

Safety first: Unplug the unit before extended cleaning.

Run a full, uninterrupted clean cycle:

• Fill the reservoir with descaling solution per instructions.
• Start the CLEAN cycle and allow it to run to completion without stopping or unplugging.

Repeat if necessary:

• If the CLEAN light remains, run a second full descale cycle.
• Afterward, run 2–3 full reservoirs of plain water to flush the system.

If the CLEAN indicator still will not clear, the flow sensor or control board may not be registering the cleaning cycle correctly and may require service.
