Humidifier or dehumidifier controls are unresponsive or change settings by themselves.

Safety: Unplug the appliance.

• Dry the panel: If the panel has been exposed to water, allow it to dry for 24 hours in a warm, dry environment.
• Clean surface: Wipe the touch area with a dry, lint-free cloth to remove residue.
• Power reset: Plug back in and test. If the issue persists, the touch panel or cable may be damaged.

Replacing the touch panel assembly or cable is often required for persistent faults and should be done with the correct Philips parts.
