Humidifier mode causes white dust to settle on furniture

Safety: This is generally not an electrical hazard but can affect air quality.

Steps:

• 1. Change water source: Use distilled or demineralized water in the humidifier tank.
• 2. Clean the unit: Wipe internal surfaces and the ultrasonic transducer to remove existing mineral deposits.
• 3. Install filters (if supported): If your Ariston model supports it, install a demineralization cartridge in the tank.
