Indicator lamps
Phenomenon Check points
The water supply lamp turns on and
off repeatedly
• Even after the water supply lamp has turned on, depending on the FAN
setting, water in the humidifying tray may ripple and move the oat causing
the water supply lamp to turn on and off repeatedly.
(This is because the on/off status of the water supply lamp is dependent on
oat position.)
¼
Stop operation of the unit and unplug the power supply, then ll the
water tank with water.
