Problem Solution
The humidifier is not generating steam. Disconnect and reconnect the power adapter. Check if there was a power outage. Check that the water tank A3 is properly seated on the base unit A10. Clean the ultrasound disc A5 if it is dirty.
Air flows from the nozzle but no steam is generated. There may be too much water in the tank; pour out the excess. Clean the tank if cleaning agent residue remains. Clean the ultrasound disc A5. Use softer or distilled water if the current water is too hard.
Humidity in the room remains low. Clean the ultrasound disc A5. Ensure the water in the tank is not ice cold (use clean but not ice cold water). If the disc is damaged, contact a service centre.
The steam has an unpleasant odour. The water tank is dirty or being cleaned incorrectly. Clean the tank using clean cold water.
White dust forms on furniture nearby. These are limescale deposits from hard water. Use softer or distilled water in the SENCOR SHF 902BK.
Button A9 is lit red. There is a small amount of water in the tank. Fill up the water tank A3.
The tank A3 will not seat on the base unit. The tank can only be seated in one direction. Rotate the water tank A3 by 180 degrees and try again.
