TROUBLESHOOTING TIPS
The following is a troubling shooting guide to help you solve any issues that may have with the operation of the PM 908.
Trouble
Possible reasons
Solution
Power icon is off or does not
work.
Humidifier is not plugged into the power
outlet.
Connect power cord to electrical outlet and press
power button.
Power light is on but no mist
No water in water tank.
Fill water tank with water.
The mist has a strange odour.
A new machine.
Remove the water tank, unscrew the lid and let it air
out in a cool area for 12 hours.
It either has dirty water or the
water has been stagnant too
long.
Clean the water tank and refill with clean water.
Power light is on, but the machine
doesn’t work.
Too much water in the water basin.
Remove the water tank. Take a small cup and
remove some of the water from the machine’s water
basin. Reinsert the water tank and make sure that it
sits properly.
The volume of spray mist is too low.
Too much mineral scale in the
water basin.
Clean transducer.
Water is too dirty or water was kept too
long in the tank.
Clean the water tank and refill with clean water.
Abnormal noise
Vibration in the water tank because the
water level is too low.
Fill the water tank.
Machine is on an unstable surface.
Move the unit to a stable flat surface.
Spray mist is coming out of the area
around the jets.
There are gaps between the housing
around jet nozzles and the top of the
water tank.
Dip the nozzle in water for a while, clean it with a
damp cloth and put it back to the tank.
The following is not considered faulty operation:
1. If your water is very hard (containing abnormally high levels of minerals) the humidifier may produce white dust. This is not a
malfunction. The solution would be to clean the filter more often or use softer water.
2. If you stand very close to the humidifier, you will hear the gurgling sound of water. This is normal.
3. The machine operates very quietly but it is not completely silent. Noise levels less than 35 db is considered normal.
