SOLUTION
• Make sure that your dehumidifier is plugged in.
• Make sure that the water bucket is in the proper position.
• Check if the water bucket is full.
• Check if your dehumidifier has reached your set humidity level.
• Check the house fuse/circuit breaker box.
• Make sure that you have allowed your dehumidifier enough time to
remove moisture from the air.
• Make sure that there are no curtains, blinds, or furniture blocking the
front or back of the dehumidifier.
• Lower the humidity level.
• Make sure that all doors, windows, and other openings are closed.
• Make sure that the room's temperature is not below 41º F (5º C).
• Make sure that there is not a water vapor source in your room.
• Make sure that the air filter is not dirty. If it is, clean the air filter.
• Make sure that your dehumidifier is upright and is placed on a level
floor.
• Your dehumidifier may sound loud for the first two or three minutes of
operation while the compressor starts up.
• This is normal. Your dehumidifier has liquid refrigerant flowing inside of
it.
• Make sure that your dehumidifier is upright and is placed on a level
floor.
• This is normal. Your dehumidifier has an auto defrost feature that starts
when too much frost buildup occurs.
• If you are using the water bucket, make sure that the back drain plug is
in place.
• If you are using the drain hose, make sure that the hose is connected
securely to your dehumidifier.
• These are error and protection codes. See Understanding the LED
display codes.
