Unit in defrost too long. Check defrost sensor cable for proper connection. If error persists, sensor assembly may require replacement. Contact service.

E9 is related to the humidity sensor. What's happening is the sensor cannot sense humidity, so the unit turns off. This is common with newer units due to the location of the sensor being by the filter. The sensor most likely has gotten dirty and the unit got cold enough that ice formed. The ice then damages the sensor. This will happen over time without you noticing.

If it's under warranty, then you should be able to get it repaired for free.

Otherwise you'd have to replace the sensor yourself. If it's under warranty, don't open the unit up as that will void your warranty.

  1. Check that the filter in the unit is clean.
  2. Check that the room temperature is above 41 degrees.
  3. Check that the humidity isn't set too low, recommended humidity is 45~50%
  4. Make sure that the unit has plenty of space all around to allow for sufficient air circulation.

Your humidistat is stuck in the "on" position. Probably need to replace it.

A dehumidifier works in a similar way to an air conditioner, cooling the air that passes through it so water vapour will condense and collect into a container.

If the fans are working and air is circulating through the unit but no water is being collected the internal refrigeration system probably has a fault...

Could be the humidity is low enough it isn't turning on. Try to lower the humidity setting to see if it will turn on. Once the humidity gets down to about 50-55%, dehumidifiers don't work very well at pulling out the humidity..
