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.

The drain tube or hole that drains into the bucket is probably clogged.

Turn the unit OFF and remove the bucket. Look in the cavity where the bucket was removed for a drain tube or drain hole. Using an 18" long plastic Zip Tie or something similar (No wire coat hangers) , that's appropriately sized to fit in the hole. Carefully feed the ZIP Tie into the hole or tube and thread it as far as you can. At some point the drain will curve, but you have to carefully get past this point. Once the Zip Tie has reached as far as it can, slowly pull it out while rotating it. This will loosen the clog. Once you have it half way out, be prepared for water to follow. This method should solve the problem.

  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.

The E3 Code, indicates that the air intake filter needs to be removed and cleaned. Be sure the unit is OFF and unplugged before removing the filter. Filter cleaning should be performed at least once every two weeks, as part of Routine Maintenance.

Dehumidifiers seem to be prone to cabinet rattles because of vibration from the compressor.

Have same issue with 3 year old Frigidaire dehumidifier purchased in 2012. Must unplug to stop compressor running with power switch turned off. Unit gets hot and smells. Unplugging creates arcs at outlet since unit is pulling a lot of power. Plugging back in after some hours will make it appear to run normally and again remove moisture but it will not shut off when the fan goes off (humidistat bad?) and the set-point is reached. Cannot leave plugged in due to safetty/fire/overheating concern. Have not found answer on this forum or any other so far.

I suspect the drain hole or tube is clogged and needs to be cleaned out. Turn the unit OFF and remove the bucket. Look for a drain hole or tube at the top, where you removed the bucket. Using an 18" long, plastic Zip Tie (or something similar, that's flexible. NO wire coat hangers) that will fit into the hole or tube. Carefully insert it as far as you can, You will come to a bend in the tube, but try to gingerly move it past the bend. Once you have gotten it as far as the Zip Tie will allow, slowly remove it, while rotating it. This will dislodge any clogs. Be prepared for water to follow, once the Zip Tie is removed.

Hope this helped you to solve the problem, Lynn..
