Unit will not run. E2 on display. controls do not work.

Reset the system read your owner manual section troubleshooting or download from www.retrevo.com or www. manualslib.com

God bless you

E2 Code indicates a Sensor Error automatic shutdown. To find out which sensor it is you will have to call Haier Customer Support 1-877-337-363.

In the meantime, turn the unit OFF & unplug it for 15 minutes. Then plug the unit back in and turn ON. ON. Hopefully the unit reset itself and reverted back to the original factory settings. And you can set te humidity extraction level where you desire. If the error code reappears, definitely contact Haier, as youtr unit is still under warranty.

need make ,model # , s# get asap might be able to help

E2 error indicates that the air intake filter needs to be removed and cleaned. Turn the Master ON/OFF Switch to OFF and unplug the unit, before removing the filter. If you wash the filter, it must be completely dry, before reinstalling it. DO NOT run the dehumidifier without the clean filter installed.

Hope this helped you to solve the problem. Please let me know. Thanks.

After turning the Master ON/OFF Switch to OFF, unplug the unit for the wall outlet and wait 12 -15 minutes. Then plug the unit back in to the wall outlet and turn the Master ON/OFF Switch to ON. That 12 - 15 minute timeout, should have allowed the unit to reset it self and clear that unknown code.

Since it has been working well for 4 days, it may be a case that the unit needs to reset itself. To accomplish this, turn the Master ON/OFF Switch to OFF. Unplug the unit from the wall outlet and wait 12 - 15 minutes. Then plug the unit back into the wall outlet and turn the Master ON/OFF Switch to ON. Set the controls as you normally do. Hopefully, that timeout allowed the unit to reset itself. Also, check to make sure that the water collection bucket is installed properly and is making good contact with the safety switch.

Hope this helps you solve the problem.

Jason, currently the only 45 pint dehumidifier that Haier sell is Model # DE45EK or DE45EK-L or EK-T. If any of those matches the Model Number of yours, you can down load and print the Owners Manual from the link below. However, the model numbers I listed make no reference to Error Code E2. If your Model Number does not correspond to any of those numbers, your unit is probably no longer manufactured or available.

With that said, there are two things you can do. First, turn the Master ON/OFF Switch to OFF. Unplug the unit from the wall outlet and wait 12 - 15 minutes. Then, plug the unit back in and turn the Master On/Off Switch to ON. Did the Error Code clear itself. If so, set the controls as you normally would.

If that didn't solve the problem you can contact Haier Customer Service at 877-337-3639 and they will advise you what to do, to clear the error code.

Hope this helped you to solve the problem.

Dehumidifier (DE45EJ-L) shows only E2 on the display -- no "buttons" work. Had been working perfectly -- we turned it off a few days ago. Any suggestions??

DIY fix for Duracraft TEC10E E2 error, in case it's useful for others:
(When I tried to get a replacement temperature sensor via UK/Ireland support (kaz.com -> www.hot-europe.com) I was told that a replacement sensor was not available, nor was my unit serviceable).
Anyway, after a bit of messing with a variable resistor, I found that it would trigger E2 at a resistance of 560-580K, and also at resistance < ~1K (I stupidly destroyed the faulty temperature sensor trying to take it apart, without first checking what kind of resistance it presented, so I don't know whether mine broke OC or shorted).
Assuming an NTC thermistor, and a threshold of 0degC - the sensor is just to stop the dehumidifier cooling coil from icing up AFAIK - a 150K NTC thermistor with 'B'(25/100) value of 4400 should give a suitable replacement, with a 0degC resistance of 579K.
I wasn't able to find an exact such replacement, but I got a 150K/B~4000 from Maplin, put a 170K resistor in series, sheathed it up and installed it, and initial results look good - putting an ice-cube on the new sensor will trigger an E2 on the unit.
YMMV.

What does an E2 code mean?

I have a Haier Dehumidifier that is about a year old, I emtied the bucket and put the bucket back into place and hit the start button and nothing happen I unplugged the unit and error code E2 keeps comming on
