Question: what is error code e2?
Document: That had became a cycle that every 10 days or so, I would have to shut it down to let the ice melt and restart it. I called Haier customer service. Instead of returning it for service, they shipped me a replacement unit after I signed a form promising to get rid of the non-working dehumidifier appropriately. The replacement unit only worked for about 2 weeks with a E2 error code on the display control panel. I called the customer service again to complain.
haier brand dehumifiers are junk. Bought one brand new and had same problem as everyone else within 6 months of purchase. E2 error. Called haier and they would not even tell me what the problem may be without receipt of purchase. No receipt, and they will not even take your phone call? Terrible. Tons of people on-line wrote about their experience with the same error.
Unit purchased in July of 2012, used very little, next spring showed the E2 error, after contacting the company and was told it was a compressor failure and to mail in the labels and receipt for replacement. After being told unit shipped in June we are told every week that they will call back with a tracking number and forwarding the issue to the highest level of customer support. Never a call back.
it is great my wife breath and son to it air good and dry for great breath for people with breath problem
What's not to like on this great dehumidifier? It does what it is supposed to and is trouble free. The bucket is easy to empty.
We purchased this dehumidifier and placed it in our basement with a setting of 45% humidity. It detected around 55% and started running. After 3 days the bucket was empty so I called support and they told me it takes 4 to 5 days for the bucket to fill the first time. After 17 days the bucket was still empty so I called support again. They tried to tell me it was empty because I set the target humidity level too low and that it is normally at 50%.
We placed this dehumidifier in a basement room and it worked like a charm. It requires emptying about once a day and the room has no musty odor and the humidity feels just right. It has a &#34;smart sense&#34; feature that we use to maintain a steady amount of humidity.
We bought the to dry out a very damp apartment. It pulled out 10 gallons a day for weeks! This unit is clearly designed for a large space, and had no problem handling our 800 Sq. Ft. apartment. The downsides: It is a bit noisy, and it would be nice to have a shut off switch for the full tank alert. And of course, it uses a fair amount of electricity.
This unit is great at removing moisture from the air, but I would only purchase this unit if you have a life that you can dedicate to emptying the bucket. For the first few days we emptied the bucket about every 8 hours, whether it needed it or not. We noticed that the water level was very close to the top of the bucket but thought that we has gotten to it just before the auto cut off switch activated. WRONG!!
This is the second Haier dehumidifier I ordered from Amazon as the first one I received leaked from the housing immediately after the initial receipt.. I'm glad I order the unit from Amazon as they replaced it with no hassle. I originally contacted Haier with the first one I received and they said they would send a service person to repair it; however, the service person never showed up within the period stated by Haier representatives. The second unit appears to be working satisfactorily after one month of operation.
Answer: Turn off the unit, unplug, wait 15 minutes, plug back in and turn on. That resets everything. That may work. If it doesn't, call Haier customer service. If your unit is less than a year old they will send you a new one.
