Top 20 Haier 45-Pint Dehumidifier Questions & Answers

if power is applied then display should show current room humidity , if set is pressed then display should show current set point for desired room humidity , this has to be less than first display otherwise the control will think room has acheeved desired setpoint and shut off , the one of these i had seemd to have an overly sensative collection bucket full sensor and had to be "just right" for unit to run

I would set them to the relative humidity I wanted in that area. You want to keep below 50% otherwise you will eventuially get mold growth.

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

What is the exact model number?

Sounds like you're in a wintery environment. Most people operate a humidifier in those locations because the air is too dry. If that is your situation, I suggest you turn the dehumidifier off until Summer and save electricity. If will pull moisture out of the air in the summer.

Take the hose off and that should make it go to the bucket.

clean the dust off of the condenser in the front or the filter if it has one. no air flow results in overheating and no condensation across the evaporator coil.

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.

Here is a link to an Owner's Manual for a Haier 45 pint dehumidifier. Not sure if yours exactly like it or not, as you didn't mention a model number. You can download and print the manual for future reference.

John, there are 5 basic, yet solvable reason for what you described. Please pay particular attention to numbers 1 & 2.

1. The humidity extraction level is set to HIGH. Lower it to 32-35%.

2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.

3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.

4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to
clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.

5. Ambient air temperature at floor level is between 40 - 60 degrees.
dehumidifiers do not work well between those temperatures
(Unless, you have a Low Temp Unit). This applies mainly to
where the air temperature at floor level is colder than at shoulder level
in basement applications. Raising the unit up off the floor,
onto a sturdy table, counter top, etc, that can handle the weight
of the unit, plus a full tank of water, will usually resolve this
problem.

If none of the above solves the problem, it may be a case of the compressor needs to be recharged with refrigerant gas or that the humidity condenser sensor has failed. These things usually occur in units that are 5 years old or older. It's rare in a unit younger than that. But, it can happen.

Hope this helps you to troubleshoot & solve the problem. Thanks for choosing FixYa.

Unfortunately, for whatever reason, Haier does not list the Error Codes and what the problem is, in their Owner's Manuals. To find out what E2 indicates you will have to contact Haier Customer Support
1-877-337-3639. It's very important to have your Model Number handy before you call.

Hope this helps you to get the answer. Thanks for choosing FixYa.

Lisa, unfortunately, Haier for whatever reason does not list what error codes mean, in their Owners Manual. You will have to contact Haier Customer Support 1-877-337-3639 for that.

In the meantime, turn the ON/OFF Switch to OFF and unplug the unit for 15 minutes. Then, plug the unit back in and turn the ON/OFF Switch to ON. Hopefully, during that 15 minute timeout, the electronics reset and reverted back to the original factory settings. If they did, you can set the controls as you like.

Hope this helps you and thanks for choosing FixYa.

The first thing that comes to mind, is have you emptied the water collection bucket recently? If so, be sure that the bucket was properly reinstalled and is making contact with the bucket safety removal switch.

If you haven't emptied the bucket in the past few days, it may simply be full and will not start until it's emptied.

Hope this helped you and thanks for choosing FixYa.

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

If you just purchased and it won't turn ON, don't waste time trying to fix the unit. Return it to the place of purchase for a replacement unit or a refund.

doesn't pull water just runs fan with no moisture being drawn?

Hi, it simply means that the humidity level is lower then 35% the lowest setting on the dehumidifier...
It will not run when showing that...

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.

Since I answered your similar question earlier and now have more details on what happened. Shorting out the bucket full switch, more than likely caused more electronic problems in the control board.

However, there is one thing you can try. Turn the Master ON/Off Switch to OFF. Unplug the unit for 15 minutes. After the time has elapsed, plug the unit back in, turn the Master ON/OFF Switch to ON and hopefully, the electronics will have reset themselves during that time out. Before doing any of this, make sure the bucket' float valve is in the DOWN position.

If the above doesn't solve the problem and you decide you want to replace the control panel electronics go the link below, to find the closest Haier Parts Dealer to you.

The compressor relay's purpose is to start the compressor. A faulty relay can result in the compressor failing to cycle on. The relay is accessed from the lower rear of the dehumidifier. The relay is located in the terminal box which is located at the side of the compressor.


Before testing a compressor relay, unplug the dehumidifier to avoid an electrical shock hazard. Also, if the compressor uses a capacitor, it must be discharged first to avoid the risk of electrical shock.

The compressor relay can be accessed by removing the terminal cover box. The cover is held on by tension or with a retaining clip.
