I have a Haier 45 pt dehimidifier that runs but doesn't dehumidify. I took the filter out and it was clean and I removed the front cover and the coils were very clean. I found a small (2 ice cubes worth) chunk of ice on the coil at the bottom. The ice chunk makes me think the freon is low. Can it be fixed?

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.

There are 5 basic, but 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 to troubleshoot & solve the problem. Please let e know.

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.

E2 Indicates that the filter needs to be removed and cleaned. It's a good idea to clean the filter at least once every 2 weeks, as standard routine maintenance. Be sure to turn the Master ON/OFF Switch to OFF and unplug the unit, before removing and cleaning the filter. You can access the filter by pulling on the filter frame handle on the right side of the unit, behind the front louvers. You can either vacuum the filter or wash it in warm soapy water (dish washing detergent), rinse it and dry it thoroughly, before reinstalling it. A hand held hair dryer will dry it pretty fast.

Hope this helped you to solve the problem.

Hi,

Here is a tip that explains what can be happening to make the dehumidifier showthat the bucket is full when it is not.

Yes, they do. The filter is located behind the louvers on the front. To remove it for cleaning, grasp the Filter Handle on the right side of the unit, on the same level as the louvers and pull it out. Clean the filter with a vacuum cleaner or luke warm water and a mild detergent. Thoroughly dry the filter before reinserting it.

If you have misplaced your Owner's Manual, I have included a link to it, that you can download and print for future reference. http://www.haieramerica.com/en/asset/product/4ba7175e54 Read over it and follow the suggested Routine Maintenance Guide.

Hope this helped you. Please let me know. Thanks.

Hi,
There are many reasons why a dehumidifier willnot work or collect water.

The lack of water in the bucket, may be a result of the humidity setting on the unit being to high. Try setting the level at 45% or lower. Also, be sure there's adequate air flow around the unit itself. It should remain a minimum of 12' from a wall or furniture. 24" is better.

If the above doesn't solve the problem, try this at home test. Place the unit in the bathroom, turn it ON and set the level as low as possible. Turn the shower ON hot enough to generate steam. Do not turn ON the bathroom's exhaust fan. As you exit the bathroom, close the door. Wait 15 to 20 minutes, before returning to the bathroom. When you do, turn the shower OFF and allow the unit to run for several more minutes. Then check the bucket for water. If there is any sign of water in it, it's working fine. It was probably a case of the humidity level being set to high the first time.

If there was no water in the bucket, the refrigerant gas in the cooling coils and the compressor may need recharging.

Hope this helped your to troubleshoot and solve the problem. Please let me know. Thanks.
