There are 5 basic, but solvable reasons 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%. If yours is a mechanical
unit. Turn the Humidity Extraction knob to Maxi,u.

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 - 65 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.

I hope this helps you to trouble shoot & solve the problem. Thanks for choosing FixYa.

The problem, may very well be, that the humidity extraction level is set too high. Lower it to 35% and see what happens. Keep in mind, the lower the percentage of the moisture/humidity setting, the more it extracts from the household air. The higher the setting, the less it extracts from the household air.

Also, remove and check the air intake filter to see if that needs to be cleaned. It should be cleaned at least twice a week during the operating season.

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

It could be what you say or it could be that the humidification extraction level is set too High. Try lowering the extraction percentage to 32 - 35%.

If that doesn't help and you'd like to order replacement control board/panel. Call Haier Parts and Technical Support 877-337-3639. But, you may find it cheaper to replace the unit, then repair it.

Remove the bucket and remove the plastic cap on the bottom of the bucket. Then take the rubber insert out of the cap and save it. You will use it later. Using the hose that came with the unit, thread it through the cap opening and add the washer to the cap. Screw the cap to the mating connector on the bucket. Be sure to use the washer or the connection will leak. Now, thread the hose through the round hole and extend the hose to the back of the unit. And finally, replace the bucket in it's original position in the unit.

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

Hi,

If you are getting no water condensing at all I would have to disagree with the phone support information you got. If the coils or filter were having trouble we would have frosting problems which would give you some condensation and water removal.

On these units if the compressor is running and no water is being pulled from the air it indicates there was a leak in the system and the unit has lost it's refrigeration (freon) charge.

Unfortunately Haier technical support and documentation is lacking for portable appliances such as this.
