20 Most Recent Haier HD456 Dehumidifier - Page 5 Questions & Answers

Error E2 means Temperature Sensor error. its possible that the sensor need to be replaced.

First try to unplug the unit for 10 mins and plug it back in. If error repeats, call for service customer support 1-877-337-363.

Hope helps.

Hazel, I assume you want to know how to find and remove the filter for cleaning.

The filter is located behind the front air intake louvers and depending on which model you have, the filter can be accessed one of two ways. Before you attempt to remove the filter turn the unit OFF and unplug it.

1. Remove the bucket from it's holder. Look up inside the bucket cavity, just inside the unit behind the louvers and you will see a tab type pull handle. This is the handle to the frame of the filter. Pull it down and out.

2. As you're facing the unit on the fight side just behind the louvers, there will appear to be a trap type door. Open this door and you will have access to pull the filter out.

You can clean the filter in one of two ways: Vacuum it or it it's really dirty, wash it in warm soapy (dish washing liquid), rinse and dry thoroughly. NEVER operate the dehumidifier without the filter in place. Doing so, can cause damage to the unit.

Hope this helped you. Please let me know.

If the evaporator coils behind the filters become too dirty condensation can be seriously ********. Check to see if the fins require any attention; they can be cleaned very carefully with a toothbrush and some water usually. If the buildup has become severe special chemicals need to be used on the unit- not something recommended the average person attempt. If the fins are clear check other airflow issues. Dehumidifiers generally need a period of 3 days to balance an area properly when functioning and sized appropriately.

The arrow down button lowers the humidity level to what you want to extract and maintain. The higher settings remove little to know humidity and maintains a higher humidity level.

If you're trying to extract a lot of humidity/condensation, lower it to 35%.

Just a regular garden hose, no longer than 5 feet, is all that's necessary. Even a clothes washer, water supply hose will work. As the female connector fittings are the same size on both.

There are 5 basic, yet solvable reasons for what you described. Please pay particular attention to numbers 1 & 2.. Number 2, you have already addressed.

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 humid-i-stat 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.

Hawkster, there are 5 basic, yet 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 you have an analog unit
(no LED screen) turn the humidity extraction knob to Maximum.

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

Hi,
There are many reasons why a dehumidifier willnot work or collect water.
Here is a tip that I wrote to help people to figure out what is going wrongwith their dehumidifier

There are 5 basic, but solvable reason for what you described. Please pay particular attention to numbers 1 & 2. However, running to dehumidifiers in the same proximity may be the problem. ON is doing the lion's share of humidity extraction, leaving little or nothing for the other to extract.

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

Most counties and cities have a plan for the disposal of old dehumidifiers, AC units, refrigerators, etc.
This is because of the Freon gas that may still be in the compressor. Contact your local officials about their disposal site.

If the machine's compressor runs when you switch it on, then turn the machine on maximum and let it run for an hour or so. Then check the coils in the back with your hand. If they are not getting cold at all, then there is a significant problem with the refrigeration process in the unit. It may have developed a leak and allowed your refrigerant gas to escape, or there may be another internal problem with the compressor. Either way you would need to have it serviced by a fridge technician, or more likely just replaced with a whole new unit since both options can potentially cost about the same.

If the unit runs normally and the coils are getting cold, then make sure they are not totally icing up which will impede the unit's performance. If your dehumidifier is freezing up then that probably means the unit itself is actually working well, and you probably just have the unit turned up too high for the conditions.

Try turning down the setting on the unit so that it cycles on and off every few hours and does not run continuously.

Also try using some warm soapy water to clean off any dust or oily residue from the cooling coils in the rear of the unit. Remember to also clean the air intake filter while you are at it.

The ambient temperature in the room may also be a bit too low, so you can try adding some heat to the room if necessary. A dehumidifier will not work properly if the ambient air temperature is too low. Basically, the warmer and more humid the room is, the better they work. Since warm air rises, you can even try lifting the unit higher up off the cold floor onto a bench or table where the air is warmer.

Sometimes the drain tube leading to the bucket is clogged. You can often clean this out by inserting the pointy end of a long heavy duty plastic zip tie and jiggling it around a bit. Do not insert anything metal or sharp into the tube or you may damage it.

Without knowing which model number you have, I can't point you in the right direction. However, there ares some other causes, that you should address.

1. The humidity extraction level is set to high. Lower it to 35%.

2. Air flow obstruction. Maintain at least 12' of clear air space around the entire unit.

3. 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,

I hope this helped you to further troubleshoot & solve the problem.

The unit freezing up doesn't surprise me at all. If the temp in your room is 60 degrees then the temperature of the air will be around 40 degrees and the coil is about 20 degrees. Your expecting to much, the tempature is to cold to work properly.

If the unit runs normally and the coils are getting cold, then make sure they are not totally icing up which will impede the unit's performance. If your dehumidifier is freezing up then that probably means the unit itself is actually working well, and you probably just have the unit turned up too high for the conditions.

Try turning down the setting on the unit so that it cycles on and off every few hours and does not run continuously.
