20 Most Recent Haier 45-Pint Dehumidifier - Page 4 Questions & Answers

Generally, it goes back in the reverse way it was taken out.It will only fit one way.

That's because when you reinsert the bucket into the bucket holder, it's not making firm contact with the bucket safety removal switch. When you reinstall it, be sure that the bucket fits "squarely" into the holder from top to bottom. Once it's inserted properly, it just not tilt down on the bottom.

No dehumidifier's constantly go from warm to cold depending on humidity levels

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.

The cap should just screw off the hose connector. You may have to carefully drill a 1/4" hose in the center of the threaded hose connector, once the cap is unscrewed. Some models require that, others don't.

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.

It takes a couple if tries. Have to press it twice to get down low and have to have at high or low speed.

If you want it to shut OFF before the tank is totally full, slide the float cup forward. if you want it to fill completely before shutting OFF, slide the float cup backward. Some folks prefer the half full, because the bucket is not as heavy to remove and empty, as it is when it's full.

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

On models a lttle later than yours E1, indicates that the air intake filter needs to be removed and cleaned. Probably, the same thing as yours. Before doing so, turn the Master ON/OFF Switch to OFF and unplug the unit. If you wash the filter use warm water and dish washing liquid, Rinse thoroughly and allow to completely before reinstalling. DO NOT operate the unit without the air filter in place.

Hope this helps you to troubleshoot and solve the problem.

The "LO" in the bottom reading, Indicates the current humidity extraction setting. If the unit was operating properly not that long ago (A couple of hours), the reason it is not doing anything, maybe that there is no humidity above "LO" = 30% at this time. Once it the humidity level rises above 30%, it should turn ON and function normally.

Also, was the timer set to turn the unit OFF at a specific time?

If the unit wasn't working properly a couple of hours ago.

Check the air intake filter for excessive dirt or clogs. Turn the unit OFF & unplug it before removing the filter. While the unit is OFF, remove the bucket, empty it if needed and carefully replace i, making sure it is fitted properly in to it's holder.

Air obstruction: The dehumidifier requires an minimum of 12" to 18" clear air space around the entire unit.

Hope this has helped you further troubleshoot and solve the problem. To assist you further, in case you have misplaced yours, I am including a link to your Owner's Manual that you can download and print for future reference. http://www.haieramerica.com/en/asset/product/4ba7175e54

Are you saying it has to be set below 40% to work? If that is the case, there may not be enough humidity, at this time, above 40% to activate the unit. Try setting it higher (a little over 40%) and just leave it alone for a while, to see if it will start up by itself, when the level rises above the setting.

If this is a basement application and the ambient air temperature is between 40 & 60 degrees F, dehumidifiers don't work well between those temperatures. Because the air temp at floor level is colder than at shoulder level. Raising the unit up onto a sturdy table, counter top, etc, that can handle the weight of the unit, plus a full bucket of water, will generally solve that problem.

Here is the data sheet for the HSU-07.
http://www.maocc.com/pdf/hdk/e1321aa.pdf
There appears to be 5 different versions of the HSU-07 Let me know which one matches yours and I will try and find a source.

HSU stands for humidity sensing unit.

Keep me posted... on the actual part match per the pdf file.

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.

What sometimes causes that, is that the water collection bucket is not sitting in the unit properly/tightly. When the unit turns ON, the vibration causes the bucket to move and lose contact with bucket safety removal switch. Try removing the bucket and reinstalling so that the top and bttom of the bucket fit squarely into the holder and the bottom doesn't tilt downward.

Also, check the humidity extraction level. It may be set to high. Lower it to 32-35%.

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

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

Dehumidifier is running but no water is in bucket

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.

For many window air conditioners this code is simply a reminder to clean the air filter. After like 750 hours of run time this code pops up and you have to clean the filter and then reset the unit before it will work again. To reset the code you need to simply unplug the unit and then plug it back in again.

Hope this helps; good luck.
