The Efficiency Factor (EF) is a guide to a dehumidifier's operating cost. The EF is the amount of water, in litres, a dehumidifier removes at 27°C (80.6°F) and 60 per cent relative humidity for each kilowatt hour (kWh) of electricity. If electricity costs 8 cents a kilowatt hour, which it does in many parts of Canada, a unit with an EF of 1.2 will remove 15 L (32 U.S. pints or 3.3 imperial gal.) foreach dollar in electricity costs. An advanced unit with an EF of 2.4 will remove 30 L (63 U.S. pints, 6 1/2 imperial gal.) of water for each electrical dollar spent. Because condensation gives off heat a dehumidifier acts as a heat source. This can be useful in spring or fall, when basements tend to be cool. In mid-summer, the heat added by a dehumidifier is counterproductive.

How do you clean the filter

In order to look up the filter change procedure I would need the specific model number. However, filter changes or washing should be done regularly. Look for a very simple lift-out design that is washable in the kitchen or laundry sink. Soak in soapy water and rinse with spray nozzle.

As for the symptom "Blows out warm air" this is expected. The dehumidifier is less than 100% efficient, meaning that the energy that is used produces heat in the exhaust air. A 100% efficient design would still send all the heat energy of condensation (endothermic phase change) into the exhaust air. You should expect 1072 BTU per pint (1 pound of water). This is far more than the heat of crystallization (144 BTU per pound of ice) and therefore much more sensible when you feel the discharge air from the dehumidifier. Dehumidifiers typically operate in basements to both warm and dry the area where a sump pump may be operating to remove the water that seeps through the foundation. A dehumidifier is not a good idea for warm areas of the house. This will decrease the efficiency by increasing the temperature differential needed to get the evaporator coil below the dew point to cause condensation. The condenser coil will be much hotter than expected if the unit is operated in a warm humid room. Only air conditioners which discharge condensate and exhaust air to the outside of the structure should be used to cool a room.

I am showing a HI on my current humidity/set humidity display what does it mean

The HI indicates that the current humidity is 90%+ in the room/unit. You should check if the filter is clogged. I've seen this message in dryer locations when the dehumidifier coils ice up. Check the coils (behind the filter) for any build up.

If this is a brand new dehumidifier, leave it on for an hour to see if it auto-defrosts. (A similar wait is needed if the room is cooler that 60 degrees F.)

If the unit continues to freeze up and the room is over 60 degrees, you may have a refrigerant leak in the dehumidifier. If it is still under warranty (5 years on the cooling system), contact Haier. The warranty service number is 1-877-337-3639.

The manual for the DE65EK is available here: . You will need Adobe Reader or a similar program to access the manual.

I hope this helps.

I have an lg dehumidifier model # LHD65EBLY8. The bucket is full light keeps coming on even though it is empty. Because of this, it will not stay on and my basement keeps flooding. Do you have any...

booklover, if the the bucket is not properly installed, the unit will not turn ON. If you remove the bucket and look at the left top corner it, you will see a float device arm. It that's stuck in the UP position, jiggle the handle, so it will return to the DOWN position. In addition, that handle must make contact with the bucket removal safety switch, if not the bucket is improperly installed and the unit will not start.

Since you are using this unit in a basement, I highly recommend that you raise the unit up off the floor onto a sturdy table, counter top, etc. that can handle the weight if the unit, plus a full bucket of water. As the air temperature at floor level is colder than at chest level. The coils on your model will start to freeze at 60 degrees F and affect it efficiency, Because it is not a Low Temperature model designed for basement applications.

In addition to the dehumidifier, you would be wise to install a sump pump, if your basement floods as bad as you made it sound. Combining a sump pump with a dehumidifier will guarantee a dry basement, all the time.

Hope this helped you to troubleshoot and solve the problem.

How do I clean the dehumidifier?

A dehumidifier works just the way an air conditioner works but in a reverse manner. If you encounter a problem with your dehumidifier then it would be repaired the same way you would repair an air conditioner. As such a dehumidifier does not require much cleaning apart from changing the filter. When the filter and coils of the dehumidifier are choked with dirt, it may not pull out moisture from the air properly. The efficiency of the dehumidifier gets decreased and the only solution is, to clean it thoroughly. In order to assist you with the cleaning procedure of a dehumidifier, following are a few tips:
  1. Remove the water tank/container and clean it after draining the water. Depending on the usage the container must be cleaned regularly.

  2. Cleaning or changing the filter is also important for the main function of ensuring a healthy atmosphere is performed by the filter. Mix some bleach with warm soapy and clean the filter. It will help to get rid of the bacteria, molds and mildew.

  3. Use a vacuum cleaner to clean the evaporative coil/hot coil. Scrub off the dirt using a brush but make sure that you don’t bend the fins while cleaning.

  4. Clean the condenser or the cold coil the same way. If the humidifier is working in a room where the temperature is below 60 degrees Fahrenheit then check the coils whether it is not icing up.

  5. See to it whether the fins are bent or not, if they are bent then straighten them out using a fin comb otherwise it might obstruct the effective working of the dehumidifier.

  6. And yes do not forget to clean the fan blades and other parts of the dehumidifier.

  7. Keeping in mind the humidity level of your room, sets the humidistat of the dehumidifier as keeping it too low or too high may only make the dehumidifier to run longer than necessary.

Also before you start with the work of cleaning the dehumidifier, make sure that it has been unplugged.

When running load noise coming from black cylinder

That part you identified is the compressor of the dehumidifier. Compressor is probably bad or going bad. When compressor go bad the valves start making noise and they lose alot of there efficiency.

Dehumidifier efficiency

I'm surprised that you are trying to dehumidify if you are in the northern hemisphere right now.

But, before you go off trying to fix the refrigerant, see if you can get a glass of ice water to sweat near the dehumidifier. While relative humidity might be high in cold climates right now, it's a relative number, as the total grains of moisture is far lower than what it would be in a warmer climate. Cold air saturates easier, because it holds less, moisture.

Most people use a humidifier in the winter because they want to saturate the air with water, which is better for the human body, and minimizes static electricity.

I can help you diagnose the dehumidifier if you want. The coil should only get to 40 degrees or so. But the sweating glass of water will tell you if there is enough moisture in the air for the dehumidifier to wring out.

Works well but

Yup, they eat energy.

An electric dehumidifier includes a refrigeration cycle that is very similar to a window AC units and refrigerators. They cool the air in the basement to condense and collect water and remove humidity, heat the air as a required consequence of the refrigeration cycle and dump it back to your basement.

Two sources of humidity in basements include warm outside air that naturally cools due to below grade earth contact and water passing from the ground though the floors and walls and evaporating into the basement. Dehumidifiers do most of the work in the summer when higher temperatures outside enable air to hold more water content.

In the winter, cooler outside air contains less moisture by weight eventhough it may be raining and the relative humidity in basement will be less because the air is warmed relative to the outside. The lower moisture content in the winter also absorbs the water passing through the walls and floor.

From an energy perspective, you may want the humidity set NOT below 50%. This will keep humidity below the level mold desires, but prevents the dehumidifier from doing more work and eating more energy than needed. A cheap battery powered temp/humidy meter left in your basement will help. Sources that include the "mold triangle" (temperature, water & food) often separate fact from expensive hype.

If the dehumidifier doesn't keep up, consider adding a moisture barrier to the basement walls and floors such as Dry-lock and floor paints to ****** moisture entry. Moisture barriers act very similar with water as insulation does with heat. They don't eliminate the need for a dehumidifier, but they reduce the work they do and energy they eat.
