Question about LG LHD45EL Dehumidifier

2 Answers

I installed the LG model LHD45ELY8 in the basement over a year ago. I drain the water directly into a pump and through a hose to an outside drain. Found the unit not working. The bucket full light is blinking on and off. (as I mentioned, I am not using the dehumidifier's bucket) The display settings are PRESENT reads CH and SET reads 01. I shut power off and replugged power cord in, the humidifier starts and immediately shuts off again.

    Left unpluged for several hours, cleaned air filter which was very dirty and also cleaned drain line.
    Replugged power cord and again dehimidifier starts and immediately shuts off and same display readings and bucket full flashing red light. ANY OTHER SUGGESTIONS? Please advise.

    I cleaned the air filter which was very dirty and the drain tube as suggested without any change to the problem. I am open to any new thoughts that might correct the situation.
    Thanks in advance.

    The drain pump you mention, iI assume is the external pump that a hose from the dehumidifier dumps into. I have completely cleaned and filled it with water to make sure it is working properly. It is.
    As I mentioned before, I cleaned the solid plastic drain tube. From its external hose treads out the back of the dehumidifier is a one and a half foot piece of hose that goes into a hole in the drain pump. The pump when full pumps the water through a long piece of plastic tubing into the house drain.There is no solid connection between the drain hose and drain pump. The pump does not pull the water out of the dehumidifier, it is by gravity.
    The humidity control is on high.I checked the switch that the bucket activates when the bucket is installed, it seems to be ok.
    So far your suggestions are not solving the problem.

    Hi,
    I have no way of testing the coil if that is the problem.



  • shlake823 Sep 05, 2010

    I have no way of checking the bucket full sensor. How is it sensed when full?
    In answer to the air filter, it is perfectly clean and in perfect condition. It is not the problem.
    When the bucket is installed, a switch is activated. The switch seems to be working fine.

  • shlake823 Sep 06, 2010

    I do not plan to buy a multi-tester to check the coil.
    I spoke to two local dealers and both told me that LG dehumidifiers are a piece of junk and that I should be happy that I got 2 years out of the unit. Both advised me to buy a Frigidare unit. Any comment?
    Also, I went to Home Depot where I bought the dehumidifier and noticed that they no longer carry
    the LG brand dehumidifiers.

The drain pump is clogged or not holding pressure.If you are using direct drain instead of bucket,then check the drain pump ,if its cleaned and not clogged then the connection of drain pump to drain hose check that.It must not be pulling the water out to get drained.The pump is worn out.Turn the humidity control to maximum,if in case its got set on low or OFF,then check.Also check the switch which is actuated when bucket is inserted.Its on the machine,not in the bucket.Where the bucket is placed. Thanks. Keep updated for any more query. You can rate this solution and show your appreciation

    The air filter which you cleaned which was dirty.Is that air filter very old or newly installed.if its very old,try replacing the air-filter and check.There is a sensor which tell the machine that the bucket is full.In your case you have not used bucked but direct drain pump to drain the water.But if this bucket full light is coming up then its definitely the bucket sensing sensor in the machine that is got activated.or the sensor is got faulty,so its throwing wrong signal to the control board that bucket is full,when there is no bucket.this sensor has to be checked.Also if you have bucket at present with you for you dehumidifier then,insert that bucket and see if in-case the light is going out ,once the sensor detected that bucket is placed and the bucket is empty,you can then again use your direct drain system to get the water drained.


    thanks for keeping updated with your query.

How long did you leave it unplugged? It should be left unplugged for several hours. Also check that the drain tube isn't plugged up and that the filter is clean.

    I would test your coil. That is what makes the water condensate and turns it into water

    If possible, you can purchase a very reasonably price multi-tester so you can test it. That may be your problem. Most common problem anyways.

    I completely agree! Usually when I tell people to throw it out and get a new one, most people get a little angry that I didn't help fix the one they have. But I do agree, scrap the LG junk and go with Fridgidaire

Basement smells musty, fan won't stay on continuous


Barbara, are you running the unit in a continuous mode (i.e Using a hose to drain the unit)? Or is the water draining into the water collection bucket?

If you are not using a hose for continual drainage, the fan will not run constantly. It requires that, for continual operation.

Also, you may have the humidity extraction level set to high. Lower it to 35%. Also, remove and check the air intake filter, as it may need cleaning.

Dehumidifiers that are not Low Temp models have a difficult time operating in basement applications. Because the air temp at floor level is colder than at shoulder level. At temperatures between 40 & 60 degree F, regular dehumidifiers struggle to keep up. Raising it up off the flow on to a sturdy table, counter top, etc that can handle the weight of the unit, plus a full bucket of water can really help.

I hope this was of assistance and thanks for choosing FixYa.

Bought a Delonghi dd50pc dehumifier last week for my basement and I have the hose going uphill and out a window but the pump always shuts off after 3-4 minutes, filling the tank instead. Now when I lay...


You really answered your own question. The pump in the dehumidifier only has so much water lift capacity. By trying to run it up and out, you have exceeded the maximum lift capacity. Using a floor drain or even a bathtub drain in the basement will probably work, as long as the hose is not to long.*
However, if you can use a floor drain, there's no need to use the pump function. You can use the continuous drain on the back of the unit. using the drain hose provided for that application.

*The 13 ft lift capacity noted in the Owner's Manual includes whatever length of hose you're using to get to the window. As there is some friction loss involved. But, they fail to point that out.

Hope this helps you and thanks for choosing FixYa.

Where do i find the model number for an older model goldstar dehumidifier and where can i buy a hose to connect it directly to the sump pump?


Any garden hose will fit the drain connection on your dehumidifier. However, the hose can not be longer than 5 feet. As the drainage relies entirely on gravity to drain. Connecting it directly to a sump pump is not a good solution. Allowing the hose to drain into the sump pump's water collection tank is your only option.

Hope this helped you.

Hi, I have an LG dehumidifier, model number LHD650EBL. I have a hose attached and inserted directly into a drain in my basement, bypassing the water tray. Problem is, my dehumidifier is saying...


Try to see if operating the float lever by hand can make it turn off the 'bucket full' message. Maybe use a rubber band or tape to keep it in the on position vs. the 'bucket full' off position.

Check to see if the bucket has to be inserted for the unit to operate, and if the bucket has a nozzle to hook a hose up to at the bottom. I have a dehumidifier of a different brand that has this feature that works with the bucket in, but with the drain nozzle on the bucket connected to a plastic tube that leads to a drain for continuous operation without having to empty the bucket.

How is your hose attached to the unit if it isn't attached to the bucket?

Good luck on this repair.

Bucket fills up instead of water flowing out hose


There must be a blockage in the hose causing the water to back up and flow into the bucket. Try pushing a flexble peice of wire through the hose to unblock it.

When you install the drain tube, be sure that it is placed into the drain hole in the dehumidifier. You then will be able to "latch" the tube at the hose end by lowering onto the outer hole opening. This maintains a tight connection and the water will drain properly.

Hose connector


First, is the dehumidifier high enough so that the hose isn't 'backing up'? Otherwise, attach a small radiator hose clamp to hold it on.

Vertical draining


Water only runs down hill. To accomplish your task you would need a small condensate pump to get the vertical lift to transfer to your sump. as an example "http://www.hartell.com/corp/details/0,,CLI1_DIV32_ETI3740,00.html"

The condensing unit does not run consistently, it clicks on every minute or so.


It sounds like there is an issue with either the controller board or humidity sensor. LG has a 5 year warranty on these models. You may want to contact them first instead of opening it up because it could void the warranty. My recommendation is to have this serviced if it is under warranty. They usually will tell you of a service center nearby which will service it free of charge since it is under warranty. If you do not live near a service center they may ship you a replacement and you send your old dehumidifier back to them. Make sure you have your reciept when you contact them so they can verify it is under 5 years old.
