Why is your Midea dehumidifier not collecting water even though it is running?
As we saw in the post on why would a dehumidifier not collect water, this problem is not a preserve of the Midea brand name dehumidifiers only.
Any unit can develop issues, as we have seen in the past. For instance, we have seen why dehumidifiers blow cold air instead of warm air.
A dehumidifier is a device or appliance that draws moisture from the air, lowering the humidity in effect. If it fails to do this, it will not help with the humidity levels.
So, why is your Midea dehumidifier failing to collect water? The dehumidifier compressor fails, the humidity level is set wrongly or the power cord/socket is broken. Also, the dehumidifier could be dead.
There are tens of reasons a Hisense, Midea, Honeywell or even Frigidaire dehumidifier would not collect water. Keep reading to see the main ones:
Dehumidifier not collecting water: simple checks
Away from the tech things that make a dehumidifier fail to collect water, always start with the simple things.
1. Low temperature – no excess humidity
Indoor humidity and temperature go hand-in-hand somehow. Therefore, if the humidity level is, say, about 55% and the temperature is 75 degrees Fahrenheit, the dehumidifier will draw moisture and collect water.
However, if the temperature is 50 degrees Fahrenheit, the dehumidifier will not work. There simply is not enough moisture for the dehumidifier to collect water.
2. Dehumidifier is not the right size for the space
Dehumidifiers and humidifiers have space rating. And so do the air purifiers!
Therefore, if a dehumidifier has a manufacturer rating of 300 square feet and you try to use it for 600 square feet, it is not going to work.
It is better to get a large dehumidifier and not need to use all of its dehumidifying power. For example, a Frigidaire 70-Pint dehumidifier rated for 1500 square feet can do a faster job in 700 square feet but it will seem to collect little water.
Using a small dehumidifier in a large room will tend to collect quite a lot of water, but it might really not bring the humidity down.
Just find the right dehumidifier for your space size. That way, you remove all guesswork from the picture.
3. Power, humidistat, filters not working
Make sure that the dehumidifier is plugged into power and that the power cord is working. For all corded home appliances, if it fails, the first thing is to plug it in another power outlet.
Another thing that you need to be sure of is that the humidistat is working correctly. If it is incorrect, it might automatically stop the dehumidifier from collecting water even when the desired humidity level is not attained.
Therefore, you might be asking: why is my Midea dehumidifier running but not collecting water? It could be the humidistat.
You might also want to check the filters. If they are clogged, the dehumidifier is not going to collect water. You might want to clean the filters or replace them.
Midea Dehumidifier Not Collecting Water: Advanced checks
These are the complex checks. You should only do them after doing the simple checks.
1. Failed compressor
If the dehumidifier is not collecting water, the first culprit is usually the dehumidifier compressor.
The work of the compressor is to circulate the refrigerant around the evaporator, which helps to extract the water from the air. If it fails, it is not going to extract moisture from the air.
The compressor can also stop working as a fail-safe feature. It has an overload protection function that stops it from working to protect the compressor motor from damage.
When you use the wrong power cord for the dehumidifier, the overload function can stop the compressor from working. Check that the power cord is not undersized or too long.
Also, you can find out whether the temperature is above 65 degrees Fahrenheit. If the temperature dips below that, the dehumidifier might not work.
2. Dehumidifier compressor runs but no water – Fan Motor
You could check your dehumidifier compressor and find that it is running just fine. Even the indoor temperature might be above 65 degrees Fahrenheit.
So, what could be wrong? Check the fan motor. If it is faulty, the dehumidifier will seem to be working, but it will not collect water.
The fan motor failure would then mean that the dehumidifier is not pulling in enough air. Remember, for the dehumidifier to collect water, it has to pull in the moist air from the room.
The refrigerant in the evaporator will then condense the moisture and it will be collected as water in the drip pan.
However, if the motor of the fan is not strong enough, it means less or no air is drawn into the dehumidifier.
When there is no moist air getting into the evaporator coils, it means no water being collected.
3. Dehumidifier capacitor failure
If your dehumidifier is not collecting water and you have verified that the fan motor and the compressor are fine, check the capacitor. If you are game, you can test it following the tips in the video below:
By the way, this is not an issue with the Midea dehumidifiers. It can occur with any brand name.
The capacitor and the compressor issue are connected because the capacitor is inside the compressor unit. Therefore, it is one of the main causes of compressor failure.
If you find that the overload device that protects the compressor is constantly tripping, the likely culprit is the capacitor.
If you have a problem of a Midea dehumidifier not collecting water, the checks outlined here can help.
Remember, runaway humidity at home causes the development of indoor allergens. You can experience signs of mold toxicity if exposed to this fungi for too long.
If your Midea dehumidifier shuts after running for a few minutes, it could have outlived its usefulness, especially if it has seen some years. If it has been faithful for at least 7 years, it’s time to let her rest.
If yours is new and still under warranty, you can send it back for repair.
