What Does The E5 Error Mean for Hisense Portable Air Conditioner?
The E5 error code usually means that the water collection tank simply needs to be poured out.
However, in some cases, users of the Hisense portable air conditioner may do this and still see the E5 error code, which could mean that there are other issues that are triggering the E5 error.
There are many components that make up your Hisense portable air conditioner, such as the condensation drain hose, the air filter, and even the evaporator coils.
As useful as all of these components are they can also have problems functioning properly when they are dirty, clogged, or even frozen. It is important to get to the root of the problem so that you will not have to waste your time attempting other solutions or potentially breaking the air conditioning unit while trying to figure out what is causing the error issue.
1. Water Collection Tank Needs To Be Emptied
The most common cause for the E5 error code on your Hisense portable air conditioner is that the water collection tank needs to be emptied.
An air conditioner needs a water collection tank because it is a fundamental component of the unit’s condensation process.
When the air conditioner is running, it cools down the hot air inside a building or room by passing it through a series of coils that contain refrigerant. As the hot air comes into contact with these coils, it causes the refrigerant to condense and turn into a liquid.
This liquid then drips into a water collection tank, which is typically located outside of the unit; however, on the Hisense portable air conditioner, it is held inside the unit toward the bottom.
The water collection tank serves several important functions. First, it acts as a reservoir for the condensate that is produced by the air conditioner.
This condensate is then used to help cool down the refrigerant as it flows through the coils, making the air conditioning process more efficient.
Additionally, the water collection tank helps to prevent the condensate from overflowing and causing damage to the unit or the surrounding area.
The water collection tank also prevents the condensate from being discharged into the environment as it can be recycled and used as a source of irrigation water. Another benefit of having a water collection tank is that it allows the air conditioner to run continuously without interruption.
Fix – Empty The Water Collection Tank
If you live in an area with exceptionally high humidity, then the reason why you are seeing the E5 error code is likely because the water collection tank is full.
This is the most common reason why a Hisense portable air conditioner will show the E5 error code. Luckily, this is a fairly quick and easy fix to perform on an air conditioning unit, especially the Hisense portable air conditioner.
It should be noted that if you just recently purchased your Hisense portable air conditioner or do not live in an area with high humidity, then you should not be encountering the E5 error code unless there is an issue with a different component or even the unit itself might be faulty.
If you believe that the reason why you are seeing the E5 error code on your Hisense portable air conditioner is that the water collection tank needs to be emptied, then you will want to empty the reservoir.
You can start by unplugging the Hisense portable air conditioner from the electrical outlet, then place a sheet pan or small bowl below the pour nozzle located at the bottom of the air conditioner.
Once you are ready, twist open the pour nozzle and let the water drain into the sheet pan or bowl, then close the pour nozzle and empty the drained water into an appropriate drain or spot. You may have to repeat this procedure a couple of times to empty all of the water.
You may also have to prop up the air conditioner and tilt it towards the drain nozzle to make sure all of the water is drained out of the water collection tank.
Once you believe that you have drained all of the water from the water collection tank, then you can carefully plug the power cord back into the outlet and turn your Hisense portable air conditioner back on to see if the E5 error has been cleared as it should be after draining the water.
2. Condensate Drain Line Clogged
Now, we have talked about the water collection tank and how that can trigger the E5 error code on your Hisense portable air conditioner; however, there is also a component known as the condensate drain line or pipe.
This component is responsible for catching all of the water produced by the air conditioning unit and directing it to the water collection tank. You may assume that since this drain line directs the water that it would remain clean and clear.
However, the condensate drain line can become clogged by particles and debris that are within the water produced by the air conditioning unit.
Fix – Clean and Clear The Condensate Drain Line
As previously depicted, the condensate drain line or pipe for the Hisense portable air conditioner can become clogged with particles and debris that are in the water produced by the air conditioning unit.
Depending on the model of the air conditioner you have, you should be able to unplug the Hisense portable air conditioner and both clean and clear out any debris that may be clogging the condensate drain line.
This should be easily done by wearing cleaning gloves and clearing out any blockages, then you can use a soft cloth along with warm water and soap to clean the condensate drain line.
3. Dirty Air Filter
Now, the keyword in “air conditioner” is the word “air,” which means that your Hisense portable air conditioner needs to be able to circulate the air through the unit.
However, if the air filter on your Hisense portable air conditioner is dirty, then the machine will not be able to effectively circulate the air.
Furthermore, if the air filter on your Hisense air conditioner is dirty or blocked up, then it will certainly struggle to provide cool air and can result in the air conditioner displaying the E5 error code.
A dirty air filter can lead to your air conditioning unit overheating and can even cause the compressor to falter.
In order to get rid of the E5 error code and to keep your Hisense portable air conditioner running efficiently, you will want to clean the air filter regularly.
Fix – Clean The Air Filter
As previously depicted, a dirty air filter is not good for your air conditioning unit, which means you will want to make sure that the air filter for your Hisense portable air conditioner is clear and clean.
You can find the air filter compartment on the backside of your Hisense portable air conditioner.
You can open the air filter compartment by pressing on the pressure lever at the top of the air filter compartment cover, which will release the cover for removal.
Now you can take the air filter off of the compartment cover and shake the air filter out of any dust, dirt, or debris.
After you have shaken out the air filter, you can also rinse out the air filter with water and make sure there is no dust or debris on the air filter.
After you have shaken off and rinsed out the air filter, then you can place the air filter on a drying rack to completely dry.
Once the air filter is entirely dry, then you can place the air filter on the air filter compartment cover and press the air filter and cover back into place on the back of your Hisense portable air conditioner unit.
4. Possible Refrigerant Leak
A significant problem with your Hisense portable air conditioner could be a refrigerant leak. Refrigerant is necessary for the AC unit to function and control the room’s temperature. Your air conditioner cannot adequately cool the space without refrigerant.
Additionally harmful to your health, refrigerants should only be handled by trained personnel. Your air conditioner may experience issues due to a refrigerant leak, such as a frozen AC unit, which may have led to moisture building up in the drain pan.
A refrigerant leak could certainly cause your Hisense portable air conditioner to show the E5 error code since the system is detecting an issue in the unit’s functionality.
Fix – Contact a Professional or Replace The Unit
If you believe that your Hisense portable air conditioner has a refrigerant leak, then you should not attempt to fix the issue yourself.
Refrigerant is a harmful chemical and should only be handled by a licensed professional. You can also contact a Hisense technician that can help you figure out if your Hisense portable air conditioner is leaking refrigerant or not and where to go from that point.
If you are certain that your Hisense portable air conditioner has a refrigerant leak and do not want to try to get the unit repaired, then you can see about getting a replacement for your unit, which may be on the warranty (if you have one).
5. Faulty Unit
Not all machines are made perfect, which may be why your Hisense portable air conditioner is still showing the E5 error code.
It is certainly possible that you have purchased a faulty unit, which means that it was doomed from the start. This is very unfortunate and inconvenient but it would not be the first time or the last.
Fix – Contact Hisense
If your Hisense portable air conditioner is under warranty, then you will want to contact Hisense and go from there.
If you are certain that your air conditioner is not under warranty, then you can still contact Hisense if you purchased your unit from them directly.
