Have you noticed that your dehumidifier isn’t collecting water as expected? If so, this comprehensive guide will help you understand why this might be happening and how you can fix it. We’ve also covered how to clean the coils of a refrigerant dehumidifier and how often you should be doing so.
Troubleshooting Dehumidifier Issues
There are several reasons why your dehumidifier might not be collecting water. Here are some of the potential causes and their solutions.
Problem | Cause | Solution |
---|---|---|
Dehumidifier not working | Power issues | Reset the dehumidifier by disconnecting power for 30 seconds and reconnecting it. Reset the control settings. |
Insufficient airflow | Faulty fan motor | If room temperature is over 65 degrees Fahrenheit and little or no air is coming through the grille area, remove the cover and check the fan area. |
Dehumidifier not collecting water | Defective compressor capacitor | If room temperature is over 65 degrees Fahrenheit and the overload device keeps tripping, the compressor capacitor might be defective. |
Water buildup inside the dehumidifier | Clogged drain pipe | Ensure the drain pipe is not clogged. |
Dehumidifier not collecting water | Target humidity already reached | Check that the target humidity is set to a level that is appropriate for the room. |
Dehumidifier not collecting water | Low room temperature | Ensure the room temperature is above 65 degrees Fahrenheit. |
Remember, if none of these steps work, it might be necessary to contact a professional for further assistance.
Cleaning the Coils on a Refrigerant Dehumidifier
Keeping the coils of your dehumidifier clean ensures efficient operation. Here is a step-by-step guide on how to clean the coils:
- Turn off the dehumidifier: Before cleaning the coils, turn off the dehumidifier and unplug it from the power source.
- Remove the filter: Use a vacuum to suck out any dirt and debris from the filter.
- Clean the coils: Locate the coils and use a soft brush with a spray detergent or mix of water and vinegar. Rinse off the residue. If there are mold spores, spray white vinegar or bleach and let them sit for 30 minutes.
- Dry the coils: Let the coils dry completely before turning the dehumidifier back on. You can speed up the drying process by placing the coils near a radiator or other heat source.
- Replace the filter: Once the coils are dry, replace the filter and turn the dehumidifier back on.
Remember, frequent coil cleaning can improve the overall effectiveness of your dehumidifier.
Frequency of Coil Cleaning
The frequency of coil cleaning in a refrigerant dehumidifier varies depending on the environment and the frequency of usage.
Recommendation |
---|
At least once a year |
At least once a year, more frequently in humid environments |
At least once a year, more frequently for frequent use or in humid environments |
In general, it is recommended to clean the coils on a refrigerant dehumidifier at least once a year. However, for those who use their dehumidifier frequently or live in a humid environment, more frequent cleaning may be necessary.
Keeping your dehumidifier in good condition requires both proper troubleshooting when issues arise and regular maintenance. Ensure you stay on top of these to enjoy a comfortable, humidity-controlled environment.

Advanced Troubleshooting Tips
If the issues persist after trying the basic troubleshooting steps and routine cleaning, you might need to take a closer look at the dehumidifier. Here are a few more advanced measures you can take:
Checking the Humidistat
The humidistat in your dehumidifier may be faulty, causing it to incorrectly read the humidity level in the room. To check this, turn the dehumidifier to the highest humidity setting and see if it runs. If it does, the humidistat might be the problem and need replacement.
Examining the Refrigerant Level
Like your home’s air conditioner, your dehumidifier uses refrigerant to remove moisture from the air. If the dehumidifier isn’t collecting water, it might be low on refrigerant. This issue is best left to professionals, as handling refrigerant requires special skills and tools.
Assessing the Temperature Sensors
Some dehumidifiers have temperature sensors that stop the unit from operating if the temperature is too low. If this sensor malfunctions, it might incorrectly sense a low temperature and prevent the unit from running. Replacing a faulty temperature sensor should solve the problem.

Regular Maintenance for Optimal Performance
Keeping your dehumidifier in peak condition goes beyond fixing problems as they come up. Here are some regular maintenance tasks that can help you prevent common dehumidifier issues:
Regularly Check for Dust and Dirt
Dust and dirt can clog the dehumidifier’s filters and coils, causing the unit to work harder and possibly leading to other issues. Regularly check these parts and clean them as necessary to prevent dust buildup.
Inspect the Water Bucket Regularly
Make sure to inspect and clean the water bucket regularly to prevent mold and mildew growth. Any blockage can cause the water bucket to overflow or prevent the dehumidifier from working.
Replace the Filter Regularly
The filter plays a crucial role in keeping your dehumidifier running smoothly. Replace it regularly following the manufacturer’s recommendations. If the filter is reusable, clean it as per the manufacturer’s instructions.
In conclusion, maintaining your dehumidifier requires a mix of regular cleaning, timely troubleshooting, and staying alert for any signs of malfunction. When properly cared for, your dehumidifier can provide you with years of efficient service, maintaining a comfortable and healthy humidity level in your home.
My Dehumidifier is Not Collecting Water
If you find that your dehumidifier is not collecting water, it might be due to a variety of issues. It is common for people to ask, “Why is my dehumidifier blowing cold air and not collecting water?” This might be due to a problem with the refrigeration system, specifically the compressor.
The compressor is a vital part of your dehumidifier’s functionality. Its primary function is to circulate the refrigerant, which is what helps to remove moisture from the air. When the compressor is not working, the dehumidifier will fail to collect water. In some cases, the dehumidifier compressor might feel hot but produce no water. This usually indicates an issue with the refrigerant or the compressor itself.
One question that comes up frequently is, “Will a dehumidifier always collect water?” The simple answer is no. The amount of water your dehumidifier collects depends on the relative humidity in the room and the setting you choose. When the desired humidity level is reached, the dehumidifier will stop collecting water.
If your dehumidifier is still not collecting water despite troubleshooting, you may need to search for “dehumidifier repair near me” and get a professional to inspect it. This is particularly recommended if you suspect an issue with the compressor or refrigerant, as these involve complex parts of the device that require expert handling.
Danby Dehumidifiers Frequently Asked Questions
If you’re using a Danby dehumidifier and it’s not collecting water, there are some frequently asked questions and their answers that can help you troubleshoot:
1. My Danby dehumidifier isn’t collecting water. What could be the problem?
A number of factors might cause this. Check if the compressor is running, ensure that the room temperature is above 65 degrees Fahrenheit, and verify that the desired humidity level hasn’t been reached. If everything seems fine and the dehumidifier still isn’t collecting water, the problem might be more complex and require professional help.
2. Why is my dehumidifier blowing cold air?
The dehumidifier blows cold air when the compressor is running but it’s not collecting water. This could indicate a problem with the refrigerant or the compressor.
3. My dehumidifier isn’t collecting water but the compressor is hot. What does this mean?
When the compressor is hot but the dehumidifier is not collecting water, this could indicate a problem with the refrigerant level or a malfunction in the compressor. In such a case, it’s best to consult a professional.
By understanding how your dehumidifier works and keeping a keen eye on its performance, you can prevent minor issues from becoming major problems. Regular maintenance, timely troubleshooting, and professional assistance when needed will help ensure your dehumidifier keeps your home comfortable and free from excessive moisture.
