Fixing a Dehumidifier That is Running but Not Collecting Water

Your dehumidifier might be malfunctioning if it is running but not collecting any water. There could be several reasons why this is happening, including, but not limited to, a clogged drain, a dirty air filter, an overfilled bucket, or an issue with the compressor. Luckily, diagnosing and fixing dehumidifier problems is often straightforward.

Diagnosing the Problem

The first step when trying to fix a dehumidifier is to diagnose the issue. Start by checking for any visible blockage in the water collection bucket, such as dirt, leaves, or dust. Make sure the bucket isn’t overflowing, too, as that can prevent it from gathering more water. Also check the air filter, to make sure it is clear of debris and dust, as a clogged filter will prevent the dehumidifier from gathering water. If both the filter and the bucket are clean, you may have an issue with the compressor.

Steps to Fix a Non-Collecting Dehumidifier

  • Check the air filter, and replace it if necessary.
  • Clean out the water collection bucket, and make sure it isn’t overflowing.
  • Check for clogs in the drain hose, or any blockage around the air intake or exhaust ports.
  • If the issue persists, unplug the dehumidifier from the power outlet and clean the compressor coils.
  • If the problem still cannot be fixed, take the dehumidifier to a professional for servicing.
  • Troubleshooting Common Dehumidifier Problems

    • Clogged Filters: Change or clean the filter as often as recommended by the manufacturer.
    • Overfilling Tank: Automatically empty the collection bucket, or empty it when it gets full.
    • Dirty Compressors: Periodically clean the coils and fans of the compressor with a vacuum cleaner.
    • Clogs in the Drain Hose: Clear any obstructions in the drain hose and make sure it is properly attached to the dehumidifier.


    Fixing a dehumidifier that is running but not collecting water is often a simple process. Check the air filter and water collection bucket, and clean or replace them if necessary. Then check for clogs around the compressor or in the drain hose, and unplug the unit and clean its coils if you cannot find the source of the issue. If all else fails, it is best to take the dehumidifier to a professional for servicing.

    Personal Experience

    Why is my dehumidifier working but not collecting water?

    I have had a number of personal experiences when a dehumidifier is running but not collecting water. The main culprits are usually the collection tank, the filters or the fan motor. To identify what the issue is, I always start by checking the collection tank first. If the collection tank is stuck or blocked, it will usually prevent the water from being emptied correctly. Filtration systems also play a major role in the collection of water, so it’s important to check that these are regularly cleaned and are not worn out or damaged. Finally, if the fan motor isn’t running correctly, it could be preventing the dehumidifier from collecting water correctly. To diagnose this issue, I always listen out for a humming sound and check that the motor is running correctly.

    Once you have identified where the issue lies, it can usually be resolved quite quickly. In terms of the collection tank, simply unclogging the outlet usually solves the issue. To clean the filters, I usually remove them one-by-one and soak them in a sink of hot, soapy water. Finally, if the fan motor is the issue, it’s usually advisable to call a qualified engineer. If the motor is beyond repair, then you may need to purchase a new dehumidifier.

    In conclusion, dehumidifiers that are running but not collecting water can be easily fixed when you identify the source of the issue. Checking the collection tank, filters, and fan motor is usually the best place to start. After that, you should be able to easily diagnose and fix the problem.

    Frequently Asked Questions

    Why is my dehumidifier working but not collecting water?

    This could mean that the dehumidifier is not properly set up or there is an issue with the compressor. Check that the humidity settings are properly adjusted, as well as the ventilation levels. Also, make sure that the air filter is clean and free from dust or debris. If the issue persists, it is recommended to have the dehumidifier professionally serviced.

    How long does it take for a dehumidifier to start pulling water?

    It typically takes a dehumidifier a few hours to start pulling water from the air. The amount of time until it reaches optimal levels depends on the humidity in the room, the size of the dehumidifier, and how often it is used. Generally, it should take a few days to a few weeks for the dehumidifier to make a noticeable difference in the moisture.

    Will a dehumidifier always collect water?

    Yes, a dehumidifier will always collect water. The amount of water it collects depends on the relative humidity of the given space, but it will still collect water regardless. The device works by **** in the warm and humid air, cooling it, and then collecting the condensed water droplets before dispersing the drier, cooler air back into the room.

    How do you know if your dehumidifier is not working?

    To determine if a dehumidifier is not working, you can check for airflow. Place your hand above the device and feel for any air movement. Additionally, some models have settings that can be checked to make sure the dehumidifier is functioning correctly. If your dehumidifier is not working, it is best to contact a professional for assistance.

    Why is my dehumidifier running but not collecting water?

    The most likely reason your dehumidifier is running but not collecting water is that the compressor is faulty. The compressor is responsible for cooling the unit and allowing air to pass through the coils, allowing water to be extracted from the air. If the compressor is not functioning properly, the dehumidifier will not be able to collect any water. You may need to get a repair technician to check and replace the compressor if necessary.

    Do dehumidifiers always collect water?

    Yes, all portable dehumidifiers have a water collection container, such as a tank or bucket, which collects the water extracted from the air. This water is then either manually removed or pumped away as needed. Therefore, dehumidifiers always collect water.

    Why is my dehumidifier not pumping?

    Your dehumidifier may not be pumping due to a clogged or kinked hose, a height beyond 16 feet, or a malfunction in the system. To resolve, check the hose, measure the height, and power off, unplug the unit, and plug back in to reset it. If the issue persists, contact customer service for further assistance.

    How much water should a dehumidifier collect in a day in a basement?

    A dehumidifier can collect between 30 and 70 pints of water per day in a basement. It will often run constantly in excessively humid weather conditions, and may be able to collect more water during these times. To avoid any potential damage to the basement, it is important to monitor the dehumidifier’s output to ensure it is collecting the desired amount of water.

    Why is my dehumidifier compressor hot?

    The compressor of a dehumidifier can become hot due to restricted airflow. This can happen if the dehumidifier’s condenser (reheat) coil is dirty or clogged, or if the air filter is blocked. To cool the compressor, it is important to clean the condenser coil regularly and clear any potential obstructions to the airflow.

    Why is there no water coming out of my dehumidifier?

    The dehumidifier is not operating properly if there is no water coming out of it. This could be due to an issue with the power source, the settings, or a mechanical malfunction.
