Which one you use: Desiccant vs Compressor Dehumidifiers

Before diagnosing the problem, it’s important to determine which type of dehumidifier you are using, there are two main types of dehumidifier in the market.

  • Desiccant Dehumidifier
  • Compressor Dehumidifier

Desiccant dehumidifiers use a special material such as silica, Zeolite or another desiccant to absorb and collect the moisture in the air. This type of dehumidifier is beneficial for those who want a lower energy bill due to its low-energy consumption.

Compressor dehumidifiers utilize a cold coil system to extract moisture from the air. This type of dehumidifier may be more efficient for larger spaces, but it also uses more energy than a desiccant dehumidifier.

When a desiccant dehumidifier isn’t functioning properly, It could also be the case that the desiccant material such as silica, Zeolite or another desiccant needs to be replenished or changed out. In some cases, the fan may be blocked so it’s important to check for and remove any obstructions that could cause the fan to malfunction.

When a compressor dehumidifier isn’t working properly, it is usually because the refrigerant needs to be replenished or changed out. It could also be that the fan or coil are blocked and need to be cleared of obstructions, you also have to check all this points.

Key point of Dehumidifier not collecting water:

  • Check if the float switch is stuck
  • Check if the drain pipe is clogged
  • Clean the air filter
  • Clean the dehumidifier’s coils
  • Check fan motor
  • Check if the evaporator coil is frozen
  • Check if the compressor overload is tripped
  • Check if the run capacitor is bad
  • Check if the relay is stuck
  • Check if the fan motor is not working
  • Check if the compressor is not working

1. Check if the float switch is stuck:

The float switch is an important component of your dehumidifier as it helps to monitor the water level in the collection tank. When the water level reaches a certain point, the float switch triggers and shuts off the fan so that no more water can enter the tank.

If this float switch gets stuck or fails, your dehumidifier will not be able to collect any further water, leading to problems with humidity levels in your home. To check if your float switch is stuck, locate it in your dehumidifier’s collection tank and remove it gently. Make sure the contacts are clean and free from debris, then replace it back into its receptacle and try running your dehumidifier again.

2. Check if the drain pipe is clogged:

The drain pipe of your dehumidifier is responsible for carrying away the collected water. If this drain pipe becomes clogged or blocked, it can prevent the system from collecting any further water and result in issues with humidity levels in your home.

Checking the dehumidifier drain system

To check if your drain pipe is blocked, start by removing it from the unit and inspecting it for any blockages or debris that may have built up. You can use a damp cloth to gently wipe out the inside of the pipe to clear away any obstruction. Once you’ve done this, replace the pipe back into its receptacle and try running your dehumidifier again.

3. Clean the air filter:

Your dehumidifier’s air filter is responsible for trapping dust and dirt particles as air passes through the system. Over time, this filter can become clogged or dirty, preventing it from effectively filtering the air.If your air filter is not working properly, it can cause your dehumidifier to stop collecting water, leading to problems with humidity levels in your home.

Checking the dehumidifier if it is dirty

To clean the air filter on your dehumidifier, start by unplugging the unit from power and removing the filter. Gently brush away any debris that has built up on the surface of the filter using a damp cloth or soft brush. Once all of the accumulated debris has been removed, rinse off any remaining dirt under running water before allowing it to air dry.

Once it’s completely dry, replace the filter back into its receptacle and try running your dehumidifier again. If this does not resolve the issue, you may need to replace the filter with a new one.

4. Clean the dehumidifier’s coils:

The coils in your dehumidifier are responsible for dissipating heat from the system. If these coils become dirty or clogged, they can cause the air inside the unit to become too hot, preventing it from collecting any further water and leading to problems with humidity levels in your home. To clean the dehumidifier’s coils, start by unplugging the unit from power and removing the filters.

Cleaning the dehumidifier coil

Use a soft brush or vacuum attachment to carefully remove any dust or dirt that has built up on the surface of the coils which also causes smell in dehumidifeir. Once all of the debris has been removed, rinse off any remaining dirt under running water before allowing it to air dry.

Once it’s completely dry, replace all of the filters back into their receptacles and try running your dehumidifier again. If this does not resolve the issue, you may need to replace the coils with new ones.

5. Check fan motor:

If your dehumidifier is still not collecting water after cleaning the coils, then it could indicate a problem with the system’s fan or blower motor. To check if this is the case, start by unplugging the unit from power and inspecting the fan for any signs of wear or damage. If it appears to be functioning properly, then you should check all of its electrical connections for loose wires or damaged components. You can also check for obstructions in the air intake vents that may be preventing air from flowing through the fan correctly.

6. Check if the evaporator coil is frozen:

If your dehumidifier is not collecting water, it could be due to a frozen evaporator coil. The evaporator coil is responsible for cooling the air passing through the unit, and if it becomes too cold, it can cause the moisture in the air to freeze on its surface. This will prevent any further water from being collected and lead to problems with humidity levels in your home.

Dehumidifier Freezing Up

To thaw out a frozen evaporator coil on your dehumidifier, start by unplugging the unit from power and adjusting the temperature controls so that they are set at a higher level than before. Then leave the unit alone for several hours to allow it to slowly warm up and thaw out any ice that may have built up on its surface.

Once the coil has had time to thaw out, try running your dehumidifier again and check for any signs of water collecting in the tank. If this does not resolve the issue, then it could indicate a more serious problem with the system’s electrical components and you may need to call an HVAC professional for further assistance.

7. Check if the compressor overload is tripped:

If your dehumidifier is not collecting water, it could be due to a tripped compressor overload. The compressor overload is a safety feature that shuts off the system’s power when it senses too much heat or current being drawn from the motor. This can happen if there is an electrical issue or a blockage in the air intake vents preventing air from flowing properly.

checking the compressor of dehumidifier

To check if this is the case, start by unplugging the unit from power and removing any obstructions in the air intake vents. Then, check all of its electrical connections for loose wires or damaged components and try running your dehumidifier again. If this does not resolve the issue, then you may need to reset the compressor overload by pressing the reset button located on the side of the unit.

8. Check if the run capacitor is bad:

When a dehumidifier is not collecting water, it could be due to a bad run capacitor. The run capacitor helps the motor start and maintain operation by providing it with additional power when needed. If the run capacitor has failed or been damaged in some way, then the motor will likely not be able to draw enough current to operate correctly and your dehumidifier won’t be able to collect water.

checking the capacitor of dehumidifier

To check if this is the case, start by unplugging the unit from power and inspecting its wiring for any signs of damage or corrosion. You can also use an ohmmeter to test continuity between each terminal of the run capacitor and make sure they are all within acceptable ranges. If you find that any of the terminals are not functioning correctly, then you may need to replace the run capacitor altogether.

9. Check if the relay is stuck:

If your dehumidifier is not collecting water, it could be due to a stuck relay switch. The relay switch is responsible for controlling the power supply of the motor and if it becomes stuck in one position, then it can prevent the motor from drawing enough current to operate correctly.

To check if this is the case, start by unplugging the unit from power and inspecting its electrical connections for any signs of damage or corrosion. If you find that all of the wiring appears to be in good condition, then use an ohmmeter to test continuity between each terminal on the relay switch and make sure they are all within acceptable ranges.

10. Check if the fan motor is not working:

When a dehumidifier is not collecting water, it could be due to an issue with the fan motor. The fan motor is responsible for circulating air over the evaporator coils and if it fails to work correctly then this can prevent the unit from collecting water properly.

To check if this is the case, start by unplugging the unit from power and inspecting its wiring for any signs of damage or corrosion. You can also use an ohmmeter to test continuity between each terminal of the fan motor and make sure they are all within acceptable ranges. If you find that any of the terminals are not functioning correctly, then you may need to replace the fan motor altogether in order to resolve the issue.

11. Check if the compressor is not working:

It could be due to an issue with the compressor. The compressor is responsible for pressurizing the refrigerant that flows through the system and if it fails to work correctly then this can prevent the unit from cooling properly and collecting water into its reservoir.

To check if this is the case, start by unplugging the unit from power and inspecting its wiring for any signs of damage or corrosion. You can also use an ohmmeter to test continuity between each terminal of the compressor and make sure they are all within acceptable ranges.

If you find that any of the terminals are not functioning correctly, then you may need to replace the compressor altogether in order to resolve the issue.

Check the Humidity Levels:

A dehumidifier works by removing excess moisture from your home’s air. It does this through a process of evaporation, and it needs a certain level of humidity in order to do its job correctly.

If the humidity levels within your home are too low (below about 40%), then the dehumidifier won’t be able to collect any water at all. In order to ensure that your dehumidifier is working properly, it’s important to regularly check the humidity levels in the rooms where you have it running.

You can do this with an inexpensive hygrometer or even just using a glass or plastic cup filled with warm water—the condensation on the outside of the cup will tell you what the relative humidity is. If the humidity levels are too low, then increasing your home’s ventilation can help (using window fans, exhaust fans, etc.

How do you know if your dehumidifier is not working?

If you’ve got a dehumidifier in your home, it’s important to make sure that it’s working properly. After all, a malfunctioning dehumidifier can be both ineffective and potentially cause water damage. So how do you know if your dehumidfier isn’t working?

The first thing to do is check the relative humidity of your home. If the relative humidity is still high, then it’s likely that your dehumidifier isn’t functioning correctly. A good way to check this is to use a hygrometer, which will measure the humidity in your home so you can make sure it’s at an acceptable level.

If the relative humidity remains high despite running your dehumidifier for a period of time, then it’s likely that there is an issue with the unit. There could be a number of issues causing your dehumidifier to not work, such as clogged filters or problems with the fan. It’s best to contact a professional if you suspect there may be an issue with your dehumidifier so they can diagnose and repair the problem.

Electronic Control Board or PCB Assembly:

The electronic control board, or PCB, is a crucial component of modern dehumidifiers. It is responsible for sensing the ambient room temperature and humidity levels and activating the compressor or fan motor to regulate air quality. It can detect when the relative humidity rises above the set level and turn on the compressor/fan motor to remove moisture from the air.

The control board also contains sensors that monitor the performance of the system, as well as relays that turn on or off compressor/fan motor. If the electronics are malfunctioning, it may prevent the unit from pulling water from the air and cause problems with air quality.

A voltage test using a multi-meter can help diagnose issues with the electronic control board, such as defective relays or faulty sensors. If the control board is malfunctioning, it should be replaced to ensure proper operation of the dehumidifier. Making sure the electronic control board is working properly can help you keep your home comfortable and healthy by providing clean, dry air.  

The Capacitor Is Broken:

Capacitors are an important component of many electric appliances and they store energy in their electric fields so you can get the performance that you expect from your device. Without a working capacitor, the fan motor won’t be able to suck in air from the environment, and no water will be collected in the reservoir.

Fortunately, there are ways to troubleshoot this problem without having to call in a professional. You can start with testing for continuity using a multimeter if you have one on hand. This way, you can easily determine whether or not the capacitor is indeed broken.

Circuit Board Is Dead:

Nobody likes to have their household appliances break down, especially when it comes to expensive and vital items like a dehumidifier. A dehumidifier is designed to help keep your home free of excess moisture and mould, so when yours suddenly stops collecting water, it can be quite the inconvenient surprise.

Repair the bord of dehumidifier

One of the most common causes of this issue is a dead circuit board. A large power surge, usually from an electrical storm, can fry the board and make your appliance completely useless until it’s repaired or replaced.

Solution: In this case, you should check to see if your dehumidifier is still under warranty – many brands offer coverage for such events. If so, then you may be able to get your repairs done for free.

If not, you’ll need to take the cost of repairs versus the cost of purchasing a new model into consideration.

Conclusion:

The lack of water collection in a dehumidifier is typically caused by a clogged or blocked drainage hose. This can be fixed by either cleaning or replacing the hose. If this does not solve the problem, then there could be an issue with the compressor or fan motor that needs to be addressed by a professional technician. Taking care of your dehumidifier and regularly checking it for any potential blockages or other issues will help ensure that you get the most out of it for years to come.
