13 Reasons Why Your Dehumidifier Leaking Water. How To Fix It.

When you’re running a small space like a home office, your dehumidifier is a very important piece of equipment. If you’re not using your dehumidifier correctly, it could be costing you money, and it’s potentially dangerous. There are many reasons why your dehumidifier leaking water, and this article will explain what the different types of leaks are, and how you can fix them.

As you continue to read this article, it will go over each of the potential reasons your dehumidifier is leaking above. Along with that, it will also give a quick rundown of how you can go about fixing each of those issues.

What Is A Dehumidifier?

A dehumidifier is a machine that removes humidity from the air. It does this by drawing in and cooling air, and then blowing out and heating the air, and this is why it’s called a dehumidifier. Dehumidifiers are a little bit like your home’s air conditioner, except it’s much more powerful.

The easiest way to think of a dehumidifier is to think of it as a powerful fan. Your dehumidifier will draw in cool air from outside your home, and blow out warm air into your home.

Is-Your-Dehumidifier-Leaking

If you’re in a hot, humid climate, you’ll need to use your dehumidifier more frequently than if you live in a cooler area. It’s not unusual for a dehumidifier to run for at least a few hours each day.

It uses internal heating to regenerate the desiccant present inside to repeat the cycle of moisture absorption repeatedly. So, these dehumidifiers are better used in damp rooms like bathrooms for basements rather than living rooms and bedrooms. Desiccant dehumidifiers: These work by removing the moisture via a desiccant wheel, which is then dried with an internal heater. The desiccant dehumidifier is quieter and tends to last longer than compressor dehumidifiers. You don’t have to empty a disposal tank, and it doesn’t require refrigerant.

Why Is My Dehumidifier Leaking Water? And How To Fix It

Before we start troubleshooting your dehumidifier that is leaking It is essential that you know how to operate your appliance correctly.

There are numerous small operational mistakes that could cause leaks. Avoid many problems by making sure your dehumidifier been properly installed and set to the ideal setting, and is in the right place.

If you’re new to the dehumidifier you should go through our article on how to use the Dehumidifier. This article will provide all that you should know in order to start using the new device.

If you have older appliances or problems that are not related to improper installation, continue studying to learn about the 12 most likely causes for leaks in dehumidifiers and the best way to resolve these issues.

1. Misaligned Water Collection Bucket

Portable dehumidifiers as well as those not integrated into homes all come with a reservoir for collecting water. This bucket is used to hold water in case the drainage hose isn’t being used.

If the bucket is placed improperly or misplaced this can cause the unit to leak.

To correct a misaligned Water collection bucket

  1. Disconnect the device.
  2. Unlock the reservoir compartment to reveal the bucket of water.
  3. Get rid of the bucket and empty it of any water in it. You might also have to wash any pooling water within the unit.
  4. Make sure to replace the bucket of water according to the instructions included with your unit.
  5. Make sure you have the bucket level, secured in the proper position in addition, ensure that the switch for overflow (usually an adjustable device that is positioned inside the bottom of the bucket) is in the correct position.

If that was the case then you shouldn’t observe any additional water pools under the unit when you turn the unit back on.

Make sure you remove your water bucket regularly and store the dehumidifier an area that isn’t pushed around to ensure that the issue doesn’t come back.

2. Cracked Water Reservoir

As we’ve mentioned earlier that a dehumidifier depends on a variety of parts that are all in sync. If you’re unsure of the way a dehumidifier functions it is a good idea to research. The article we have written, What is a Dehumidifier? Perform is a good beginning point.

Sometimes, the issue can be as easy like one of the complicated pieces breaking. The most likely culprit for it is the bucket for water. If older units are that are exposed to extreme temperature changes the bucket for the water reservoir may crack, causing leaks.

For a quick check of leaks in the reservoir of your water:

  1. Disconnect the device.
  2. Unlock the reservoir compartment and reveal the water bucket.
  3. Remove the bucket and look for any blemishes or cracks. There are cracks that may be too small for you to notice and it is useful to put the bucket with water and look for leaks.

If you discover an issue with your reservoir bucket, the best solution is to call the manufacturer to request replacement. It is possible to repair the crack but it’s only an immediate solution. It is likely that you will have to deal with the same problem in the near future.

3. Blocked Hose

If your dehumidifier is connected to a drain pipe, the cause of your leak could be blocked hose. The debris can get in from the draining side, and is more likely when it is connected outside, where rodents and insects are attracted to the system.

Check your drain hose to see if it is obstructions:

  1. Unplug the device.
  2. Take the drainage hose out of the point where it connects to the unit.
  3. Bring the hose to the outside and put your garden hose on the other end.
  4. Switch the garden hose to full blast then let it flow through until it flows clear from the other end.
  5. If the blockage isn’t able to be removed the hose, you can soak it in a sink containing hot soapy water, and try to do it again.

If water is flowing through the hose with no issue and no water comes out, then the issue is most likely not caused by an obstruction in the hose.

4. Bent Drain Pipe

The blockage isn’t the only reason that a drain pipe could leak. If the hose is bent or bent it may cause water to flow back into the reservoir before leaking to the floors.

The drainage hose pipe you choose to use should be able to drain into the floor or out to the outside via the most efficient route, and should not have any tight twists or twists.

Bent Drain Pipe example

To examine your drainpipe for Kinks, follow it from the rear of the unit to the drain area. Check for sharp bends or places in which the hose turns around itself. If you find any of these signs then take the drain hose off and reposition it in a flat position and connect it.

It is possible to require stabilizers or other objects to keep the hose and then widen it to stop the kink from repeating itself.

5. Small Water Pipe

Sometimes the issue is more to have to do with the hose getting bent and more to have to do with the fact that the drainage hose’s isn’t big enough to accommodate the output that your humidifier produces.

In extremely humid conditions it is possible for the appliance to create water faster than what the drain line is able to accommodate, which causes the water to drain back in the unit. You’ll know this is the issue when you observe a constant strong stream of water gushing from the drain hose and the appliance continues to leak. in the process of leaking.

Depending on the dehumidifier you have the fix may not be a simple solution.

A majority of the large dehumidifiers feature an 3/4 ” drainage line for the hose. They can be able to accommodate the same size of hose as your typical garden hose. They typically have hoses that are slim which use a large hookup. If you’re having issues with one of these smaller-diameter hoses try swapping the hose to a larger alternative and see if it alleviates the issue.

Certain personal and portable dehumidifiers come with smaller hose hookups, typically half ” in diameter, or smaller. In this case, with your unit and you suspect that a smaller hose is the cause, your best bet is to buy a new dehumidifier designed to be used in humid conditions.

6. Loose Hose Fitting Cap

Even if your hose’s capacity is sufficient for draining the dehumidifier, it could be leaking if the connections aren’t secured.

If you find an issue with the cap that connects your hose joins the dehumidifier, it is likely to be the issue.

 Loose Hose Fitting Cap example

To repair a leaky hose fitting cap:

  1. Remove the plug from the appliance.
  2. Take the drain hose off.
  3. Clean the fittings on the unit as well as the hose.
  4. A lot of units come with an o-ring made of rubber that can be fitted to the male end of the connection. If it isn’t there you can get an equivalent.
  5. Connect the hose again to the fitting and make sure it is tight until it has stopped turning. Be certain to prevent the fitting from crossing-threading.
  6. If the fitting is running, you may have to use plumber’s tape and then tighten it.

If the fitting is still leaking It is most likely that the problem is caused by a defective fitting. It is necessary to purchase an additional fitting from the manufacturer in case this is the situation.

7. Drain Hose Coiled Vertically

The majority of portable and personal dehumidifiers are based on gravity to transport water from the tank to via the drain pipe. If there’s any vertical lift or coiling within the hose, water will re-enter the unit, creating the unit to leak.

If you have vertical coiling within your hose, then you’ll have to tie the line to the floor at the ends to keep it level and straight.

If you notice an upward gain in the hose that is visible between your unit and point of drainage You will have to rectify it. The easiest method to do this is to lift your dehumidifier from the ground by using blocks, cinderblocks, or even a table. You can also place your unit in a counter or a shelf.

If it’s not possible to put the dehumidifier lower than the point where it drains then you’ll need to install an drainage pump. Certain units are made to accommodate this requirement and in this case, the manufacturer must offer the correct pump for your particular setup. In the case of other models you’ll need to connect the general-use condensate pumps to your drainage system.

8. Disconnected Drain Hose

It could be something that is obvious However, typically the reason for a dehumidifier to leak is the result of a broken drainage hose. In new models the reason is that the drainage hose wasn’t connected at all.

It is possible for a functional hose to be cut off or loosening in time. This is particularly likely if the hose is exposed fluctuations in temperature.

Before making any more complicated repairs, make sure to make sure to check the drainage hose connector to the rear of the unit. Also, make sure the hose’s connector is securely secured to the floor drain or on the outside.

9. Hose Is Too Long

Horizontal gain can be an issue for humidifiers that are pumpless. If the drain hose is not long enough, water will collect and back up in the unit, leading to leaks.

The length of hoses is often an issue for dehumidifiers that are used in basements since the drain point is usually distant from where the dehumidifier is.

If you purchase a high-quality dehumidifiers in your basement will save you from this problem. They come with special characteristics that make them ideal for sub-ground levels of your home, such as built-in pumps that are able to drive water against gravity to allow for proper drainage.

If you have a dehumidifier that is leaking because the length of the hose is excessive there are three options to address the problem. You could move your unit to a drainage zone and then purchase a new pump as described in the section on vertical coiling above, or purchase an alternative dehumidifier sufficient to work in a basement.

10. Jammed Pump

If your dehumidifier features an engine but it is leaks from an overflowing water drain hose or reservoir it could be an overloaded pump.

The pumps are most likely to fail due to the fact that they are clogged by particles.

To correct this problem:

  1. Unplug the appliance and pump.
  2. Lift the pump.
  3. Clean the pump in the manner described in the directions of the manufacturer.
  4. Replace the pump, then plug everything back into.

Check that the pump is properly installed. There are many dehumidifiers with sensors that stop the pump from working in the event that the hose isn’t installed correctly or the pump isn’t properly in the correct position.

The leak issue you are experiencing should be resolved as long as everything is as it should be and your pump is not blocked.

11. Frozen Coils

The dehumidifier’s coils may freeze due to many causes. All of them can cause leaks to develop.

The most commonly cited reason is the fact that the unit is running under low temperature. Any temperature that is lower than 65 degrees could cause dehumidifier coils and pipes to freeze up. A lot of dehumidifiers come with a built-in thermometer that shuts it off if temperatures drop to a low level. If your unit isn’t equipped with the feature you’re looking for, then you’ll be left with only one option: turn off the unit by hand.

The problem with the parts of the dehumidifier may lead to the coils becoming get frozen. If the motor of the fan or blower wheel is damaged it won’t have enough airflow to prevent the coils from becoming cold. It will be obvious the issue if it is difficult to detect the fan’s movement when the unit is in operation.

Other possibilities include the malfunctioning of a humidistat as well as a bi-metal thermostats. Check your owner’s manual to learn more about these components and the best way to determine whether they’re functioning correctly.

12. Malfunctioning Overflow Switch

Modern dehumidifiers come with an auto-off feature that will shut down the unit when the water bucket exceeds its capacity. If this feature isn’t working the unit could overfill or overflow during use.

In the event that the leak occurs suddenly and persists to get worse after the machine is operating It could be due to the malfunction of an overflow switch.

The most popular configuration for dehumidifier switches that has an attached floaty which rises along with the water in the bucket for collection. When the water is at the level of its highest that the floaty rises, it activates the switch, which turns the device off.

This switch may be faulty in a variety of ways.

The issue can be quite simple, such as the floaty for the overflow not being installed correctly or not reset when the water bucket has been reinstalled. Refer to the owner’s manual for your unit to determine the proper location and placement of the switch for overflow.

It’s also possible for the switch to be damaged or burned out. If this occurs, you’ll require spare parts through the manufacture or purchase an entirely new dehumidifier.

If your device is placed in a damp environment , or is running constantly, you can ease the load on the switch for overflow by purchasing a humidifier with a large capacity, like this 50-pint unit by HomeLabs.

13. Blocked Drainage

The blocked drainage hoses aren’t only drainage obstructions that could cause leaks within your dehumidifier. If the drain your hose flows through is blocked, it may create a water build-up which create the water to accumulate in the dehumidifier.

Dehumidifiers that drain gravity require negative pressure in order to move water out of the unit out into the drain. If the hose’s end is sitting in water that is stagnant and it is causing pressure over the system, stopping the water from flowing out.

The solution is usually as easy simply as raising the hose to ensure that the end doesn’t remain in stagnant water. However, if the drain is blocked and causes standing water, you’ll need to call an expert plumber to clean of the drainage before you are able to fix the leak inside your dehumidifier.
