In this post, we’ll be answering the question ” why is my dehumidifier leaking water into the floor?”

If you’ve been noticing water on the floor around your Dehumidifier, we’re here to help. 

There are a few different reasons that this could be happening, and we’ll go through each one below.

Why Is My Dehumidifier Leaking Water Onto The Floor?

A dehumidifier is leaking water into the floor because the pump is damaged, a misaligned water bucket, a clogged drainage tube, or a cracked water reservoir. These are the most common reasons.

Below, we go over these and other reasons why a dehumidifier might be leaking water. We will also provide useful repair tips.

What Causes A Dehumidifier To Leak Water?

As mentioned above, there are many reasons why a dehumidifier might be leaking water onto your floor.

We will go over some of the more common reasons below:

The Pump Is Defective

This is among the most common reasons why a dehumidifier is leaking water.

The pump may be defective, which means that the bucket cannot empty properly. The water will continue to build up until the bucket runs out of space.

Another possible reason for a defective pump is if the motor has burnt out, causing it to no longer spin properly.

The Drainage Tube Has Become Clogged

If you notice water on your floor, make sure that there isn’t something obstructing the drainage hose or preventing it from draining into a bucket.

Debris or dirt can easily accumulate in the drainage hose and cause it to clog, resulting in water leakage.

The Water Collection Bucket Is Not Aligned Properly

This issue is often caused by an improperly installed dehumidifier. If the bucket is not lined up with the hole that directs the water into it, the water will overflow and leak onto the floor.

The Water Reservoir Is Cracked

If your Dehumidifier has a water reservoir, it’s possible that this could be the source of the leakage. If the plastic cracks or punctures, the water will flow freely and create a mess on your floor.

Bent Drainage Pipe

This is also a common cause of water leakage. If the drainage pipe is not functioning properly or has become bent, it will prevent proper draining and lead to leaking.

Disconnected Drainage Hose

Sometimes the drainage hose can become disconnected from the Dehumidifier. If this happens, the water will back up into the machine and leak out.

Defective Overflow Switch

This is another common issue that can cause a dehumidifier to leak water. If the overflow switch is defective, it will not turn off the machine when the bucket is full, which will result in continuous leaking.

Frozen Coils

If the coils in your dehumidifier freeze, it can cause water leakage. The ice will melt and release the water, which will flow onto the floor.

How To Repair A Leaking Dehumidifier

If your Dehumidifier is leaking water, the best way to address the issue is by troubleshooting it.

Below are some tips for doing so:

Check the Pump

If you think that the pump might be defective, you can test it by plugging in the Dehumidifier and holding down the power button for an extended time to ensure that it starts up.

If you think it is defective, you can order a replacement pump for your Dehumidifier.

The Drainage Hose

Check the drainage hose and make sure it is connected properly.

If water leakage persists after this step, check to see if there are any obstructions in the tube that prevent proper draining of the machine’s contents.

Once any debris or dirt has been cleared out, try restarting the machine.

The Water Collection Bucket

If the water is overflowing because the bucket is not aligned properly, make sure to realign it and ensure that it is fitted snugly in place. If this does not solve the problem, you might need to purchase a new water collection bucket.

The Water Reservoir

If your Dehumidifier has a water reservoir, it’s possible that the issue is with the reservoir itself. Inspect it for cracks or punctures and replace it if necessary.

The Overflow Switch

You can check if the overflow switch is defective by trying to push it in with a pen or other sharp object.

If it doesn’t move, the switch is probably stuck and will need to be replaced.

The Coils

If your Dehumidifier’s coils have frozen and are leaking water, turn off the unit until it has defrosted completely to prevent further damage to the machine.

If this does not solve the problem for good, consider purchasing a replacement dehumidifier.

If you have tried all of the above steps and your Dehumidifier is still leaking water, it might be time to call in a professional for assistance.

They will be able to properly diagnose the issue and provide a solution.

In some cases, the water leakage is simply due to user error, such as filling the collection bucket too full or not cleaning out the machine regularly.

By following the tips above, you can troubleshoot and fix the issue yourself.

However, if you are still experiencing problems after trying all of these steps, it is best to consult a professional.

Where To Find Dehumidifier Spare Parts

While you can find dehumidifier spare parts in your local hardware store, it is often easier and more convenient to order them online from the official website of the manufacturer.

Ordering from the manufacturer comes with benefits such as warranty protection and fast delivery so you can get back to using your Dehumidifier as soon as possible.

You can also get spare parts from online retailers such as Amazon.

However, be sure to read the reviews before making your purchase to ensure that you are getting a quality product.

Other online retailers such as Walmart and Home Depot also offer a wide selection of dehumidifier spare parts so you can find the perfect part for your machine.
