Dehumidifier Leaking Water

If your dehumidifier is leaking water, the problem could be caused by a full or improperly installed water bucket, a clogged drain hose, a cracked water tank, or a blocked drain system. Before replacing any parts, inspect the most common causes listed below.

Safety Notice: Always unplug the dehumidifier before servicing it. Clean up any standing water immediately to reduce the risk of electrical shock or damage to flooring.

Possible Causes

  • Water bucket not installed correctly
  • Cracked or damaged water bucket
  • Clogged drain hose
  • Blocked drain opening
  • Dirty evaporator coils
  • Unit is not level
  • Damaged drain pan
  • Frozen evaporator coils

1. Water Bucket Not Installed Correctly

Most Common Solution

If the water bucket is not fully seated, water may leak around the bucket instead of draining into it properly.

What to do:

  • Turn off and unplug the dehumidifier.
  • Remove the water bucket.
  • Reinstall it securely until it is fully seated.
  • Restart the unit and check for leaks.

2. Water Bucket

A cracked or damaged water bucket can allow water to leak onto the floor during operation.

What to do:

  • Remove the bucket and inspect it for cracks or damage.
  • Fill it with water to check for leaks.
  • Replace the bucket if it is damaged.

3. Drain Hose

If your dehumidifier uses a continuous drain hose, a clog or loose connection can cause water to leak.

What to do:

  • Disconnect and inspect the drain hose.
  • Remove any clogs or debris.
  • Ensure the hose is securely connected.
  • Verify the hose slopes downward without kinks.

4. Drain Opening

The drain opening can become clogged with dirt, mold, or mineral deposits, preventing water from draining properly.

What to do:

  • Disconnect power.
  • Inspect the drain opening for obstructions.
  • Carefully clear any debris.
  • Flush the opening if recommended by the manufacturer.

5. Evaporator Coils

Dirty evaporator coils can interfere with normal condensation and drainage, allowing water to collect where it should not.

What to do:

  • Unplug the dehumidifier.
  • Inspect the evaporator coils.
  • Clean the coils using a soft brush or vacuum.
  • Restart the unit after cleaning.

6. Unit Is Not Level

If the dehumidifier is placed on an uneven surface, water may not flow correctly into the bucket or drain system.

What to do:

  • Place the dehumidifier on a flat, level surface.
  • Adjust its position if necessary.
  • Verify the bucket is properly aligned.

7. Drain Pan

A cracked or damaged drain pan can allow collected water to leak before reaching the bucket or drain hose.

What to do:

  • Inspect the drain pan for cracks or damage.
  • Clean away any debris.
  • Replace the drain pan if it is damaged.

8. Frozen Evaporator Coils

Ice buildup on the evaporator coils can melt during the defrost cycle, causing excess water to overflow if the drainage system cannot keep up.

What to do:

  • Turn off the dehumidifier and allow the coils to thaw completely.
  • Inspect the air filter and airflow.
  • Check the drain system for clogs before restarting the unit.
