Why is my dehumidifier leaking water?

There are several reasons why your dehumidifier may be leaking water. Fortunately, there are some very easy checks you can do to test:

1. Check to see if the water bung is in place

In some models there is a bung (water stopper) to cover the water outlet for continuous drainage.  Check that the bung is securely in place. 

2. Test to see if it is the tank itself that is leaking

Remove the water tank from the dehumidifier, fill it with water and let it sit inside a dry sink overnight. Then check if water is leaking from the water tank. 

3. Visual check the water float in the water tank

There is a water float in place at in the water tank.  Visually check that it is not stuck or broken.  The float should be able to move freely up and down to gauge the water level.

4. Test to see if the surface is level

Run the dehumidifier on an area where the surface is flat and level (not on a carpet). Just be mindful you do not place in on a surface that you do not want any leakage to happen. Run it for a couple of days to see if it still leaks.

5. Test to see if water has seeped into crevices

It is advisable to allow at least an hour for condensation to drain into the water container before moving the appliance as there still will be water inside the unit draining toward the water container. Sometimes the dehumidifier can appear to be leaking if the appliance has been moved whilst condensation is still dripping from the condenser. Water and condensation will slowly seep into the crevices inside the appliance when moved. In this case, the water may slowly leak out from the crevices and seem to be a leak rather than a "slow spill".

6. Test continuous drainage is secure

If you are using the continuous drainage, please check your installation. For advice when setting up your continuous drainage hose, check Installation tips for the continuous drainage hose

7. Moving the dehumidifier whilst water tank contains water.

When moving the dehumidifier please ensure the tank is completely empty.  Any water in the tank will spill inside the dehumidifier if you carry the dehumidifier around.  The water will then slowly seep out. 

8. Emptying the tank

When removing the tank from the dehumidifier, do be gentle as water can spill out of the tank. Use both hands to remove it so that the water does not tip out accidentally.  Removing the tank whilst the machine is still running could cause water to drip into the base of the machine. Water will accumulate inside the base of the tank and eventually leak through the joints of the panel. It is advisable to turn the machine off for 30 minutes to allow the water residue to settle before removing the tank. Finally ensure the lid is properly secured to the tank before inserting into the tank.

9. Dust build-up inside the dehumidifier

Cleaning your filter every 2 weeks is a good practice to avoid any accumulation of dust in the interior.  Any dust build-up can cause a leak if the drainage into the tank is blocked by dust. This will eventually lead to overheating and failure.  Be aware that dust build-up is not covered under warranty.  Annual service on your dehumidifier will be recommended to maintain a clean interior.

10. Use in ambient condition within the specification

For compressor dehumidifiers, the operating temperature are between 15C to 35C.  If the dehumidifier is used in temperature range below 16C, the condenser may freeze and the dehumidifier goes into a defrost mode, leading to condensation.  Excessive condensation will overflow from the tray.  This can be exacerbated if the filter has not been regularly cleaned.  We recommend that filters should be cleaned every 2 weeks.
