3. Setup and Installation
Proper setup ensures optimal performance and longevity of your dehumidifier.
Initial Placement:
- Place the dehumidifier on a flat, stable surface.
- Allow at least 8 inches (20 cm) of space around the unit for proper air circulation.
- As mentioned in safety notes, allow the unit to stand upright for 24 hours before plugging it in for the first time.
Drainage Options:
Your Wellsle dehumidifier offers two methods for water removal:
- Manual Drainage (Water Tank):
The unit comes with a 0.66-gallon (2.51L) removable water tank. When the tank is full, the unit will automatically shut off and an indicator light will illuminate. Carefully remove the tank, empty the collected water, and reinsert it securely. In high humidity environments, frequent emptying may be required.
- Continuous Drainage (Drain Hose):
For continuous operation without needing to empty the tank, attach the included 6.56-foot drain hose to the continuous drainage port on the back of the unit. Route the hose downwards to a suitable drain (e.g., floor drain, large bucket) ensuring there are no kinks or blockages in the hose to allow for gravity drainage.

5. Maintenance
Regular maintenance ensures the efficiency and extends the lifespan of your dehumidifier.
Cleaning the Air Filter:
The air filter should be cleaned regularly (e.g., every two weeks or more often depending on usage and air quality) to prevent dust and dirt buildup, which can reduce efficiency.
- Turn off the dehumidifier and unplug it from the power outlet.
- Locate the filter panel (usually on the back or side of the unit).
- Gently remove the filter.
- Wash the filter with warm, soapy water. Rinse thoroughly and allow it to air dry completely before reinserting. Do not use a dishwasher or harsh chemicals.
- Once dry, carefully place the filter back into its slot.

Emptying the Water Tank:
If you are not using the continuous drainage option, the water tank will need to be emptied when full. The unit will stop operating and indicate a full tank.
- Carefully pull out the water tank from the front of the unit.
- Pour out the collected water.
- Slide the empty tank back into the unit until it clicks securely into place. The unit will resume operation.
Storage:
If storing the unit for an extended period, ensure the water tank is empty and clean, and the filter is clean and dry. Store the unit upright in a cool, dry place.
6. Troubleshooting
Before contacting customer support, please refer to the following common issues and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Dehumidifier does not turn on. | No power, power cord not plugged in, full water tank, or temperature too low. | Check power connection. Empty water tank. Ensure room temperature is within operating range (typically above 41°F / 5°C). |
| Unit is running but not collecting water or dehumidifying effectively. | Air filter clogged, humidity setting too high, room size too large, or unit not upright for 24 hours before first use. | Clean the air filter. Lower the target humidity setting. Ensure the unit is suitable for the room size. If this is the first use, ensure it stood upright for 24 hours. If the issue persists, contact support. |
| Unit is noisy. | Unit not on a level surface, or internal components vibrating. | Place the unit on a flat, stable surface. Check for any loose parts. If noise is excessive, contact support. |
| Water leaks from the unit. | Water tank not properly inserted, or continuous drain hose is kinked/blocked. | Ensure the water tank is securely in place. Check the continuous drain hose for kinks or blockages and ensure it is sloped downwards. |
