Symptoms
- Water pooling under or around the unit
- Water dripping from the back or bottom
- Leak worsens on humid days
- Unit shuts off with a full-tank indicator lit
Likely causes
- CommonFull internal condensate tankOnce the internal reservoir overflows, water can leak from the base.
- CommonUnit not sitting levelTilting can cause water to spill past the internal tank instead of draining as designed.
- PossibleLoose or missing drain plugA drain plug that isn't seated fully lets water seep out continuously.
- PossibleCondensation forming on the exhaust hose in very humid conditionsMoisture can form on the hose itself and drip down.
What to do
- Unplug the unit and check the drain plug (often on the back or bottom) to make sure it's fully seated and not cracked.
- Look for a full-tank indicator light or drain the internal reservoir manually per the manual's instructions.
- Set the unit on a level, hard floor; use a small level to confirm it isn't tilting.
- If the unit supports continuous drainage, attach a drain hose to the lower port and route it to a floor drain or bucket instead of relying on the internal tank.
- Check the exhaust hose for condensation buildup in very humid rooms and wipe it dry.
- Empty the tank on a regular schedule (daily in humid weather) if the model doesn't self-evaporate all the moisture.

When to call a pro
Call an appliance technician if water leaks even with a level unit, empty tank, and secure drain plug, since that can mean an internal pump or pan issue.
