■ Solution: How to Drain the Condensate Water
Follow these steps to resolve the issue:
-
Turn off the appliance and disconnect the power cord from the outlet.

Place a large bucket or container under the drainage nozzle located at the bottom of the unit.
-
Open the drainage cap and allow all the water to drain completely.
-
Once the water has fully drained, close the cap securely.
■ Important Safety Precautions
-
Do not tilt the appliance excessively while draining, as this may cause water to overflow.
-
Always empty the water before moving the appliance.
Failure to do so can result in water leakage, leading to electric shock, fire, or property damage.
