The dehumidifier's water bucket may have issues causing water leakage. Examine the bucket closely for any cracks and make sure it is placed correctly inside the dehumidifier. If your model has a drain hose attachment, inspect where the hose connects to ensure the fitting has a gasket seal that is properly secured. Improper bucket positioning or a damaged, cracked bucket could lead to water spilling out. Checking these potential problem areas of the bucket and hose connection fitting will help identify and resolve the cause of the leaking water.
