De'Longhi dehumidifier's continuous drain function does not work; water still fills the tank instead of draining through the hose.

Safety first: Unplug the unit before adjusting hoses.

Step-by-step:

• 1. Verify drain setup: Remove the water tank and locate the continuous drain outlet. Ensure any internal drain plug or cap has been removed per the manual.
• 2. Attach hose correctly: Push the drain hose firmly onto the outlet until fully seated. Use a clamp if provided.
• 3. Ensure downward slope: Route the hose so it slopes continuously downward to the drain point. Avoid loops, kinks, or running the hose uphill.
• 4. Check for blockages: Detach the hose and blow through it to confirm it is clear. Also inspect the outlet spout for debris.
• 5. Test operation: Reinstall the tank (if required by design), run the unit, and confirm water flows through the hose instead of filling the tank.
