Water tank does not fill even though the unit appears to be running normally.

Safety first: Unplug the unit before checking hoses.

• Check for drain hose: If a hose is connected, water will not collect in the tank. Verify that the hose is properly routed to a drain.
• Inspect internal connections: Open the unit and ensure the internal drain outlet is correctly connected to either the tank or hose adapter.
• Examine tank: Remove and fill the tank with water over a sink to check for leaks or cracks. Replace if leaking.
