Water tank fills too quickly or overflows even with continuous drain hose attached.

Safety: Turn off and unplug the unit before adjusting the drain hose.

Steps:

• Hose routing: Ensure the hose runs downward from the drain port with no upward loops. The end of the hose must be lower than the drain outlet on the unit.
• Check for clogs: Disconnect the hose and flush it with water to clear any blockage.
• Drain adapter: Verify that the internal drain adapter or plug is correctly installed and sealed to the drain pan.
• Test without hose: Temporarily remove the hose and operate with the tank only. If the tank fills normally without leaks, the issue is with the hose setup.
