Indoor unit leaks water from the front or bottom of the casing during cooling operation.

Safety first: Turn off the AC and disconnect power. Place towels or a tray under the unit to catch water.

Steps:

• Check unit level: Use a spirit level to ensure the indoor Blaupunkt unit is slightly tilted toward the drain side as per installation manual.
• Clear drain line: Access the drain outlet on the indoor unit and attach a wet/dry vacuum to the outside end of the drain hose to suck out sludge and algae.
• Inspect drain connection: Remove the front cover and verify the drain hose is firmly attached to the drain pan spigot and not cracked.
• Check for coil icing: If the evaporator is icing up, address airflow issues (dirty filters, low fan speed) or have a technician check refrigerant charge.
