Water leaking from the indoor unit onto the wall or floor during cooling

Safety first: Turn off power at the breaker before working near the indoor unit. Water and electricity are a dangerous combination.

• Check filters and airflow: Clean filters to reduce excessive icing that can cause overflow.
• Inspect drain outlet: Locate the drain hose connection at the indoor unit. Ensure the hose is not kinked or elevated above the unit outlet.
• Flush the drain line: From the outdoor end of the drain hose, use a wet/dry vacuum to suck out debris, or gently flush with water if accessible. Do not apply high pressure that could disconnect the hose inside the wall.
• Check unit level: Use a spirit level to ensure the indoor unit is slightly tilted toward the drain side. Adjust mounting if necessary.
• Drain pan cleaning: If accessible, remove the front cover and gently clean the drain pan of slime and dirt using a mild disinfectant.
• Persistent leaks: If leaking continues, a technician may need to access internal drain components or a concealed pump (if fitted).
