Condensation created during cooling should leave safely through the drain line. Water from the indoor unit commonly indicates a drainage problem.
Possible causes
- A blocked or kinked drain hose
- Incorrect slope of the indoor unit or drain
- Reduced airflow caused by dirty filters
- A problem with the drain tray or connection
- High humidity and insufficient insulation
What should you do first?
Switch the unit off, protect items below and make sure water is not reaching an electrical socket. Pressurised air or chemicals can damage some components if used incorrectly.
Useful service details
Provide the make and model, where water appears, how long it takes to start and a photograph of the external drain outlet.
