1. Check if the indoor unit filter is excessively dirty. A dirty filter can restrict airflow, leading to moisture buildup and causing leakage. Clean the indoor unit filter;
2. Observe if water droplets occasionally form at the air outlet. This can be due to high humidity in the air, where water vapor condenses when it comes into contact with cold surfaces. This is a normal phenomenon. You can try closing the doors and windows, raising the temperature setting, increasing the fan speed, or turning on the swing mode;
3. If there is a large amount of water leakage from the indoor unit, immediately turn off the air conditioner, disconnect the power, wipe up the water, and contact the after-sales service for inspection. Ensure that the air conditioner is not used before the service personnel arrive.

19. Q: How to handle water leakage from the outdoor unit of the Mijia Air Conditioner Pro Eco 2.6 kW?
A: The Mijia Air Conditioner Pro Eco 2.6 kW’s outdoor unit does not generate condensate in cooling mode. If water leakage occurs from the outdoor unit during cooling, it is due to the outdoor unit's pipes being at a low temperature during cooling. When the outdoor air humidity is high, condensation forms on the surface of the cold pipes. The condensate then drips onto the base and is drained out through the drainage hole. This is a normal phenomenon and does not require repair.
During heating mode, the outdoor unit can frost over, and the defrosting process can generate condensate. This is also a normal occurrence. If you believe this situation needs to be addressed, you can request an after-sales service to install a drainage nozzle and pipe on the outdoor unit’s base.
Note:
It can also be residual rainwater draining out from the drainage hole after rainfall.
