Water dripping from the indoor unit into the room is not normal. Separate it from normal condensate leaving the outdoor end of the drain hose. Drain blockage/slope, the condensate tray, insulation, airflow and icing are the main branches to check.
Quick answer
First identify where the water appears. Dripping from the front or underside of the indoor unit into the room is a fault symptom; water leaving the outdoor end of the drain hose can be normal condensate during cooling or dehumidification.
Likely causes
A blocked drain hose or incorrect slope, tray/connection problems, damaged or insufficient pipe insulation, dirty filters with low airflow, and evaporator icing are common branches to investigate.
Safe checks
Check the filter according to the user manual and inspect only the visible drain hose for a kink or crushing. If water reaches electrical parts, turn the unit off and isolate power safely.
What a technician checks
Drain flow and slope, condensate tray and connections, coil temperature and airflow, sensors, and when needed the operating values of the refrigerant circuit are checked.
When to stop using it
Do not remove covers, bypass safety circuits or work on live parts. Stop use if water reaches electrical components, there is a burning smell, smoke or repeated breaker trips.
Switch off and safely isolate the air conditioner if water reaches electrical parts, there is burning smell/smoke or the breaker repeatedly trips. Do not open the refrigerant circuit or interfere with refrigerant pipes.
