Switch off the AC before checking to avoid any electrical risk.
Wipe the water below the AC so you can clearly see if new water starts leaking again.
Open the front cover and inspect the air filter. If it is dusty, airflow becomes weak and water may start dripping.
Remove the filter, wash it with normal water, let it dry fully, and place it back properly.
Turn the AC back on and watch it for 10 to 15 minutes. If water still drips, the drain line may need technician cleaning.
Clean the AC filter every month to prevent water leakage and weak airflow.
