The night light function is activated by "power reset + door control operation", specific steps:

1. Power Reset: Turn off the main power, wait 10 seconds, then restore power.

2. Door Control Operation: Within 60 seconds after power restoration, quickly "open-close" the water intake door (located in front of the water outlet) twice in 3 seconds.

3. Status Switch: After the operation, the night light will switch status (on to off, off to on).

Notes:

- If the operation exceeds 60 seconds or the number of times is insufficient, reset the power and try again;

- The night light is only recommended for use in low-light environments at night to avoid energy waste during the day.
