[LG Water Purifier] How to use the Internal Sterilization feature

Repair

The Internal Pipe Sterilization feature ensures the hygienic management of the internal water passage by eliminating 99.99% of adherent and suspended bacteria inside the pipes.
This feature operates automatically on a weekly basis.
Initially, the sterilization process takes approximately 15 minutes.
However, starting from the fourth week, the duration extends to 30 minutes.

Try this

Long press the Internal Sterilize button for 3 seconds.
Manual sterilization will last for about 30 minutes, and during that time, other functions are unavailable.

1. If you would like to cancel Internal Sterilization while it is in progress, press the Internal Sterilize button for at least 3 seconds.
If you cancel Internal Sterilization, internal cleaning will take place for about 5 minutes, so please wait a moment.
※ Details of the cleaning process after cancelling Internal Pipe Sterilization.
Internal cleaning lasts until the cold water tank sensor detects a temperature below 35℃ and the temperature difference between the feed water sensor and the water outlet sensor is within 5℃.
As cleaning duration depends on the internal temperatures of the product, there may be a variation of 1 to 5 minutes in cleaning times.
2. Upon completion of Internal Sterilization, the cold water may not reach its optimal chill for up to two hours.
During Internal Sterilization, hot water passes through the stainless steel pipes inside the cold water tank.
The temperature of the coolant inside the cold water tank rises due to this heat, resulting in cold water not being chilled enough momentarily.
3. Internal Sterilization runs automatically once every 7 days following product installation.
And once every 4 weeks, the stainless steel pipes inside the cold water tank are also sterilized.

If you would like additional sterilization, you can initiate a manual sterilization process by pressing the Internal Sterilize button.
This manual process also includes the sterilization of the stainless steel pipes inside the cold water tank.
