Allow 24 hours for the refrigerator to cool down so that it can chill water properly. Also, the water dispenser needs to have the trapped air in the water line removed when it is first connected or every time the water filter is replaced.
Place a large container below the water dispenser and start pressing and releasing the lever for 5-seconds intervals. Repeat until water begins to flow. Once water starts flowing, continue pressing and releasing the dispenser paddle until a total of 15 litres of water has been dispensed. This will flush the air from the filter and the water dispensing system, ensuring pure and fresh water for drinking.
