What to Check First

Tall apartments or houses at high altitudes may experience low water pressure.
When large amounts of water are used simultaneously in different units of a multifamily residence, the instantaneous water pressure may drop.
Weak flow will be observed in locations where the water pressure is below the minimum water pressure of 1.5 kgf/cm².
This issue is relevant to plumbed-in refrigerators. The UF filter is used.
For plumbed-in refrigerators, the volume of water dispensed depends on the water pressure of the installation environment. Therefore, if the water pressure is low, the dispensed volume will be reduced.
The dispensed volume is 1.4 liters per minute at a water pressure of 4.5kgf/cm². The guaranteed range of water pressure for our appliances is 1.5~8.5 kgf/cm².
Ice left in the ice dispenser’s passageway may melt and drip.
When dispensing cubed ice, use a cup with a wide opening and place the cup near the dispenser to prevent ice from spilling out of the cup.
Only use purified, distilled water to fill up the internal water tank.
Foreign substances may enter the water tank during refills, so please clean the tank and its components once a week.

Why This Can Happen
