1. Is the valve that supplies the water locked or is the water supply valve from the main water line locked?

➔ Check that the water valve or the water supply valve inside the sink is open.

2. Check whether the water supply tube is kinked or bent.

➔ If the hose of the water purifier refrigerator is faulty, or there is a leak in the water connection, lock the water supply valve and request a service call immediately.




3. Remove water filter and test dispenser (temporarily)
4. Check fridge temperature (recommended: 37°F or 3°C)
5. Listen for valve or switch sounds
6. Inspect for frozen lines or ice buildup
