[LG Water Purifier Leaks] Dew on the Water Purifier

Causes and Symptoms

It is caused by environmental factors such as large humidity and temperature differences between indoors and outdoors or insufficient air circulation.

In particular, during hot and humid summer months, if there is a significant temperature difference between the installation location and the outdoors, water may condense on the surface of a water purifier with cooling functions, similar to how dew forms on a cold glass of ice.
Therefore, it is important to note that condensation occurring due to temperature differences is a normal and common phenomenon in water purifiers with cooling, and it should not be considered a product defect. The water droplets will naturally evaporate over time or disappear when the temperature difference decreases.

The appearance of water on the insulation surface or any discoloration of the material surface has no impact on the quality of the drinking water.

This is due to the fact that the plumbed-in (tankless) water dispenser is designed with a sealed structure that ensures the water's journey from the inlet, through the water pipes and filter, all the way to the outlet remains completely isolated.

Instant cold water is a cooling method in which water filtered through a filter becomes cold as it passes through cold stainless steel cold water pipes.

Please ensure that that is some clearance between the water purifier and its surroundings.

Insufficient space between the product and the wall can restrict ventilation, leading to the formation of condensation on the surface of the product.
To prevent this, it is recommended to maintain an indoor humidity level of 40~60% and leave a minimum of 10cm of space between the water purifier and the wall.

Maintain an appropriate indoor humidity level of 40~60% and leave a space of at least 10cm between the water purifier and the wall.

If water leaks from the bottom of the water purifier and accumulates on the floor, check if the drip tray has overflowed.

In the case of a water purifier with the cold water function, the difference between the cold temperature of the evaporator, which makes the water cold, and the outside temperature can cause water droplets to form on the surface of the evaporator and drip to the floor.
If the water leakage continues even after wiping the bottom of the water purifier, it is necessary to have it checked by a professional service technician.
After closing the middle water supply valve of the water purifier, please contact customer center.
