The WATER FULL indicator is designed to advise that the moisture/humidity collection tank is full. When the tank is being emptied, the device should be unplugged. This will allow the indicator to reset. Once the drain process is complete, reconnect the power and set the unit into operation once more. If this is not the case, then the air conditioner will likely require service. To make service arrangements, you may either contact our Customer Interactive Center at 800-243-0000, or you can check our Repair Provider Lookup on our website, at http://www.lg.com/us/support/repair/support-repair-provider-lookup.jsp.
