Lg Dehumidifier Not Collecting Water. It could be a dehumidifier not working problem. The dehumidifier may stop collecting water because there simply isn’t enough moisture in the air.
During specific times, the air may stop collecting water since there is not enough moisture in the atmosphere. The humid air condenses on the evaporator coil and the condensate runs down to the catch pan. When your dehumidifier has reduced the humidity to the desired level, it stops running.
