I am buying LG appliances from many years. Recently I bought a new LG refrigerator. It started to discard white powder from the water dispenser immediately after the delivery. It is not scale, like LG is trying to convince me to think. It is a white powder. This is my third LG refrigerator and I have never had this problem before, and the water is the same.
LG has doesn't want to send a technician to check and fix the problem.
