When ice is dispensed, especially crushed ice, the refrigerator may experience residual ice in the ice chute. When the residual ice melts, it appears as if it were a leak from the water dispenser. To avoid this, keep the ice chute free of residual ice. Dispensing some cubed ice after getting crushed ice will help clear out the chute as well.
If the ice chute is free of residual ice, but a steady stream of water continues to dispense along with the ice, please contact a Samsung service centre.
