I have a similar problem, water and ice light stays on but no water can be dispensed. The ice works but not water.
I have the Samsung Family Hub fridge with the ice/water dispenser and three doors.
For some reason, all of a sudden the water and crushed ice lights are on and stay on and we cannot dispense ice. The ice maker works but no ice will come out. I have reset the fridge (family hub) and the ice maker and the problem persists. I have unplugged the fridge and the problem persists.
Anyone have any remedy for this?
