Kenmore Side By Side - Door Water Dispenser Leaks

The icemaker works but the water drips from the outside water dispenser. I have the manual but can’t seem to get to the inside of the dispenser to see if it needs a washer or something. So we buy our ice and have shut off the water. Not convenient. How do I get inside to either fix the leak or put a stopper in so that the water can no longer be dispensed?
