Sub Zero Refrigerator dispenser leaking water
If your Sub-Zero is leaking at the dispenser, start with the dispenser door — a broken or misaligned door often lets water run out or fail to close after dispensing, and you may need to remove the control panel or trim to inspect it. Next check house water pressure; the inlet valve needs about 20 psi to operate correctly, and low pressure or a kinked supply can cause the dispenser to drip. A damaged dispenser actuator or a faulty dispenser switch can fail to open and close the valve properly, so test switches and the actuator for damage or loss of continuity. Finally, the refrigerator water inlet valve itself can be clogged or have bad solenoids; use a multimeter to check for continuity and replace the valve if it fails. Whether you see the refrigerator dispenser leaking water on the floor or the fridge water dispenser not working, these steps cover the usual suspects.

01 - Sub Zero Refrigerator Dispenser Door
The dispenser door is opened by a motor or a solenoid to dispense the ice, but if the door is broken, it may not open properly in order to release the ice. You should inspect the dispenser door for damage to determine if the component should be replaced. You may have to remove the dispenser control panel or frame to access and inspect the dispenser door.

Highly Likely
02 - Low Water Pressure from House Supply
The water inlet valve, which supplies water to the refrigerator water dispenser, requires sufficient water pressure to work properly. If the water pressure is too low, the dispenser will leak. You can check the water flow at the kitchen faucet to help determine if the home's water pressure is sufficient or not.
Common
03 - Sub Zero Refrigerator Dispenser Actuator
The dispenser actuator is the component that activates the switch or switches to send voltage to the dispenser. If the dispenser actuator is damaged, it may be unable to activate the switch. Inspect the dispenser actuator for any damage and replace with a new one if necessary.
Common
04 - Sub Zero Refrigerator Water Inlet Valve
A refrigerator water inlet valve will direct water to the dispenser as well as the ice maker fill tube. If the inlet valve is obstructed, the solenoid coils on the valve are defective, or the home's water pressure is too low, the water valve will not work properly. The valve requires at least 20psi to function properly. Make sure that the water pressure to the valve is at least 20 psi. If the water pressure is sufficient, use a multimeter to test the water inlet valve for continuity. If the water inlet valve does not have continuity, replace it.
Less Common
05 - Sub Zero Refrigerator Dispenser Switch
The dispenser switches send voltage to the dispenser. If one of the dispenser switches is defective, the dispenser will not work. To determine if a dispenser switch is defective, use a multimeter to test each switch for continuity. If a dispenser switch does not have continuity, replace it.
