Was the glass held under the dispenser long enough?
A few drops of water will dispense after releasing the dispenser lever, this is normal. Hold the glass under the dispenser for 2 to 3 seconds after the dispenser lever has been released.
Was the water filter recently installed? Was the water system flushed?
Flushing the system is needed every time the filter is changed or once the refrigerator is installed to the water supply line for the first time. Flushing the water systems helps to eliminate any debris in the water line.
