Donnie,

You need to first, unplug the power cord at the outlet, so you don't hurt yourself, or the machine.

On the bottom edge of the dispenser front panel, you'll see two slots formed in the plastic panel, with a flat blade screwdriver, and a pad on the freezer door panel(so you damage the paint) twist the driver or pull out on the slots, until theres enough clearance to slide the whole panel up and the tabs holding it to the freezer door panel come loose and you can remove the panel.

The bracket assembly is held in place with two screws, remove the screws and you should be able to wiggle the complete assembly out and remove the water dispenser fill tube.

Take your time and switch each component, one at a time, and you'll be fine.
