Whirlpool Side by Side Refrigerators water dispenser repair?

I have a Whirlpool Side by Side Refrigerators and the water dispenser just stopped working. The ice dispenser an the light are working just fine. Is there any information on how to diagnostic and repair this. I am trying to open up the dispenser, but don’t know how. I read the posting on the “Can I repair the water/ice dispenser in the door of my KitchenAid Superba?” but it seems the fix does not apply to this Whirlpool Refrigerators. Anyone can provide some hints and directions is highly appreciated. Thank you.
The model is ED5FTGXKQ02
