GE Monogram Ref - water leaking when disp water

When dispensing water there is water leaking inside at the top of the refrigerator side and on the floor. This only happens when dispensing drinking water. I can see the water valve in the top compartment and it looks okay and dry in that area. The water is leaking in an unexposed area.

Any tips or ideas? Is there a water tubing diagram available?

Thanks.
