How can I differeniate between low water pressure or a faulty water valve as the culprit of my leaking (at least a cup per day) in-door water dispenser on my side by side? If it is the water valve how do I replace it?

Jeff has a good troubleshooting link for these here:

I looked through all those before posting my question. I think it is unlikely to be low water pressure. I took the dispenser apart (as far as I could) including trim ring, button pad and "motehrboard" after that doesn't look like any easy way to get to the internals. Where would the water valve be on a PSS25ngna?

P.S. Repair Clinic said to contact a qualified repair technician.

Yes,

Calling a local appliance repair company in your area is always the best thing to do, when your still in doubt, and it becomes more an extreme technical issue that would be almost impossible to solve online.
