Water dispenser not working, parts replaced

The water dispenser does not work but the ice maker does. I put a new filter on it and today a new water valve on the back. No water came out for me but my wife just tried it and 1 glass of water came through but no more. I assumed it was the switch on the door but she got 1 glass of water out of it. Been trying and no more will come out. Help!

OK, pretty sure its the actual switch in the door. How do I get the plastic front off of the door to get to the switch?
