The comments above really helped.  I used a butter knife to open the panel.  Once you have it open.  You have to disconnect the wires and it is a bit of a pain to get the dispenser out.  I had to use the butter knife again to unhook it from the metal piece.

Thank you to all the above for the help.  Took me 20 mins.
