Frigidaire Dishwasher Not Draining Ft Valley GA

Went on a call today in Ft Valley, Ga about a frigidaire dishwasher that was not draining.  I got there and saw the dishwasher still had water in the bottom, and boy did it stink.  So I go to start a wash cycle to see what’s happening with the drain.  The first thing most dishwashers do when you start a cycle is drain.  So immediately I notice the water backing up in the sink.  It wasn’t the dishwasher that was stopped up, it was the garbage disposal.  I turn the disposal on with the switch and I hear nothing.  I turn the switch back off and look for the reset button on the bottom of the disposal.  It’s normally a red button.  I push the reset and turn the switch back on and it just hums.  NEVER stick your hand in the disposal with the power to it on.  So I turn the switch back off and start digging around inside the disposal.  There was lots of gunk buildup and other debris in the disposal.  I cleaned it out, turned the switch back on, and everything started draining like it should.
