The disposal also looks like it has been leaking a little...the bottom
of it is wet (not dripping), and when I pushed the reset button (it did
nothing), my finger was wet with about 2 drops of water.

If there is moisture in the reset switch,
it sounds as if there is a seal that has gone.

An electrician probably wont be able to do anything,
as it sounds as if the unit is faulty,
and the breakers are dong their job!

If you don't feel up to taking the thing apart,
then you may be able to get it serviced somewhere...
