Report "4hp disposal. keeps tripping the gfi outlet. the reset button on the disposal itself doesnt seem to be tripped. had some change (dont ask) get in the disposal just before the problem started and completely jammed the unit. needed to use the allen wrench to spin it backwards to get the coins (really.....dont ask) out. could the disposal finally have blown? its about 8 or 9 years old. thanks, mike"
