I just installed a new Dishwasher in a home bult in 2001. When taking out the old unit and disconecting the wiring i notices a light switch box was installed in the line just before connecting to the Old Washer. Seeing how the Line had it own breaker (it seammed) I removed the switch. When installing the new washer with the breaker off I got a slight shock and Poped the GFCI outlet up above the counter top. Not thinking twice about it i finished hooking up the new Washer (Reminder the light switch was removed) I fliped the breaker and no power. I hit the reset on the GFCI and power is restored to the new Washer!! A couple days pass and I go to make a cup of coffee and there it is the Outlet no longer works. Not the GFCI outlet but 1 of 3 that I beleive are on the GFCI's line. So my first thought was to replace the GFCI outlet as it would not reset or pop if i hit Test. Replaced GFCI and that did not do the trick it still is tripped and will not reset.
I think When I took out the LIght switch under the old Dish washer it did something to the line that I was not aware of. And being and Idiot I threw out the out setup :(. So if I reinstall a switch I am not sure how it was wired. I have one line coming to the dishwasher but I assume up in the wall there is a junction box that I am not seeing that the power splits off of one going to the Disn washer and One heading to the GFCI outline and the 3 outlets after it.
Attached is a picture of the switch before I removed it should have taken one with the cover off also :(. Line on the left is seporate of an outlet on the side of the cabinets.
Thanks in advance for your thoughts.
