Hi all: A couple of weeks ago I powerwashed my patio and accidentally sprayed some water to the outlet where my powerwasher is plugged in, and it stopped immediately. It must be tripped a GFCI, but I can't find it. As a result, 5 outlets are dead (all used to be working), one in backyard, one in front porch, one in restroom of the first floor, one in hallway to garage (where washer/dryer are), and one in garage. I have been crazily looking for this hidden GFCI, but no luck so far. I read many internet posts related to this problem. Logically, the "hidden" GFCI should either be in first floor restroom or in garage. I moved everything in garage, and also looked at the heater room. I also mapped all the breakers to the lights and outlets in the house. Unfortunately, I couldn't identify three breakers. One of them must be my dead line. This house was built in 1988, and I moved in 10 years ago. This is the first time I got a GFCI tripped. There are three GFCI outlets in house, one in kitchen, one in kids rest room, and one for master rest room. All breakers are simple breakers (no GFCI buttons), and work fine based on multi meter. This old house has weird wiring, e.g. the outlet in the balcony of the master bedroom is connected to the GFCI outlet in kids restroom, instead of master restroom right next to it. Which kind of tool is there to locate a hidden GFCI? If I can't really find the hidden GFCI, is there a way to work around it? Is it possible to rewire one of the outlet and then make all 5 outlets in this circuit work again? Update on Jun. 27, 2016: Thank you all very much for your responses. This is a two-story house. I have a small kitchen (no island) and I only find one GFCI there (must be two?). The outlet that got water-sprayed on is the far-most one from the breaker panel. The closest outlet (that stops working) is in the garage about 40 ft away from the breaker (on opposite site walls of the three car garage). As I found out, everything (except this outlet) around the garage (garage door controller, lights inside and outside of garage and even in attic, even the sprinkle system) are connected by the same breaker. This is the only outlet in garage wall I can find (strange because I really need more). There are a couple outlets on garage roof which provide power for two garage door openers (and I have to get extension from there). There are two breaker boxes. I was puzzled by the inaccurate or wrong labels because I did see "GFI" on panel 2 diagram, but don't know what it means. I'm loading up some photos of it. Anybody can decipher it? I'm also uploading the new map of the breakers based on my effort. Note that there are three breakers I couldn't identify.
