Dishwasher wires twice Oct 26, 2019 I removed my old dishwasher and found that it was wired to the wall and another wire ran behind a plug box under the sink. Why would there be two wires? And do I need to hook the new dishwasher up to both places? #Dishwasher #Wiringhttps://diy.stackexchange.com/questions/166830/dishwasher-wires-twice Tags: Dishwasher Wiring Share Share on Facebook Tweet Tweet on Twitter Pin it Pin on Pinterest
