I bought a Bosch 800 Series Dishwasher Model SHP68T55UC to install into my year 2000 house. Whenever I read tutorials online for installing dishwashers, I see that the ground wire goes to a metal plate like so:
However, the instruction manual for my dishwasher never tells me to do that. It tells me to put all 3 wires into a box. The green ground wire never goes to the metal plate.
Here, I've followed the instruction manual. As you can see, I have a 3 pronged plug. The wall outlet under my kitchen sink also has 3 holes. I believe the 3 prongs correspond to the ground, neutral, and hot. Is this setup enough to ground my dishwasher? Why is virtually every other tutorial on the internet telling me to attach the ground wire to a metal plate? Is it because they assume you have a 2 pronged outlet with no grounding?
