How to Make Electrical Connections on a Dishwasher
Handy-man Hans Vatter demonstrates how to make electrical connections.
Hans Vatter: Hi, I am Hans Vatter and we are installing a dishwasher today. In this clip, we are going to be removing the access panels and making electrical connections. We are going to remove the new access plate. This one in this particular dishwasher is a solid piece. Instead of having two separate ones we just have one and it has two screws, one on each corner. Now that we have the cover removed we can see that electrical box is located and it's little hard to get to but with a long Phillips screwdriver you can get to it. We are going to remove the screw and that will give us access to the wire. We will take these wire nuts and we will take the wire nuts off. We have already tested and established that the circuit is dead so we don't have to worry about getting shocked at this point. We are going to remove the locknut that comes on the connector. You have got to remember that this is backwards we are going to be putting the wire through the backside of the box so that the threads to that connector are going to be towards you as you are looking at it . We will slip those over the wire, we will pull the wire out enough to where we can work on, we will take our screwdriver and we will tighten this wire connected to that. Now, the idea when you are tightening these up is you want to make sure that the wire can't pull out of the connector so you can look here and you can see how it's tight on to the wire.
Now we will go ahead and strip the wires. You will need to strip about two-eighths of an inch off of the wire. Now we are ready to put that wire through the back of the electrical box and it's just a matter of fishing it through the hole provided until the threads at your -- the connector is showing through the other end. We are going to take the locknut that came with the connector, we are going to slide it over the end of the other wires and we are going to tighten it on to the fence.
Now we are going to take a regular screwdriver and we are going to use it to turn the nut. All you have to do is just push out and when you are using this method you got to make sure that you don't slip off and cut yourself on something sharp down there. So you just want to just take the end of your screwdriver and move the nut until it's snug and it is snug enough there. Now we are going to take the ground wire which is the bare copper wire and it has to go the ground terminal on the dishwasher. Now it is usually indicated by a green screw and we will take a screwdriver and we will make sure that the green screw is unscrewed enough to allow for the wire to go onto it.
We are going to bend a little loop into the copper wire so that when you place the copper wire over it, you have something that it will hold onto. Once you have put the loop over the copper, we are going to tighten that screw right back up. Now this ground wire that we are installing, that's an important safety factor, in case your dishwasher has an electrical short it will go to ground instead of you unless you touch the dishwasher you could be electrocuted. This is safety feature that is very important, so don't skip putting this green wire to the bare copper wire. Once you have that done, if you have noticed that you have a black wire and white wire and you also have a black wire and a white wire on the dishwasher. Now what we are going to do is take a wire nut, in this case, we are going to use an orange wire nut and we are going to take the white wire and we are going to twist it up. Okay, now we will do the black one. Okay, you tighten these wire nuts up until you feel like the wires are secure and then not go pulled off when you tug on that wire nut. All the excess wire, I am going to twist up inside of this box and now we will put the cover back on.
Coming up next, we would demonstrate how to connect the water line.
