Replacing a Dishwasher – Part 2

So now we’re continuing on from the first part of this adventure of replacing our dishwasher (part 1 is here).

dishwasher fitting to our supply lineThe next thing we are going to do is we are going to connect our dishwasher fitting to our supply line. Dishwashers come with two different styles of a fitting. One is 3/8ths IPS by 3/8ths compression, the other one is three quarter hose thread by three eights compression. And this is becoming more and more popular – the three quarter hose, in fact this dishwasher takes it and it did not come with it.

So make sure you check the instructions or ask where you purchase your dishwasher, if you need a fitting, because in some cases you are going to have to pick one up. So what I am going to do is I am just going to take this fitting, I am going to use a pair of pliers and a channel lock to hold the fitting and I am just going to snug this down first and then I am going to, actually, a little tip, take a little tape and tape down your supply line, your discharge hose and your electrical supply and then you’ll be able to slide the dishwasher right over the top of all three.

I just pushed the dishwasher back in place and we are going to connect all of the replacement parts (plus a little guidance from the experts at Austin Appliance Masters – http://austinappliancemasters.com). Now we are going to take a level, so we are going to adjust our front legs. And I like these just inexpensive plastic levels with a magnet on it and it just makes it very easy to do jobs like this. So now we’ll just take our feet and we’ll bring it up to its plumb, just like that and then we’ll set the level on the top.

You want to hand tighten this and snug it down and then you are going to use a pliers and do a quarter inch a time until it snugs up. You definitely don’t want to over tighten this and make sure you hand thread it first, so you don’t cross thread it.

Next step, you are going to connect your hose and our just has a push fit fitting, so depending on the manufacturer, it’s going to be a little different. But this one just snaps into our rubber gasket. For this dishwasher, it uses a hose clamp to hold that hose in place and i really like this channel lock hose clamp pliers and you can see this little indentations are designed to snap into this and grab it and hold it in place. So if you want a specialty tool, this channel lock do a nice job for this type of repair.

In the Tucson area we have flexible metal conduit and we don’t have a ground that metal conduit is going to be grounded all the way back.We are going to twist our black wire to the black wire, the white to the white and then put our cover back on. If you are using non metallic cable, you are going to want to make sure you are going to put the ground bare wire to the grounding screw inside the box.

Everything is connected underneath, I am just going to drill a couple of pilot holes and connect these brackets to the bottom of the counter top. The last thing, you’ll just put your access panel on the bottom, you’ll turn on the water and then turn on the electric. And those are the steps to replace a dishwasher.

Replacing a Dishwasher

Replacing a Dishwasher 3We’ll go through the steps on how to replace a dishwasher. So if you have an old existing one, the first thing you want to do is look at the water supply and in this case we have solid copper and I am just going to change that to a flexible stainless steel supply line. It’s going to make it much easier to move back and forth. And take a look at your discharge pipe and the hose, see how it is connected, in case you need any of the parts at the hardware store.

The first thing we are going to do is remove the bottom panel of your old dishwasher and we are going to test it with a tester, just to make sure we have the electric off. I like these non contact testers because you don’t have to open the box and take a chance in touching live wires. So we’ll go down, we’ll turn off the breaker, we’ll find which one operates that and then we’ll go to the next step.

I found the breaker that operates the electric for this and I doubled checked it, there’s no electric on, so I removed the cover to the box on the old dishwasher and it exposes the hot, the black wire and the neutral wire. We are using flexible metal conduit, which is grounded, and highly recommended by the expert appliance guys at www.appliancerepairtucsonaz.org.

So you’re either going to have no ground, if you are using BX like this and it goes all the way back to the service panel and it is grounded or you will have ground wire that’s going to be tied to this metal box. Inside, what I am going to do, there is a nut that holds this strain relief and that flexible metal conduit to this electrical box. So I am just using a regular screwdriver and I am going to hit that nut and unscrew this.

Replacing a Dishwasher 2This will pull our electric away and I am going to use a small pan, put it inside here and using a small adjustable wrench, I shut off the water going to the dishwasher, then I am going to loosen the nut on that supply. So I disconnected the water supply and now I am going to disconnect the hose. Under the dishwasher, I just raised these feet a little bit, if you have a different height in your tile or wood, it’s nice to pull this up a little bit because the next step we’re going to loosen the screws or any brackets that hold the top of the dishwasher in place.

So now on this one, it just has two screws, so we’ll just unscrew them and that will allow us to bring the whole unit out. Once you have the top bracket or screws loose, you can just pull the whole unit out. I have the new supply line connected and I connected it to the valve. What you are going to want to do is take a bucket, open that valve and bleed out in case there is any debris or anything built up and let that run for a few seconds, until it runs clear, shut it back off and then you will be able to connect this to the new dishwasher.

The next thing we want to do is connect the discharge hose to either a garbage disposal, if you have one, or we are connecting it this time to a slip joint with a hose barrel by it. So we are going to connect it to this and then we are going to use a clamp to clamp it in place and make sure you are read your instructions. Different models are different, this one wants to be about 20 inches high with this loop.

So we have a cold cut into the top of the cabinet, which will set it at the correct height. Now that we have the new dishwasher, we pull off the bottom panel, so it exposes everything to us and now they have a chart for the back legs. Before we slide this into the opening, we are going to measure the distance between the floor and the bottom of the counter top and we are going to adjust this.

There’re going to have a few different settings for the back legs. We want to set that first because when we slide it in, we are going to level it by adjusting the front legs. Every dishwasher is going to be a little bit different. This one has a bracket that we are going to insert into a little slot here and then we are going to use a pair of pliers and we are going to bend these tabs up and we are going to lock it in place. This is going to allow us to screw it up into the bottom of the counter top.

This was getting a bit long for a single post, so we’ll continue on with more here in the second half… here.
