DIY Dishwasher Installation Made Easy

Updated: Jun 15, 2020


I purchased this Bosch Silence Plus Brand Dishwasher from Lowe's and trucked it back to the installation location. I used a dolly to cart it into the house. If you have two people you can move it without a dolly. I bought a new voltage sensor, some zip ties, teflon tape, wire nuts, electrical tape, wire strippers, a new hose and threaded brass elbow connector. Some models already come with this and you may possibly be ablate re-use the existing one. Once I got it the house and unpackaged I made sure to turn off the power at the breaker. I verified that the power was off with my voltage indicator so as not to get shocked. I then removed the old dishwasher. I then ran the new steel braided hose through the cupboard hole to the water connection and hooked it up. Then I hooked up the drain hose from the back of the dishwasher to the sink drain. I then adjusted the dishwasher legs to it fit level and flush. I pulled the existing wiring up to the and through the electrical connection box on the dishwasher. I then wired it up to the electrical box. Ended up not needing the wire nuts or electrical tape. I've installed these before where the existing house power cable was not long enough so I'd have to add a splice to make up the distance to the electrical box on the dishwasher. Once everything was tight I turned on the water to check for leaks. I made sure there was not even the tiniest drop of water came out. The connections have to be completely tight. After verifying electrical and water connections were satisfactory I slide the dishwasher into place and secured it to the surrounding cupboards with screws so it didn't move when opening and closing the door. https://www.diy-technician.com https://the-avant-garden.blogspot.com



Once you have removed your old dishwasher you can follow my installation video titled: DIY Bosch Dishwasher Installation: How to Install a Dishwasher in your Kitchen. After unboxing your dishwasher and removing the associated parts be sure to ensure that the power is still off at both the breaker as well as verifying with your voltage checker that it is for sure off. In this installation I first removed all the parts from the inside of the dishwasher. I then played the dishwasher gently on it's side and installed teflon tape around the connection on the dishwasher that would be the mating surface between the brass elbow for the incoming water and the dishwasher itself. After placing teflon tape on there I installed the brass elbow. I then ran the drain hose from the dishwasher to the drain line under the sink and then made sure it was secured to the dishwasher via the provided hose clamp. I then pulled the electrical wiring out and got it ready to hook up. I then hooked up the incoming water supply line to the brass elbow. I then tested it for leaks. Now it was time to do the wiring which was very simple. I made sure I followed the manufacturers recommendations but even without that, the green screw always indicates the ground and then of course you have a 50/50 shot after that for white and black. In this case they show black on the left and white on the right so this is what I did. After hooking up the wiring and making sure it was wired in tight I placed the front cover back on the wiring panel. After that I installed the plastic kick plate along the bottom. I then leveled it and adjusted the height to to match the surrounding cupboards as well as ensure it was level. Then I secured to the surround cupboards using the metal tabs so it would fall forward when the door was opened. Then I turned on the breaker and did some dishes.


Dishwasher Removal

This extraction was a Bosch brand dishwasher. Another Bosch bites the dust. The first thing I didn't was shut off the power at the breaker and verified power was killed using voltage tester followed by unscrewing the drywall screws that were securing the existing dishwasher to the surrounding cupboards including removing the metal securing clips. Then I removed the bottom kickplate. I pulled the dishwasher out a little then turned off the water supply. I then removed the electrical panel cover and unhooked the incoming wiring. I then it was time to unhook the incoming water supply hose using an open ended wrench turning in the normal "lefty loosey" direction for loosening. I then loosened the hose clamps and removed the drain hose. Once everything was unhooked I grabbed the dolly and hauled it out to the truck. There was a local appliance recycling center where I dropped it off for free.



This Samsung dishwasher took a dive. This one only lasted a few years. If you buy this model you can rest assured that you will get good at replacing dishwashers. As always, the very first thing I did was turn off the power at the breaker panel. Then I secured the water at the valve. Many times these are located under the kitchen sink. Then I removed the drain line and kick plate. Had to remove the kick plate to access the electrical box. Now I removed the cover of electrical box with a Philips head used in my cordless drill. Before touching any of the wires I reconfirmed the power was off by testing it using a voltage tester. Confirmed no juice to the wires and removed the wire nuts and pulled wires apart. For the next step I disconnected the incoming water supply hose with an open ended wrench turning it counter clockwise. It may be a good idea to hang onto the brass elbow that the incoming water supply hooks into rather than dispose of it with the dishwasher. These are fairly standard so if by chance you need a spare or if you forgot to buy one with your new dishwasher this can be used as long as the threads still look good. There are many times when they can't be re-used as well b/c they are so old. I now removed the dishwasher, hauled it to the truck with a dolly and took it down to the local appliance recycle center where they took it for free.
