This Old House, About.com and the DIY Network all have online videos showing the best way to install a dishwasher. Having the step-by-step instructions is helpful too, but watching a video before starting the process helps the do-it-yourself homeowner visualize the steps that he has read.
The necessary tools for dishwasher installation include a screwdriver, tape measure and crescent wrench. All of the videos emphasize the importance of turning off power to the circuit and the water supply valve that go to the dishwasher. The About.com video is followed by a transcript, allowing the homeowner to read along during the video and then keep the instructions with him during the process.
