Installing a dishwasher is a moderately easy job that can be done in one afternoon without the need to hire a professional plumber or electrician. Installing a dishwasher requires 10 steps, according to ThisOldHouse.com.
In order to install a dishwasher without hiring a plumber, first disconnect energy supply from the breaker and close the hot-water valve under the sink. Next, align the water and electrical lines. Hook up the water and electrical supply accordingly and attach the drain line. Attach the dishwasher to the underside of the cabinet and check for leaks. For best results, consult the dishwasher's installation manual for more information and troubleshooting.
