Anyone who hates washing dishes by hand cannot live without a dishwasher. This appliance handles the undesirable chore in an efficient manner. There is no need to pay a professional to replace a broken dishwasher or install a new one. This project is easy for anyone with basic mechanical skills to do and self-installation saves a lot of money.
You will need:
Step 1: Unplug an existing dishwasher and turn off the power to the area at the relevant circuit breaker. Find the water supply valve for the dishwasher and turn it off. This valve is usually located under the sink. If you cannot find it, turn off the household main water supply, then open one or more faucets to drain the water pipes.
Step 2: If there is no dedicated shutoff valve for the dishwasher, install one. After shutting off the household main water supply, disconnect your dishwasher water supply tube that runs from this valve to the sink. Drain the water from this tube into the bucket. Unscrew this valve from its supply nipple, using the adjustable wrench. Wind pipe wrap tape around the nipple threads and screw on a dual-outlet valve to the supply nipple.
Step 3: Install a dishwasher air gap into a hole atop the sink that is an adequate size. Use slip-joint pliers and a locknut to attach this air gap. Push the cover for the air gap into the proper place.
Step 4: Place the dishwasher near its opening under the kitchen counter. Move to the back corner of your kitchen cabinet under the sink. Drill holes to feed through the supply tube, hose, and power cord. Push each of these through the holes.
Step 5: Walk your new dishwasher into its place, being careful not to pinch or tangle the hose, tube, and cord.
Step 6: Reconnect the supply tube for the sink to the dual-outlet valve. Connect the supply tube for the dishwasher to the other outlet on this valve. The other end should be connected to the dishwasher inlet. Tighten all connections with the wrench.
Step 7: Local the shorter drain hose running from your garbage disposal to the air gap outlet. Slip one hose clamp onto each end of this hose. Use the pliers to cinch the clamps tight. Repeat this process for your longer drain hose, installing one clamp on the air gap outlet and another on the dishwasher base drain fitting.
Step 8: Adjust each of the front feet on the dishwasher until the appliance is level. Align the unit with the cabinets and countertop. Screw in the dishwasher under the counter, following the manufacturer installation directions.
Step 9: Turn on your household main water supply and inspect the dishwasher hoses for leaks. Resolve any leaks and then plug in the dishwasher.
