A dishwasher is a modern convenience considered a necessity by people who hate to do dishes. When building a new home, remodeling, or replacing a broken model, installing a dishwasher is something you can do yourself. Follow these tips to install a new dishwasher and avoid having to wash dirty dishes for the rest of your life.
You will need:
Step 1: Remove an existing dishwasher by unplugging it and turning off power to the appliance at the circuit breaker. Locate the dishwasher water supply valve, which is usually under the sink, and shut this off. If you are unable to find this valve, turn off the main water supply to the home and drain the pipes by opening a faucet.
Step 2: if the dishwasher does not have its own shutoff valve, install one. Shut off the main water supply valve to the house. Disconnect the water supply tube to the sink from this valve and drain the tube into a bucket. Use the wrench to unscrew the valve from the supply nipple. Wind some pipe-wrap tape around the threads on the nipple, and then screw the dual-outlet valve onto the nipple.
Step 3: Install the air gap for the dishwasher into an adequately sized hole in the top of the sink. Use the slip-joint pliers to secure the air gap with a locknut at the top. Push the air gap cover into place.
Step 4: Position the dishwasher near the opening under the counter. Drill holes in the back corner of the cabinet for the sink base to feed the power cord, supply tube, and hose through. Push these items through the holes.
Step 5: Walk the new dishwasher into place, taking care not to tangle or pinch the tube, cord, and hose.
Step 6: Reconnect the sink supply tube to the newly installed dual-outlet valve. Connect the flexible dishwasher supply tube to the second outlet on the valve. Connect the other end of the tube to the inlet on the dishwasher. Use the wrench to tighten both connections.
Step 7: Slip a hose clamp onto both ends of the short drain hose that runs from a garbage disposal to the large outlet on the new air gap. Cinch these clamps with the pliers so they are tight. Follow the same process for the long drain hose, installing one end on the small air gap outlet and the other on the drain fitting located at the dishwasher base.
Step 8: Adjust the front feet of the dishwasher to level. Align the dishwasher with the countertop and cabinets. Screw the dishwasher in underneath the counter according to the product instructions.
Step 9: Turn on the main water supply and check for any leaks. If none are found, plug in the new dishwasher.
