If you’re installing a new dishwasher, begin by switching off the power at your circuit breaker. Next, unscrew any screws connecting it to countertops or cabinetry before starting to move forward with assembly.
Lay the dishwasher on its back to gain easy access to its power cord, water supply line and drain hose connections. Also make sure that the front access panel has been removed as well as replacing its wire connection housing cover.
Get the Right Parts
Dishwashers are labor-saving appliances that make life in the kitchen simpler, as well as energy and water efficient. When installing one, however, there are some rules you should abide by – such as making sure its power cord is in good condition and that its drainage works efficiently.
Install a shut-off valve on the water supply line as required, then connect a drainage hose from your sink drain or garbage disposal to connect with its drainage syphon.
Before beginning work on your dishwasher, lay a towel or piece of cardboard underneath to protect the flooring and countertops from potential spills or scrapes. Gather together a drill/hole saw, screwdriver, pliers and level; in addition to that prepare shallow pan, bucket and sponge to collect any of the water that may drain from its lines when you disconnect them. However, please be mindful that working with electrical connections is potentially hazardous; for your own safety consider hiring professional help for this step.
Get the Right Tools
To ensure a successful dishwasher installation, it’s essential that you equip yourself with the appropriate tools. This includes purchasing supplies such as stainless steel braided water supply lines and appliance power cords – this will help prevent issues like leaks or overheating in later steps.
Before beginning, it is wise to switch off both electricity and water (at the circuit breaker and valve under your sink, respectively). Next, remove the front access panel on the dishwasher and carefully lay it backward so as to make its electrical wiring and plumbing connections more accessible.
Next, ensure that you have all of the tools needed for splicing tubing and drilling holes. A box cutter or utility knife are ideal for cutting tubing; while a drill equipped with a hole saw is essential to creating holes for plumbing and electrical wires. Heavy-duty pliers may also come in handy when working with thick tubing.
Make Sure Your Countertop Is Level
Make sure that the dishwasher is properly levelled when installing or replacing it for optimal results, helping avoid rattles and leaks as well as increasing efficiency of operation. Doing this will prevent rattles from the components as well as ensure proper performance from your appliance.
Starting by turning off both power and water supply valves under your sink, remove the front access panel to locate the junction box; this should be a square metal box with three exposed wires that you should identify using color code to connect back with your dishwasher’s power cord (white to white, black to black and green to green).
Install the drain line, connecting it to an air gap that prevents dirty sink water from seeping back into the clean dishwasher water, according to your local building codes. Don’t forget a flexible hose that arches over the pipe for extra kink prevention!
Make Sure Your Drain Lines Are Tight
Before beginning installation or replacement of a dishwasher, be sure to switch off both electricity at the circuit breaker and shut off the water supply valve in your cabinet where your new device will reside. Turning back on either power source could potentially cause shorts or fires when connecting components together; make sure these steps are completed successfully prior to making these connections!
Locate your dishwasher’s water inlet, usually located under its cabinet on its underside, which typically features male or female threads depending on your system and plumbing set-up. Secure Teflon tape around these threads in order to create an airtight seal and secure a leak-free connection; screw water line tight onto this inlet until secure with any tightness facing towards the back of the machine.
Next, connect the dishwasher’s drain hose to either your sink tail pipe or garbage disposal inlet. If using a garbage disposal, looping up its drain hose may form an air gap to stop backflow into your sink.
