Your Kenmore dishwasher installation should take between two and three hours. Start your installation off right by making sure everything is ready. The fresh water and sewer connections should already be installed. Decide whether the unit will be plugged or hard-wired in. Pick up a dishwasher installation kit, which typically contains a fresh water hose and a power cord. Purchase a trim kit if you prefer different trim than what is included with the dishwasher.
Pull out the wires from the electrical connection underneath the dishwasher. Use the wire strippers to strip the ends of the white, black and ground wires on the power cord. Twist the white wire from the power cord together with the white wire from the dishwasher, using an approved wire nut. Repeat this step with the black wire and the ground wire. Skip this step if an electrician is installing the power cord or wiring the unit directly in.
Install the drain hose to the dishwasher drain connection, making sure that the hose is on tight. Use a screwdriver clamp or squeeze clamp for a tight seal. The drain connector is located on the back or underside of a Kenmore dishwasher.
Push the dishwasher underneath the counter. Level the dishwasher and adjust its height by unscrewing the screw feet underneath the dishwasher. Remove the dishwasher from the opening.
Locate the fresh water connection behind the toe-kick cover on the front of the Kenmore dishwasher. Apply the thread seal to the brass fitting that is included with the dishwasher. Install the brass fitting to the fresh water connection on the dishwasher. Screw on the fresh water hose to the brass fitting and tighten well. Install the other end of the fresh water line to the hot water connection underneath the kitchen sink. Turn the water supply on and check for water leaks under the sink, along the hose and under the dishwasher.
Slowly push or roll the dishwasher underneath the counter. Keep an eye on the water line, sewer line and power cord to ensure they are not pinched or damaged. Re-check the level from back to front and side to side, adjusting if necessary.
Position a metal anti-tip tab—included with the Kenmore dishwasher—underneath the counter in front of the dishwasher. Use a screwdriver or cordless drill and a screw to install the tab on the underside of the countertop. Repeat for the second anti-tip tab.
Start the dishwasher and run empty for a complete cycle. Inspect underneath the sink, underneath the dishwasher and along the length of all hoses for any leaking water. Replace the toe-kick cover. Place one screw in the cover and screw it partially down. Repeat with the other three screws. Tighten all four screws down.
