Removing a built-in dishwasher may be required for maintenance.
Portable dishwasher models roll on wheels. You must plug these types of units into an electric outlet, and attach the water supply and drain hoses to the kitchen sink. A built-in dishwasher is contained under the kitchen counter and out of the way. Removing a built-in unit for repair or replacement is involved and should take approximately two hours.
Power and Water Supply
Turn the circuit breaker off on the electrical circuit that the dishwasher is connected to at the main breaker panel. Open the under-sink cabinet next to where the dishwasher is installed and locate the water shut-off valve. Turn the valve in a clockwise direction to shut the water supply to the dishwasher off. Loosen and remove the dishwasher water supply line from the valve with an adjustable wrench. Locate the dishwasher drain hose that will be connected to either the drain under the sink or to the garbage disposal on the underside of the sink. Loosen the screw on the clamp with a Phillips screwdriver and pull the drain hose straight off of the drain or disposal.
Remove Retaining Fasteners
Open the dishwasher door and locate the screw caps that cover the retaining screws that attach the dishwasher to the surrounding cabinetry. Pry the screw caps off with a flat-blade screwdriver and remove the screws with a Phillips screwdriver. Remove the retaining screws that attached the top front edge of the dishwasher to the underside of the counter top with a Phillips screwdriver.
Retract Legs
Close the dishwasher door. Pull the trim cover under the door straight off to reveal the legs. Lower the front of the dishwasher by turning the leveling screws on each front leg in a counterclockwise direction with a Phillips screwdriver. This will reduce the height of the dishwasher slightly and enable you to remove it more easily.
Remove Dishwasher
Open the dishwasher door again. Grasp the sides of the dishwasher and partially slide it straight out from under the counter top. Fish the water supply line and the drain hose from the access hole in the side of the cabinet so that they do not get caught. Reach behind the dishwasher and place the tip of a no-touch electrical tester near where the wiring from the dishwasher is attached to the wiring from the electrical box to ensure the correct breaker was turned off. If the no-touch electrical tester beeps when placed near the wire connections, the correct circuit breaker may not have been turned off. Do not disconnect the wiring until there is no current detected in the wires. Twist off the wire nuts on the wire connections. Untwist the bare wire connections with pliers. Pull the dishwasher completely out from under the counter top.
