Mr Rooter’s Tip Of The Day
Installing The Water Lines
Tip #1 In the side of the dishwasher cabinet nearest the sink and in the back just below the countertop, drill a 1½-inch hole for the drain line. Then drill a 1-inch hole in the bottom of the same side for the water line.
Tip #2 Very gently, lay the dishwasher on its back and remove the fasteners (Phillips-head screws or ¼-inch hex head screws) that hold the kick-plate (the plate immediately below the door).
Tip #3 Set the kick-plate aside and do not bend or scratch it. This exposes the area in which the connections for the water and electrical lines may be found; the water line solenoid is on the left and electrical connections are on the right. Make sure the drain hose is already attached to the dishwasher pump; if it is not, attach it with the clamps that came with the washer for this purpose.
Tip #4 Look for the dishwasher solenoid at the bottom left. You’ll recognize the ⅜-inch female thread attached to it. That’s where the water line fitting goes. Hand tighten the water line fitting (a ⅜-inch compression angle) to the interface on the solenoid. Then using an adjustable wrench, tighten the fitting so it faces toward the back of the dishwasher and slightly to the left. Attach flexible dishwasher water line (a 4-foot to 5-foot lenght of ⅜-inch OD supply tube) to the water line fitting.
Tip #5 Do not use rigid water line; it will not allow you to pull the dishwasher out for maintenance. First hand tighten the water line, then snug it with a wrench.
Installing The Electrical Lines
Tip #1 Remove the cover of the electrical box located near the front right bottom of the dishwasher. Attach an NM bushing in the cable hole on the electrical box.
Tip #2 Bring the ends of the cable (12-guage NMB cable with ground) through the bushing, and splice the wires to those already in the dishwasher. Use orange wire nuts (they’re the right size for this wire) to connect the wires of the same color – black to black, white to white, and ground to a metal ground screw or green wire.
Finishing The Installation
Tip #1 Return the dishwasher to its upright position, and start to feed the ends of the electrical cable, water line, and drain line through the holes you cut in the cabinet. Then push the dishwasher into the cabinet while a helper pulls the lines into the sink cabinet next door.
BONUS TIP: It is acceptable to let electrical cable and any extra water line loop up behind the dishwasher.
Tip #2 With the unit pushed completely in its cabinet, set a level on top of the front edge of the dishwasher.
Tip #3 Using a small open-end wrench, adjust the appropriate front leg(s) as necessary to bring the appliance level.
Tip #4 Only the front two feet should be adjusted.
Tip #5 Attach the dishwasher drain hose to the under-sink drain – its end will slip on a ½-inch nipple of any pipe material.
Tip #6 Each drain installation, of course, will differ in how the hose will attach to the sink drain, because there are a variety of possible drain fittings. In most installations, a master plumber will use a ½-inch nipple screwed into a threaded PVC bushing and a double-Y fitting.
Tip #7 Do not add a trap. A dishwasher uses the sink trap. Cut a T-fitting into the hot water line to the sink, add a stop valve, and attach the flexible water line fitting.
Tip #8 Bring the electrical cable to an electrical junction box on a dedicated 20-amp circuit. Then turn the water on and as the dishwasher fills, check for leaks.
Tip #9 If there are no leaks, secure the top of the dishwasher cabinet to the underside of the counter by driving the screws provided through the holes in the tabs on top of the dishwasher’s body.
WHAT CAN GO WRONG? If the dishwasher is not level, there will be an uneven level of water inside it, which may affect its cleaning action and the operation of the float switches.
Draining The Dishwasher
“There are many ways to drain a dishwasher,” says Beall. “If lucky, there will be a drain access in the existing drain. Or, if there is a garbage disposal, the side drain is always there, but a screwdriver will be needed to break out the plastic knockout.” Beall adds, “if none of these is available, it will become necessary to take apart the exiting drain and add a tail piece with access or replace the existing drain with an integral drain for the dishwasher.”
It can become quite complicated in some cases, don’t hesitate to call Mr Rooter in these cases. Leaky faucets, garbage disposal maintenance, installing dishwashers, washing machines and hot water tanks are standard requests from residential customers needing the services of a qualified Pittsburgh plumbing contractor.
