Mr Rooter’s tip of the day

Installation of water pipes

Tip # 1 On the side of the dishwasher cabinet closest to the sink and on the back just below the countertop, drill a 1 ½ 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 screws or ¼ inch hex head screws) that hold the skid plate (the plate immediately under the door).

Tip # 3 Set the plinth aside and don’t bend or scratch it. This exposes the area in which connections for water and power lines can be found; the water line solenoid is on the left and the electrical connections are on the right. Make sure the drain hose is already attached to the dishwasher pump; if not, secure it with the clamps supplied with the washer for this purpose.

Tip # 4 Look for the dishwasher solenoid on the lower left. You will recognize the female inch thread attached to it. This is where the water line connection goes. Hand tighten the water line fitting (⅜ inch compression angle) at the interface on the solenoid. Then, using an adjustable wrench, tighten the fitting so that it faces towards the back of the dishwasher and slightly to the left. To attach flexible water pipe for dishwashers (a 4 foot to 5 foot ⅜ inch outside diameter supply tube) to the water line fitting.

Tip # 5 Don’t use a rigid water line; it will not allow you to remove the dishwasher for maintenance. Tighten the water line by hand first, then tighten it with a wrench.

Installation of power lines

Tip # 1 Remove the electrical box cover located near the bottom right front of the dishwasher. Secure an NM socket in the cable hole on the electrical box.

Tip # 2 Thread the ends of the cable (12 gauge NMB cable with grounding) through the socket and connect the wires to those already in the dishwasher. Use orange wire nuts (they are the correct size for this wire) to connect wires of the same color – black to black, white to white, and ground to a metal ground screw or to a green thread.

Finish the installation

Tip # 1 Return the dishwasher to an upright position and begin feeding 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 an assistant pulls the lines into the sink next door.

BONUS TIP: It is okay to let the electrical cable and any extra water lines wind up behind the dishwasher.

Tip # 2 With the appliance fully seated in its cabinet, place a level on the front edge of the dishwasher.

Tip # 3 Using a small open-end wrench, adjust the appropriate front leg (s) as needed to level the unit.

Tip # 4 Only the two front feet need to be adjusted.

Tip # 5 Attach the dishwasher drain hose to the drain under the sink – its end will slide over a ½ inch nipple of any pipe material.

Tip # 6 Each drain installation, of course, will differ in how the pipe attaches to the sink drain, as there are a variety of possible drain fittings. In most installations, a master plumber will use a ½ inch nipple screwed into a PVC threaded socket and a double Y fitting.

Tip # 7 Don’t add a trap. A dishwasher uses the sink trap. Cut a T-fitting in the hot water line to the sink, add a shutoff 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 on the water and as the dishwasher fills up, 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 provided screws into the tab holes on the top of the dishwasher body.

WHAT CAN BE DONE? If the dishwasher is not level, there will be an uneven water level inside, which can 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 you’re lucky, there will be drain access in the existing drain. Or, if there is a garbage disposal, the side drain is still there, but a screwdriver will be needed to punch the plastic hole. Beall adds, “If none of these are available, it will become necessary to disassemble the outlet drain and add a nozzle with access or replace the existing drain with an integrated drain for the dishwasher.

It can get quite complicated in some cases, feel free to call Mr Rooter in these cases. Leaky faucets, maintenance of garbage disposal, installation of dishwashers, washing machines and hot water tanks are common requests from residential customers requiring the services of a qualified Pittsburgh plumbing contractor.
