Preparation

dishwasher installationPrepare the dishwasher and the connections for the dishwasher installation. Paint the enclosed sides of the kitchen cabinet where the dishwasher will be fitted with a moisture-proof or oil-based polyurethane paint in order to prevent damage from any moisture or steam warping the wood. Install a 20-amp circuit from the circuit breaker panel, if there isn’t already one fitted. The circuit breaker must be turned off and all power disconnected. Turn off the water supply valve and drain off all water from supply lines before setting up water connections. Have this dishwasher installation guide handy!

Step One – Locate the two front-to-back paths on the underside of the dishwasher to position the water and electric lines. These must be away from the motor of the dishwasher, as the motor wires run from the back to the front. Measure the distance of both paths from the sides of the dishwasher, and then transfer these measurements to the floor of the bay. Using the tape, secure the copper tube and the electrical wire in the marked positions on the floor.

Step Two – Connect the drain tube to the sink drain. All water must drain into a waste pipe or trap above the level of the drum. The connect water supply tube to the water pipe underneath the sink. This step should always be carried out this order, firstly to reduce the chances of flooding, and secondly by facilitating leak testing without the potential for shocks. Restore the water pressure in order to check for leaks, but do not exert too much pressure whilst doing this check, as it may damage the page.

Step Three – Tilt the dishwasher onto its back, on top of a waterproof canvas or sheet if possible. Remove the bottom cover and wrap tape around the water inlet threads. Screw a brass elbow to the inlet and tighten using one of the wrenches. Return the dishwasher right-side-up, and then push it into the cabinet bay where it will be positioned.

Step Four – Check water and electrical alignments. Make a hole in the side of the cabinet, then pass the end of the drain line through the side of the cabinet upwards through this hole.

Step Five – If there are any exposed wires, these must be covered. Plastic covering will ensure the electrical wires are sufficiently protected, and they need to be clamped and bundled properly with a clamping bracket. The clamp prevents electrocution if, by chance, there are any leaks within the dishwasher.

Step Six -Unscrew the star-shaped nut, then push wires through the threaded ends of the clamp, which passes through a hole in the unit junction box.

Step Seven – Match up the colours. White wire meets white, black wire meets black wire, and so on. Tighten them with wire nuts.

Step Eight – Turn on the power and water supply to check leaks. Press start on any dishwasher cycle, and allow it to fill with water. Press cancel and the unit will drain. If any leaks appear, turn all power and water back off and then tighten fittings.

Step Nine – Install base plates to the dishwasher. Secure the dishwasher to the countertop with screws if necessary.

Hints and Tips

dishwasher installationWhen buying a dishwasher, examine it thoroughly before you bring it back home and attempt to fit it. Faulty parts could be disastrous, whilst scratches and dents will ruin the aesthetic of the appliance and its resale value if you decide to upgrade to a newer model at a later date. Make sure all the necessary hardware and tools are installed. If disconnecting an existing machine in order to replace it, have some towels and a bucket on hand to drain any water left in the lines before fitting the new dishwasher.

The process is simple enough if the steps are followed to the letter, but those who do not feel assured enough by their own DIY skills are advised to contact a professional dishwasher fitter, who will be happy to carry out the job in less time than it would take to do it yourself. In a situation where the location of the dishwasher is being moved, it is best to call out a plumber who will be able to advise on pipes, positioning and other vital considerations.
