Installing a built-in dishwasher requires basic mechanical, electrical, and plumbing skills, so the average handy person can put in a dishwasher in 1 to 3 hours depending on if it is a new installation or a replacement dishwasher. If you are replacing an existing dishwasher, it is going to take less time.
- Prepare the cabinet area where the dishwasher is going to be set up. The opening should be 24 inches wide for many versions, 24 inches deep and 34 1 or2 from the ground to the bottom of the countertop. The back wall may not have wires or pipes on it. This dishwasher installation rowville process makes easier in different places. The power and water distribution lines will come in the cupboard in the 4X4 area in the bottom rear of the cabinet via a 1 1 or2 hole. Make sure that the floor is flat and the cupboard is squared.
- Select your drain method based on the Local codes and height of the drain tee. Some codes require an air gap. If the drain tee shirt is less than 18 inches from the ground, you need to use an air gap. If an air gap is not required and the tee is over 18 inches from the ground, you can use the loop way of the drain connection. If the drain hose will be connected to a garbage disposal, you need to eliminate the knock out plug so the dishwasher will drain.
- Inspect or install wiring by making sure there is a 120V, 60Hz dedicated circuit with a 15 or 20-amp breaker or time delay fuse. If it is a flexible power cable, it has to have another hole. Hardwiring cable will come up the right side across the bottom 24 inches of the cupboard to the ideal front electric connection on the dishwasher.
- Prepare the water supply line which enters through the 1 1 or2 Holes in the rear base of the cabinet. Turn off the water to put in a hand shut-off valve under the sink. The water connection is on the left side of the dishwasher. Use 3 or8 O.D. copper line to extend no less than 19 inches from the back wall. The water heater should be set between 120 and 150 levels nearer to 120 if children are in the house to prevent scalding accidents and the pressure should be between 20-120 PSI.
Replacing an Existing Dishwasher
You would not need to drill the holes because they will be there from the present dishwasher. But you do need to inspect the wiring and plumbing to be certain they are capable of servicing the new dishwasher. Use a catch pan when disconnecting the water supply line. After all of these lines and wires are disconnected, it is possible to take out the brackets and screws that Hold the dishwasher at its location and carefully pull out the old dishwasher.
