Before removing the old dishwasher. Review the instructions for how to install a dishwasher. Usually, it lists specific details on your new machine, for instance, extra parts that could be needed for the appliance or additional materials and tools needed. Turn off the electricity for the dishwasher from the circuit breaker, always inspect the to make sure the power is off. To do so check the voltage breaker. Next, shut off the water from the “shut-off valve” located under the sink. Using a screwdriver remove the clay board panel close to the floor and detach the wires from the old dishwasher found in the terminal box. Use the adjustable wrench to detach the old water line from the dishwasher. In order to prevent water leakage after removing the nuts, place a bowl under the connection; preferably a small shallow bowl. Detach the hose from the dishwasher and remove the screws placed on the bottom of the countertop and side cabinets.

To avoid spoiling the floor, place an old blanket, rug, or cardboard on the floor in front of the dishwasher. Then, carefully drag the old dishwasher from its current setting and position it away. Finally, using masking tape, bind all electrical connections to ensure no disturbance occurs when putting the new dishwasher. 

Step 2: Preparing the new dishwasher 

Unbox the new dishwasher following the manual instructions. After unboxing, review the installation process on how to install the dishwasher. Note the directions might differ from the following listed above. Then, place the dishwasher on its back to allow an easier connection and plumbing access. Connect the new 90-degree fitting found in the dishwasher kit to the water valve. Do not reuse old fitting for a smooth installation. Next, detach the old water line from the shut-off valve and place the new water line found in the installation kit in the hole in the middle of the kitchen sink and dishwasher location. To eliminate flooding, curve the flexible line to the very bottom of the dishwasher. Then, tape the new water line on the floor of the dishwasher location to eliminate any movement when pushing the new dishwasher into place.

For the drain hose, separate the old drain hose from the sink pipe or disposal. Take out any water inside the dishwasher using a sponge before the removal of the drain line. Connect the new hose through the same route as the water line – the hole in the middle of the sink and dishwasher location. Finally, seal the new drain hose to the floor then attach it to the sink pipe or disposal.

Connect and secure the drain hose to the back end of the sink. If you have metal/aluminum wires call a certified plumber or electrician. Aluminum wires are dull and gray.

Step 3: Attaching Water, Drain, and Electric

Standing the new dishwasher up, gently glide it into place. Position your hands on the side of the dishwasher, tilt it slightly upward and roll it into the dishwasher space. Do not fully secure the countertop. Use an old cloth or rug to prevent floor damages. Then, connect the 90-degree fitting to the water line and use your piler to tightly install, then connect the drain hose based on information provided in the manufacture label. Next, check for leakage and by turning on the water supply, install more tightly if needed. Finalize all electric connections using wiring nuts and guides.

Step 4: Final adjustments 

After attaching the waterline, drain hose, and power. Use the circuit breaker mentioned in step 1 to turn on the electricity and check the newly installed appliance operation before fully positioning it into place. Make sure the dishwasher is lined upfront with the sink cabinets. Ensure the unit is leveled and that plumbing is correct. Use a level for this process.

Tighten the bolts and nuts and check the dishwasher position and perform adjustments as needed. Then, replace the front in-clay panel.

How to Replace a Dishwasher: Conclusion 

To sum it up, these steps are detail-oriented and may take a couple of hours, however, installing your very own dishwasher saves you from excessive plumbing charges and makes challenging tasks seem possible. Every time you start a load in your newly installed appliance, take a second to enjoy your labor, strong determination, and resilience.

Happy washing!
