Dishwasher Installation How to Properly Install a Dishwasher
Proper installation is critical to the longevity of your dishwasher. If you skip steps or don’t complete the job correctly, water leaks may damage your cabinets, floors, and walls. In addition to the cost of fixing those problems, they can also cause rot, mold, and other issues that you will want to avoid.
Precise measurements are essential, and it is best to take the time to do them correctly. A few extra minutes up front can save you the cost of replacing a dishwasher later. It is also important to measure the height, width, and depth of your cabinet opening multiple times to make sure that you have accurate information about what size dishwasher will fit in the space. If you do not, you may find yourself ordering a replacement that doesn’t properly fit, or trying to install it and having to remove the new appliance later.
Before you begin your dishwasher installation, shut off electricity to the circuit breaker and turn off the water supply valve under the sink. This will prevent electrical shock and water damage. Once the dishwasher is in place, you can reconnect the supply lines and drain hose. Be sure to use a quality, stainless steel water line that is rated for dishwasher use and install the air gap as required by local plumbing codes.
If you are using a new dishwasher, open the box and remove any styrofoam or wrap that is protecting the unit. Tip the dishwasher on its back to make the electrical wiring and drain connections easier to access. If your model has a drip tray sensor, remove the sensor and set it aside for now. Remove the kickplate at the base of the dishwasher to expose the junction box, and remove the cover. Identify the three exposed wires on the power cord, and connect them to the corresponding terminal connectors in the junction box. If needed, apply Teflon tape to the male threads of the supply line and the drain hose to prevent leaks. Route the drain hose and power cord underneath the rear legs of the dishwasher.
Once the connection points are secure, you can push the dishwasher into the cabinet and tighten the anchor brackets. Then, use a level to check that the dishwasher is perfectly level from front to back and side to side. If it isn’t, you can adjust the front leveling legs to stabilize the dishwasher.
After the dishwasher is in place, you can replace the kickplate and the dishwasher’s front access panel. Plug in the power cord, and test the machine by turning on the water and running a load of dishes. If you are happy with the results, your dishwasher is now ready to use! If you notice any problems during the test run, such as a leaking or slow drain, consult your owner’s manual for tips on troubleshooting and repair. Be sure to follow the recommended maintenance schedule, as well, to keep your dishwasher operating at peak performance.
