This is the ultimate guide for safely installing a dishwasher. We provide detailed, step-by-step instructions to ensure proper and safe installation. Installing a new dishwasher involves connecting various water hoses and the power supply. On top of this, you will need to secure it in place with brackets or screws.
Most people possess tools like screwdrivers and pliers, enabling them to install a new dishwasher themselves. The only potentially challenging step is connecting the power supply if it is hardwired. If you lack experience with electrical wiring, we recommend hiring an electrician to connect the power.
Before we explain how to install a new dishwasher, we will give you step-by-step instructions on removing the old one.
How to remove a dishwasher
Before installing your new dishwasher, you need to remove the old one. You can skip to the installation section if you have already done this. Removing a dishwasher is pretty straightforward unless the power supply is hardwired, in which case you may need an electrician to do that part for you.
Follow these steps for how to remove your old dishwasher:
- Switch the power off. The first step is to turn the power supply off. You can either switch off the power socket or turn off the circuit breaker that supplies power to your dishwasher.
- Switch the water off. The next step is to turn the water supply off. You can then disconnect the water supply line from your dishwasher. This will involve using a pair of pliers or a wrench to loosen the connection points.
- Disconnect the drain hose. Once the power is turned off and the water supply line disconnected, you can then disconnect the drain hose from both ends. The drain hose will be connected to your sink drain or the garbage disposal unit. It will likely be secured with hose clamps that you must disconnect.
- Disconnect the power. The next step is to disconnect the power. If your dishwasher is plugged into a power socket, you can simply unplug it. If your dishwasher is hardwired, you will need to switch off the circuit breaker and then disconnect the wires. Make sure you have experience working with electrical wiring if your dishwasher is hardwired, as it can be very dangerous.
- Unsecure your dishwasher. If your dishwasher is held in place with brackets or screws, you will need to unthread them. You may also need to adjust the dishwasher legs to lower the height if necessary.
- Pull your dishwasher out. You can then pull your dishwasher out from the wall or the cabinet it’s in. Be careful not to damage your floor when pulling it out.
- Clean up. Before installing a new dishwasher, clean the area where it will go.
Steps to install a dishwasher safely
Installing a new dishwasher safely is relatively straightforward, but if you’re uncomfortable or inexperienced with disconnecting water hoses, consider getting a technician’s assistance. For hardwired power supplies, seek an electrician’s help if you’re not comfortable or experienced with electrical wiring. Additionally, be aware of local building codes to ensure correct installation according to regulations.
Follow these steps to install your dishwasher safely:
- Get prepared. Before installing your new dishwasher, ensure the area where it will go is clean, and there is nothing in the way that will prevent you from installing it. It’s also a good idea to ensure the power and water supply are both turned off.
- Move your dishwasher into position. Place the dishwasher close to where it will go so you can install the water supply hoses to the back of the appliance. You will need to ensure you have enough space to work in.
- Connect the drain hose. The next step is to connect the drain hose to the sink or garbage disposal unit. You can then install the other end of the hose to the dishwasher. The hoses will need to be secured in place with hose clamps.
- Connect the water hose. Once the drain hose is connected, you can connect the water supply line to both ends. You can then tighten the connection points with a pair of pliers or a wrench.
- Connect the power. You can now plug the dishwasher in or, if hardwired, connect the wiring up.
- Position the dishwasher. You can now push the dishwasher into position.
- Make sure the dishwasher is level. Place a bubble level on top of the dishwasher to ensure it sits level on the floor. If not, adjust the legs until it is.
- Secure the dishwasher. You can now secure the dishwasher to the countertop using screws or brackets.
Turn the dishwasher on. The final step is to turn the power and water supply on. Once turned on, run your dishwasher through a short cycle to ensure it’s working correctly. If everything is working correctly, you can start using your brand-new dishwasher!
