This article provides a detailed walkthrough, focusing on best practices and safety measures for U.S.-based users.
Preparing for Installation
Before beginning the installation of the LG LDPH5554S dishwasher, it is essential to prepare the installation site and gather the necessary tools. The following steps should be completed prior to unboxing the appliance:
- Turn off the water valve and circuit breaker. This is a critical safety measure to prevent water leaks and electrical hazards during installation.
- Verify the location of the water supply line, drain line, and power supply. The unit should be installed no more than 12 feet from the sink and drain lines to ensure proper drainage. The power supply should be accessible within 4 feet of the dishwasher’s side and not behind the unit.
- Use the provided template and manual to determine the clearance and location of the installation hole. If the cabinet cavity lacks openings, a 2 1/2" diameter hole saw should be used to drill a hole at the target location.
Once the site is prepared, the dishwasher can be unboxed. During this process, the following should be done:
- Remove all packaging materials from the unit. This includes any plastic wraps, foam inserts, or shipping braces.
- Remove the rear plastic shipping brace and the 2 screws attaching the lower cover. These components are used during shipping and must be removed to allow for proper installation.
- Extend the water supply line and power supply outward and loosely tape them to the floor. These should be positioned approximately 14 to 16 inches apart to allow for easy routing during installation.
Positioning and Connecting the Dishwasher
After preparing the site and unboxing the dishwasher, the next step is to position the unit and connect the supply lines. This process involves careful alignment and securing of the appliance to ensure safe and efficient operation.
- Position the unit closely in front of the water supply line and power supply. This allows for easy access to the inlet valve and junction box located toward the bottom front of the unit.
- Remove the tape from the water supply line and power supply, then pull both through the dishwasher's bottom openings. This should be done carefully to avoid kinking or bending the hoses.
- Slide the unit further back to reveal the water supply line and power supply. At this point, the inlet valve on the left and the electrical junction box on the right become accessible for connection.
To connect the water supply line:
- Connect the water supply line to the inlet valve and use a wrench to tighten firmly. A secure connection is essential to prevent leaks and ensure proper water flow during operation.
For the electrical connection:
- Ensure the dishwasher has a dedicated, properly grounded circuit. This is necessary for safe and stable power supply.
- If a 3-prong wire supply is used, it should be in an accessible location adjacent to the dishwasher. The 3-wire setup includes neutral, power, and the green ground wire.
- Use a Phillips head screwdriver to remove the screw from the junction box and install a strain relief onto the power supply. This prevents strain on the wires and ensures a secure fit.
- Insert the power supply into the junction box and secure it with a ring nut. The wires should be paired according to their corresponding colors and connected using wire caps.
- Wrap each wire cap with electrical tape to create a tight seal. This step is crucial to prevent short circuits and ensure a long-lasting connection.
- Reinsert the capped wires into the junction box and screw the junction box cover back into place.
Once the connections are complete, the dishwasher is ready to be moved into its final position.
Securing and Leveling the Dishwasher
After the dishwasher is connected to the water and power supplies, the next step is to secure and level the unit to ensure proper operation and prevent damage to the surrounding cabinetry or countertop.
- Adjust the rear of the dishwasher using a Phillips head screwdriver to lift or lower it as needed. This is done by turning the single screw located at the bottom center of the unit.
- To adjust the front of the unit, use a flat blade screwdriver to turn the front legs clockwise or counterclockwise. This allows for fine-tuning of the unit’s position.
- Ensure the gap between the door and the tub is equal on both the left and right sides. This helps maintain proper alignment and door closure.
- Use a leveling tool on the top front center of the unit to verify that it is level. The leveling should also be checked from the inside wall of the tub interior. Adjust as necessary until the unit is completely level.
For installation on a wood countertop:
- Secure the dishwasher using the screws and metal installation brackets provided. These are designed to attach the appliance to the underside of the countertop.
- Use needle nose pliers to bend the tabs on the brackets and tighten them firmly. This ensures the unit is stable and does not shift during operation.
- Be sure to cover the filter with towels to prevent screws from falling into the pump. This is a safety precaution to avoid damage to internal components.
For countertops made of materials like granite or marble, which may be damaged by drilling:
- Use the wood screws to attach the dishwasher to the side of the cabinet. This can be done by removing the plastic caps from the mounting bracket and securing the unit into the cabinet frame.
Once the unit is level and securely in place:
- Remove any remaining packaging materials. These are no longer needed and should be disposed of properly.
- Turn on the circuit breaker and water valve. This restores power and water supply to the dishwasher.
- Power on the dishwasher and run a cycle to test the installation. This ensures that all connections are secure and the unit is operating correctly.
Connecting the Drain Hose
A critical step in the installation process is connecting the dishwasher’s drain hose to the garbage disposal or the home’s drainage system. This ensures that used water is properly removed from the unit and does not cause damage or backflow.
- Before connecting the drain hose, remove the knockout plug on the garbage disposal using a hammer and wooden dowel. This allows the dishwasher to drain properly into the disposal.
- Attach the drain hose to the garbage disposal using the hose clamp provided. Use a flat blade screwdriver to tighten the clamp firmly.
- Feed the water drain hose into the cavity’s left side hole where the water supply line is located. This should be done carefully to avoid kinking or pinching the hose.
- Carefully pull on the drain hose while sliding the dishwasher in place to avoid slack or kinks. The hose should be fully seated and not sag or twist behind the unit.
If the dishwasher is not connected to a garbage disposal, the drain hose should be connected directly to the home’s drainage system. In either case, it is essential to follow the garbage disposal manufacturer’s manual for specific installation instructions to ensure compatibility and proper function.
Final Checks and Safety Considerations
Before completing the installation, it is important to perform a final set of checks to ensure that the dishwasher is installed correctly and operating safely.
- Verify that the water supply line and drain hose are not kinked or bent. A smooth flow of water is essential for proper cleaning and drainage.
- Ensure that all electrical connections are secure and properly insulated. This includes checking the wire caps and strain relief on the power supply.
- Confirm that the unit is level and securely fastened to the countertop or cabinet. An unlevel or unstable unit can cause vibration, noise, or damage to the surrounding area.
- Check that the door closes smoothly and aligns properly with the tub. If the door does not close correctly, the unit should be adjusted and re-leveled.
- Test the dishwasher by running a complete cycle. This allows for the final verification that all connections are working and the unit is operating as intended.
Safety is a primary concern during installation, so the following precautions should be taken:
- Always turn off the water valve and circuit breaker before beginning the installation. This prevents accidental water leaks and electrical shocks.
- Wear gloves and use proper tools to avoid hand injuries. The installation process may involve working with metal brackets, sharp edges, and electrical components.
- Use a stable surface and proper lighting to avoid slips or accidents. Working in a well-lit area with a stable floor helps prevent injury during the installation.
