As with all equipment using electricity, water and moving parts, potential hazards exist. To safely operate this appliance, become familiar with its operation and exercise care when using it.The dishwasher must be properly grounded. Never connect it to an ungrounded outlet. Prior to removal of original dishwasher and the installation of your new unit, make sure to switch off your circuit breaker. Do not connect the dishwasher until you have completed the installation. Connecting the power cable is the last step when installing the dishwasher.
All wiring and grounding must be done in accordance with the electrical code applicable to the region.


For a permanently connected appliance
This appliance must be connected to a grounded metal, a permanent wiring system, or an equipment-grounding conductor must be run with the circuit conductors and connected to the equipment-grounding terminal or lead on the appliance. The dishwasher is very heavy. Do not attempt to move or carry a dishwasher alone. Two or more people are needed to move a dishwasher and avoid potential injuries.

  •  Do not touch the power cable with wet hands.
  • Do not connect another appliance to the same power outlet as the dishwasher.

Make sure to use a new water supply line. Old lines are susceptible to breakage because they become hardened and may cause property damage due to a water leakage. The dishwasher must be connected to a hot water supply with a temperature between 120 “F (49 “C) – 149 °F (65 “C). This temperature range provides the best washing result and shortest cycle time. Temperature should not exceed 149 “F (65 “C) to prevent damage to dishes. Ensure that the water supplied to the dishwasher does not freeze. Frozen water can damage the hoses, valves, pump, or other components. Certified residential dishwashers are not intended for licensed food establishments(NSF/ANSI Standard 184 for Residential Dishwashers) For a full list of safety information, please refer to the User Manual.

installing the dishwasher

Be sure that you or your installer follow these instructions closely so that the new dishwasher works properly and that you’re not at risk of injury when washing dishes.


Before starting on the installation, prepare all the necessary tools and parts required to install the dishwasher. This will save installation time and simplify the installation process.

For the hot water supply line – We strongly recommend using ⅜” minimum O.D. copper tubing with a compression fitting or a flexible stainless steel braided hot water supply line. Do not use plastic tubing. Plastic tubing can deteriorate over time and cause a leak inside the tube fitting.
You also need a 90° Fitting with ¾” N.P.T. external pipe threads on one end and a fitting sized to fit your hot water supply line (copper tubing/compression fitting or braided hose) on the other. For the power cable, we recommend a jacketed 12-2 cable with ground. Note that some local codes may require the cable to have a BX style metal jacket.
