    1. SAFETy INSTRUCTIONS 1-1. SAFETy INSTRUCTIOINS FOR SERvICE ENGINEERS ሪ Make sure to observe the following instructions to operate the product correctly and safely and prevent possible accidents and hazards while servicing. ሪ Two types of safety symbols, Warning and Caution, are used in the safety instructions. Warning Hazards or unsafe practices that may result in severe personal injury or death. Caution Hazards or unsafe practices that may result in minor personal injury or property damage. Warning Before Servicing (When servicing electrical parts or harnesses) Make sure to disconnect the circuit ࣃ breaker or power cable before servicing. ➢ Failure to do so may result in a risk of electric shock. Do not allow consumers to connect several appliances to a single power outlet at the ࣃ same time. ➢ There is a risk of fire due to overheating. When removing the power cord, make sure to hold the power plug when pulling the plug ࣃ from the outlet. ➢ Failure to do so may damage the plug and result in fire or electric shock. When the dishwasher is not being used, make sure to disconnect the circuit breaker or ࣃ power cable from the power outlet. ➢ Failure to do so may result in electric shock or fire due to lightning. Do not place or use gasoline, thinners, alcohol, or other flammable or explosive ࣃ...
  • Page 4 While Servicing Check if the power cable is damaged, flattened, cut or otherwise degraded. ࣃ ➢ If faulty, replace it immediately. Failure to do so may result in electric shock or fire. Completely remove any dust or foreign material from the housing, wiring and connection ࣃ parts. ➢ This will prevent a risk of fire due to arcing and short circuits in advance. When connecting wires, make sure to connect them using the correct connectors and ࣃ check that they are completely connected. ➢ If tape is used instead of the connectors, it may cause fire due to arcing. Make sure to disconnect the PBA power terminals before starting the service. ࣃ ➢ Failing to do so may result in a high voltage electric shock. When replacing the heater, make sure to fasten the nut after ensuring that it is inserted ࣃ into the bracket-heater. ➢ If the nut is not fastened correctly, it can cause a water leak. After Servicing Check for any water leakage. ࣃ ➢ Perform a test using the standard(normal) cycle and check whether there is any water leakage through the floor section or the pipes. Do not allow consumers to repair or service any part of the dishwasher themselves. ࣃ ➢ This may result in personal injury and shorten the product life. If it seems that grounding is needed due to water or moisture, make sure to run ࣃ grounding wires. ➢...
  • Page 5 Caution Before Servicing Do not sprinkle water onto the dishwasher directly when cleaning it. ࣃ ➢ This may result in electric shock or fire, and may shorten the product life. Do not place any containers with water on the dishwasher. ࣃ ➢ If the water is spilled, it may result in electric shock or fire. This will also shorten the product life. Do not install the dishwasher in a location exposed to snow or rain. ࣃ ➢ This may result in electric shock or fire, and shorten the product life. Do not press a control button using a sharp tool or object. ࣃ ➢ This may result in electric shock or damage to the product. During Servicing When connecting a wiring harness, make sure to seal it completely so no liquid can enter. ࣃ ➢ Make sure that the connections are securing by slightly pulling on them. Check if there is any evidence that liquid has entered electric components or ࣃ connections. ➢ If any liquid has entered into a part, replace it or completely remove any remaining moisture from it. If you need to place the dishwasher on its back for servicing purposes, place a support(s) ࣃ on the floor and lay it down carefully so the back is on the floor. ➢ Do not lay it down on its front or side. This may result in scratches to the surface or damage to the parts. Safety Instructions _ 3...
  • Page 6 After Servicing Check the assembled status of the parts. ࣃ ➢ They must be the same as before servicing. Check whether the product is level with the floor and secured to the cabinet and under ࣃ the counter. ➢ Vibrations can shorten the life of the product. 4 _ Safety Instructions...

    7-2. TERMINOLOGy Circulation Motor A motor that sucks the water remaining on the floor of the dishwasher and injects water using high pressure through the internal water passages to the top, middle and lower nozzles. Drain Pump The pump that drains the polluted water from the dishwasher generated while the dishwasher is running. Heater The heater is located on the water passages inside the dishwasher. It heats the flowing water to increase wash efficiency. Distributor Located at the output end of the sump inside the dishwasher. It turns the flow of the water that goes to the bottom part of the dishwasher on or off. Dispenser The location where the detergent and rinse aids are stored so they can be used by the dishwasher. The dispenser automatically supplies detergent and rinse aids to the inside of the dishwasher when they are needed. Tub Assy An internal case made of stainless steel that makes up the basic framework of the dishwasher. Sump Assy The place inside the dishwasher where water is collected. The injected water gathers here after circulation. The sump Assy is connected to the circulation motor, drain pump, and distributor motor. Tub Front Assy An internal case made of stainless steel that makes up the internal part of the front door. Basket Assy The upper and lower racks where dishes can be loaded. 10. Top/Middle/Lower Nozzles Washes dishes by rotating and injecting the supplied water through the water passages at high pressure. 11. Door Lock Switch Detects whether the door of the dishwasher is open or closed. If the door is open while the dishwasher is running, the cycle is temporary stopped.
