Safety Instructions _ 1 1. SAFETY INSTRUCTIONS 1-1. SAFETY INSTRUCTIONS FOR SERVICE ENGINEERS Make sure to observe the following instructions to operate the product correctly and safely and prevent possible ሪ accidents and hazards while servicing. Two types of safety symbols, Warning and Caution, are used in the safety instructions. ሪ 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. Failing 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 ࣃ the 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 ࣃ the plug from the outlet. Failing 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 ࣃ breaker or power cable from the power outlet. Failing 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 substances near the dishwasher. There is a risk of explosion and fire caused from electric sparks.

2 _ Safety Instructions While Servicing Check if the power cable is damaged, flattened, cut or otherwise degraded. ࣃ If faulty, replace it immediately. Failing to do so may result in electric shock or fire. Completely remove any dust or foreign material from the housing, wiring and ࣃ connection parts. This will prevent a risk of fire due to tracking and shorts in advance. When connecting wires, make sure to connect them using the relevant connectors ࣃ and check that they are completely connected. If tape is used instead of the connectors, it may cause fire due to tracking. Make sure to discharge the PBA power and capacitor terminals before starting the ࣃ service. Failing to do so may result in a high voltage electric shock. When replacing the heater, make sure to fasten the holder heater after ensuring ࣃ that it is inserted into the bracket-heater. Ensure the heater is fitted into the bracket - heater correctly. After Servicing Check for any water leakage. ࣃ Perform a test run for the dishwasher 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 ࣃ themselves. This may result in personal injury and shorten the product lifetime.

Safety Instructions _ 3 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 lifetime. 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 lifetime. 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 lifetime. 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 wiring a harness, make sure to seal it completely so no liquid can enter. ࣃ Make sure that they do not break when force is exerted. Check if there is any residue that shows that liquid entered the electric parts or ࣃ harnesses. 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 ࣃ support(s) 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.
