WARNING WHILE SERVICING • Check if the power plug and outlet are damaged, flattened, cut or otherwise degraded. 4 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 connection parts. 4 This will prevent a risk of fire due to tracking and electrical hazard.. • When connecting wires, make sure to connect them using the relevant connectors and check that they are completely properly. 4 If tape is used instead of the connectors, it may cause fire due to tracking. • Make sure to discharge the PBA power terminals before starting the service. 4 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 into the bracket-heater. 4 If not inserted into the bracket-heater, it touches the drum and causes noise and electric leakage. WARNING AFTER SERVICING • Check the wiring. 4 Ensure that no wire touches a rotating part or a sharpened part of the electrical harness. • Check for any water leakage.

CAUTION BEFORE SERVICING • Do not sprinkle water onto the washing machine directly when cleaning it. 4 This may result in electric shock or fire, and may shorten the product lifetime. • Do not place any containers with water on the washing machine. 4 If the water is spilled, it may result in electric shock or fire. This will also shorten the product lifetime. • Do not install the washing machine in a location exposed to snow or rain. 4 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. 4 This may result in electric shock or damage to the product. CAUTION WHILE SERVICING • When wiring a harness, make sure to seal it completely so no liquid can enter. 4 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 harnesses. 4 If any liquid has entered into a part, replace it or completely remove any remaining moisture from it. • If you need to place the washing machine on its back for servicing purposes, place a support(s) on the floor and lay it down carefully so its side is on the floor. 4 Do not lay it down on its front. This may result in the inside tub damaging parts. Safety Instructions _ 3 Downloaded from Hudson Washer.indb 3...

CAUTION AFTER SERVICING • Check the assembled status of the parts. 4 Now is a good time to inspect your work. Review all connections and wiring, including mounting hardware. • Check the insulation resistance. 4 Disconnect the power cord from the power outlet and measure the insulation resistance between the power plug and the grounding wire of the washing machine. The value must be greater than 10MΩ when measured with a 500V DC Megger • Check whether the washing machine is level the floor with respect to the original position of the washing machine prior to service. By doing this now will reduce for the need of customer dissatisfaction and redo call.
Digital Inverter Motor direct-drive motor generates a higher spin speed for more effective, quiet operation. The washer also has fewer moving parts, meaning fewer repairs. • A separate nozzle has been adopted that sprays water equally so that the Mist Shower rinse cycle is effective even with a small amount of water. • This Samsung washer performs smoothly at top spin speeds, minimizing ® (Vibration Reduction Technology) noise and vibration. Eco Plus • If you select this option, the water temperature is set to slightly lower than (WA456*) during the normal wash course to save energy.
