1.Product Introduction 1-1. Concept Active Fresh & Energy Saving
Harnesses pure silver’s sanitizing power, nano science, and the state-of-the-art technological competency of SAMSUNG. Two plates of 99.9% pure silver are converted into 4 million nano-sized particles through electrolysis and penetrate into the laundry blended with water. Even in cold water, silver nano-sized particles sanitize and remove 99.99% of odor-causing bacteria. Furthermore, this process sanitizes not only clothes but also the tub, thereby achieving a perfect ‘Superior Clean’ system. Washing garments with Active Fresh can save about 92% of energy compared to hot water sanitization. Also, Active Fresh Technology prevents damage to delicate clothes compared to sanitizing in hot water.

(14.2  7% Ohms) • Check the pump at CN10 (Pin6) on PCB. It should read AC 110~120V. (Refer to PCB Connector Check)

5-1. Troubleshooting Problem What To Do Load is too wet at the End of the cycle. • Unbalance due to not enough load. Put additional load. • Due to excessive suds by using general detergent. Use HE (High-Efficiency) or reduce its quantity. • Low Spin Speed or Drain Only was selected. • Go to “ Will Not Spin”.

5-1. Troubleshooting Problem What To Do Leaks water. Make sure there is no leakage in the inlet hose connections. • Check for rubber gasket damage due to over-tightening. • Check standpipe for leakage. Check if the standpipe contributes the leakage. If so, the standpipe is under-capacity. In this case, make sure to seal its opening tightly. • Check waster hose connections. (Water Supply/ Drain/ Dispenser Hose & Clamp) • Check if rubber boot is water-tight. • Check for any kink on the water hoses.

5-1. Troubleshooting Problem What To Do Excessive Suds • Go to “Will Not Drain” and “Will Not Spin” and check the draining. • Check PCB and Drain Pump for any loose wire connection. • Perform Quick Test Mode or Board Output Test to drain. • Use HE (High-Efficiency) or low sudsing detergent specially formulated for front load washers. • Reduce the amount of detergent for that specific load size and soil level. Keep in mind that towel creates more suds generally. • Reduce the amount of detergent when water is soft, or laundry is small or lightly soiled. • Do one more washing cycle with cold water and a table spoon of salt without detergent.

5-1. Troubleshooting Problem What To Do No Key Operation • Each washing selection deactivates some buttons. • Child Lock is being activated.
