WASH PROGRAM ACTION The paragraphs below explain the motor operations for the various wash programs. Presoak No tub action while filling. After filling, clockwise 3 seconds on, 27 seconds off, counterclockwise 3 seconds on, 27 seconds off. Then 10 minutes of no tub action. Prewash Clockwise 9 seconds on, 6 seconds off, counterclockwise 9 seconds on, 6 seconds off, and so on. Normal wash Clockwise 12 seconds on, 3 seconds off, counterclockwise 12 seconds on, 3 seconds off, and so on. Synthetic wash Clockwise 3 seconds on, 27 seconds off, counterclockwise 3 seconds on, 27 seconds off, and so on. Wool/Hand wash Clockwise 3 seconds on, 57 seconds off, counterclockwise 3 seconds on, 57 seconds off, and so on. Fluff (at end of program) Clockwise 12 seconds on, 3 seconds off, counterclockwise 12 seconds on, 3 seconds off, and so on. Washing cycle 40 ± 1 rpm Presoak, prewash. 49 ± 1 rpm Main wash, rinses. SPIN SPEEDS W600: 800 or 1000 rpm W620: 600-1200 rpm * W640: 600-1400 rpm * W660: 600-1600 rpm * * Selectable in 100 rpm steps. OUT-OF-BALANCE CHECK There are two spin sequences, long and short. Both consist of a preliminary spin, the washing cycle and a main spin. Before the preliminary spin, the machine runs a separating cycle at 100 rpm and measures the drum MOTOR OPERATIONS speed on the way up and down. This checks for out-of-balance. During this cycle the tub may make violent movements although there is nothing wrong. There are three different limit values for out-ofbalance that permit different spin drying speeds. Limit value 1: 1300 - 1600 rpm Limit value 2: 1000 - 1299 rpm Limit value 3: - 999 rpm Preliminary spin (long and short) A preliminary spin dry is performed so that the machine will have a smoother start for its main spin dry cycle. It does this by removing over half the weight in water by spinning at 900 rpm for approximately one to two seconds. A maximum of ten restarts are made at limit value 3 to reach 500 rpm. If the out-of-balance is still too great in the final (tenth) attempt, the program will continue without the preliminary spin or main spin dry cycles. This is indicated on the display after the program has finished. Selected spin speed 1300-1600 (long and short) A maximum of five restarts at limit value 1 are made to try to achieve the selected spin drying speed. If the out-of-balance is too great, a maximum of three restarts will be made at limit value 2 to try to achieve 1200 rpm. If limit value 1 is achieved during any of these three restarts, the selected spin speed will be run. If the out-of-balance is still too great, a maximum of two restarts at limit value 3 will be made to try to reach 900 rpm. If limit value 2 or limit value 1 is achieved during either of these two restarts, 1200 rpm or the selected spin speed will be run. If the out-of-balance is still too great in the final (tenth) attempt, the program will continue without spin drying. This is indicated on the display after the program has finished. Selected spin speed 1000-1300 rpm (long and short) A maximum of eight restarts at limit value 2 are made to try to reach the selected spin drying speed. If the out-of-balance is too great, a maximum of two restarts will be made at limit value 3 to try to achieve 900 rpm. If limit value 2 is achieved during either of these restarts, the selected spin drying speed will run. 7
