User Manual Samsung WW90T554DAN/S1 Ww5500 Washing Machine

Do not overload the washer. If the washer is overloaded, detergent may not reach all of the clothes in the load, resulting in lower cleaning performance. If the washer is underloaded, it is very likely that too much detergent will be used, still resulting in poor cleaning performance (see Step 2).

To fix a Samsung washer that won't start or stop, check for a malfunctioning door lock, thermal fuse, or line fuse. Also, look for a defective display board, inadequate main control or logic board, broken power cord, clogged debris filter, kinked hoses, or an imbalanced wash load.
