Check the simple causes first: load balance, water supply, drain flow, door or lid closure, visible leaks, and power stability. Inspect accessible wiring connectors and moisture-prone areas before assuming the control board has failed. Use the complete Samsung washer model number from the door, lid, or rear tag before matching any pump, valve, sensor, suspension, lock, or board category.
