On an agitator top-loader like this, loading is the usual cause. Do not wind sheets, towels and long items around the center agitator post, do not load above the top of the agitator, and balance the load around it. Use enough water for the load (a deep-fill or higher water level for bulky items) and the correct cycle. Poor cleaning is far more often loading and detergent than a mechanical fault.
