NOT COMPLETING THE FINAL CYCLE

Hello, you may need to actually replace the drain pump. Sometimes the impeller is stripped on the shaft. Also there should be an error code. I have attached 3 videos on Samsung error codes and how to enter into diagnostics mode. You may have a hall sensor issue. It is mounted on the stater drive motor. If no errors are displayed it is difficult to determine your issue. Also I know that this is a strange method to get higher spin speeds but if you set unit to medium speed it will start out slower and allow the clothes to tumble into a more even position and allow for better spin. The first thing you need to do is to get the machine into diagnostics and see if there are any error codes stored to give you an idea of where to begin. There is very limited resources available for this model and hopefully a stored error code will shed some light on the failure.
