I have a Samsung Dishwasher (DMR57LFS). My wife put old golf balls in it to wash and clean. One ball cover came off and the rubber got around the impeller shaft and stopped the motor. I cleaned out the rubber and freed the shaft of the motor so that it spins freely now. But the letters LE still comes on. I turned off the power and then after a couple of days I plugged it in but it still flashes the letters. How can I reset the DW so that it will run?
