Initially we discovered the LE code was due to water in the base due to the over flow. Of course my warranty was up and 1 month later the DW finally stopped with this error. We pulled out the DW and soaked up the water in the sensor on the right side base where it collects water. This got rid of the LE error code. The LE error kept making the drain go constantly so we had to turn off the power in order to stop the draining. The drain activity would go constantly even after opening the door due to the sensor on the right base being collected with water. I suppose I could have let it evaporate, but that would have taken at least 3 days. After that error, the DW did not start after initial start of filling of water. I observed the left side case assy collect water then suddenly stop washing flashing an OE error code. The support team at appliance parts emailed me a samsung service manually to help explain all the error codes. I assessed it could have been the case assy part so I ordered and replaced this part. Possible issue could have been the water level sensor in the case assy part. This did not work so I was very concerned and VERY ANGRY at Samsung. Samsung helpdesk was not very helpful..
I then read the part could be related to the water inlet valve sensor. BINGO!!! that was it. I replaced that valve which was some what of a pain because it required me to use tamper proof star bit which is not sold anymore in all hardware store. I finally replaced it and the DW worked. I could have returned the case assy, but decided not to mess with it and keep the original as a backup. maybe the issue was was more then 1 sensor, but I didn't want to touch it again. My wife was in disbelief I fixed the DW. I was a hero :) .
