** Check the water pump for obstructions before deciding to purchase additional parts **
My wife and I own a SAMSUNG DW80F600UTS which started flashing the SMART Auto/Heavy lights while the inner tube was full of water. I drained the machine, disassemble the "saucer", cleaned all components looking for foreign objects and couldn't find anything out of place, so I reassembled it. I flipped the machine on the side, took cover off and gain access to the ECS Sensor. It seemed in good shape (not cracked, burned, etc.) so I removed it, cleaned it and plugged it back in.
As I was about to replace the cover, I decided to take a look at the water pump to ensure it was clean. Once I removed it (twist and pull out) I found a piece of small bone
which somehow had managed to logged itself in the propeller fins and the side wall, no doubt keeping the pump from turning. We had chicken for dinner the night before (my sons are very notorious for not rinsing the dishes prior to placing them in dishwasher) so I realized this could be the problem.
I removed the bone and rotated the fins to ensure the motor was not turning too loose...it seemed fine. I reassembled everything, left machine outside cubicle, connected all hoses and power, turned it on or "NORMAL" cycle and it completed it successfully. I then ran the other cycles (Auto, Heavy and Delicate) and all were completed.
Hope this helps...and don't forget to remind the young ones to RINSE THE DISHES before loading the machine (LoL).
