Our Samsung front loader (model WF210ANW/XAA) won\'t fill at the start of a wash cycle. The washer starts out by humming like it is going to fill but no water enters. it then automatically locks the door and starts to agitate. No error code. It will fill with water when set to rinse. The filling has nothing to do with water temp and I checked the water inlet valves--they have a normal Ohms reading. I broke the water level sensor while checking it so it\'s new now as well.
