My Frigidaire Washer FWT449GFS1 won't fill with water and just hums when I turn it on. It's a front loading wash machine. I replaced the door latch (the part that is attached to the door) and the intake valve as that seemed to be the predominant recommendation but still just humming when I turn it on. Would love to hear thoughts about what else it might be as we are piling up the laundry! Thanks!
