Frigidaire Affinity front load washer (LAFW7000LWD about 10-11 years old) just shows "sensing" and makes a humming sound when I try to start a cycle. It was working okay last night. I tried to start a load today and this happened. I've tried choosing "spin only" and it displays "draining" but just hums and doesn't do anything. I've tried unplugging it for awhile and plugging back in. There has been a small amount of water under the washer on occasion in the past but that doesn't happen with each load. I'm wondering if it has to do with the coin trap or drain pump? Door lock?
