Front load washer spins and rinses but won't wash!

My Samsung front load washer gets stuck right after it initially fills with water. The normal cycle is 1:09 and at 1:07 it stops and starts humming. The humming sounds like its trying to pull water in, but I could be wrong about that. I replaced the water inlet valve, but I don't think that was ever the issue because the Rinse & Spin cycle works just fine, as does the Spin Only cycle. The quick wash cycle, just like the normal cycle, will not work.
