My washer stopped filling...?

It's a Kenmore Laundry Center. I filled it with a few pairs of jeans and 4 shirts, so it wasn't overloaded. I set the water level to medium and walked away to let it do it's thing. Only I noticed there was no water pressure (not only to the washer, but to the whole house), so I opened the lid and pulled the knob out to stop the cycle. Turns out there is some construction in town and a pipe burst, so when the water pressure came back up, I re-closed the lid ans pushed the knob in to resume the cycle. The machine filled for a few seconds and then stopped. Now every few minutes it just hums, won't continue filling and won't agitate. I took the clothes out but now I have a machine partially full of water...what do I do? Is there a cycle reset button? Any ideas as to what the problem could be?
