Washer won't spin or agitate

Hi,

Washer started out shaking alot. Then started walking around. Then thumping noise at start of spin cycle.

Now it fills fine, drains fine, but no movement at all. No agitating or spinning.

When you have it powered, it hums loudly and makes a wind down hum when power is intterupted.

Lid switch is ok and it is getting power.

Thanks,
Brett
