Won’t spin or drain

It's an older washer. My fiance washed a blanket in it and it was off balance. Now it's full of water and won't drain or spin. But it does agitate. I'm at work, or I could tell you the model number/manufacturer. But the only controls are a two position rotary switch for load size (I think the bigger load is called super) and a knob for switching between about three or four different cycles. Searching online, I tried unplugging for a minute and opening the lid 6 times. That didn't fix it.
