Help!

All of a sudden, my washing machine is flatly refusing to do the final spin cycle ... it was fine yesterday.

There *may* be a correlation ... yesterday I did a heavy duty load with our Stampede clothes, and when I pulled out the stuff, there were some small rocks and bits of grass that had snuck in, and there was a fair bit of dried mud residue in the laundry trough ...

So possibly, I did the wash, it washed fine, but mud has since caked up on the inside ... oops ...

We've tried different things (pulling out some clothes, emptying it altogether, feeling around for anything blocking the little holes - no bone.

How do I fix it?
