Washer works fine, but gets stuck on the final spin.

Fills with water, washes, spins, drains, fills for rinse, rinses, spins, everything normal - but doesn't stop spinning when timer gets to "off".

I replaced the timer mechanism just last year.

This happens in any of the three cycles (normal, permanent press, gentle). All work perfectly until the final spin - when the cycle gets stuck.

Doesn't seem the mechanical timer would get stuck only at final spin, in three different cycles.

Can you suggest what I need to repair?
Thanks.
