Perused appliance parts pros website and videos to diagnose the symptoms, not draining and not agitating.
The videos showed the likely cause. (Drive coupler) And disassembly instructions.
Looked , and was very easy.
Verified the problem.
Ordered parts. I decided to replace the water pump also since it was part of disassembly.
Parts arrived. Installed them and the machine works fine now. For a little more than 100$, which would have not even covered a service call to a rural area.
Happy.
