Clog in the arm. It should spin due to water flow.
Remove the arm. Usually a tow part arm (top and bottom). Or a central screw with cover plate.
Look for a clog and remove.
If a central arm in the middle of the machine the clog can be in the pipe supplying the water. Again take apart and look for a clog.
They are not belt or gear driven. Simple water driven parts only. If the water is flowing and not leaking under the machine you should be OK with a simple clog somewhere.
