Was doing some soaking in my orbital Maytags last night when I noticed one wasn't making the telltail splish-splash noise. It wasn't agitating at all and the agitator seemed awfully tall. So I put the half clothespin into the lid switch, pushed down on the agitator, it engages for 4-5 strokes, popped up and disengaged again. Cancelled thie cycle, drained/spun out the load. I thought the nut had come loose one the shaft, but when I lifted the agitator, the entire shaft came out! Has anyone seen this before? Is there a lock nut at the other end of the shaft?
