Hi, I have a top loading panasonic washing machine.

It is an no agitator top loading machine - something similar like this type - http://www.automaticwasher.info/TD/AWJPEG/MODERN/2011/freewestinghous++11-19-2011-03-25-8.jpg.

So now i dont know if i have a damaged bolt, or a missing washer or a missing nut or a damaged washer.

Let me explain the problem.

This problem exists from quite a long time.

The spinning motor suddenly loses contact with the screw.
The bolt/screw and the base plate then do not spin, whilst the motor spins inside.

I have added all pictures of my washing machine components.

To summarize the problem, whilst the motor is spinning, the bolt becomes lose during operation and it loses it contact and it does not spin anymore, and i keep tightening it with screw driver every few minutes to fix the problem until it occurs again.

All pictures can be found here.

If the problem still remains unclear let me know, i can try to record another video

I wanted to know how can i fix this problem, should i buy a new bolt (bigger??), new nut??, new washer??
