Past

Everything works, because it spins.

The Agitator is connected to the central spinning body which is powered by the Motor and deactivated by the Off-Balance Switch. 

Time is important.

Water is controlled by the level. 

The power to select transforms into the spinning power. 

Supply must equal drain, which means the pump is a crucial detail. 

The goal of all this is to make a whirlpool.

Future

The goal of the machine is to make a whirlpool. 

Water is required, but does it need to be controlled so much?

The energy that pumps, spins, drains - is it not a waste?

Time is important. 

Does it have to be contained in a tub? 

What happens, when we decide to spin, when we dive into this action without the selector or the off-balance switch?

We save a lot of energy.

So we need a body of water for this to work, which is self-contained naturally. 

Then, add the power.
