Why do some clothes washers drain all water before spin cycle, and some don't bother?

Question

Some top loading clothes washers drain all the water before the spin cycle starts and others just start spinning with a full tub of water..

It would seem to me that not draining all the water before the tub starts spinning would produce more effective water extraction from the clothes

Answer 1

In this case, it doesn't really matter. Water will be pushed out due to the gyration of the machine. Some drain as much water out as possible before going into the spin cycle, some don't. There really is no difference to be honest. Not draining until it starts spinning will extract just as well as draining beforehand. The more RPMs the unit has, the more water will be forced out. As far as energy consumption is concerned, draining before spinning would make the unit more energy efficient because water is heavy. Clothes in the same amount of water makes it heavier, which means the machine would require more electricity to get the inertia moving and to stay moving. So if you drain out as much water as possible before spinning, there is less weight, which means less energy it takes to spin. Newer EnergyStar top loaders drain then spin because of this reason.

I hope I helped you!

Answer 2

I disagree. If there is no water it is easier to spin out the clothes. I'd think that one work correctly and the other doesn't

Answer 3

some use centrifical force to help the draining process in order to save time.

Answer 4

I think front loaders are the answer....use less water, detergent, and energy...(they also get the clothes cleaner and no pills on anything....)

Answer 5

more expensive dryers drain water first, less wear and tear on bearings belts pulleys, etc.

Answer 6

That is the way they are designed.
