How can I get my washing machine to put more wanted while washing my clothes?

This is what you must do:

Do not call a professional.

Take a deep breath.

Press the button.

Watch and learn.

Adam machines like this go on weight load

So a heavy weight will only require a minimum amount of water

Or it will cause your machine to be overloaded

Trust the machine to do what its meant to

You cannot make it get more water. they are designed to use little water, and prevent you from adding more. ( some if you do mannage to add water they stop, and drain it before they proceed)

The water plus option will add approximately 2 – 4 extra gallons of water to the current selected wash cycle. NOTE: Water added using the "water plus" option will be distributed throughout the entire cycle and does not enter the drum all at one time. (source LG)

In other words it adds less than one gallon to each part of the wash.

That little button is really your only option.

It sounds like you don't have access to the owners manual; otherwise you would have looked it up. If this is the case, go to the manufacturer's website and see if you can find your machine's manual there. Or, better yet, call the manufacturer's customer service line and they will explain what this feature does and how it works. You could just experiment with your machine and see what that button actually does. Good luck!
