Hi my slow cooker will not work whenever we try to turn it on the screen says EAA

I had the same problem and I had to ask my wife. You must first select the cook time (button on left). The more time you select, the higher the mode (warm, medium, high). Then you turn the unit on. I guess the unit calculates which mode based on the amount of time you select in step one.

Not nearly as intuitive as it should be.
