How to get GE Lo-Water PreciseFill unstuck from rinse mode?
It turned out to be a bad timer. Since it drained, and spun and rinsed, I knew it was not the pump or filter or motor. I found "the last one" online, but it was a super easy fix that saved my hundreds of dollars (thousands if my girlfriend had her way). Just locate your model number (on the inside of the lid, or under it on the body). 

Just pop the top control panel off by removing three screws. Then unscrew the circuit board. The handles just pull off with evenly applied pressure.
