Just as an fyi--- the new whirlpools have a senor that only test the loads before it starts. So---if you lift the lid it will default to "extra large" load. This is a feature that will enable it to save water. With all HE model (this is very close to one) there should be a "lock" feature however this does not because consumers wanted the option to "open the tub when wanted". So, it is not something wrong with the item, it is just a completely different way of using them. Just as an FYI--- fill it, close it and watch it work wonders.
