You couldn't do that with mine. Mine locks the lid while it's filling. I guess there's probably a way around it, like that old washer I had when growing up. It would fill up with the lid open, but wouldn't run when filled unless the lid was closed. It had a plastic tip on the lid that shoved a metal lever down. I used to stick something in the hole to press the lever down, so it would run with the lid open and I would watch it. The suds and the agitator spinning and flipping the clothes around in the large tub filled with water fascinated me. Now they're push button and LED instead of that knob you spun into the right position and it made a horrible grinding noise while turning it, then you pulled it out to start it.
I've been reading some on it, and apparently you're supposed to put the pod in first, and then put in the laundry. Supposedly being on the bottom helps the agitatator break it open. Even a top loader without the without a shaft agitator should easily break it open. But as I said about front loaders, if the cycle is rough enough to clean the clothes, it should be rough enough to break it open.
This kinda makes me wanna take a couple plastic cup with cold, room temp, and hot and drop the pods in and see the dissolve speed. Guess I could use something to swish it around to see it break up but I only got 2 hands lol
