Detergent sheets and HE top loader

I just bought a new LG HE top loading washer and am struggling to get used to it. I have been using EarthBreeze detergent sheets successfully in my old washer, but they don’t seem to dissolve in the minimal amount of water in the new HE washer. I tried tearing them up into small pieces and putting them in the liquid detergent dispenser, only to find a tray of undissolved goo in there after the wash cycle was completed and the rinse cycle had begun. Anyone have any tips about using detergent sheets or can recommend me a great unscented liquid detergent? Honestly, this HE washer is a mystery to me. I wouldn’t be surprised if it takes off and flies to the moon!
