Using an HE (High Efficiency) washer is different than the previous generation of washers. You can't just shove dirty clothes in a big wad. You have to use a light hand and run a smaller load of clothes. I used to get stuck in the appliance dept at Home Depot. I learned a lot about HE washers because so many people had problems with them. Turned out they just needed to adjust how they loaded the machine. Kinda like going from a 700W microwave to a 1000W microwave. There will be some adjustments that need to be learned. HE washers just work better with liquid detergents. So do HE dishwashers and the small countertop dishwashers.
I have a Whirlpool Cabrio TOP LOAD HE washer. I find that I need to put clothes in the bottom of of the tub in a single clump, one item at a time. I start out spacing the clumped items, 6 items in the first layer, evenly around the tub. Then I put a second layer, lightly laid on top of the first layer but off set between the first layer clumps. With shirts, I can run a 3rd layer. I add a Color Catcher sheet and about a cup of baking powder on top of the dry clothes. I buy baking soda in 15 pound bags from Sam's Club.
I use 2 TBSP of a low sudsing coconut oil based liquid dish detergent. The brand I use is the PINK dish detergent from Sam's Club. I use white vinegar in the fabric softener dispenser. I don't use fabric softener in the washer or dryer. I have allergies to many of the fragrances used in laundry detergents.
I run most loads on Normal wash/Heavy soil/High spin/cold wash-cold rinse/Deep clean cycle. My daughter works at Harbor Freight and her work clothes are full of dirty mineral oil. They do come out clean. I don't pretreat her clothes either.
Bedding, coats and towels (I have bath sheets which are heavy oversized towels) are washed on Bulky Wash with all the other settings the same. Bulky Wash uses a higher level of water. But it's still not like the non-HE washers.
I used the same settings and methods when I was using my other daughter's front load HE washer. I also wiped out the door gasket with every use since we had dog hair in the laundry loads.
