This is a critical issue for both high-efficiency front-load and top-load machines. Always use the minimum amount of HE detergent (1-2 tsp per load). Because these machines use less water, regular detergent produces an excess amount of suds and allows film build-up on the drum and hoses that can damage. It may even void the manufacturer’s warranty. If you use single-use pods, make sure to place them in the bottom of the drum (never in the dispenser) before adding clothing to allow the longest amount of time in the water.
