The only instance I've used pods was a frontloader (a Kenmore-badged LG) at a friend's place in Sept 2023 when there for his son's wedding. I ran three loads of this-and-that. I had noticed that the bath linens had a moderate musty odor. I loaded in what was in the guest bathroom, accumulated in the laundry room, and a few more clean items in the nearby linen closet. Upwards of fist-space-at-the-top size of load. Kirkland/Costco pods of some variety. Tossed in two, directly into the drum, not the dispenser drawer. Paused when fill was complete, water not slippery. Added another. Note that the fill level was quite low, enough to saturate the items dripping-wet and a small puddle in the drum when paused. The other loads were somewhat smaller so two pods on them.
The bath linens came out with noticeably less odor.
