I’ve had success with Jet Dry and Cascade Platinum plus pods. Our filter gets super gross after about 10 cycles. Between cleaning out the filter often and running those two product combos, we don’t really have a smelly washer. My other thought was your water quality. We have a whole house water softener. Have you tested to see if you have super hard water? This ruins appliances. Simple test can be bought on Amazon.
Preach.
