I'm sorry to hear you're having these issues with your WF328AAW. First, let's try to determine whether you have the right amount of water filling the washer.

This article includes troubleshooting tips for addressing a low-water level, and running the test "Rinse and Spin" cycle should help to remove any residual suds from the washer, as well.
The odor in your laundry is caused by bacteria that is introduced from the dirty laundry itself as well as from the water supply and other environmental factors, and can get trapped in soap residue on the outside of the drum and in the gaskets and dispenser. Besides the standard maintenance procedures recommended for most front load washers, which include running empty sanitize cycles with bleach, wiping down the gaskets and door between loads, cleaning the soap dispenser and debris filter regularly, and leaving the door open between loads, it is very important to use only the recommended amount of HE detergent.
In addition, the WF328AAW is equipped with SilverCare, an option that can be added to most cycles simply by pressing the SilverCare button at the start of the cycle. SilverCare can be used in any temperature water and is safe for colors and delicates. This feature releases silver ions which are highly effective in eliminating 99.99% of bacteria both from the clothes and from the washer. To treat the odor that has already developed, I would suggest cleaning your washer thoroughly by wiping it down with a bleach solution, then adding SilverCare to your regular laundry routine moving forward, adding it to at least two wash cycles per week.
