Two tricks to avoid smell in front loader. Both needs to be followed when washer is brand new. Getting rid of the established mold from humid place is very hard.
1. Look at back of the washer and locate some grill area towards top of the washer. Install a small computer fan that can run off 5v USB charger. Air flow should be away from the washer. Keep this fan running 24-7 and keep the washer door closed. The trick is keep the humid air out of the drum area. This is the most important step.
2. Clean the "penny catcher" couple of times a year. Not that important. We clean this every year.
We have yet to see any mold signs or smell in my washer in 5 years. My last front loader without these preemptive measures started smelling in 3 years.
