I had a friend who bought the first-gen Maytag Neptune front loader in 1997 and he had problems with mildew (those machines had a 60% fail rate overall).
We had a Whirlpool front loader (2008-2021) and LG front loader (2021-2023 when we moved) and never had this problem with either one. I think you can avoid it if you are fastidious about doing the following:
- Run the cleaning cycle every month. Add it to your calendar as a task so you remember to do it! Both the Whirlpool and LG machines had a dedicated Clean Cycle in which you add 1/2 cup of bleach and the machine uses a high water level to sanitize the drum.
- After the cleaning cycle, use a clean dry towel to thoroughly wipe out and dry the deep gasket around the opening. The cleaning cycle does a good job of removing most of what collects on it, but a quick wipe finishes the job. Also, wipe the gasket on the inside of door itself, the door glass, and the metal surround around the door opening.
- When not in use, leave the detergent drawer and the door open! No one likes to do this, but this allows the machine to dry out and is probably one of the most important things you can do to prevent mildew.
- Occasionally clean the detergent drawer. Take it out, take it apart, rinse under warm water, dry it, reassemble and reinstall.
Loved the LG WM3900HWA washer and DLEX3900W dryer. Wish I still had them!
