My LG front loader is only about a month old but I have been reading all the horror stories on various web sites. Obviously, I want to prevent this problem.
After doing all my wash in one day, I am drying out the gasket, taking out and drying the dispenser, and draining out though the little hose every week. Every month I am using the Tub Clean cycle with an ounce of bleach. I have purchased and plan to use every 4 months the Tide product designed for cleaning front loaders. I have read that a product called Whirlrout also works very well but may be harder to find. It is designed for whirlpool tubs.
I hope this maintenance schedule works for me and there may be some help for you. Posters in other web sites swear by it. ... View related article.
