LG Electronics — Washer rusting

We purchased our top load LG washer less than three years ago. It is now rusting near the detergent dispenser. Looking online this is a known issue but LG claims rust is associated with spilled bleach. We have never used bleach in our machine. I was advised by LG customer service that I would be responsible to "fix it myself". This means purchasing a new unit. I am very dissatisfied with the product, customer service and their suggested "resolution".
