Somehow Rust Built Up in My LG Washer

I bought my LG washer 1.5 years ago, and now it's rusting! I bought a Siemens washer in 2009 and had it for 13 years without any rust or motor problems. When I called for help with a problem with the shock absorbers, they told me that if I got new shocks, I could go another 10 years without any problems. In order to get something better, we chose LG. After using it for a year and a half, it started to rust. MTV Electronics authorized service was contacted, photos were sent, and it was declared out of warranty. led me to the 444 call center, which then sent me to WhatsApp without solving the problem. Even though the expert was helpful on-site, when he called, he said rust wasn't covered and wanted 2,500 TL to replace the part. Not acceptable! During the warranty period, rust that hasn't been damaged or scratched is not okay. I want to get a new appliance within the warranty period
