Recently I purchased serial# TH93318999/model# FFCD2413UB2A on 11-24-2019. I did not purchase the protection plan. In December, the dishwasher stopped using detergent and it remained in the opened dispenser. Also, plastic pieces around the rack to support the dishes have melted away and the metal is exposed and rusting. I used the recommended detergent; Cascade and Cascade Rinse Aid. I did not expect this from an appliance that's about a year old. This product was purchased at Lowe's, 7420 Garners Ferry Road, Columbia, SC 29209.
