Jenn-Air JDB9200CWS 24 in TriFecta Dishwasher with 44 dBA, Steam Clean, and WiFi Connectivity MECH-07 Error Fix: Musty or Bad Odor

Error code MECH-07 on the Jenn-Air JDB9200CWS 24 in TriFecta Dishwasher with 44 dBA, Steam Clean, and WiFi Connectivity means: Musty or Bad Odor. The dishwasher interior smells musty, like mildew, or has a sour/rotten food odor — food debris trapped in the filter basket, sump area, and spray arm ports decomposes and produces odor; clean the fine mesh filter and the entire sump area; remove and clean both spray arms; run an empty hot cycle with a commercial dishwasher cleaner or with a cup of white vinegar placed upright in the upper rack; leave the door slightly ajar between uses to allow air circulation and drying, which prevents mold and mildew growth
