Error code MECH-02 on the Jenn-Air JDB9200CWS 24 in TriFecta Dishwasher with 44 dBA, Steam Clean, and WiFi Connectivity means: Lower Spray Arm Clogged. The lower (main) spray arm jets are clogged with food particles, calcium/mineral deposits, or small debris — the lower arm handles the majority of the cleaning; remove the arm (typically lifts off or unscrews from the center hub), clean all jets thoroughly, and check the center bearing for wear; a spray arm that wobbles on its hub has a worn bearing and should be replaced; after cleaning, spin the arm by hand to verify it rotates freely
