Error code MECH-01 on the Jenn-Air JDB9200CWS 24 in TriFecta Dishwasher with 44 dBA, Steam Clean, and WiFi Connectivity means: Upper Spray Arm Not Spinning. The upper spray arm is clogged with food debris or mineral deposits and is not rotating freely — remove the upper spray arm (it usually twists off counter-clockwise or has a locking nut), clean all spray jets with a toothpick or small wire, and flush the arm with running water; check the water supply tube to the upper arm for blockages; also check the spray arm bearing/bushing for wear — a wobbly arm with a worn bearing does not spin properly and produces poor cleaning on the upper rack
