Jenn-Air JDTSS244GP 24 in Top Control Built-In Dishwasher with 42 dBA, Third Rack, and Sensor Wash MECH-05 Error Fix: Rust on Dish Rack Tines

Error code MECH-05 on the Jenn-Air JDTSS244GP 24 in Top Control Built-In Dishwasher with 42 dBA, Third Rack, and Sensor Wash means: Rust on Dish Rack Tines. The vinyl coating on the dish rack tines (wire prongs) has chipped or worn through, exposing the steel wire underneath to water and detergent — the exposed steel rusts, staining dishes and continuing to corrode; for small areas of damage, use a vinyl tine repair kit (small rubber or vinyl caps that press onto damaged tines); replace the entire rack if rust is extensive or if many tines are damaged; rust is more common on tines near the edges of the rack where dishes frequently contact them
