Hobart dishwasher displays E18; rack transport or conveyor movement fault on rack-conveyor models.

Safety first: Disconnect power before working near moving parts. Do not reach into the conveyor tunnel while the machine is energized.

• Clear rack jams: Inspect the conveyor path for racks stuck against guides, bent racks, or foreign objects. Remove obstructions.
• Check chain/belt: Access the conveyor drive area. Look for broken, loose, or derailed chains/belts. Re-seat or replace as needed.
• Inspect motor and gearbox: Check for oil leaks, unusual noise, or overheating. A seized gearbox or motor will prevent movement.
• Verify sensors: Locate conveyor limit switches or proximity sensors that detect rack position. Ensure they are clean, aligned, and securely mounted.
• Professional repair: Conveyor drive repairs often require alignment and tensioning; if E18 persists, contact a Hobart technician.
