Hobart dishwasher displays E8; rinse pump does not operate or final rinse is weak.

Safety first: Disconnect power and close water supply before servicing the rinse system.

• Check rinse supply: Ensure the external rinse supply (if used) is open and that the rinse line is not kinked or pinched.
• Bleed air from system: Some Hobart models require priming of the rinse pump after service. Follow the manual to run a priming cycle or manually bleed air from the rinse line connections.
• Inspect rinse pump: Access the rinse pump assembly. Look for leaks, cracked housings, or loose electrical connectors. Remove any debris from the pump inlet.
• Test operation: Restore power and run a rinse cycle. If the pump does not run or is very noisy, the motor or impeller may be damaged.
• Replace pump if defective: A failed rinse pump motor or impeller typically requires replacement of the complete rinse pump assembly by a qualified technician.
