Chemical smell or visible chemical residue on dishes after washing.

Safety first: Use appropriate PPE when handling chemicals and adjusting pumps.

Reducing chemical residue:

• Adjust dosing pumps: Reduce the Champion detergent and rinse aid pump settings incrementally and observe results.
• Verify chemical type: Ensure chemicals are approved for use in high-temperature commercial dishwashers.
• Check final rinse flow: Confirm that the final rinse spray pattern is full and even, and that the rinse solenoid opens for the correct duration.
• Rinse affected items: Manually re-rinse any items with heavy residue before reuse.

When to call a technician: If pump controls or external chemical controllers do not respond to adjustments, professional calibration or replacement may be needed.
