Strong chemical odor or visible chemical residue inside the tank or on dishes.

Safety first: Wear chemical-resistant gloves and eye protection. Ensure good ventilation.

• Review chemical settings: Access the Insinger or third-party chemical controller and verify detergent and rinse aid pump run times are within recommended ranges.
• Confirm correct products: Ensure that only Insinger-approved or compatible commercial dishwashing chemicals are used at the proper dilution.
• Inspect chemical pumps: Check that pumps stop when commanded. Replace any pump or relay that continues to run after the dosing period.
• Flush the system: Run several rinse-only cycles to dilute and remove excess chemicals from the tank and lines.
