Foam visible in the tank or leaking from the door, with poor washing performance.

Safety first: Turn off the machine if foam threatens to overflow. Avoid mixing chemicals.

• Verify detergent type: Ensure only low-foam commercial dishwasher detergent approved by Meiko is used. Replace any unsuitable product.
• Reduce dosing: Decrease detergent and rinse aid dosing settings gradually until foaming stops while maintaining cleaning performance.
• Rinse contaminated items: Pre-rinse dishes to remove hand soap or other foaming agents before loading.
• Flush the tank: Drain the machine and refill with fresh water to remove excess foam and chemicals.
