4. Operating Instructions

Follow these steps for optimal use of Finish Hard Water Booster Powder:

1. Load Dishwasher: Load your dishwasher as usual, ensuring dishes are arranged to allow water circulation.
2. Add Booster: Fill the pre-wash chamber of your dishwasher with Finish Hard Water Booster Powder. If your dishwasher has only one detergent chamber, dispense approximately 2 tablespoons of the booster powder directly into the bottom of the dishwasher tub before starting the cycle.

5. Maintenance

Regular use of Finish Hard Water Booster Powder helps maintain your dishwasher by preventing mineral buildup. No additional maintenance steps are required for the product itself.

6. Troubleshooting

If you experience issues with dish cleanliness or hard water spots after using the booster, consider the following:

• Insufficient Dosage: Ensure you are using the recommended amount of booster powder. For very hard water, you may need to slightly increase the amount within the recommended guidelines.
• Dishwasher Loading: Verify that your dishwasher is not overloaded and that dishes are not blocking spray arms, which can prevent proper water and detergent distribution.
• Detergent Compatibility: While designed to work with most detergents, ensure your primary dishwasher detergent is suitable for your water type.
• Dishwasher Condition: Periodically clean your dishwasher's filter and spray arms to ensure optimal performance.
