Is it Safe to Wash Dishes in the Dishwasher During a “Boil Water” Advisory?

When a “boil water” advisory is issued, it’s natural to question the safety of using household appliances that utilize tap water, such as dishwashers. The concern is valid, as the advisory typically means that the water supply may be contaminated with bacteria or other harmful microorganisms. This article aims to answer the question: “Is it safe to wash dishes in the dishwasher during a ‘boil water’ advisory?”

Understanding a “Boil Water” Advisory

A “boil water” advisory is a public health measure that is issued when there’s a risk of the water supply being contaminated. This could be due to a variety of reasons such as a water main break, natural disasters, or a problem at the water treatment plant. The advisory instructs residents to boil their tap water before using it for drinking, cooking, brushing teeth, and washing dishes.

Using a Dishwasher During a “Boil Water” Advisory

Most modern dishwashers have a sanitizing cycle that heats water to a temperature high enough (at least 150°F or 66°C) to kill most types of bacteria. If your dishwasher has this feature, it should be safe to use during a “boil water” advisory. However, if your dishwasher doesn’t have a sanitizing cycle, or if you’re unsure, it’s best to err on the side of caution and hand wash your dishes.

Hand Washing Dishes During a “Boil Water” Advisory

If you choose to hand wash your dishes, you should first wash them with soap and hot tap water, then immerse them in boiled water for at least one minute to ensure any remaining bacteria are killed. Remember to let the dishes cool before handling them to avoid burns.

Additional Precautions

During a “boil water” advisory, it’s also important to consider other ways you use tap water. For example, you should use boiled or bottled water for brushing your teeth, making ice, and preparing food. Also, remember to discard any ice made by your refrigerator’s ice maker during the advisory period.

Conclusion

In conclusion, while it may be safe to use a dishwasher with a sanitizing cycle during a “boil water” advisory, it’s always best to take extra precautions. Hand washing dishes with boiled water or using disposable dishes and utensils can provide peace of mind during these advisories. Always follow the guidance of your local health department or water utility, as they have the most accurate information about the safety of your water supply.
