The ideal time to add a dirty dish to a dishwasher is before the dishwasher starts its cycle. Once the dishwasher cycle has begun, it's generally not recommended to open the dishwasher and add more dishes. However, the specific rules and features can vary depending on the dishwasher model.
Here are some general guidelines:
Before starting the dishwasher: Make sure to load all your dirty dishes into the dishwasher before starting the cycle. Once the cycle begins, the dishwasher door should remain closed until it completes the cleaning process.
Some dishwashers have a pause feature: Some modern dishwashers have a pause button or a "Add a Dish" feature that allows you to stop the dishwasher temporarily, open the door, and add a forgotten dish. The dishwasher will resume from where it left off when you close the door and restart it.
Check the manual: Always refer to your dishwasher's manual for specific instructions and features. The manual will provide accurate information about whether your dishwasher allows you to add dishes during the cycle and if there are any limitations.
Be cautious with high-temperature cycles: If your dishwasher uses high-temperature cycles such as a sanitize or dry cycle, it's best not to open the dishwasher during those cycles to avoid potential burns or safety hazards.
Risk of water spillage: Opening the dishwasher mid-cycle can cause water to spill out, creating a mess and potentially damaging your kitchen floor.
In general, to ensure the best results and avoid any potential risks, it's recommended to plan ahead and load all dirty dishes into the dishwasher before starting the cycle. If you forget to add an item, you may have to wait until the current cycle is complete before adding it for the next cycle.
