In most cases, it is generally recommended to rinse off any large food particles or debris from your dishes before placing them in the dishwasher. However, whether you need to thoroughly wash them with soap and water depends on the dishwasher and your personal preference.
Modern dishwashers are designed to handle food remnants and can effectively clean dishes that have been lightly rinsed. However, heavily soiled dishes with dried-on food may not come out completely clean if they are not pre-rinsed or pre-washed.
Pre-rinsing or lightly washing your dishes can help improve the overall performance of the dishwasher and prevent clogs caused by food particles. It also helps ensure that your dishes come out as clean as possible. Additionally, some dishwasher manufacturers may require pre-rinsing to maintain the warranty.
Ultimately, it's best to consult the specific instructions and guidelines provided by your dishwasher manufacturer for the most accurate information regarding pre-washing or rinsing dishes.
