In mechanical dishwashers, what is the first step in the cleaning process?

The first step in the cleaning process of mechanical dishwashers is indeed the prewash. This step is crucial as it involves the initial rinsing of the dishes to remove loose food particles, grease, and debris before the actual washing cycle begins.

During the prewash phase, water is sprayed onto the dishes, which helps to prepare them for the more intensive cleaning that follows in the wash cycle. This step is essential for ensuring that the wash cycle is effective, as it prevents large food particles from clogging the dishwasher’s spray arms and filters during the main washing phase.

Without this preliminary step, food residues might not be adequately removed, leading to less effective cleaning. Consequently, the prewash sets the stage for optimizing the performance of the dishwasher during the wash phase and enhances the overall cleanliness of the dishes.
