What can you determine by observing a load through a washer's glass door?

Observing a load through a washer's glass door provides valuable insights into several aspects of the washing process, and determining the proper load size and mechanical action is one of the most significant observations.

When looking through the glass door, you can assess if the load is appropriately filled—neither too packed nor too sparse. A well-sized load allows for proper agitation, ensuring that clothes can move freely and come into contact with each other and the detergent, which aids in effective cleaning. If the load is too large, it may restrict movement and prevent optimal mechanical action, while a load that is too small may result in poor distribution of cleaning agents and increased wear on garments.

While it may be possible to observe other factors indirectly, such as the effect of water temperature through the level of froth created or even some signs of mold if present—these aspects are less directly observable through the glass door compared to the load size and the way the washer is functioning during the cycle. Therefore, the most definitive observation that can be made when looking through the glass door focuses on the interaction of load size and the mechanical action of the washer.
