Why do front-loading washing machines have that thick rubber ring around the door?
That rubber gasket isn't just there to stop water from leaking. Its flexible design allows it to maintain a seal while the washing machine operates, even as the drum rotates and vibrates.
In this episode, we'll explore why the seal is made from rubber, why it has folds, how it keeps water inside, how it handles movement, why it can collect water and debris, and why it can eventually develop unpleasant odors.
We'll also uncover the purpose of those small drainage holes that are easy to overlook.
A simple rubber ring turns out to be an important piece of mechanical engineering hiding inside an everyday appliance.
