Using regular dishwashing liquid or detergent meant for handwashing dishes in a dishwasher can have several consequences and should be avoided. Here are some of the potential issues:
Excessive Foaming: Dishwashing liquids are designed to create a lot of foam when agitated, such as when washing dishes by hand. When used in a dishwasher, they can cause excessive sudsing, leading to overflow and leaks. The dishwasher may not be able to handle the excess foam, leading to water spilling out of the dishwasher door or causing damage to the machine.
Inefficient Cleaning: Dishwashing liquids are not formulated for use in dishwashers, which means they may not be as effective in cleaning dishes when compared to dishwasher-specific detergents. The lack of proper enzymes and surfactants designed for dishwasher use can result in residue and food particles left on dishes.
Potential Damage to the Dishwasher: The excess foaming caused by using regular dishwashing liquid can lead to clogs in the dishwasher's drain and filter systems. Additionally, the soap may leave a film on the dishwasher's interior and components, affecting its performance and longevity.
Voiding Warranty: Most dishwasher manufacturers specify the use of specific dishwasher detergents to maintain the warranty. Using inappropriate cleaning agents might void the warranty, leaving you responsible for any repairs or replacements.
Environmental Impact: Dishwashing liquids designed for handwashing dishes might contain chemicals that are harmful to the environment. Dishwasher-specific detergents are generally formulated to be more environmentally friendly and have lower phosphates and other harmful ingredients.
To ensure the best performance and longevity of your dishwasher, always use dishwasher-specific detergents as recommended by the manufacturer. If you run out of dishwasher detergent and have no alternative, it's better to wash the dishes by hand rather than using regular dishwashing liquid in the dishwasher.
