Overview

This video discusses why modern dishwashers often don't wash dishes effectively, attributing the problem to a focus on energy efficiency over cleaning performance, particularly in the European market. The speaker explains how reduced water and energy consumption, longer cycle times, and less aggressive detergents compromise washing quality. They also offer practical advice for users to improve their dishwasher's performance and suggest ways to verify actual performance.

Key takeaways

• Energy Efficiency vs. Cleaning Performance: The primary reason for poor washing results in modern dishwashers is the prioritization of energy and water efficiency, mandated by European standards, over effective cleaning.
• Compromises Made by Manufacturers: To meet energy efficiency targets, manufacturers reduce water volume, which necessitates longer wash cycles and less aggressive cleaning agents. This results in dishes not being properly cleaned.
• Impact of Reduced Water and Temperature: Lower water volume and potentially lower actual washing temperatures (despite advertised settings) lead to dried-on food and bacteria not being effectively removed, resulting in unclean and potentially unsanitary dishes.
• Detergent Limitations: Modern detergents are less aggressive than older formulas, lacking components for effective antibacterial treatment or stain removal, further contributing to poor cleaning results.
• Solutions for Users:
  • Pre-wash/Scrape Dishes: While not ideal, users may need to pre-rinse or scrape dishes before loading.
  • Connect to Hot Water: Connecting the dishwasher to a hot water supply can help compensate for reduced heating efficiency and lower water pressure.
  • Monitor Actual Temperature: Using a Bluetooth thermometer probe can help determine the actual washing temperature achieved by the machine, allowing users to select programs that offer a better balance of safety and cleaning.
  • Rethink Energy Efficiency Ratings: The speaker advises viewers to disregard energy efficiency ratings, as they often mislead consumers into purchasing appliances that perform poorly and may even cost more in the long run due to inefficient cleaning and potential health risks.

Users can take the following practical steps to potentially improve their dishwasher's cleaning performance:

• Connect to Hot Water: Hooking up the dishwasher to a hot water supply can help compensate for the machine's reduced ability to heat water efficiently and can also address issues with low water pressure.
• Monitor Actual Washing Temperature: Using a Bluetooth thermometer probe (like one for an oven) placed inside the dishwasher can help users determine the real temperature achieved during a cycle. This allows them to select programs that offer a better balance between safety and effective cleaning.
• Pre-rinse or Scrape Dishes: While not ideal, the speaker suggests that users might need to pre-rinse or scrape dishes before loading them, especially if they can't run the dishwasher immediately after a meal.
• Adjust Settings: Users can look into the settings for water contamination control systems, as these can sometimes lead the machine to wash at lower pressures and temperatures, compromising cleaning.
