The article delves into a common debate regarding the cost-effectiveness of using a dishwasher compared to hand washing dishes. It argues that while many may perceive hand washing as cheaper since it does not consume electricity directly, the comparison must include factors such as water usage and the energy costs associated with heating the water. The analysis presents detailed figures for the average water and electricity consumption of modern dishwashers, demonstrating that their operational costs can be quite reasonable.

Specifically, it outlines that a modern energy-efficient dishwasher utilizes approximately 9–12 liters of water and 1–1.5 kWh of electricity per wash cycle. With the average electricity cost in Greece hovering around €0.23 per kWh, running a full cycle in a dishwasher comes to about €0.35 to €0.45. If operated five times a week, this translates to an estimated monthly expenditure of €8–€9, which is presented as a feasible option for regular dishwashing needs.

On the other hand, hand washing dishes entails using significantly more water—up to 60 liters over a span of 10 to 15 minutes—along with the necessary energy for heating that water, especially if done using an electric heater. The article concludes that after considering all variables, including time and resource consumption, using a dishwasher might not be as costly as commonly assumed, challenging the prevalent perception that hand washing is the more economical choice. This analysis has implications for household budgeting and encourages a reevaluation of common kitchen practices.
