Which? has tested the efficiency and cost effectiveness of three common dishwasher cycles, revealing that the eco setting can save households nearly £19 per year compared to the standard programme. With many British families seeking ways to reduce household expenses amid the cost of living crisis, the findings offer a practical tip for cutting energy bills.
The consumer magazine examined the cleaning performance and running costs of the main/auto, eco, and quick wash settings. Contrary to a common misconception, the quick wash cycle was found to be more expensive to run than the main programme, while also being less effective at cleaning and drying dishes.
Which?'s tests showed that the eco mode consumes less energy and water than the standard cycle, though it does not clean or dry quite as well. Cleaning efficiency was 79 per cent for eco versus 83 per cent for the standard programme, and drying efficiency was 76 per cent compared to 82 per cent.
In terms of cost, running five cycles per week on the standard programme amounts to £71.01 annually, while the quick wash costs £73.93. In contrast, exclusive use of the eco cycle would cost just £52.13 per year, saving £18.88. Over five years, the savings total £94.40, with eco costing £260.65 versus £355.05 for the standard programme.
Additionally, Whirlpool specialists advised against pre-rinsing dishes before loading, as this can interfere with sensors in modern dishwashers, potentially leading to less effective cleaning cycles.
