The Dirty Truth About Your Dishwasher
Dishwashers, the trusted appliances we rely on to keep our eating utensils clean, are often hiding a grimy secret. Recent research has uncovered that bacteria levels in some machines can reach alarming heights. In one study, measurements showed levels at 135 on a scale where 250 is considered a full-blown germ fest. This investigation found dishwashers harbour higher germ counts than many other household appliances, raising serious concerns about kitchen hygiene.
Survey Reveals Widespread Neglect
A survey of one thousand people conducted by Domestic & General highlighted just how dirty these everyday appliances can become. Shockingly, one in four Britons admitted they have never cleaned their dishwasher. Experts caution that skipping regular maintenance means families might be washing plates, glasses, and cutlery in a buildup of grease, food waste, and harmful bacteria. Over time, this neglect not only poses health risks but also reduces the appliance's efficiency, leading to potential costly repairs or early replacement.
Expert Insights on Dishwasher Care
Salah Sun, a representative from Beko UK, emphasised the benefits of dishwashers while stressing the importance of upkeep. "There are many advantages to having a dishwasher at home," Sun said. "These appliances can use less water than handwashing while ensuring items are cleaned and sanitised effectively. However, a dishwasher will typically deliver reliable performance for up to a decade if it is properly maintained and cleaned. When neglected, it will not operate as efficiently as it should, increasing the risk of costly repairs or even premature replacement."
Key Areas Where Germs Accumulate
Germs are most likely to build up in three hidden areas inside a dishwasher, which require regular attention to maintain hygiene and functionality.
- The Filter: This component traps food debris to prevent recirculation during wash cycles. Due to its role, it can quickly become clogged if not cleaned regularly. Sun noted that unpleasant smells or food residue on dishes after a cycle can signal a dirty filter. "We recommend cleaning your dishwasher's filter at least once a week," he advised. "Remove it, rinse under warm water, and scrub away debris before refitting securely."
- Spray Arms: These distribute water through small jets, which can get blocked by food particles or limescale, especially in hard water areas. Sun explained that reduced cleaning performance or ineffective washing might indicate blocked spray arms. "Take them out monthly, rinse under warm water, and use a soft cloth or brush to clear nozzles," he suggested, adding that this maintains strong water flow and hygienic results.
- Door Seals: The seals create a watertight barrier but can attract food residue, grease, and moisture in the warm, damp environment. Neglect can lead to bad odours and weakened seals over time. Sun recommended wiping them down with a damp cloth at least once a week to prevent buildup.
Simple Steps for Optimal Performance
To keep dishwashers hygienic and working properly, follow these maintenance tips:
- Scrape food from plates before loading them into the dishwasher.
- Leave the door open after a cycle to allow the appliance to air dry thoroughly.
- Clean the filter and door seals on a weekly basis to prevent residue accumulation.
- Remove and rinse the spray arms once a month to ensure unobstructed water distribution.
Regular maintenance not only helps prevent unpleasant odours but also improves cleaning performance and extends the lifespan of the appliance, according to Beko. By incorporating these habits, households can ensure their dishwashers remain efficient and safe for daily use.
