A dishwasher – a key kitchen appliance – is constantly exposed to water, acidic food scraps, and abrasive cleaners which can lead to corrosion and breakdown of parts and liners which without regular maintenance, can lead to appliance failure.
The average lifespan of a dishwasher is 9-16 years, with a median longevity of 12 years. There are signs of when a dishwasher needs maintenance or to be replaced, including dishes remaining dirty after washing, dishes not drying when a drying cycle is selected, a water leak, and control panel failure. Steps to take to extend the life of the kitchen appliance include scraping dishes of debris prior to loading, following the manufacturer’s loading suggestions, cleaning filters, air-drying dishes, and making sure water used in cleaning is very hot.
