I 2018 udgav det tyske magasin Stiftung Warentest en rapport om reparation og levetid for opvaskemaskiner.

I undersøgelsen har Stiftung Warentest kontaktet flere store producenter for at få oplysninger om den forventede levetid på deres opvaskemaskiner. Miele oplyser, at deres opvaskemaskiner har en forventet levetid på 20 år, hvilket er den længste blandt producenterne. De fleste andre producenter, herunder Gorenje, Bosch, Neff, Siemens m.fl., angiver en forventet levetid på mindst 10 år.

• Regular cleaning: Remove food debris and rinse the dishwasher’s filter and spray arms regularly to prevent clogging and ensure effective dishwashing.
• Clean seals and doors: Keep the seals and door clean to prevent mould and bacteria formation as this can affect the machine’s performance.
• Avoid using too much detergent: Use only the amount of detergent specified in the manufacturer’s instructions. Using too much detergent can lead to foaming and damage the machine.
• Maintenance of salt and rinse aid containers: Keep the salt and rinse aid containers filled according to the manufacturer’s instructions to ensure that your dishwasher operates optimally and extends the lifespan of your dishes.

• Quality and brand: The quality of the dishwasher and the manufacturer’s reputation play a significant role. A higher-quality machine from a reliable manufacturer tends to have a longer lifespan than a cheaper model of lower quality.
• Usage pattern: The frequency of use and the type of dishes typically washed in the machine can affect the lifespan. Running many loads of dishes will wear out the dishwasher faster.
• Maintenance: Regular maintenance is crucial to extending the lifespan of a dishwasher. Cleaning the filter, cleaning seals, maintaining salt and rinse aid containers, and preventing limescale build-up are all important maintenance tasks.
• Water quality: The hardness and quality of water can affect the dishwasher’s lifespan. Hard water with high mineral levels can cause limescale build-up and damage the machine over time.
• Adherence to the user manual: Follow the manufacturer’s instructions for the use, maintenance, and cleaning of the dishwasher to ensure optimal performance and lifespan.
