Regular cleaning and maintenance of your dishwasher ensure optimal performance and longevity. Begin by cleaning the filter, as food particles and debris can clog it, reducing efficiency. Wipe down the door edges and seals to prevent buildup of grime and mold. Run an empty cycle with vinegar or a dishwasher cleaner every 1–3 months to clear mineral deposits and sanitize the interior. Check spray arms for blockages and ensure they are working properly. Use the appropriate detergent, and don’t overload the dishwasher, as this can prevent proper cleaning. Lastly, inspect the hose for leaks or damage to avoid water drainage issues.
