For optimal cleaning results, follow these tips when you load your dishwasher. Scrape leftover food bits off before you load. Load crockery upside down so the water can easily drip off. Try not to overcrowd your dishwasher because the water and detergent need room to move around for best cleaning results. Stack plates and bowls facing the inside, and make sure they don’t overlap, blocking water access. Check that the spray arms aren’t being blocked by larger items and can move normally. Finally, clean the filter every week and the rubber seals every month, and you’ll be able to enjoy squeaky-clean dishes every time!
