How To Clean A Dishwasher?
QUICK ANSWER
Clean a dishwasher by removing and rinsing the bottom filter under running water, then running an empty hot cycle with a cup of white vinegar in a bowl on the top rack. Follow with a short cycle sprinkling baking soda across the bottom. Repeat monthly to prevent buildup and odors.
Dishwashers accumulate food particles, grease, soap residue, and mineral deposits over time, even though they spend most of their working life full of soap and hot water. The result is dishes that come out less clean than they should and a musty smell when the door is opened. Cleaning is straightforward and uses cheap household products. Here is the method and how often to do it.
Why does a dishwasher need cleaning?
Food particles, grease, and soap scum build up in places water cannot flush out: the filter at the bottom, the drain, the spray arms, and the door gasket. Hard water adds mineral deposits to all of these surfaces. Over months, the buildup reduces cleaning performance (dishes come out streaked or with food stuck on), creates odors, and can eventually clog the drain or filter so water does not drain between cycles. A monthly cleaning prevents all of this with about 20 minutes of work.
What is the basic cleaning method?
Whirlpool recommends running an empty cycle with a dishwasher cleaner like Affresh, placed in the bottom of the empty dishwasher. For a DIY approach, fill a microwave-safe bowl with 1 cup of white vinegar and place it on the top rack of an empty dishwasher. Run a normal hot cycle. After the cycle finishes, sprinkle 1 cup of baking soda across the bottom of the dishwasher and run a short hot rinse cycle. Wipe the door, gasket, and edges with a microfiber cloth.
How do you clean the dishwasher drain and filter?
The filter is the cylindrical assembly at the bottom center of the dishwasher tub. Twist counterclockwise to remove and lift out. Rinse under running water and scrub with an old toothbrush to remove trapped food particles. For tough buildup, soak in hot soapy water for 10 minutes. The drain itself is the opening under the filter; remove any visible debris with paper towels or a small grabber tool. For drain clogs causing water to pool at the bottom, mix baking soda and vinegar and pour down before running a hot cycle.
How often should you clean a dishwasher?
Monthly for the full cleaning routine (filter rinse, vinegar cycle, baking soda rinse). Weekly maintenance: rinse the filter under running water and wipe down the door gasket. After every load: check the drain for any food debris. The filter is the single most important maintenance task; a clogged filter is the most common reason dishes come out dirty. Pull it out and check it during weekly maintenance even if you have to skip the full clean some months.
Dishwasher cleaning prevents the musty smell and poor cleaning that comes with neglected machines. Monthly: remove the filter and rinse, run an empty hot cycle with vinegar, finish with a baking soda rinse. Weekly: rinse the filter and wipe the gasket. The filter is the highest-leverage part to maintain. A clean dishwasher cleans dishes better and lasts years longer than a neglected one.
