How to Deep Clean and Maintain Your Dishwasher

DISHWASHERS are workhorses that often get taken for granted until they start leaving behind grit or a damp, musty smell. A clean machine doesn't just look better; it washes your dishes more effectively and extends the lifespan of the pump and heating element. When done well, the interior should gleam, the gaskets should be supple, and the drainage should be silent and swift. Regular maintenance prevents the buildup of hard water minerals and food particles that eventually clog internal components. This isn't a complex chore, but it is one that requires consistency. By spending twenty minutes once a month, you prevent the expensive plumbing issues that occur when a dishwasher stops draining properly or begins to leak.

1. Unlock and Scrub the Filter. Locate the filter assembly at the bottom of the tub. Twist it to unlock it, remove the mesh screen, and scrub it under warm running water with a soft brush to remove trapped food debris.
2. Clear Spray Arm Nozzles. Inspect the holes in the rotating spray arms for clogs caused by mineral deposits or food. Use a piece of wire or a toothpick to clear any blockages found in the nozzles.
3. Banish Mold from the Seal. Pull back the rubber seal around the door frame and wipe out the grime that collects there. Use a damp cloth to clean the edges of the door where it meets the machine, as this is a common spot for mold.
4. Dissolve Grease with Vinegar. Place a dishwasher-safe cup filled with white vinegar on the top rack of an empty machine. Run a hot water cycle to break down grease and neutralize odors.
5. Freshen with Baking Soda. After the vinegar cycle finishes, sprinkle a cup of baking soda across the bottom of the tub. Run a short, hot rinse cycle to deodorize the interior.
6. Polish the Exterior Shine. Wipe down the control panel and door handle with a mild soap solution. If your unit is stainless steel, use a dedicated stainless steel polish to prevent fingerprints.
