"It runs, but the dishes come out dirty" is one of the most common dishwasher complaints we hear — and often, the fix is something you can do tonight without a single tool. Try these five before you call.

The 5-minute fixes

  • 1. Clean the filter. Most modern dishwashers have a twist-out filter under the bottom spray arm. If it's coated in grease and food film, the machine is washing your dishes with dirty water. Rinse it under hot water with a brush.
  • 2. Free the spray arms. Spin each arm by hand and check the little holes for stuck food and seeds — a toothpick clears them.
  • 3. Start with hot water. Run the kitchen tap hot before starting the cycle, so the first fill isn't cold.
  • 4. Load for water, not capacity. Nothing blocking the spray arms, tall items to the sides, dirty faces angled toward the center.
  • 5. Refill the rinse aid. Cloudy film and water spots are usually a rinse-aid problem, not a machine problem.

When it's a real fault

If the fixes above don't change anything — or you're seeing standing water in the bottom, a cycle that never fills, error codes, or grinding noises — you're likely looking at a failing wash pump, water valve, or heating element. Those are repairs we do every day, usually in one visit because the parts are on our shelves, and always backed by the 6-month warranty.
