Dishwasher smells bad after a cycle

Plain-English steps to check safety and rule out the simple causes first.

If your dishwasher smells bad after a cycle, it usually means food debris or dirty water got trapped during the wash. Most of the time, it’s not dangerous yet — but if ignored, it can turn into a serious problem.

Start with these quick checks — most people clear the smell in under 10 minutes without tools.

1. Quick safety scan (10–30 seconds)

  • Smell burning or melting plastic?
  • See water around outlets or wiring?
  • Hear grinding or high-pitched squealing?
  • Is the control panel unusually warm or hot?
If any of those are present — STOP, turn the breaker OFF, and call a professional.

2. Main reasons dishwashers start to smell

  • Food debris stuck in filter or drain
  • Dirty water sitting for hours after the cycle
  • High heat + bacteria buildup
  • Clogged spray arms
  • Grease around door gasket

  1. Remove the lower rack
  2. Take out the filter and rinse under warm water
  3. Clean around drain area — labels / plastic / food bits?
