Why Are My Dishes Still Dirty After the Dishwasher?
Cloudy glasses, gritty plates, or leftover food residue after a full cycle almost always trace back to one of three overlooked causes. Here is how to tell which one you have.
Cloudy glasses, gritty plates, or leftover food residue after a full cycle almost always trace back to one of three overlooked causes. Here is how to tell which one you have.
A dishwasher that runs its full cycle but leaves dishes dirty is one of the most common complaints we hear, and the good news is that most causes are simple to identify once you know what to look for.
The spray arms have small holes that distribute water evenly across every rack. Over time, mineral deposits and food particles can clog these holes, leaving parts of the load untouched by water. This is the single most common cause of food residue left on dishes after a cycle.
If your dishes come out cloudy rather than dirty, hard water minerals are the more likely culprit. These deposits build up on glass surfaces over repeated washes and are a water chemistry issue rather than a mechanical failure.
Large plates, pans, or utensils that block the spray arm's rotation path can shadow other dishes from water and detergent, leaving streaks or spots even when everything else is working correctly.
If cleaning the spray arms and running a cleaning cycle does not solve the problem, the issue may be with the water inlet valve, the wash pump, or the door gasket allowing detergent to leak out during the cycle. These components require testing tools to diagnose accurately.

This most often points to clogged spray arm holes, which prevent water from reaching every part of the load evenly.
Most spray arms lift out for cleaning. Soaking them in warm water and using a toothpick to clear each hole usually restores full spray coverage.
A gritty film is commonly caused by using too much detergent, using the wrong detergent type, or a rinse aid dispenser that is empty or malfunctioning.
