Dishwasher Leaving Dishes Dirty

Why a Dishwasher Leaves Dishes Dirty

A dishwasher that finishes a full cycle but leaves food residue or a cloudy film on dishes has a problem with water delivery, not the detergent. A clogged or blocked spray arm is the most common cause, since even one blocked jet reduces coverage across an entire rack. A failed wash pump can't build enough pressure to circulate water forcefully, leaving dishes rinsed but not scrubbed. A clogged filter beneath the lower rack restricts the water flow the pump needs, and the same debris that clogs it often ends up redeposited on dishes. Incorrect water temperature from a failed heating element also plays a role, since most detergents need hot water to dissolve fully and break down grease. A load that comes out dirty on the bottom rack but clean on top usually points to the spray arm or pump; a load that's uniformly dull points more toward temperature or filtration.
