TL;DR
A dishwasher circulation pump is the main wash motor that pressurizes water and drives it through the rotating spray arms during the cycle, a separate component from the small drain pump that empties the tub. When it weakens or its impeller clogs with glass or food debris, the telltale is dishes coming out dirty while the machine fills and drains normally, often with a hum or grinding where wash noise should be.
What it means
A dishwasher circulation pump is the main wash motor that pressurizes water and drives it through the rotating spray arms during the cycle, a separate component from the small drain pump that empties the tub. When it weakens or its impeller clogs with glass or food debris, the telltale is dishes coming out dirty while the machine fills and drains normally, often with a hum or grinding where wash noise should be. Replacement involves sumps and seals under the tub, a mid-cost repair worth weighing against machine age.
