Dishwasher fills with water but the wash cycle is very quiet and dishes come out dirty; spray arms do not seem to move.

Safety first: Turn off power and allow hot water to cool before working inside.

• Verify water level: Confirm the tub has adequate water. If low, address fill issues first.
• Check spray arm movement: Start a cycle, wait a few minutes, then open the door quickly. If spray arms are in the same position and dishes are barely wet, circulation is not occurring.
• Inspect for debris: Remove filters and look into the pump intake for broken glass or debris blocking the impeller. Remove carefully.

If the pump still does not run or only hums, the circulation pump and motor assembly likely needs replacement, which is a complex under-base repair best done by a technician.
