Dishwasher leaves detergent (powder, pod, or tablet) partially undissolved in the dispenser or tub.

Safety first: Turn off power before removing spray arms if accessing from below.

• Check dispenser door: Ensure the detergent cup door opens fully and is not blocked by the upper rack or large dishes.
• Clean spray arms: Clear any clogged jets, especially those aimed at the dispenser area.
• Verify water level and temperature: Confirm the dishwasher fills to the proper level and that water is hot. Address fill or heating issues if present.
• Use correct detergent placement: Place pods in the dispenser, not in the bottom of the tub, and avoid overfilling powder.
