Detergent pod or powder remains in the dispenser cup at the end of the cycle.

Safety note: Most checks can be done without removing power, but disconnect power before removing the inner door panel.

• Load correctly: Ensure tall items in the lower rack are not blocking the dispenser door from swinging open.
• Clean dispenser: Wipe the dispenser cup and door with warm water to remove caked-on detergent.
• Test door action: Manually close and release the dispenser door. It should snap open firmly. If weak, replace the dispenser assembly.
• Check actuator: If the door is mechanically sound but not opening during a cycle, the actuator or control board may be faulty and require replacement.
