Detergent tablet remains partially or completely undissolved in the dispenser at the end of the cycle.

Safety first: Turn off power before inspecting the dispenser mechanism.

• Check dispenser door: Manually open and close the dispenser to ensure it moves freely and is not obstructed by dishes.
• Load correctly: Avoid placing tall items directly in front of the dispenser on the lower or upper rack.
• Clean spray arms: Ensure spray arms are not clogged and can rotate freely to direct water at the dispenser area.

If the dispenser door mechanism is weak or fails to open during a cycle, replace the detergent dispenser assembly.
