Dishwasher detergent tablet remains undissolved in the dispenser at the end of the cycle.

Safety first: Open the door carefully; steam may escape.

• Check loading: Ensure tall plates, pans, or cutlery are not blocking the dispenser door from opening fully.
• Clean dispenser: Wipe the dispenser compartment and lid to remove detergent residue that may cause sticking.
• Clean spray arms: Ensure the upper spray arm is clean and rotating freely to deliver water to the dispenser area.
• Use fresh detergent: Store tablets in a dry place and avoid using old or damp tablets that dissolve poorly.
• Program choice: Use a program with sufficient temperature and duration for tablets, as recommended by the detergent manufacturer.
