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

Safety first: Switch off the dishwasher before adjusting racks or spray arms.

• Check loading: Ensure tall plates or pans are not blocking the dispenser door from opening fully.
• Clean upper spray arm: Remove and clean the upper spray arm to ensure strong water jets reach the dispenser area.
• Use appropriate program: Select a program with sufficient temperature and duration for tablets, or switch to powder if using very short cycles.
• Assess pump performance: If spray is weak, the circulation pump may be failing and require replacement.
