Dishwasher leaves detergent tablet partially undissolved in the dispenser.

Safety first: Turn off power before removing spray arms or working near the door latch.

• Check loading: Ensure large plates or pans are not blocking the detergent dispenser door from opening fully.
• Clean spray arms: Remove and clean the upper and lower spray arms to ensure strong water jets reach the dispenser area.
• Verify water temperature: Run the hot water tap at the sink before starting the dishwasher so incoming water is warm.
• Test dispenser door: Start a cycle and listen for the dispenser opening. If it does not open, replace the detergent dispenser assembly.
