Dishwasher displays U10 and beeps, often at the end of the cycle with poor drying.

• Refill rinse aid: Open the rinse aid compartment and fill to the maximum line with a suitable rinse aid.
• Adjust dosage: Set the rinse aid dosage level according to water hardness (refer to the Panasonic manual). Higher hardness usually needs a higher setting.
• Clean the outlet: Wipe the dispenser outlet and surrounding area to remove dried residue.

After refilling and adjusting, run a hot cycle to verify improved drying.
