Dishwasher displays LO and may not start; indicates low rinse aid on some models.

Safety First: This is typically a maintenance indicator, not a hardware failure.

• 1. Refill rinse aid: Open the dispenser and fill with rinse aid until the indicator shows full.
• 2. Check cap seal: Ensure the rinse aid cap is properly seated and tightened to allow correct level sensing.
• 3. Reset indicator: On some models, the LO indicator will clear automatically after a few cycles; others may require a button sequence per the user manual.

If LO remains on with a full reservoir, the dispenser sensor may be faulty and the dispenser assembly may need replacement.
