What LO Means
LO on Frigidaire dishwashers that use this display is a reminder that the rinse aid dispenser is low. It is informational, not a malfunction.
Common Causes of LO
- Rinse aid used up
🔧 One Safe Check You Can Try
Open the rinse aid cap inside the door, fill with liquid rinse aid to the fill line, wipe up any spill (spilled rinse aid can cause foaming), and close the cap until it clicks.
⚠ Why You Shouldn't Go Further Than That
- None — refilling rinse aid is routine owner maintenance.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
