Electrolux Refrigerator Error Code LO

The LO code on an Electrolux dishwasher indicates that the rinse aid level in the dispenser is low. The control board detected this through a level sensor inside the dispenser reservoir. This is a reminder notification only and does not indicate a mechanical failure or affect how the appliance operates.

Open the rinse aid dispenser cap on the inside of the door and fill the reservoir with rinse aid until full. The LO code should clear automatically after the next wash cycle once the level sensor detects the refilled reservoir. No manual reset is required.

If the LO code persists after refilling, the level sensor inside the dispenser may be coated with detergent residue or mineral deposits, preventing it from reading the fluid level accurately. Remove the dispenser cap and clean the inside of the reservoir with warm water. If the code still does not clear after running a full cycle, the sensor or the dispenser assembly itself may be faulty and need replacement.

Yes. The LO code does not disable any dishwasher functions. Your dishes will continue to wash normally. The only practical effect of running without rinse aid is that you may see more water spots on glassware and dishes may take longer to dry, since rinse aid helps water sheet off surfaces.

In most cases, the only cost is a bottle of rinse aid, which typically runs between $4 and $10 at grocery or hardware stores. If the LO code persists after refilling, the dispenser assembly or its level sensor may need replacement. A replacement dispenser assembly generally costs $20 to $60 in parts, and a technician visit to diagnose and install it would add $75 to $150 in labor depending on your area.
