What LO means on a Electrolux refrigerator

The LO code on an Electrolux refrigerator is a notification generated by the control board indicating that the rinse aid level in the dispenser has dropped below the minimum threshold. The dispenser contains a float or optical sensor that monitors rinse aid volume and signals the control board when the reservoir is nearly empty. This is a status alert, not a fault condition, and the control board does not restrict any dishwasher functions when LO is active.

For homeowners, LO simply means your rinse aid dispenser is running low and needs to be refilled. Rinse aid helps water sheet off dishes during the final rinse cycle, reducing spots and improving drying performance. Without it, your dishes will still get clean, but you may notice more water spots or longer drying times.

The code will clear automatically once the dispenser is refilled to an adequate level. No reset procedure or service call is needed. Open the dispenser cap, located on the inside of the door, and add rinse aid until the reservoir is full. The indicator on the control panel should clear within the next wash cycle after the sensor detects the higher fluid level.

Common causes of LO

  1. 01

    Rinse aid reservoir is depleted or nearly empty

    Wiring / connection

    The most common reason for the LO code is simply that the rinse aid dispenser has been used down to a low level through normal operation. Refilling the dispenser resolves this immediately.

  2. 02

    Rinse aid dispenser cap not sealed properly

    Part replacement

    If the dispenser cap is loose or cracked, rinse aid can leak out faster than expected, causing the reservoir to read low sooner than the usage pattern would suggest. Inspect the cap for damage and ensure it clicks fully closed.

  3. 03

    Faulty rinse aid level sensor

    Part replacement

    The float or optical sensor inside the dispenser can fail or become coated with residue, causing it to report a low level even when the reservoir contains adequate rinse aid. Cleaning the sensor or replacing the dispenser assembly corrects this.

Frequently asked questions about LO

What does LO mean on an Electrolux refrigerator?
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.
Can I still use my dishwasher with the LO code active?
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.
How do I fix the LO code on my Electrolux dishwasher?
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.
How much does it cost to fix the LO code on an Electrolux dishwasher?
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.
Why does my Electrolux dishwasher show LO right after I refilled the rinse aid?
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.
