Electrolux Dishwasher Error Code LO

The LO code on an Electrolux dishwasher means the control board has detected that the rinse aid dispenser is running low on rinse agent. A sensor inside the dispenser monitors the fluid level and sends this signal to the control. The code is a maintenance reminder and not a malfunction, but drying performance may suffer until the dispenser is refilled.

Yes, it is generally safe to continue running the dishwasher when the LO code is displayed. The code is a maintenance alert and does not indicate a mechanical failure or safety issue. However, running the dishwasher without rinse aid will likely result in poorer drying performance and water spots on dishes and glassware.

If the issue is simply an empty dispenser, the only cost is the rinse aid itself, which typically runs a few dollars per bottle. If the dispenser assembly or level sensor needs replacement, parts and labor costs can range from roughly $40 to $150 depending on the part and whether professional service is needed. Cleaning the dispenser to remove residue buildup involves no parts cost and can often be done at home.

The first step is to open the rinse aid dispenser, located on the interior side of the door, and fill it with rinse aid until the indicator shows it is full. The LO alert should clear on its own after the dispenser is refilled and a cycle is run. If the code persists after filling, inspect the dispenser for cracks, residue buildup, or a faulty level sensor.

Resetting the dishwasher alone will not permanently clear the LO code because the level sensor will continue to detect low rinse aid and signal the control board. The correct fix is to refill the rinse aid dispenser, after which the alert should clear on its own. A reset may temporarily dismiss the display, but the code will return if the rinse aid level remains low.
