Dacor Dishwasher Error Code LO

LO is a rinse aid level alert indicating that the rinse aid dispenser is running low and needs to be refilled. The dishwasher uses a sensor inside the dispenser to detect the level and alerts you before it runs completely empty. This is a routine maintenance notification, not a mechanical fault. Refilling the dispenser with rinse aid is all that is typically needed to resolve the code.

Resetting the dishwasher without refilling the rinse aid dispenser will not permanently clear the LO code. The alert is driven by the rinse aid sensor, so the code will return as long as the dispenser level remains low. Refilling the dispenser is the correct way to resolve the alert. A reset alone is not a substitute for adding rinse aid.

In most cases, resolving the LO code costs only the price of a bottle of rinse aid, typically in the range of $5 to $15. If the dispenser cap or seal needs replacement, parts generally cost between $10 and $30. A full dispenser assembly replacement, if the sensor or housing is damaged, can range from $30 to $80 or more depending on the specific model and where parts are sourced.

Open the rinse aid dispenser compartment, located on the inside of the dishwasher door, and fill it with a compatible rinse aid product until the reservoir is full. Replace the cap securely and run a wash cycle. The LO indicator should clear once the sensor detects the restored rinse aid level. If the code continues after refilling, inspect the dispenser cap, seal, and sensor for damage.

Running the dishwasher with the LO code active is generally safe and will not damage the appliance. However, without adequate rinse aid, you can expect water spots, streaks, or poor drying results on dishes and glassware. It is best to refill the dispenser promptly to maintain wash performance and protect glassware from mineral deposits over time.
