Frigidaire Dishwasher LO — Low rinse aid

Frigidaire Dishwasher · Error code LO

What LO Means

Indicator that the rinse aid dispenser is empty or nearly empty. Not a fault — just a refill reminder.

Symptoms

  • LO indicator lit on control panel
  • Spotty or wet dishes at end of cycle
  • Dishwasher otherwise runs normally

Common Causes

1
Rinse aid reservoir empty

Normal use depletes the reservoir every 1-3 months.

2
Rinse aid dispenser cap not seated

If cap is loose, sensor can read empty.

3
Faulty rinse aid level sensor

Less common — magnetic float sensor failed.

How to Fix It

  1. Open the door and unscrew the rinse aid cap (usually next to the detergent cup).
  2. Refill with rinse aid until the indicator window darkens.
  3. Seat the cap fully and wipe spills.
  4. If LO returns immediately with a full reservoir, replace the dispenser assembly.
