Electrolux Dishwasher Error Code iA0

The iA0 code means the dishwasher checked for spray arm rotation at the start of a programme or subprogramme and received no detection signal. The machine monitors spray arm movement using a magnet and sensor system, and when no rotation is confirmed, it logs this fault. The most likely causes are a physical obstruction blocking the arm, clogged nozzles reducing water pressure, or a worn bearing or faulty magnet in the spray arm assembly.

Resetting the dishwasher may clear the displayed fault temporarily, but the iA0 code will return at the start of the next cycle if the underlying cause has not been resolved. Because the rotation check runs automatically at each programme and subprogramme start, the sensor must successfully detect arm movement before the fault stays cleared. Fix the physical or mechanical cause first, then run a full cycle to confirm the error does not reappear.

If the fix is simply clearing a blockage or unclogging nozzles, the cost is nothing beyond a few minutes of time. Replacing a spray arm assembly, which addresses a worn bearing or faulty magnet, typically costs in the range of $15 to $60 for the part depending on the model. If the rotation sensor or wiring is faulty and a technician is needed, total repair costs including labor can range from $80 to $200 or more depending on your location and the specific components involved.

Start by unloading and reloading the dishwasher, making sure no items are hanging below the rack or touching the spray arms. Remove the spray arms and clear any clogged nozzles with a thin tool or warm water soak. Check that the spray arm spins freely by hand with light resistance only. If the arm spins freely and the nozzles are clear, inspect the bearing hub and the magnet for wear or displacement, replacing the spray arm assembly if necessary.

Running the dishwasher with an active iA0 fault means the spray arm is not rotating, so dishes will not be cleaned properly and water distribution inside the tub will be uneven. While this does not present an immediate safety hazard in most cases, continued operation without resolving the fault provides no useful cleaning and may mask a developing mechanical issue. It is best to diagnose and fix the cause before running further cycles.
