Electrolux Dishwasher Error Code i0 (10 blinks)

The i0 code, displayed as 10 blinks, means the dishwasher did not detect rotation of the spray arms at a required checkpoint. These checkpoints occur at program start, at the beginning of each wash sub-program, and after any door open/close event or power interruption. The cycle will not proceed until the control board confirms that the spray arms are spinning. The most common reason is a physical obstruction preventing the arm from moving.

A reset will clear the active fault display temporarily, but the i0 error will return as soon as the dishwasher checks for spray arm rotation again if the underlying problem has not been resolved. The control board is designed to keep outputting this error until confirmed rotation is detected. You need to address the blockage or component failure before the code will stay cleared.

If the cause is simply an obstruction or clogged nozzles, there is no parts cost and only your time is required. Replacing a damaged spray arm assembly typically costs between $15 and $60 in parts depending on the model. If the rotation sensor or wiring harness needs replacement, parts costs generally range from $20 to $80, with additional labor costs if a technician is hired.

Start by opening the dishwasher and manually checking that both the upper and lower spray arms rotate freely by hand. Remove any utensils, lids, or dishes that may be blocking the arms. Also check the spray arm nozzle holes for mineral or food debris buildup and clear them if necessary. If the arms spin freely and the nozzles are clear but the error returns, the spray arm pivot or rotation sensor may need to be inspected and possibly replaced.

The dishwasher is designed to halt the cycle when this error is active, so it will not complete a wash program until the spray arm issue is corrected. Running the machine with blocked or non-rotating spray arms would also result in poor cleaning performance, as dishes would not receive adequate water coverage. Resolving the fault before continuing use is recommended.
