Electrolux Dishwasher Error Code i0 (2 blinks)

The i0 error (2 blinks) indicates a drain pump fault where the pressure switch did not reach its reset point within 120 seconds during the drain cycle. The dishwasher is detecting that water is not draining fast enough or completely enough in the required time. The control board halts the program until the issue is resolved. It points to a problem in the drain pump, drain hose, or pressure switch.

Pressing the program button will resume the cycle and clear the active fault display, but only after you have resolved the underlying drain problem. If the drain issue is not fixed, the dishwasher will attempt to drain again and re-trigger the i0 fault within the same or next cycle. A reset without a repair is a temporary workaround and the error will return.

If the cause is simply a clogged filter or kinked hose, the repair costs nothing beyond your time. Replacing a faulty drain pump motor typically runs between $80 and $200 for the part, plus labor if a technician is hired, bringing the total repair cost to roughly $150 to $350 depending on your area. A pressure switch replacement is generally less expensive, often in the $20 to $60 range for the part alone.

Start by cleaning the pump filter and checking for debris jammed in the drain pump impeller, as this is the most common cause. Next, inspect the drain hose for kinks or clogs, and verify the connection at the sink air gap or garbage disposal is clear. If the drain path is unobstructed and the pump still does not run, test the pump motor and pressure switch for electrical faults. Once the issue is corrected, press the program button to resume the halted cycle.

It is not recommended to continue running the dishwasher while the i0 fault is active. The program is halted because water may still be standing in the tub, and running another cycle without resolving the drain fault could cause water to overflow or remain stagnant. Address the drain issue before resuming normal operation.
