Electrolux Dishwasher Error Code i0 (3 blinks)

The i0 error with 3 blinks means the Aqua-Control flood protection system has detected water in the base tray beneath the dishwasher tub. When this happens, the dishwasher immediately shuts off the inlet water valve and pauses the active wash program. The system is designed to protect your home from water damage caused by an internal leak. You will need to locate and repair the source of the leak before normal operation can safely continue.

No, you should not run the dishwasher while the i0 code is active. The Aqua-Control system shut off the water supply specifically because water was detected where it should not be. Continuing to operate the appliance before finding and fixing the leak risks worsening water damage to your floor and cabinetry. Wait until the base tray is dry, the float switch has reset, and the leak source has been repaired.

Repair costs vary widely depending on the cause of the leak. A replacement door gasket typically falls in the range of $15 to $50 for the part, while a new inlet valve can range from $25 to $80. If a technician is needed for diagnosis and labor, total repair costs generally range from $100 to $300 depending on the component involved and local labor rates. Identifying the exact leak source before ordering parts will help avoid unnecessary expenses.

Some causes of the i0 error are DIY-friendly, such as clearing a stuck float switch, tightening a loose hose clamp, or switching to the correct detergent. However, if the leak source is a faulty inlet valve, cracked pump housing, or damaged door seal, those repairs require part replacement and some disassembly. If you cannot identify a clear leak source after inspecting the base tray and hose connections, a technician can use the access panel to trace the leak more thoroughly.

A manual reset alone will not permanently clear the i0 error if water remains in the base tray or the float switch is still raised. The dishwasher is designed to resume automatically once the tray dries out and the float drops back to its resting position. If you reset the appliance without addressing the underlying leak, the error will return as soon as water re-enters the base tray during the next cycle.
