Electrolux Dishwasher Error Code i45

The i45 code means the pressure sensor produced a signal that was too low during its startup calibration check, when the tub should be empty. The control board considers this calibration reading invalid and stores the fault. The dishwasher compensates by using the last valid calibration data and allows the cycle to continue. The underlying sensor or tubing issue should still be diagnosed and repaired.

The dishwasher is designed to continue running using its previously stored calibration data when the i45 code appears, so it is not an immediate safety shutdown. However, running with an inaccurate water level sensor over time increases the risk of underfilling or overfilling, which could lead to poor wash results or water-related issues. It is best to address the fault within a reasonable timeframe rather than ignoring it indefinitely.

Repair costs vary depending on the root cause. If only cleaning the pressure tube or cleaning the air trap is needed, the cost may be minimal or just a service call fee, typically in the range of $75 to $150. Replacing the pressure sensor itself generally runs between $100 and $250 including parts and labor. A control board replacement is the most expensive scenario, often ranging from $200 to $400 or more depending on the model and labor rates in your area.

Some causes of the i45 code are DIY-friendly, such as clearing a blocked pressure tube, reconnecting a loose wiring connector, or cleaning the air trap in the sump. If the pressure sensor itself has failed or the control board is at fault, replacing those components typically requires a technician with the right tools and experience. Start with the simplest checks first, including the tube condition and connector integrity, before assuming the sensor needs replacement.

A power reset may temporarily clear the displayed code, but the i45 fault will return if the underlying cause, such as a faulty sensor, blocked tube, or bad connector, has not been corrected. The calibration check runs at each startup, so any persistent hardware fault will trigger the code again in subsequent cycles. A reset alone is not a fix.
