Frigidaire Dishwasher Error Code i52

The i52 code means the control board has detected an abnormally high current of approximately 1.3 amps from the wash pump's brushless DC motor. The board's hardware supervision circuit triggers this fault to protect the motor and electronics from damage. It indicates a problem in the wash pump motor, its wiring harness, or the PCB motor driver.

A reset may temporarily clear the i52 code, but the fault will return if the underlying cause is not corrected. Because the code is triggered by a hardware protection circuit responding to a real electrical condition, the motor, wiring, or pump must be inspected and repaired before the dishwasher will operate normally. Repeated resets without fixing the root cause can risk further damage.

Repair costs vary depending on the cause. Clearing a debris jam is essentially free if done yourself, while a replacement wash pump motor typically costs between $80 and $200 for the part alone. A new PCB can range from $100 to $300 or more. Adding professional labor, total repair costs generally fall between $150 and $500 depending on the failed component and local service rates.

Some causes of the i52 error are DIY-friendly, such as clearing a jammed impeller or reseating a loose wire harness connector. However, diagnosing winding shorts, testing motor resistance, or replacing the PCB requires electrical knowledge and proper tools. If you are not comfortable working with appliance wiring, a qualified technician should handle the repair.

No, you should not continue running the dishwasher while the i52 error is active. The code indicates the wash motor is experiencing an abnormal electrical condition, and continued operation could damage the motor, the PCB, or the wiring. Leave the dishwasher off until the cause has been diagnosed and corrected.
