Frigidaire Dishwasher Error Code i57

The i57 code indicates a wash motor current plausibility fault. The control board monitors the wash pump motor and expects to see the current change by at least 0.0275 amperes within 2.5 seconds. When that change is not detected, the board logs the i57 fault and stops the cycle. This points to a problem with the wash motor wiring, connectors, the motor itself, or in rarer cases the control board.

No, you should not attempt to run the dishwasher while the i57 fault is active. The appliance has halted operation because a motor circuit fault was detected, and forcing operation could worsen the underlying electrical issue or damage additional components. Leave the dishwasher off until the problem is diagnosed and repaired.

Repair costs depend on which component is at fault. Wiring harness repairs or connector replacements are typically the least expensive, often ranging from around $50 to $150 including labor. A wash motor replacement generally costs between $150 and $350 depending on parts and labor rates in your area. PCB replacement is usually the most expensive option, often ranging from $200 to $450 or more.

Start by inspecting the wash motor wire harness and all connector points between the motor and the PCB for loose pins, corrosion, or damage. If the wiring checks out, test the wash pump motor for proper operation and resistance. If both the wiring and motor appear functional, the PCB may need to be evaluated or replaced by a qualified technician.

A power reset may temporarily clear the code and allow the machine to attempt a new cycle, but the fault will return if the underlying problem with the wash motor circuit has not been corrected. A reset is only useful as a first step to confirm whether the fault is intermittent. Persistent i57 codes require proper diagnosis of the wiring, motor, and control board.
