Frigidaire Dishwasher Error Code i5C

The i5C code means the control board has detected abnormally high current of approximately 0.7 amps in the drain pump's Brushless DC motor. The dishwasher's hardware supervision circuit monitors the drain motor continuously and shuts down when current exceeds the normal operating range. This is a protective fault designed to prevent motor and board damage. The most likely causes are a blocked pump impeller, a wiring harness issue, or a failing drain motor.

You should not continue running the dishwasher while the i5C fault is active. The code indicates the drain motor is drawing excessive current, and operating the appliance under this condition risks overheating the motor or damaging the control board. Power down the dishwasher and diagnose the fault before attempting to run a cycle.

Repair costs depend on the cause. If the fix is simply clearing a drain pump blockage, there may be no parts cost at all, though a service call typically runs between $75 and $150. A replacement drain pump motor usually costs between $40 and $120 for the part, with labor adding to the total. A main control board replacement is the most expensive scenario, with parts ranging from $100 to $250 or more depending on the model.

Some causes of the i5C error are DIY-friendly. Clearing a blocked drain pump impeller requires removing the filter assembly and inspecting the pump, which most homeowners can do with basic tools. Inspecting and reseating the motor wire harness connector is also straightforward. However, replacing the drain pump motor or the PCB involves working with electrical components and is best handled by a qualified technician if you are not comfortable with appliance repair.

A power reset may temporarily clear the i5C code, but it will return if the underlying cause is not resolved. The control board's supervision circuit will detect the overcurrent condition again as soon as the drain pump is activated during a cycle. Address the root cause, such as removing a blockage or repairing the wiring, before relying on a reset to restore normal operation.
