Electrolux Dishwasher Error Code i57

The i57 code on an Electrolux dishwasher indicates an MCB battery voltage plausibility and ADC fault related to the wash pump circuit. The control board monitors current changes in the wash pump and has detected that the current did not change by at least 0.0275 amperes within a 2.5-second period. This tells the board that the pump is not operating normally. The most likely causes are a wiring fault in the wash motor harness, a failed wash pump motor, or a defective main control board.

A reset may temporarily clear the i57 code, but if the underlying fault is still present, the error will return once the dishwasher attempts to run the wash pump again. Resetting is useful for confirming whether the fault is intermittent or persistent, but it does not repair a wiring issue, failed motor, or defective PCB. A proper diagnosis of the wash pump circuit is needed to permanently resolve the fault.

Repair costs vary depending on which component has failed. If the issue is a loose or corroded harness connector, the cost may be limited to a service call fee in the range of $75 to $150. Replacing a wash pump motor typically costs between $150 and $350 including parts and labor. If the main control board requires replacement, costs can range from $200 to $450 or more depending on the specific model and labor rates in your area.

Start by inspecting the wash motor wire harness and all connectors to the PCB for loose pins, corrosion, or visible damage. If the wiring looks intact, check the wash pump impeller for any blockage from foreign objects. If those checks do not resolve the fault, the wash pump motor may need to be tested for proper continuity and resistance, and replaced if it has failed. In cases where the harness and motor are both functional, the main control board may need to be replaced.

It is not recommended to continue running the dishwasher while the i57 fault is active. The code indicates the wash pump is not operating as expected, which means the dishwasher may not be circulating water properly and dishes will not be cleaned effectively. Running the appliance in this condition could also mask a wiring or motor fault that may worsen over time. Diagnose and repair the fault before resuming normal use.
