Electrolux Dishwasher Error Code i59

The i59 code indicates a wash pump current reading fault detected by the main control board. The board's ADC circuit monitors current across the three phases of the wash pump motor and triggers this code when the combined current sum exceeds 40 mA for more than 300 milliseconds. The fault can originate in the wiring harness, the pump motor itself, or the current sensing circuitry on the control board.

It is not recommended to continue running the dishwasher while i59 is active. The code indicates an electrical fault in the wash pump circuit, and operating the appliance with a wiring short or a failing motor can cause further damage to the control board or create a potential safety hazard. The dishwasher should be left unpowered until the fault is diagnosed and resolved.

Repair costs vary depending on the root cause. Cleaning connectors or securing a loose harness involves minimal cost, typically just a service call fee ranging from $75 to $150. Replacing a wash pump motor generally costs between $150 and $350 including parts and labor. A main control board replacement is usually the most expensive repair, often ranging from $200 to $450 or more depending on part availability and labor rates in your area.

Some causes of i59, such as a loose harness connector, corroded terminals, or a debris-blocked pump impeller, can be addressed by a confident DIYer comfortable working with appliance wiring. However, diagnosing a faulty MCB ADC circuit or a motor with an internal winding short typically requires a multimeter and experience reading electrical components. If basic wiring and impeller checks do not resolve the fault, a qualified technician should evaluate the motor and control board.

A power reset may temporarily clear the i59 code, but if the underlying fault in the wiring harness, motor, or MCB current sensing chain is still present, the error will return once the dishwasher attempts to run the wash pump. Resetting without repairing the root cause is not a lasting solution and could allow repeated fault conditions to occur.
