Electrolux Dishwasher Error Code i6A

The i6A code means the heater NTC temperature sensor is sending a measurement value that falls outside the allowed range for normal operation. The NTC sensor monitors heater or water temperature using a resistance-based signal, and the control board flags this code when that signal is too high or too low. The dishwasher will continue running, but the fault is stored in service mode memory. A technician can retrieve and clear it after diagnosing the sensor circuit.

The dishwasher is designed to continue its wash cycle even with the i6A fault active, so short-term use is possible. However, because the NTC sensor monitors heater temperature, a faulty sensor means the control system may not be able to accurately regulate heating. Running the appliance for an extended period without addressing the fault risks inadequate water heating or, less commonly, uncontrolled heater operation. It is best to have the sensor inspected promptly.

If only the heater NTC sensor needs replacement, parts typically range from $15 to $60 depending on the specific model, and a professional labor charge of $75 to $150 is common for this type of repair. If wiring harness repairs are needed, costs can be somewhat higher. A control board replacement, if required, is the most expensive scenario and can range from $150 to $350 or more for parts alone.

A knowledgeable DIYer can start by inspecting the NTC sensor connector for corrosion or looseness and reseating the plug, which costs nothing and sometimes resolves intermittent faults. If the connector looks fine, replacing the heater NTC sensor is the next step and is generally straightforward once the dishwasher is accessed. However, if the wiring harness is damaged or a control board issue is suspected, professional repair is recommended.

A power reset may temporarily clear the displayed indication, but the i6A fault is stored in service mode memory and will typically return if the underlying sensor or wiring problem is still present. Permanently clearing the code requires addressing the root cause, such as replacing the NTC sensor or repairing the wiring, and then clearing the stored fault through service mode diagnostics.
