Electrolux Washer Error Code 98

Error code 98 means the washer has detected an incompatibility between the main control board and the motor control board. These two boards must be matched versions to communicate correctly, and if they are mismatched or if the wiring between them is faulty, the machine will stop and display this code. The washer will not operate until the incompatibility is resolved.

A simple power reset is unlikely to permanently clear error code 98 because the condition it flags, a hardware or firmware incompatibility between the two control boards, is not resolved by cycling power. The code may temporarily disappear but will return as soon as the washer attempts to operate and the boards fail to communicate correctly. The underlying cause must be corrected first.

If the fix is simply reseating a loose connector or replacing a damaged wiring harness, repair costs are generally low, typically in the range of $50 to $150 including labor. If a motor control board replacement is needed, parts alone can range from $100 to $300 or more depending on the model, with additional labor costs if a technician is hired. Main control board replacements tend to fall in a similar price range.

A knowledgeable DIYer can start by inspecting the wiring harness between the main control board and the motor control board for loose connectors, damaged wires, or corrosion. If a board was recently replaced, verifying that the correct version was installed is an important next step. However, if the wiring is intact and a board replacement is needed, working with control boards requires care to avoid electrostatic damage and to ensure correct part matching.

The washer is designed to halt operation when this error is detected, so it will typically not run a cycle while code 98 is active. Attempting to force operation is not recommended, as a malfunctioning motor control circuit could cause unpredictable motor behavior. The machine should be left unplugged until the cause is diagnosed and corrected.
