Error Code E98

Error Code E98: Inverter Communication Failure

Error code E98 signals a critical communication failure within your washing machine. Specifically, this indicates that the electronic control system responsible for managing the motor (the inverter electronics) is failing to communicate properly with the main operational control board of the appliance. This often results in the machine stopping operation mid-cycle or failing to start.

Possible causes and solutions:

• Faulty Main Control Unit (PCB): The main control board, often referred to as the central processing unit of the washing machine, may have developed an internal defect or component failure. This unit is responsible for sending the operational commands to the motor inverter. If the internal electronics within this board are damaged, the required communication signal will not be sent or received correctly, triggering the E98 error. Solution: Due to the complexity and high voltage involved in servicing main electronic boards, this repair requires specialized diagnostic tools and expertise. Contact an authorized service technician immediately for inspection and potential replacement of the control unit.

• Incorrect or Corrupted Configuration (Specific to EWM2000 Models): In certain appliance models, particularly those utilizing the EWM2000 system architecture, the communication link between the inverter and the main board relies on specific configuration parameters being set correctly during manufacturing or servicing. If these parameters have become corrupted, mismatched, or were incorrectly set during a previous service intervention, the system will interpret the resulting mismatched signals as a communication error (E98). Solution: You must verify that the stored configuration data matches the hardware installed in the machine. Consult your specific washing machine’s user manual or detailed technical documentation for instructions on accessing and verifying the configuration settings. If you are unable to locate this procedure or are unfamiliar with accessing deep diagnostic modes, contact customer support or an authorized service agent for assistance in validating or resetting the configuration parameters.
