Fisher & Paykel Washer Error Code 161

Error code 161 on a Fisher & Paykel washer indicates a Hardware/EEPROM Supply Mismatch detected by the Motor Controller module. During power-up, the Motor Controller performs a self-check that compares the detected hardware voltage configuration (either 110V or 230V) against the corresponding supply voltage table stored in the EEPROM. When the values do not align during phases 2 through 6 of this startup sequence, the controller throws error 161 and halts normal operation to prevent damage from running components at an incorrect voltage.

The Motor Controller module contains onboard EEPROM memory that stores configuration data including the expected supply voltage profile. If the EEPROM data has become corrupted, if the module was incorrectly configured for a different market voltage, or if the module itself has developed a hardware fault, the mismatch condition will be detected consistently on every power cycle. This is not a transient sensor error but a fundamental disagreement between what the hardware detects and what the EEPROM expects.

Because the fault originates within the Motor Controller itself, the primary and recommended corrective action is replacement of the Motor Controller module. There is no field-level EEPROM reprogramming procedure for this condition. The mismatch cannot be resolved by resetting the machine or by checking external wiring, as the conflict is internal to the controller board.
