Fisher & Paykel Washer Error Code 103

Error code 103 means the washer has detected a communications timeout between the main control board and the slave display module. The two boards communicate over a serial data bus, and the main controller stopped receiving expected responses from the slave display. Fisher & Paykel directs technicians to use the Fault Code 106 diagnostic procedure to identify the specific cause.

No, you should not attempt to run a wash cycle while error code 103 is active. The washer has halted because communication between its control boards has failed, meaning the machine cannot reliably control or display its operation. Continuing to use it in this state could cause incomplete cycles or further damage to electronic components.

A power reset, such as unplugging the washer for several minutes, may temporarily clear the fault code if the communication interruption was caused by a transient issue. However, if the underlying cause is a hardware fault such as a damaged connector, broken wire, or failed board, the error code will return once the machine attempts to resume operation. A proper diagnosis following the Fault Code 106 procedure is needed for a lasting fix.

Some causes of error 103, such as a loose wiring connector, can be addressed by a confident DIYer who is comfortable accessing internal components after disconnecting power. However, diagnosing a failed slave display board or main control board requires board substitution and a structured diagnostic process, which is better suited to a qualified appliance technician. Always disconnect the washer from power before inspecting any internal wiring.

Repair costs depend on the root cause. If the issue is a loose connector, a service call alone may resolve it, typically ranging from $80 to $150 for the visit. Replacing a slave display board generally adds $100 to $300 in parts, while a main control board replacement can add $150 to $400 or more in parts, plus labor.
