What Er31 means on a Fisher & Paykel cooktop

Er31 on a Fisher & Paykel cooktop is a software configuration status code rather than a true fault condition. It appears when the cooktop's control board has not yet been initialized with the appropriate software parameters, or when the unit is accessed in service mode before configuration is complete. The code is tied to the software initialization state of the main control module and does not indicate a failed component under normal circumstances.

This code is most commonly observed immediately after a control board replacement, a factory reset, or when a technician first enters the service menu on a newly installed unit. The cooktop's firmware requires a completed configuration sequence to recognize all connected components and zones correctly. Until that sequence is finalized, Er31 may display as a placeholder status.

The standard first step is to power cycle the cooktop for at least 10 seconds, cutting power fully at the circuit breaker or by unplugging the unit, then re-entering the service menu to complete initialization. If the code clears after this process and normal operation resumes, no further action is required. Persistent display of Er31 after repeated power cycles and service menu re-entry may indicate a deeper issue with the control board or its firmware.

Common causes of Er31

  1. 01

    Incomplete software initialization

    Wiring / connection

    The most frequent trigger is powering on the cooktop before the control software has completed its configuration sequence. This is expected behavior during initial setup or service mode entry and typically clears after a proper power cycle.

  2. 02

    Recent control board replacement

    Wiring / connection

    A newly installed control board will not have saved configuration data and may display Er31 until the service menu initialization is completed. The technician must re-enter the service menu and finalize the setup after any board swap.

  3. 03

    Factory reset performed

    Wiring / connection

    If a factory reset was carried out on the cooktop, the software reverts to an unconfigured state. Er31 will appear until the initialization process is run again through the service menu.

  4. 04

    Intermittent power interruption during startup

    Wiring / connection

    A brief power loss or voltage fluctuation during the boot sequence can interrupt software initialization and trigger Er31. A full 10-second power cycle allows the control board to restart the sequence cleanly.

  5. 05

    Control board firmware corruption

    Part replacement

    In rare cases where Er31 persists after multiple proper power cycles and service menu re-entries, the control board firmware may be corrupted or the board itself may be faulty, requiring board replacement or a firmware reload.

Frequently asked questions about Er31

What does Er31 mean on a Fisher & Paykel cooktop?
Er31 is a software configuration status code that appears when the cooktop's control software has not yet been fully initialized. It is considered a normal occurrence during service mode entry or after a control board replacement. It does not indicate a burned or shorted component in most cases. A 10-second power cycle followed by re-entering the service menu typically resolves it.
How do I fix Er31 on my Fisher & Paykel cooktop?
Turn off the cooktop at the circuit breaker or unplug it and leave it without power for at least 10 seconds. Restore power and re-enter the service menu to allow the software initialization to complete. If the error clears and the cooktop operates normally, no further steps are needed. If Er31 returns repeatedly, a technician should inspect the control board for firmware or hardware issues.
Is it safe to use my Fisher & Paykel cooktop when Er31 is displayed?
Er31 is a configuration status code, not a safety shutdown, but the cooktop may not operate correctly until initialization is complete. It is best to avoid cooking until the error is cleared and normal operation is confirmed. If the cooktop resumes normal function after a power cycle, it is safe to use.
Will resetting the cooktop clear the Er31 error?
Yes, in the majority of cases a power cycle of at least 10 seconds will clear Er31. After restoring power, re-entering the service menu allows the software to complete its configuration sequence and the error should no longer display. Persistent Er31 after multiple resets may require professional service.
How much does it cost to repair an Er31 error on a Fisher & Paykel cooktop?
If Er31 clears with a simple power cycle, there is no repair cost involved. If the issue requires a service call for control board inspection or firmware reload, labor costs typically range from $80 to $200 depending on your location. A full control board replacement, if needed, can add $150 to $400 or more in parts on top of labor.
