What 157 means on a Fisher & Paykel dryer

Error code 157 on a Fisher & Paykel dryer is an alternate display representation of the ED fault code, which indicates that the model identity has not been defined within the control system. This fault originates in the electronic control board, specifically in the firmware or configuration memory that stores the appliance's model-specific parameters. When the dryer's control board cannot identify or confirm the machine model it is configured for, it cannot apply the correct operational logic, cycle timing, or safety thresholds, and will halt normal operation to display this code.

The most common root cause is a control board that has lost its programmed model configuration, either due to corrupted memory, a failed board, or a replacement board that has not been properly configured for the specific unit. This can also occur after a power surge or interruption that corrupts the non-volatile memory on the control board. In some cases, a control board replaced during a prior service call may not have been programmed with the correct model identity before installation.

Because the dryer cannot determine its own model identity, it treats all operational parameters as undefined and refuses to run safely. This is a control-level fault and is not related to any mechanical component, heating element, sensor, or motor. Resolving it requires addressing the control board configuration directly, which typically means reprogramming or replacing the control board with a correctly configured unit.

Common causes of 157

  1. 01

    Corrupted control board memory

    Part replacement

    The control board's non-volatile memory, which stores the model configuration, may have become corrupted due to a power surge, voltage fluctuation, or internal component failure. The board will need to be reprogrammed or replaced.

  2. 02

    Incorrectly configured replacement control board

    Wiring / connection

    If the control board was previously replaced, the new board may not have been programmed with the correct model identity for this specific dryer. Verify that the installed board matches and is configured for the correct model.

  3. 03

    Failed control board

    Part replacement

    Internal failure of the control board itself can prevent it from reading or retaining model configuration data. If the board cannot hold its programmed settings, it will trigger this fault on every startup.

  4. 04

    Power supply disruption during programming

    Wiring / connection

    A loss of power during a firmware update or initial configuration process can leave the board in an undefined state. This leaves the model identity field blank or unreadable.

Frequently asked questions about 157

What does 157 mean on a Fisher & Paykel dryer?
Error code 157 is an alternate display code for the ED fault, which means the dryer's control board cannot identify the model it is configured for. Without a defined model identity, the control system cannot apply the correct operating parameters and will not allow the dryer to run. This is a control board configuration issue, not a mechanical or sensor fault.
Can I fix error code 157 on my Fisher & Paykel dryer myself?
Resolving this fault generally requires reprogramming or replacing the control board, which is a task that typically falls outside standard DIY repair. If a control board was recently replaced, confirming it is the correct board for the model is a reasonable first check. For reprogramming or confirmed board replacement, a qualified appliance technician is recommended.
Is it safe to continue using my dryer when error code 157 is displayed?
The dryer will not operate normally when this code is active, as the control system refuses to run without a defined model configuration. There is no immediate safety hazard from the code itself, but the appliance should not be used until the fault is resolved, since the control board cannot enforce correct safety and operating limits.
How much does it cost to repair error code 157 on a Fisher & Paykel dryer?
If the issue is a corrupted or failed control board, repair costs typically range from around $150 to $400 or more, depending on parts pricing and labor rates in your area. If the fix involves only reprogramming an existing board, costs may be lower and limited primarily to a service call fee.
Will resetting my Fisher & Paykel dryer clear error code 157?
A power reset is unlikely to permanently clear error code 157, because the underlying cause is a missing or corrupted model configuration stored in the control board's memory. The fault will typically return immediately after a reset if the board's configuration has not been restored. A reset may be worth attempting as a first step, but a lasting fix requires addressing the control board directly.
