What 19 means on a Fisher & Paykel washer

Error code 19 on a Fisher & Paykel washer indicates a communication synchronization fault between two core control systems: the Display Module and the Motor Controller. These two boards are designed to operate in a coordinated sequence, and when their communication timing falls out of alignment, the machine raises this fault to prevent erratic or unsafe operation. The error does not necessarily mean either board has failed outright, but rather that they are not handshaking correctly during the startup or operating cycle.

The most common trigger for this fault is a transient power issue, such as a brief voltage fluctuation or an interrupted power cycle, that causes one controller to initialize before the other is ready. This desynchronization can also result from a loose or corroded wiring harness connection between the two modules, which disrupts the data signal exchanged between them. In some cases, a firmware or internal memory state on one of the boards becomes corrupted, causing persistent sequencing failures even after power is restored.

Diagnostic procedure begins with a hard reset: switch the machine off at the wall outlet, wait a minimum of 5 seconds to allow capacitors to fully discharge, then restore power. If the fault clears, the cause was likely a temporary power disruption. If error code 19 returns, the next step is to disable the auto restart function and retest the machine. Running without auto restart allows any new or underlying fault code to surface, which can then be used to pinpoint the specific failing component, whether that is a wiring harness, the Display Module, or the Motor Controller board itself.

Common causes of 19

  1. 01

    Transient power disruption

    Wiring / connection

    A brief voltage spike, brownout, or interrupted power cycle can cause the Display Module and Motor Controller to initialize out of sequence. A full power reset by switching off at the wall for at least 5 seconds often resolves this.

  2. 02

    Loose or corroded wiring harness connection

    Wiring / connection

    If the wiring harness connecting the Display Module to the Motor Controller has a loose plug or corroded terminals, the communication signal between the two boards can drop intermittently, triggering this fault. Inspect connectors at both boards for secure seating and signs of corrosion.

  3. 03

    Corrupted controller board state

    Part replacement

    An internal memory or firmware state on either the Display Module or Motor Controller can become corrupted, causing persistent sequencing failures that survive a basic power reset. Disabling auto restart and rechecking for a new fault code can help identify which board is affected.

  4. 04

    Faulty Display Module

    Part replacement

    If the Display Module has failed or is intermittently malfunctioning, it may not send or receive synchronization signals correctly, causing the Motor Controller to flag an out-of-sequence condition. This is typically confirmed after ruling out wiring issues and power faults.

  5. 05

    Faulty Motor Controller board

    Part replacement

    A defective Motor Controller may fail to complete its initialization handshake with the Display Module on time, triggering error code 19. This is usually identified after the auto restart is disabled and a secondary diagnostic fault code points specifically to the motor control circuit.

Frequently asked questions about 19

What does 19 mean on a Fisher & Paykel washer?
Error code 19 means the Display Module and Motor Controller are running out of sequence, indicating a communication synchronization fault between these two control boards. The machine stops operation to prevent unsafe behavior when the two systems are not coordinating correctly. It can be caused by a power fluctuation, a wiring issue, or a problem with one of the control boards.
Will resetting my Fisher & Paykel washer clear error code 19?
A power reset resolves error code 19 in many cases, particularly when the fault was triggered by a temporary power disruption. Turn the machine off at the wall outlet, wait at least 5 seconds, then turn it back on. If the code returns after the reset, the underlying cause requires further diagnosis and the auto restart function should be disabled to allow any new fault code to appear.
How do I fix error code 19 on a Fisher & Paykel washer?
Start by switching the washer off at the wall for at least 5 seconds and then restoring power. If the fault persists, disable the auto restart feature and retest so that any new fault code can surface and guide further diagnosis. From there, inspect the wiring harness connections between the Display Module and Motor Controller for loose or corroded terminals. If wiring checks out, one of the two control boards may need to be replaced.
Is it safe to keep using my washer when error code 19 is showing?
It is not recommended to continue running the washer while error code 19 is active. The fault indicates the control systems are out of sync, which means the machine may not behave predictably during a wash cycle. Attempting a power reset first is safe, but if the fault returns, the washer should remain out of service until the cause is identified and corrected.
How much does it cost to repair error code 19 on a Fisher & Paykel washer?
If the fault is resolved by a simple power reset, there is no parts cost involved. If a wiring harness repair is needed, costs are typically in the range of a basic service call fee plus labor. Replacing a Display Module or Motor Controller board generally costs more, with parts and labor combined often ranging from around $150 to $400 or more depending on parts availability and local labor rates.
