Fisher & Paykel Washer Error Code 20

Error code 20 means the Display Module and Motor Controller started up out of sequence with each other. These two control boards must communicate in a specific order during startup, and when that timing is disrupted, the machine stops and displays this fault. It can be caused by anything from a brief power fluctuation to a failing control board.

Start by turning the washer off at the wall outlet and waiting 5 seconds before turning it back on. If the error persists, disable the auto-restart feature and run the machine again to see if a different fault code appears. That new code will give a more specific direction for diagnosing the faulty component, which may be the Display Module, Motor Controller, or the wiring between them.

If a simple power reset clears the fault, there is no cost. If a control board needs replacement, parts alone can range from roughly 80 to 300 dollars depending on whether the Display Module or Motor Controller is at fault, with labor adding additional cost if a technician is required. Getting a precise diagnosis first by disabling auto-restart and checking for a secondary fault code can help avoid replacing the wrong component.

Yes, in many cases a power cycle will clear error code 20, especially if the fault was caused by a transient power issue. Turn the machine off at the wall, wait at least 5 seconds, then turn it back on. If the code returns after the reset, the fault is likely related to a hardware problem that needs further diagnosis.

Error code 20 is not typically a safety hazard. The machine stops as a precaution when the control boards fall out of sync, which prevents uncontrolled motor operation. However, you should avoid repeatedly forcing the machine to restart without investigating the cause, as an underlying wiring or board fault left unrepaired could worsen over time.
