What 85 means on a Fisher & Paykel washer

Error code 85 on a Fisher & Paykel washer indicates a Phase 2-3 communications failure between the display board and the motor controller. These two boards must continuously exchange data signals during operation to coordinate wash cycles, motor speed, and user inputs. When that communication link breaks down or becomes corrupted, the machine cannot safely continue and halts with this error. The designation "Phase 2-3" refers to a specific stage in the communication handshake protocol between these two control assemblies.

The most common root causes include a faulty wiring harness or connector between the display and motor controller, a damaged or failed display board, or a defective motor controller board. Loose, corroded, or broken connector pins can interrupt the data signal even if the wiring appears intact at a glance. Both boards must be functioning correctly and communicating at the proper voltage levels for normal operation to resume. Fisher & Paykel technical documentation directs technicians to reference fault code 106 for the specific diagnostic and repair actions associated with this error, as code 106 provides the detailed corrective procedure that applies to this communication failure.

Common causes of 85

  1. 01

    Faulty wiring harness or connectors

    Wiring / connection

    The cable connecting the display board to the motor controller may have a loose, corroded, or broken connector pin, interrupting the data signal. Inspect all connectors between the two boards for damage, corrosion, or incomplete seating.

  2. 02

    Failed display board

    Part replacement

    If the display board has failed internally, it cannot send or receive communications to the motor controller. This typically requires board replacement after ruling out wiring issues.

  3. 03

    Failed motor controller board

    Part replacement

    A defective motor controller board may be unable to respond to signals from the display board, triggering this error. Diagnosis should follow the steps outlined under fault code 106 before replacing this component.

  4. 04

    Intermittent connection due to vibration

    Wiring / connection

    Repeated machine vibration during spin cycles can loosen connectors over time, causing a communication link that works intermittently before failing completely. Check that all harness connectors are firmly seated and undamaged.

Frequently asked questions about 85

What does 85 mean on a Fisher & Paykel washer?
Error code 85 indicates a Phase 2-3 communications error between the display board and the motor controller. These two control boards exchange data continuously during operation, and when that link fails, the washer shuts down and displays this code. Fisher & Paykel directs technicians to consult fault code 106 for the specific diagnostic steps to resolve this error.
Can I fix error code 85 on my Fisher & Paykel washer myself?
Some basic checks, like inspecting visible wiring connectors for looseness or corrosion, are within reach for a handy DIYer. However, diagnosing which control board has failed requires following the technical procedure outlined under fault code 106, which involves working with internal electronics. Most homeowners will benefit from having a qualified appliance technician handle this repair.
Will resetting my Fisher & Paykel washer clear error code 85?
A power cycle reset may temporarily clear the error if the cause is an intermittent connection, but the code will return if the underlying communication fault is not corrected. If the display board, motor controller, or wiring harness has a hardware fault, a reset will not resolve the problem. A proper diagnosis following the fault code 106 procedure is needed to achieve a lasting fix.
Is it safe to use my Fisher & Paykel washer while error code 85 is showing?
No, the washer should not be operated while this error is active. The machine has halted because the display and motor controller cannot communicate, which means the system cannot properly control motor operation or respond to user commands. Continuing to attempt operation could risk further damage to the control boards.
How much does it cost to repair a Fisher & Paykel washer showing error code 85?
Repair costs depend on which component has failed. If only the wiring harness or connectors need attention, costs may be relatively low, typically in the range of $75 to $150 for a service call. If one or both control boards require replacement, costs can range from $200 to $500 or more depending on parts and labor rates in your area.
