What E7:02 means on a Fisher & Paykel washer

Error code E7:02 on a Fisher & Paykel washer indicates that the motor control module has detected a loss of phase in the drive motor circuit. The washer motor is a three-phase motor, meaning it requires three separate electrical phases to operate correctly. When one of these phases is interrupted or missing, the motor cannot generate the proper rotating magnetic field needed to spin the drum. The control module continuously monitors all three phases during operation, and when it detects that one phase has dropped out, it halts the motor and triggers this fault code.

The most direct way to diagnose this fault is to measure resistance between each phase pair at the motor control module connector. At 20 degrees Celsius, the correct resistance between phases should be 28 ohms plus or minus 1.95 ohms. A reading that falls significantly outside this range, or an open circuit reading on any phase pair, points to a break in continuity somewhere in the motor circuit. This could be in the wiring harness, the connectors between the module and motor, or within the motor windings themselves.

Common causes include damaged or corroded wiring harness connectors, broken wires within the motor harness, and failed motor windings. Physical inspection of the harness routing and connector pins should accompany resistance testing. If the harness and connectors measure correctly, the fault may lie within the motor control module itself, which can fail internally and misread or fail to deliver the correct phase output to the motor.

Common causes of E7:02

  1. 01

    Damaged or disconnected motor harness connector

    Wiring / connection

    A loose, corroded, or physically damaged connector between the motor and the motor control module can break continuity on one phase. Inspect all connector pins and sockets for corrosion, bent pins, or incomplete seating.

  2. 02

    Broken wire in the motor harness

    Part replacement

    Wiring inside the motor harness can crack or break due to repeated movement or heat exposure, causing an open circuit on one phase. Resistance testing between phases at the control module connector at 20 degrees Celsius should read 28 ohms plus or minus 1.95 ohms; a significantly different reading or open circuit indicates a wire fault.

  3. 03

    Failed motor windings

    Part replacement

    An internal open or shorted winding inside the motor will cause one phase to read out of range or show no continuity. If the harness and connectors are intact and resistance readings are abnormal, the motor itself may need replacement.

  4. 04

    Faulty motor control module

    Part replacement

    The motor control module can fail internally, either failing to deliver a full phase output to the motor or incorrectly detecting a phase loss when all motor components are functional. This is typically diagnosed after the harness and motor have been confirmed good.

Frequently asked questions about E7:02

What does E7:02 mean on a Fisher & Paykel washer?
E7:02 means the motor control module has detected a loss of one phase in the drive motor circuit. The washer motor requires three electrical phases to operate, and when one is missing or interrupted, the machine stops and displays this code. The fault can originate in the wiring harness, the connectors, the motor windings, or the motor control module itself.
Can I fix E7:02 on my Fisher & Paykel washer myself?
A knowledgeable DIYer can begin by inspecting the motor harness and connectors for visible damage, corrosion, or loose connections. Resistance testing between the motor phases at the control module connector is the recommended first diagnostic step, with a target reading of 28 ohms plus or minus 1.95 ohms at 20 degrees Celsius. If the harness and connectors appear sound and readings are within spec, further diagnosis or component replacement may require a qualified technician.
Will resetting my washer clear the E7:02 error?
Resetting the washer may temporarily clear the error code from the display, but the fault will return as soon as the machine attempts to run the motor if the underlying problem has not been fixed. The motor control module monitors phase continuity during operation, so the code will reappear until the wiring, connector, or component issue is properly resolved.
Is it safe to use my Fisher & Paykel washer when E7:02 is displayed?
The washer should not be operated while this fault code is active. Running the motor with a missing phase can cause additional stress on the motor windings and control module, potentially turning a simple wiring repair into a more costly component failure. Leave the machine unpowered until the fault is diagnosed and corrected.
How much does it cost to repair a Fisher & Paykel washer showing E7:02?
Repair costs depend on the root cause. If the fix involves reseating a connector or repairing a wire in the harness, the cost can be relatively low, generally in the range of $50 to $150 for a service call and labor. Replacing the motor can cost between $200 and $450 including parts and labor, while a motor control module replacement typically falls in the $250 to $500 range depending on parts availability and local labor rates.
