Fisher & Paykel Dishwasher Error Code E2

Motor fault

Fisher & Paykel codesFisher & Paykel dishwasher codes

Motor fault – motor not rotating, drawing too much current, or not drawing enough current (sub codes 01, 02, 03).

First step from the service manual

Check that the hall sensor/RPS is correctly installed and held firmly in place. Check the harness connections at the motor and controller for signs of water damage, corrosion or arcing.

What E2 means on a Fisher & Paykel dishwasher

The E2 error code on a Fisher & Paykel dishwasher indicates a motor fault, specifically a condition where the wash motor is not rotating, is drawing excessive current, or is drawing insufficient current. The three sub codes refine the diagnosis: sub code 01 points to the motor not rotating at all, sub code 02 indicates the motor is pulling too much current (suggesting a mechanical blockage or winding fault), and sub code 03 indicates the motor is drawing too little current (suggesting an open circuit or failed winding). The wash motor is responsible for circulating water through the spray arms during the wash cycle, so any fault in its operation will halt the cycle.

The hall sensor, also called the rotor position sensor (RPS), plays a critical role in motor control. This sensor monitors the motor's rotor position and feeds rotation data back to the controller. If the sensor is loose, misaligned, or has a damaged harness connection, the controller may incorrectly determine that the motor has stalled or failed, triggering E2 even if the motor itself is mechanically sound. Harness connections at both the motor and controller are common failure points, particularly if water ingress has caused corrosion or arcing at the connector pins.

Mechanical causes such as a jammed impeller or seized motor bearings can also produce this fault, particularly sub code 02 where high current draw points to the motor working against a physical obstruction. A failed motor winding or a faulty motor control board can produce sub code 03, where the circuit appears open. Systematic diagnosis should begin at the hall sensor installation and connector integrity before moving to motor resistance testing or controller evaluation.

Common causes of E2

  1. 01

    Loose or misaligned hall sensor (RPS)

    Wiring / connection

    The hall sensor must be firmly seated and correctly positioned to accurately report motor rotation to the controller. If it has shifted or is not fully secured, the controller may register a stall or incorrect current condition even when the motor is functional.

  2. 02

    Corroded or damaged harness connectors

    Wiring / connection

    Water intrusion at the motor harness or controller connector can cause corrosion, arcing, or intermittent open circuits that disrupt the motor control signals. Inspect both connector ends for discoloration, pitting, or melted plastic.

  3. 03

    Jammed or blocked impeller

    Wiring / connection

    Debris such as broken glass, food particles, or a dislodged component can mechanically block the pump impeller, causing the motor to draw excessive current and triggering sub code 02. Removing the pump cover and clearing any obstruction may resolve this without part replacement.

  4. 04

    Failed wash motor

    Part replacement

    A motor with shorted or open windings will produce abnormal current readings, corresponding to sub codes 02 or 03 respectively. If harness and sensor checks are clear, the motor itself may need to be tested for winding continuity and replaced if faulty.

  5. 05

    Faulty motor control board

    Part replacement

    If the controller is not delivering correct voltage or drive signals to the motor, the motor will not operate normally and E2 will be triggered. This is typically diagnosed after the motor and all wiring have been ruled out as the source of the fault.

Frequently asked questions about E2

What does E2 mean on a Fisher & Paykel dishwasher?
E2 indicates a motor fault where the wash motor is either not rotating, drawing too much current, or drawing too little current. There are three sub codes (01, 02, 03) that identify which specific condition is present. The motor is responsible for circulating water through the dishwasher during the wash cycle, so this fault will prevent the appliance from completing a cycle. Diagnosis should start with the hall sensor installation and harness connections before moving to the motor or controller.
Can I fix an E2 error on my Fisher & Paykel dishwasher myself?
Some causes of E2 are DIY-accessible, particularly checking that the hall sensor is correctly seated, inspecting harness connectors for corrosion, and clearing any debris from the pump impeller. These steps require basic mechanical confidence and safe disconnection of power before opening the machine. If the fault points to a failed motor or control board, replacement of those components typically requires more advanced skills and appropriate tools.
Is it safe to keep using my dishwasher when it shows E2?
No, you should not continue running the dishwasher with an active E2 fault. The motor fault means water is not circulating correctly, and if the motor is drawing excessive current, there is a risk of overheating in the motor or wiring. Discontinue use until the fault is diagnosed and repaired.
Will resetting the dishwasher clear the E2 error?
A reset may temporarily clear the error code display, but if the underlying fault in the motor, hall sensor, or wiring is still present, the E2 code will return as soon as the dishwasher attempts to run the motor again. A reset is useful for confirming whether a fault is persistent or intermittent, but it does not fix the root cause.
How much does it cost to repair an E2 error on a Fisher & Paykel dishwasher?
Repair costs vary depending on the root cause. If the fix involves reseating the hall sensor or cleaning corroded connectors, costs may be minimal, primarily covering a service call in the range of $80 to $150. Replacing the wash motor typically brings total repair costs to between $200 and $450 including parts and labor. A control board replacement can push costs higher, often in the $300 to $600 range, at which point evaluating the age and overall condition of the appliance is worthwhile.
