GE Washer Error Code E46

Drive motor over temperature

GE codesGE washer codes

Drive motor over temperature - inverter over temperature (heat sink).

First step from the service manual

Check motor using t10, t11, t14. Power down washer, wait 30 seconds and retry using whites cycle sanitize temperature - if reoccurs, replace drive motor.

What E46 means on a GE washer

The E46 error code on a GE washer indicates that the drive motor or its associated inverter has reached an unsafe operating temperature. Specifically, this code points to overheating at the inverter heat sink, which is the component responsible for dissipating thermal energy generated by the inverter board as it controls motor speed and torque. When the heat sink temperature exceeds safe thresholds, the control system triggers this fault to prevent damage to the motor and inverter electronics.

The inverter converts DC voltage into variable-frequency AC power to drive the wash motor. During normal operation, the heat sink absorbs and radiates heat away from the inverter's power transistors. If airflow around the inverter is blocked, if the motor is working harder than normal due to mechanical resistance, or if the motor itself is failing internally, heat buildup can occur rapidly. Diagnostic tests T10, T11, and T14 are used to evaluate motor performance and electrical integrity to help isolate whether the motor or the inverter is the root cause.

In many cases, the fault may be temporary, caused by an unusually heavy load or a brief ventilation restriction. Powering down the washer and waiting 30 seconds allows the heat sink to cool before retrying. The recommended retry cycle is the Whites cycle at sanitize temperature, which provides a controlled load condition for observing whether the fault returns. If E46 reappears after the reset and retry, the drive motor is the indicated replacement component.

Common causes of E46

  1. 01

    Failing or degraded drive motor

    Part replacement

    A motor with worn windings or failing bearings draws excessive current, generating more heat than the inverter heat sink can dissipate. If E46 returns after a cool-down and retry, the drive motor is the primary suspect.

  2. 02

    Inverter heat sink overheating

    Wiring / connection

    The inverter heat sink can overheat if airflow around the inverter board is blocked by debris, lint buildup, or improper installation. Inspect the area around the inverter for obstructions before replacing components.

  3. 03

    Excessive or unbalanced load

    Wiring / connection

    Overloading the washer or running repeated heavy cycles back to back can cause the motor and inverter to overheat temporarily. Reducing load size and allowing a cool-down period often resolves the issue in these cases.

  4. 04

    Mechanical resistance in the drive system

    Part replacement

    A worn bearing, seized drum support, or obstruction in the wash basket forces the motor to work harder than intended, increasing heat output. Check for unusual noise or drum drag during manual rotation.

  5. 05

    Inverter board fault

    Part replacement

    If the inverter board itself is malfunctioning, it may be generating excess heat or misreading temperature sensor signals. Diagnostic tests T10, T11, and T14 can help evaluate whether the motor or the inverter board is responsible.

Frequently asked questions about E46

What does E46 mean on a GE washer?
E46 indicates that the drive motor or the inverter heat sink has exceeded safe operating temperatures. The inverter controls the motor speed and generates heat during operation, and this code triggers when that heat reaches a critical level. The washer shuts down to protect the motor and inverter electronics from damage.
Can I fix E46 myself or do I need a technician?
You can start by powering down the washer, waiting 30 seconds, and retrying with the Whites cycle at sanitize temperature. If the error clears and does not return, no repair may be needed. If E46 reoccurs, replacing the drive motor is the indicated fix, which is a more involved repair that may be best handled by a technician depending on your comfort level with appliance disassembly.
Is it safe to use my GE washer when E46 is showing?
No, you should not continue running the washer while E46 is active. The code indicates the motor or inverter is overheating, and running the machine in this condition risks damaging the inverter board or drive motor further. Allow the unit to cool completely before attempting the recommended reset and retry procedure.
Will resetting the washer clear the E46 error?
A power-down reset of 30 seconds may clear E46 if the overheating was caused by a temporary condition such as a heavy load or brief airflow restriction. However, if the underlying cause is a failing drive motor, the error will return during the retry cycle. A reset alone does not fix the root cause when a component is at fault.
How much does it cost to repair a GE washer showing E46?
If the issue is a failing drive motor, parts and labor typically range from around $150 to $400 or more depending on the specific model and local labor rates. If the inverter board is the cause, costs can be similar or higher. A diagnostic visit from a technician to confirm the fault before ordering parts is usually recommended.
