GE Washer Error Code E64

The E64 error code on a GE washer indicates that the control board detected an unexpected open door condition while a wash cycle was actively running. This means the door lock assembly reported an unlatched or open state at a point in the cycle when the door should be secured. The door lock system on these machines uses a combination of switches and a solenoid to both physically latch the door and send confirmation signals back to the main control board. When those signals become inconsistent or drop out entirely during operation, the control interprets this as a switch failure and halts the cycle.

The most common hardware involved in this fault is the door lock assembly itself, which contains multiple internal switches that confirm latch position, and a solenoid that engages the locking mechanism. If any of these switches develop an open circuit, stick, or fail to close reliably, the control board will log E64. Wiring between the door lock and the main control board is equally suspect, as broken wires, corroded terminals, or loose connectors can produce intermittent open-circuit readings that the board misreads as a door fault.

Diagnosis should begin with a power cycle: unplug the machine for 30 seconds, then restart. If E64 returns, physically inspect the wiring harness and connector at both the door lock and the control board for damage or loose pins. Test the door lock switches and solenoid for continuity and correct resistance. If all wiring and lock components test within acceptable parameters and the fault persists, the main control board is the likely culprit and should be replaced.
