AEG Washer Error Code E8

E8 indicates a fault in the motor circuit or motor control system. The code covers several possible causes including a tachogenerator short or open circuit, a motor winding fault, a blocked motor, a defective cable between the motor board and the main board, or a failed MOS-FET transistor on the DC electronics board. The washer cannot determine drum speed reliably when any of these faults are present, so it halts operation and displays the code.

No, you should not continue running the washer while E8 is active. The error indicates a motor or motor control fault, and operating the machine in this state could cause additional damage to the motor, control boards, or wiring. Unplug the machine and diagnose the fault before attempting to run another cycle.

A reset may temporarily clear the error code display, but E8 will return as soon as the washer attempts to run a cycle if the underlying fault is still present. The tachogenerator, motor, wiring, or electronics board issue must be diagnosed and corrected to permanently resolve the error. Repeated resets without addressing the root cause can risk further damage to connected components.

Some causes of E8 are DIY-friendly. Checking for and clearing a drum blockage requires no tools beyond unplugging the machine and manually turning the drum. Inspecting the motor wiring harness for obvious damage or loose connectors is also straightforward. However, replacing the tachogenerator, motor, or DC electronics board involves working with high-voltage components and is best handled by a qualified technician if you are not comfortable with appliance repair.

Repair costs vary depending on the faulty component. Clearing a mechanical blockage costs nothing beyond your time. A replacement tachogenerator or wiring harness typically falls in the range of $20 to $80 for parts. A new motor or DC electronics board can range from $100 to $300 or more for parts alone, with labor adding to the total if a technician is needed.
