Dealing with a Sharp washer E8 error can be frustrating, especially when it interrupts your laundry routine and leaves your clothes locked inside the drum. This specific error code typically indicates a complex technical issue often related to the machine’s internal communication or motor drive system, requiring a systematic approach to diagnose and resolve.
Understanding the Sharp Washer E8 Error
The appearance of the Sharp washer E8 error on your display panel usually signals a communication error between the main components of the appliance. In modern inverter-based washing machines, the Main control board (often referred to as the PCB assembly) must constantly exchange data with the inverter motor to regulate speed, direction, and torque.
When this data exchange is disrupted, the system halts operation to prevent mechanical damage. While the error can sometimes point to a water level sensor issue in older top-loading models, it is most frequently associated with the drive system in front-loading or commercial-grade units.
Common Causes of the E8 Error Code
Identifying the root cause is the first step toward a solution. The following factors are the most frequent culprits behind this malfunction:

1. Wiring Harness and Connection Issues
Over time, the constant vibration of the machine can loosen electrical connections. The wiring harness that connects the main board to the motor may become damaged, or specific connector pins may corrode or unseat, breaking the communication loop.
2. Voltage Fluctuations
Sharp washing machines are sensitive to power instability. Sudden voltage fluctuation or power surges can disrupt the electronic signals within the PCB assembly, triggering a false or temporary E8 error.
3. Faulty Inverter Motor
The inverter motor itself may be the source of the problem. If the motor’s internal sensors fail to send position or speed feedback to the control board, the machine will default to an error state.
4. Main Control Board Failure
If the Main control board is damaged—whether due to moisture exposure, electrical shorts, or component aging—it may fail to process the signals from the motor, resulting in a communication breakdown.
Troubleshooting the Sharp Washer E8 Error
Before calling a professional, there are several troubleshooting steps you can perform safely. Always ensure the machine is unplugged before inspecting any internal components.
Step 1: Perform a Washing Machine Reset
The simplest fix is often a washing machine reset.
- Turn off the washer and unplug it from the power outlet.
- Wait for at least 5 to 10 minutes to allow the electrical capacitors on the PCB assembly to discharge.
- Plug the machine back in and attempt to run a rinse and spin cycle.
- If the error clears, it may have been caused by a temporary glitch or voltage spike.
Step 2: Check Electrical Connections
If the reset does not work, you may need to inspect the wiring.
- Remove the top or back panel of the washer (refer to your service manual for specific instructions).
- Locate the wiring harness running from the motor to the control board.
- Check that all connector pins are securely seated and that there are no visible signs of burnt or frayed wires.
- Disconnect and reconnect the plugs to ensure a clean contact.
Step 3: Inspect the Main Control Board
Visually inspect the Main control board for any signs of damage, such as blackened components or swollen capacitors. If the board appears physically damaged, it will likely need to be replaced.
When to Call an Appliance Repair Technician
If you have performed the basic checks and the Sharp washer E8 error persists, the issue likely lies deep within the electronic components. Diagnosing a faulty inverter motor or reprogramming a new PCB assembly requires specialized tools and knowledge.
Attempting to repair high-voltage electronics without proper training can be dangerous. At this stage, it is recommended to contact a certified appliance repair technician. They have the expertise to test the signal lines correctly and can source the specific parts required for your model.
Conclusion
The Sharp washer E8 error is a protective mechanism designed to alert you to a communication or drive system failure. By understanding the role of the wiring harness, voltage fluctuation, and Main control board, you can effectively troubleshoot the issue. While a simple reset often resolves minor glitches, persistent errors indicate the need for professional service to ensure your washing machine returns to optimal performance.
Frequently Asked Questions
What does the E8 error code mean on a Sharp washing machine?
The E8 error typically signals a communication failure between the appliance’s main control board (PCB assembly) and the inverter motor. It indicates that the system cannot properly exchange the data required to regulate the drum’s speed, direction, and torque.
How do I perform a hard reset to clear the E8 code?
To reset the machine, turn it off and unplug it from the wall outlet for 5 to 10 minutes. This allows the electrical capacitors on the main control board to fully discharge. Afterward, plug the machine back in and attempt to run a rinse and spin cycle to see if the error has cleared.
Can power surges cause an E8 error?
Yes. Sharp washing machines are sensitive to voltage fluctuations. A sudden power surge or unstable electricity can disrupt the electronic signals within the PCB assembly, triggering a temporary E8 error even if there is no permanent mechanical failure.
What should I do if the reset doesn’t work?
If a reset fails, you should inspect the wiring harness for loose connections or damaged pins. However, if the error persists after checking the wires, the issue likely involves a faulty inverter motor or a damaged main control board, which should be handled by a certified appliance repair technician.
