The error code E SP (sometimes displayed as E:SP or E SP) on your Speed Queen washer indicates a Serial Communication Error (SPI Error). This means the washer's control board is having trouble communicating with another critical component, most likely the motor control board.
Here's a breakdown of what it means, potential causes, and troubleshooting steps
Serial Communication Error (E SP)
The washer's central control board is unable to establish proper communication with the motor control board. This disrupts the flow of information necessary to control the motor and operate the washing cycle.
Possible Causes
- Disconnected Wiring: The electrical wiring harness connecting the control board and motor control board might be loose, disconnected, or damaged.
- Faulty Transformer: In some cases, a faulty transformer that supplies power to the motor control board could be causing the communication issue.
- Malfunctioning Control Board: Less likely, but possible, is a malfunction within the control board itself preventing it from sending or receiving signals properly.
Important Considerations
- Limited User Troubleshooting: Diagnosing and repairing communication errors often involve checking electrical connections and potentially replacing components. For safety reasons, it's best to avoid disassembling the washer yourself.
- Consult a Technician: If you see the E SP error code, contacting a qualified appliance repair technician is highly recommended. They have the expertise and tools to diagnose the problem (loose wiring, faulty transformer, or control board issue) and perform the necessary repairs.
Troubleshooting Steps
- Reset the Washer (Optional): You can try a simple reset by unplugging the washer for a minute and then plugging it back in. This can sometimes clear temporary glitches that might be causing the error. However, a communication error is likely a hardware issue, and a reset is unlikely to fix it permanently.
Safety Reminder: Remember, communication errors involve electrical components. Leave the diagnosis and repair to a qualified appliance repair technician to ensure safety and proper repairs.
