Speed Queen Washer Error Code FINAL SPIN/RINSE LEDs Flashing

SPI communications error

Speed Queen codesSpeed Queen washer codes

SPI communications error – problem with communications between the front-end control and the motor control; all outputs are turned off.

First step from the service manual

Check fuse on motor control board (tighten holder and/or replace fuse). Check voltage across H1-1 and H1-3 on motor control board and H6-5 and H6-6 on machine control. Machine must be powered down to clear.

What FINAL SPIN/RINSE LEDs Flashing means on a Speed Queen washer

The FINAL SPIN/RINSE LEDs flashing simultaneously on a Speed Queen washer indicates an SPI (Serial Peripheral Interface) communications error. This fault means the front-end control board and the motor control board have lost the ability to communicate with each other over the SPI data bus. When this condition is detected, the washer shuts down all outputs as a protective measure, halting the motor, valve solenoids, and any other active components until the communication link is restored.

The SPI communication link between the two control boards relies on stable voltage and a clean signal path. Diagnostic focus starts at the fuse on the motor control board, as a blown or loose fuse is one of the most common triggers for this fault. Technicians should check the fuse holder for tightness and replace the fuse if open. After addressing the fuse, voltage should be measured across terminals H1-1 and H1-3 on the motor control board and across terminals H6-5 and H6-6 on the machine control board to confirm proper supply levels are reaching both boards.

If voltage and fuse checks pass, the fault may point to a failed motor control board, a failed front-end control board, or a damaged wiring harness connecting the two. Connector corrosion, broken wires, or a harness that has chafed against a cabinet edge can interrupt the SPI signal without causing a visible blown fuse. This error code requires a full power-down cycle to clear and will not reset while the machine remains energized.

Common causes of FINAL SPIN/RINSE LEDs Flashing

  1. 01

    Blown or loose fuse on motor control board

    Part replacement

    A blown fuse or a fuse sitting loosely in its holder on the motor control board will interrupt power to that board and break SPI communication. Inspect the fuse holder for tightness and test the fuse for continuity before replacing.

  2. 02

    Incorrect or missing voltage at motor control board

    Wiring / connection

    If voltage measured across terminals H1-1 and H1-3 on the motor control board is absent or out of spec, the board cannot maintain communication. This may indicate a wiring issue, a failed power supply circuit, or a problem upstream of the board.

  3. 03

    Incorrect or missing voltage at machine control board

    Wiring / connection

    Low or absent voltage at terminals H6-5 and H6-6 on the machine control board can prevent the front-end control from sustaining SPI communication. Check these terminals with the machine powered and the fault present.

  4. 04

    Damaged or corroded wiring harness between control boards

    Part replacement

    A harness connector that is corroded, unplugged, or has chafed wiring can break the SPI data path between the two boards. Inspect the full harness run for wear, pinching against the cabinet, or loose connector seats.

  5. 05

    Failed motor control board or front-end control board

    Part replacement

    If fuse, voltage, and wiring checks all pass, one of the two control boards may have an internal failure preventing SPI communication. Board replacement is typically the final step after all other causes are ruled out.

Frequently asked questions about FINAL SPIN/RINSE LEDs Flashing

What does FINAL SPIN/RINSE LEDs Flashing mean on a Speed Queen washer?
When the FINAL SPIN and RINSE LEDs flash together, the washer is signaling an SPI communications error between the front-end control board and the motor control board. The machine shuts off all outputs when this fault occurs to protect components. The most common starting points for diagnosis are the fuse on the motor control board and the supply voltage at specific terminals on both control boards. The washer must be fully powered down to clear this error.
Can I reset this error code by unplugging my Speed Queen washer?
Powering down the machine is required to clear this error, but unplugging alone will not fix the underlying problem. If the root cause, such as a blown fuse or a wiring fault, is not corrected first, the error will return as soon as the washer attempts to operate. A full repair of the communication fault must be completed before the machine will run reliably.
Is it safe to keep using my washer while this error is active?
No. When this fault is detected, the washer shuts off all outputs, meaning the machine will not run a cycle anyway. Attempting repeated restarts without diagnosing the cause could stress the control boards further. The washer should be left unpowered until the fault is properly diagnosed and repaired.
How much does it cost to repair the SPI communications error on a Speed Queen washer?
Repair costs vary depending on the root cause. If only a fuse needs replacement, the part cost is minimal, though a service call will still apply. If a motor control board or front-end control board requires replacement, parts and labor together typically range from $150 to $450 or more depending on your location and the specific boards involved. Getting an accurate diagnosis before ordering parts helps avoid unnecessary expense.
How do I diagnose the SPI communications error on a Speed Queen washer?
Start by inspecting the fuse on the motor control board: tighten the fuse holder and replace the fuse if it tests open. Next, measure voltage across terminals H1-1 and H1-3 on the motor control board and across terminals H6-5 and H6-6 on the machine control board to confirm proper supply levels. If both voltage checks and the fuse pass, inspect the wiring harness between the two boards for damage, corrosion, or loose connectors. If all wiring and power checks are good, one or both control boards may need to be replaced.
