What E5E means on a Frigidaire washer

The E5E error code on a Frigidaire washer indicates a communication failure between the main control board and the speed control board. These two boards work together to regulate motor operation: the main control board sends commands regarding wash cycle speed and direction, while the speed control board interprets those signals and drives the motor accordingly. When the communication link between them is interrupted or corrupted, the washer cannot safely operate the motor and will display E5E to alert the technician to the fault.

The communication between these boards typically travels through a wiring harness connecting the two components. Any break, short, loose connector, or corroded terminal in this harness can disrupt the signal and trigger the error. This is why the first diagnostic step is a thorough inspection of the wiring between the control board and the speed control board, as outlined in test 11 of the diagnostic procedure. Connector pins that have backed out of their housing or wires that have chafed against the cabinet are common physical causes found during inspection.

If the wiring harness checks out as intact and properly seated, the fault likely lies within one of the two boards themselves. Either the main control board has failed to transmit the communication signal correctly, or the speed control board has lost its ability to receive and process it. In some cases, a power surge or voltage irregularity can damage the communication circuits on either board. Identifying which board is at fault typically requires substitution testing or further board-level diagnostics beyond the initial wiring inspection.

Common causes of E5E

  1. 01

    Loose or disconnected wiring harness connector

    Wiring / connection

    The connector joining the main control board to the speed control board may have worked loose due to vibration. Inspect both ends of the harness for connectors that are not fully seated or have backed-out pins.

  2. 02

    Damaged or chafed wiring between boards

    Part replacement

    Wires in the harness can rub against sharp cabinet edges or moving components, causing insulation wear and short circuits. Trace the full length of the wiring between both boards and look for visible damage or bare conductors.

  3. 03

    Corroded connector terminals

    Wiring / connection

    Moisture exposure inside the washer cabinet can cause oxidation on the harness connector terminals, increasing resistance and breaking the communication signal. Look for green or white corrosion buildup on the pins and sockets.

  4. 04

    Failed speed control board

    Part replacement

    If the wiring harness is intact and connections are secure, the speed control board itself may have failed and lost the ability to receive or process signals from the main control board. Board replacement is required if diagnostics confirm this.

  5. 05

    Failed main control board

    Part replacement

    Less commonly, the main control board may have developed a fault in the circuit responsible for transmitting communication signals to the speed control board. This is typically ruled out after the wiring and speed control board have been cleared as causes.

Frequently asked questions about E5E

What does E5E mean on a Frigidaire washer?
E5E indicates a communication problem between the main control board and the speed control board. These two boards must exchange signals to control motor speed and direction during a wash cycle. When that communication link breaks down, the washer displays E5E and stops operating to prevent damage. The fault can stem from wiring issues or a failure in one of the two boards.
Can I fix the E5E error code myself?
A knowledgeable DIYer can start by inspecting the wiring harness between the two control boards for loose connectors, damaged wires, or corroded terminals, as these are the most common causes. Reseating connectors or repairing a chafed wire is within reach for someone comfortable working with appliance wiring. However, if the fault lies in a failed control board, sourcing and replacing the correct board requires more technical confidence and the right part.
Is it safe to use my Frigidaire washer while the E5E code is active?
You should not attempt to run the washer while E5E is displayed. The error means the motor cannot be properly controlled, which could result in unpredictable operation or further damage to internal components. Wait until the fault is diagnosed and repaired before running a cycle.
Will resetting my Frigidaire washer clear the E5E error?
A reset may temporarily clear the code, but E5E will return if the underlying communication fault has not been corrected. If a loose connector caused a momentary loss of communication, reseating it and resetting the machine may resolve the issue. In most cases though, a reset alone is not a fix, and the wiring and boards should be properly inspected.
How much does it cost to repair the E5E error on a Frigidaire washer?
Repair costs vary depending on the root cause. If only a wiring repair or connector cleaning is needed, costs are typically low, often in the range of $50 to $150 for a service call. If a speed control board or main control board needs replacement, parts and labor combined can range from $150 to $400 or more depending on the specific model and local labor rates.
