What E24 means on a Electrolux washer

The E24 error code on an Electrolux washer indicates a malfunction in the sensing circuit on the triac responsible for controlling the drain pump. A triac is a bidirectional semiconductor switching device used on the main control board to regulate power delivery to the drain pump motor. The microprocessor monitors the triac's switching behavior by reading feedback voltage from the sensing circuit. When the voltage returning to the microprocessor falls outside the expected range, the board interprets this as a sensing circuit fault and triggers E24.

The root cause is most commonly a failure within the main circuit board itself, either in the triac component, the associated gate resistors, or the feedback sensing loop. Because the sensing circuit is integrated into the board's design, individual component-level repair is generally not practical. The wrong input voltage reaching the microprocessor can result from a shorted or open triac, degraded solder joints on the board, or moisture-related corrosion on the control circuitry.

Because the first diagnostic step for E24 is direct replacement of the main circuit board, technicians should visually inspect the board for burn marks, swollen capacitors, or corrosion before ordering a replacement. It is also worth verifying that the wiring harness connecting the board to the drain pump is intact and free of shorts, since an external wiring fault could stress the triac circuit and produce the same error condition.

Common causes of E24

  1. 01

    Failed main control board triac

    Part replacement

    The triac on the control board that switches power to the drain pump can fail in a shorted or open state, sending incorrect voltage back to the microprocessor. This is the most likely cause and typically requires full board replacement.

  2. 02

    Damaged or degraded sensing circuit on the control board

    Part replacement

    Resistors, traces, or other components in the feedback sensing loop on the main board can degrade over time, causing the microprocessor to read incorrect input voltage. Visual inspection may reveal burn marks or corroded solder joints.

  3. 03

    Wiring harness fault between board and drain pump

    Wiring / connection

    A short circuit or broken wire in the harness connecting the control board to the drain pump can place abnormal load on the triac circuit and trigger the sensing fault. Inspect the harness for pinched, melted, or corroded wiring.

  4. 04

    Moisture or corrosion on the control board

    Part replacement

    Water intrusion near the control board can cause corrosion on the triac sensing circuitry, leading to erratic or incorrect voltage readings at the microprocessor. Look for white residue or discoloration on the board surface.

Frequently asked questions about E24

What does E24 mean on a Electrolux washer?
E24 indicates a malfunction in the sensing circuit on the triac that controls the drain pump, resulting in wrong input voltage being received by the microprocessor. The triac is a switching component located on the main control board. This fault signals that the board is not properly monitoring or controlling the drain pump circuit. In most cases, replacing the main control board is the required repair.
Can I fix an E24 error on my Electrolux washer myself?
If you are comfortable working with appliance electronics, you can replace the main control board yourself after disconnecting power to the unit. The repair involves removing the board, disconnecting the wiring harnesses, and installing the replacement. It is also worth inspecting the drain pump wiring harness for visible damage before committing to a board replacement. Always disconnect the washer from power before performing any internal work.
Will resetting my Electrolux washer clear the E24 error?
A reset may temporarily clear the E24 code, but it will return if the underlying fault in the triac sensing circuit is still present. You can attempt a reset by unplugging the washer for a few minutes and then restoring power. If the code comes back immediately or during the next drain cycle, board replacement is necessary. A reset alone does not repair a failed triac or damaged sensing circuit.
Is it safe to use my Electrolux washer when it shows E24?
It is not recommended to continue running the washer with an active E24 error. Because the fault involves the circuit that controls the drain pump, the washer may be unable to drain properly, which could lead to water sitting in the drum or potential overflow conditions. Continued use with a faulty triac circuit could also worsen damage to the control board. Have the unit inspected and repaired before resuming normal laundry cycles.
How much does it cost to repair an E24 error on an Electrolux washer?
The cost of repair depends on whether you hire a technician or perform the repair yourself. A replacement main control board for an Electrolux washer typically ranges from around $100 to $300 or more depending on the specific model. If you use a professional repair service, labor costs can add another $80 to $200 to the total. DIY replacement is the most cost-effective option if you are comfortable with the procedure.
