What 23 means on a Electrolux washer

Error code 23 on an Electrolux washer indicates a drain triac error. The triac is a solid-state switching component located on the main control board that is responsible for controlling power delivery to the drain pump motor. When the control board commands the pump to activate, the triac switches 120 VAC to the pump. If the control detects that the triac has failed in an open or shorted state, or that proper voltage is not reaching the pump, it logs error code 23 and halts the cycle to prevent flooding or component damage.

The diagnostic process for this code begins with two parallel checks: inspecting the drain hose for physical restrictions and verifying that 120 VAC is present at the drain pump during a drain command. A blocked or kinked drain hose can cause excessive back-pressure and prolonged pump run times, which may stress the triac. If voltage is absent at the pump terminals during activation, the triac on the control board is the likely failure point. If voltage is present but the pump does not run, the pump motor itself may be faulty. Both scenarios will produce or contribute to error code 23.

Common causes of 23

  1. 01

    Failed drain triac on control board

    Part replacement

    The triac that switches power to the drain pump can fail in an open or shorted state, preventing the pump from receiving 120 VAC. This requires confirming that voltage is absent at the pump terminals during a drain command before condemning the board.

  2. 02

    Blocked or restricted drain hose

    Wiring / connection

    A kinked, clogged, or improperly routed drain hose prevents water from evacuating, causing extended pump operation and potential control board stress. Inspect the full length of the hose for kinks, clogs, or a standpipe height issue.

  3. 03

    Faulty drain pump motor

    Part replacement

    If 120 VAC is confirmed at the pump terminals but the pump does not run, the pump motor itself has likely failed. A seized or burned pump can also cause current spikes that damage the triac over time.

  4. 04

    Wiring harness fault between control board and pump

    Wiring / connection

    Damaged, corroded, or loose wiring connections in the harness between the control board and the drain pump can interrupt voltage delivery or create intermittent faults. Inspect connector pins and wire insulation for damage or corrosion.

  5. 05

    Clogged pump filter or pump housing

    Wiring / connection

    Debris such as coins, lint, or small garments lodged in the pump filter or pump housing can jam the impeller, causing the motor to stall and triggering the error. Clean the filter and inspect the pump housing for obstructions.

Frequently asked questions about 23

What does 23 mean on a Electrolux washer?
Error code 23 on an Electrolux washer indicates a drain triac error. The triac is a solid-state switching component on the control board that sends 120 VAC to the drain pump. When the control detects a fault in this circuit, it stops the wash cycle and displays code 23. Diagnosis involves checking for drain hose restrictions and confirming voltage at the pump.
Can I fix error code 23 on my Electrolux washer myself?
Some causes of error code 23 are DIY-friendly, such as clearing a blocked drain hose or cleaning the pump filter. However, testing for 120 VAC at the drain pump requires a multimeter and comfort working near live voltage, which may not be appropriate for all homeowners. Replacing the control board due to a failed triac is a more advanced repair best handled by a qualified technician.
Is it safe to keep using my Electrolux washer when error code 23 appears?
It is not recommended to continue running the washer when error code 23 is active. The machine has stopped the cycle because the drain system is not functioning correctly, meaning water may be sitting in the drum. Running additional cycles without addressing the fault could lead to water damage or further component failure.
Will resetting my Electrolux washer clear error code 23?
A reset may temporarily clear the display, but error code 23 will return if the underlying problem is not repaired. If the drain hose is blocked, the pump has failed, or the triac on the control board is defective, the fault will recur as soon as the machine attempts to drain again. The root cause must be identified and corrected to permanently resolve the code.
How much does it cost to repair error code 23 on an Electrolux washer?
Repair costs vary depending on the failed component. Drain pump replacement typically ranges from $80 to $200 including parts and labor. Control board replacement, which addresses a failed triac, generally ranges from $150 to $350 or more depending on the model and technician rates. Clearing a simple hose blockage or pump filter clog may cost little to nothing if done independently.
