What Does Error Code E43 Mean on a Electrolux Washing Machine?

Door lock triac failure on the control board.

E43 fires when the control board's self-diagnostics detect that the triac driving the door-lock circuit has failed. The board cannot switch power to the lock, so the door won't secure and no cycle can begin, even when the lock assembly itself tests good. This distinguishes it from lock-mechanism codes like E42 (lock not confirmed) and E45, which point to wiring or the lock unit rather than the board's switching component. Power surges commonly damage this triac.

Models affected: Electrolux front-load washers with electronic control boards, including models such as EFLS627UTT and ELFW7637AT

What owners report: Owners commonly report E43 appearing suddenly, often after a storm or power fluctuation, with the door refusing to lock and the cycle stalling at the start. A 10-minute unplug occasionally clears a transient, but when the code returns most owners find the control board needs replacing rather than the lock itself.

Frequently Asked Questions

Can I keep using my Electrolux Washing Machine when error E43 appears? +

It is not advisable. The washing machine may still power on, but running it while E43 is active can worsen the control-board fault or damage related parts. Treat it as a soon-as-possible repair.

What most commonly causes E43 on a Electrolux Washing Machine? +

Across reported Electrolux washing machine repairs, the most frequent is door lock triac on control board failed (60% of cases), power surge damaging the triac (25%), then control board general fault (15%). Check them in that order before replacing any parts.

E43 keeps coming back after a reset — what should I check next? +

A reset only clears the stored E43 fault; if it returns, the control-board problem is still present. Move on to the physical checks — reset the washer, then verify the door lock is good — since the code will reappear until the root cause is resolved. This is an advanced repair involving deeper disassembly or electrical testing.

How much does it cost to fix Electrolux Washing Machine error E43? +

A DIY repair typically runs $120–$280 in parts, versus $200–$450 for a professional service call, so handling it yourself saves around $80. Expect the work to take 1–3 hours.

Which Electrolux Washing Machine models show error E43? +
