Affected model seriesEFLS617SIW, EFLS517SIW, EFLS417SIW
Quick answer
Electrolux washer code E43 indicates door lock triac control failure.
Model compatibility: Electrolux reuses codes across series and control generations, so E43 may mean something different on another appliance or platform. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
When E43 appears on your Electrolux washer, it indicates door lock triac control failure. A careful first check can rule out simple causes without opening the washer. Do not replace parts from the code alone; use the full model number and the observed symptoms to confirm the cause.
The practical value of this code is that it narrows the next check: door lock triac control failure. Do not choose a replacement part from the display alone; door-lock device problem and lock wiring issue can produce overlapping symptoms.
This record is based on the Electrolux technical/service documentation for the EFLS617SIW, EFLS517SIW, and EFLS417SIW control generation. The same display code can have a different meaning on another Electrolux platform, so confirm the full model number before applying this diagnostic path.

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Check that the door is fully closed and nothing is trapped in the opening.
Inspect only the visible latch area for debris or physical damage.
Power the washer off for several minutes and retry once.
If the code returns, avoid repeated start attempts because the lock/control circuit needs testing.
Important safety warning. Stop user-level troubleshooting if the code returns after one safe reset/check cycle or if the washer shows leaking, overheating, electrical, or mechanical symptoms.

When to call a technician
Book service if E43 returns after a power reset. This code can involve internal wiring, controls, sensors, relays, pumps, or motor electronics that should be tested with the appliance made electrically safe.
When booking for E43, note the full model number and whether door may not lock or unlock normally. A model-specific diagnosis can then concentrate on door-lock device problem without replacing parts by guesswork.

It indicates door lock triac control failure. Confirm the full washer model because diagnostic meanings can vary between control platforms.
You can try the safe external checks listed above and one power reset where appropriate. If the code returns, repeated resets are not a substitute for diagnosis.
Avoid continued use if there is leaking, overheating, an electrical symptom, a locked door, or abnormal drum movement. Otherwise, correct any simple installation or load issue and test once.
