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? +

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.

This is an advanced repair involving deeper disassembly or electrical testing.
