Frequently Asked Questions

Can I keep using my Electrolux Dryer when error E40 appears? +
You often can for a cycle or two, but the door issue behind E40 will keep interrupting normal operation until it is fixed. Plan the repair rather than ignoring the code.

E40 keeps coming back after a reset — what should I check next? +
A reset only clears the stored E40 fault; if it returns, the door problem is still present.

This is a moderate job — a multimeter and some disassembly are usually involved.
