What Does Error Code E42 Mean on a Frigidaire Washing Machine?

Door will not unlock at the end of the cycle.

The control could not release the door lock when the cycle ended. It is most often caused by water still in the tub (the safety logic keeps the door locked until drained), or by a sticking lock mechanism.

Frequently Asked Questions

Can I keep using my Frigidaire Washing Machine when error E42 appears? +
You often can for a cycle or two, but the door issue behind E42 will keep interrupting normal operation until it is fixed. Plan the repair rather than ignoring the code.
What most commonly causes E42 on a Frigidaire Washing Machine? +
Across reported Frigidaire washing machine repairs, the most frequent is water not fully drained, keeping the door locked (40% of cases), door lock mechanism sticking / not releasing (30%), then clogged drain filter or weak drain pump (20%). Check them in that order before replacing any parts.
E42 keeps coming back after a reset — what should I check next? +
A reset only clears the stored E42 fault; if it returns, the door problem is still present. Move on to the physical checks — confirm the tub is empty, then power reset — since the code will reappear until the root cause is resolved. This is a moderate job — a multimeter and some disassembly are usually involved.
How much does it cost to fix Frigidaire Washing Machine error E42? +
