What Does Error Code E45 Mean on a Frigidaire Washing Machine?

Door lock control board failure.

E45 fires when the main control board's communication with the door lock circuit board fails or returns invalid data, meaning the board cannot verify or command the lock state. Unlike E41 (door lock not detected) or E42 (door remains unlocked), E45 points to the lock control electronics or its wiring rather than a stuck latch or open door. The board detects the fault before the wash cycle can safely proceed and halts operation.

Models affected: Frigidaire front-load washers with an electronic door lock circuit, common on models with E4x fault-code series
What owners report: Owners commonly report E45 appearing at the start of a cycle when the door won't lock or the machine refuses to run. A power cycle sometimes clears it temporarily if the trigger was a transient glitch, but a returning code usually points to the lock assembly or a chafed wiring harness connector.

Frequently Asked Questions

Can I keep using my Frigidaire Washing Machine when error E45 appears? +
You often can for a cycle or two, but the control-board issue behind E45 will keep interrupting normal operation until it is fixed. Plan the repair rather than ignoring the code.
What most commonly causes E45 on a Frigidaire Washing Machine? +
Across reported Frigidaire washing machine repairs, the most frequent is door lock circuit board failure (65% of cases), wiring harness fault (25%), then main control board door lock relay (10%). Check them in that order before replacing any parts.
E45 keeps coming back after a reset — what should I check next? +
A reset only clears the stored E45 fault; if it returns, the control-board problem is still present. Move on to the physical checks — power cycle, then test door lock assembly — 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 Frigidaire Washing Machine error E45? +
A DIY repair typically runs $40–$280 in parts, versus $200–$420 for a professional service call, so handling it yourself saves around $160. Expect the work to take 1–3 hours.
Which Frigidaire Washing Machine models show error E45? +
E45 is documented on Frigidaire front-load washers with an electronic door lock circuit, common on models with E4x fault-code series. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
