What Does Error Code E43 Mean on a Frigidaire Washing Machine?

Control board communications fault.

E43 fires when the main control board detects an internal communications failure between its own processing sections and cannot coordinate the wash cycle. Unlike sensor or motor codes that point to an external part, E43 indicates the board's internal logic or inter-section link has faulted. Loose connectors or harnesses between board sections can mimic this, and power surges or moisture intrusion can corrupt the board. Related codes E44 and E5E involve similar control-side communication faults but distinct circuits.

Models affected: Frigidaire front-load and top-load washers with electronic control boards, roughly mid-2000s onward

What owners report: Owners commonly report E43 appearing suddenly mid-cycle or right after power-up, sometimes following a storm or power blip. A quick win many mention is unplugging the machine for several minutes, which occasionally clears a one-time glitch; if it returns quickly, the board itself is usually the culprit.

Frequently Asked Questions

Can I keep using my Frigidaire 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 Frigidaire Washing Machine? +

Across reported Frigidaire washing machine repairs, the most frequent is main control board internal communications failure (70% of cases), connector/harness between board sections loose (20%), then power surge or moisture damage to the board (10%). Check them in that order before replacing any parts.

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. Move on to the physical checks — power cycle, then reseat board connectors — 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 E43? +

A DIY repair typically runs $100–$280 in parts, versus $200–$420 for a professional service call, so handling it yourself saves around $100. Expect the work to take 1–3 hours.

Which Frigidaire Washing Machine models show error E43? +

E43 is documented on Frigidaire front-load and top-load washers with electronic control boards, roughly mid-2000s onward. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
