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.
