Frigidaire Washer Error Code E43 — Control Board Malfunction
What this means
Error codes E43 through E46 indicate an internal malfunction within the main electronic control board. The microprocessor has detected inconsistent signals or a failed component on the board itself. These codes typically require board replacement.
Alternate codes: E44, E45, E46
Step-by-step fix
3 stepsPower cycle the washer
Unplug the washer for 10 minutes, then plug it back in. Sometimes a power surge or electrical glitch can trigger a false E43 code.
Wait the full 10 minutes to allow all capacitors on the board to fully discharge.
Check wiring connections
Remove the top or back panel and inspect all wire harness connections to the main control board. Reseat any loose connectors.
Vibration during spin cycles can gradually loosen connections over time.
Replace the control board
If the error persists after power cycling and reseating connections, the main control board needs replacement.
Photograph all connections before removing the old board to ensure correct installation of the new one.
When to call a professional
Control board replacement is recommended as a professional repair due to the cost of the part and the risk of incorrect installation.
