Haier Washer Error Code FA — Communication/Water Level Sensor Fault
What this means
Error code FA on Haier washers can indicate two related issues: a communication failure between the main power board and the display/user interface board, or a water level sensor circuit problem. On some Haier models, FA specifically refers to the pressure transducer circuit failure. The washer will not operate until this fault is resolved. Causes include a loose or corroded ribbon cable between boards, a failed pressure transducer, or a faulty main board.
Alternate codes: fA
Step-by-step fix
3 stepsPower-cycle the washer
Unplug the washer for 2 minutes. This forces a complete reset of both the power board and the display board. Plug back in and check if FA has cleared.
Power surges and electrical storms commonly cause temporary FA errors that clear after a reset.
Reseat board-to-board connections
Unplug the washer and open the control panel housing. Locate the ribbon cable or wire harness connecting the main board to the display board. Disconnect, spray connectors with electronic contact cleaner, and firmly reseat.
Vibration from the washer can gradually loosen board connectors over time.
Check the water level sensor/transducer
If FA persists, locate the water level sensor (pressure transducer). Disconnect its wiring and test for continuity. Check the air tube connected to it for blockages or disconnections.
Some Haier models use an electronic pressure transducer instead of a mechanical switch — these cannot be tested by blowing into the tube.
When to call a professional
FA errors that persist after reseating connectors and checking the transducer typically indicate a failed main board or display board. Service is required for board replacement.
