    Why does my LG WM2277HB Washing machine show an imbalance error?
    • P
      Patricia StoneAug 13, 2025
      If your LG Washing machine displays an imbalance error, it could be due to several reasons. The load might be too small, the appliance might be tilted, the laundry might be gathered to one side, or non-distributable items might be in the drum. Try redistributing the load or adjusting the appliance to correct the imbalance.

      mary67Aug 20, 2025
      If your LG Washing machine displays a locked motor error, check the connections to ensure the harness is intact. Specifically, verify that: 1. The connector (3-pin, male, white) in the MOTOR HARNESS is connected to the connector (3-pin, female, white) of STATOR ASSEMBLY. 2. The electric contact between the connectors (3-pin, male, white) in the MOTOR HARNESS and 4-pin, female, white connector in the MAIN PWB ASSEMBLY is good or stable. 3. The MOTOR HARNESS between the STATOR ASSEMBLY and MAIN PWB ASSEMBLY is not cut (open circuited). 4. The hall sensor is not out of order/defective.
