Little Swan After-sales Service Case: XQB40-868FC(G) Washing Machine Cannot Wash
Fault Symptoms: After turning on the washing machine, it cannot perform the wash cycle.
Inspection and Judgment: This fault usually occurs in either the mechanical system or the electrical system. First, the mechanical system was checked and found to be normal, which indicates that the fault lies in the electrical system. Measurements showed that the forward and reverse rotation signals from the computer board were normal. Components related to the bidirectional thyristors TR2, TR4, as well as C7, C16, R25, C9, C13, R24 were all checked and found to be without abnormality. The motor drive belt was also inspected and no slipping was detected. The engagement of the clutch gear was normal. Further inspection of the motor windings resistance and the motor start capacitor revealed that the start capacitor had a severe leakage problem.
Resolution Method: After replacing the start capacitor with one of the same model, the machine was tested. The fault was resolved. (LG Washing Machine Repair, Beijing Whirlpool Washing Machine Repair Phone Number).
