Fault inspection: Refer to the electrical principle circuit diagram of this washing machine, and it is found that the program controller fails to work properly. The possible reasons could be faults in the synchronous micro-motor inside the program controller or poor contact between the touch piece and internal assembly, causing the paddle to always rotate in one direction. This is because the cam touch piece controlling the positive and reverse rotation inside the program controller is closed, possibly due to sparking which causes the contacts to stick together. Replace the program controller, start the machine for testing, the washing machine works normally, and the fault is eliminated.
