Abstract

The invention discloses a fault diagnosing and repairing method for a washing machine. The fault diagnosing and repairing method includes the steps of monitoring a washing progress, a loading state and a motor operation state of the washing machine in real time; if fault information is detected, judging a fault type according to the motor operation state; repairing the washing machine according to the fault type and the washing progress and the loading state of the washing machine when the washing machine breaks down; judging whether the fault is a hardware fault according to a repair result; if yes, performing fault alarming; if not, continuously operating the washing progress when the washing machine breaks down after repairing. The fault diagnosing and repairing method for the washing machine has the advantages that judgment fault probability can be lowered, and a repair rate of the washing machine can be lowered.

Description

technical field [0001] The invention belongs to the technical field of electric appliance manufacturing, and in particular relates to a washing machine fault diagnosis and repair method. Background technique [0002] The washing machine provides great convenience for people's life. Generally, the washing machine includes a cabinet, a machine door, a water tank, a clothes tank and a control system. The door is located on the top surface of the cabinet for opening and closing. And the suspension mechanism is fixed in the box, the clothes drum is installed inside the water tank, the motor and the clothes drum are driven by belts and pulleys or directly driven by the motor through the clutch, the motor driver is used to drive the motor, and the control system is used to control the entire working process of the washing machine . [0003] With the improvement of technological innovation and living standards, people have higher and higher requirements for the intelligence, functi...
