A repair plan for the washing machinery malfunction has been determined.

When determining the repair plan for a washing machine, the faulty parts should be disassembled or replaced. The basic principles of washing machine disassembly are as follows.

Ensure safety for both people and machines. Before disassembling the washing machine, please unplug the power cord to prevent accidental contact with live parts. Also, protect the washing machine by using proper tools to avoid damage.

Which part is malfunctioning, which part is being removed. The entire unit or other unrelated parts must not be disassembled when the fault location is unrelated to other connected components, or when other parts of the unit do not interfere with the fault repair work.

During the disassembly process, dismantled parts should be arranged in order or numbered for easy use and to prevent installation errors, as well as to avoid part loss. Dismantled parts should be cleaned thoroughly. For connections that are difficult to dismantle due to rust, lubricant should be applied first and not forced. Otherwise, it is easy to damage the parts.

During disassembly, pay attention to the threading direction of the threaded connections. Generally, this is a right-hand thread. If you continue to rotate in the opposite direction or apply excessive force after tightening, the threaded connection will break.

After removing the faulty component, re-inspect and analyze whether it can be repaired and reused. Replace with new parts if the repaired component has a shortened lifespan or fails to meet performance requirements.

If an electric motor needs to be replaced due to burning out, the cause of the burnout should also be investigated. When the motor windings are damaged due to leakage, the leakage phenomenon should be addressed simultaneously. If the motor burns out due to a short circuit or stalling, identify the cause of the short circuit or stalling, rectify the fault, and ensure it does not recur.

Disassembly of washing machine assemblies is quite difficult. Therefore, during the reassembly after repair, it is essential to be meticulous and pay close attention to the relationships and positions of each component during disassembly.

After assembly, lubricate the parts with relative movement using grease to alter the friction state and extend service life. Once assembled, connect the power source and conduct an unloaded operation test to observe if the running state is normal and if the faults at the inspection locations have been eliminated. Only after confirming there are no issues should the product be used.
