Washing machine repair involves diagnosing and fixing issues that prevent the appliance from functioning properly. Common problems include leaks, unusual noises, and failure to start. Technicians often check components like the drum, motor, and water pump to identify the source of the malfunction. Repairs can range from simple fixes, such as replacing a worn-out belt, to more complex tasks like addressing electrical issues. Regular maintenance, such as cleaning filters and checking hoses, can help prevent breakdowns and extend the life of the washing machine.
