Many chemicals both in the detergents and possibly in water can cause damages to the machine. There are some other problems like hosepipes or other fittings getting loosened in the course of time. Improper electrical connections can also cause damages to the machine. No one can predict the problems that may occur due to moisture, heat, chemicals and electricity. Overloading of clothes also can cause damage to the machine.
Improper maintenance will cause periodical breakdown of the machines causing avoidable expenses. Some of the consumers are under the impression that warranty conditions attached to the machines will take care of the expenses in case of breakdowns. But they forget the fact that they can invoke the warranty conditions only for inherent manufacturing defects and not for defects caused by improper handling and maintenance of the machines. In many cases manufacturers find that the problems caused to the machines are not due to any deficiency on their parts, but due to sheer negligence of the users. Ultimately consumers will have to pay for the repairs or replacements of the parts in the machines, causing avoidable expenses.
