It is not difficult to buy washing machine parts; however, it may be a little more difficult to pull that machine down and find out exactly what part is broken. If you are a true handyman, then this may not be anything to worry about, but for those who are not used to anything mechanical then it could pose a problem. The best thing to do is to get that repairman in to do the job and tell you what is needed.
It is not a very hard job for the consumer to maintain the machine in good condition. At the outset the users should follow the instructions given in the manual supplied along with the machine. Manufacturers prescribe certain methods to maintain the machine in good condition. Physical inspection of the interior and exterior of the machine before and after every wash is necessary. Never overload the machine with more clothes than what is prescribed. Electrical connections should be perfect not only to protect the machine but also the person who operates it.
