You can also buy washing machine parts from a bricks and mortar store - if you can find one nearby. You will often have to end up ordering it at the store and then going back to collect it when it finally arrives, as many stores do not keep any but the most common parts now. They do this to reduce their own costs as it is no point them carrying a lot of parts that may well not be needed. They could sit on the shelf for years until that model appliance went out of date and then they would never get sold.
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.
