Knowing how your washing machine works will be helpful in times of distress. When you how each part functions, you know what causes any malfunction too. With that, you can point out which spare parts to purchase. Buying washing machine spare parts saves you money. Repair costs are less expensive than replacing the unit altogether. These parts are available in specialty shops online and in local stores.
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 They could sit on the shelf for years until that model appliance went out of date and then they would never get sold.
