Nowadays, sewing machines have benefited enormously from the rapid improvements in technology and manufacturing. They are well built and designed to last for years without giving you any trouble. Generally, even if something does go wrong, there are only a few sewing machine parts which might require replacing. Think about how many antique sewing machines are still being used today. I personally still have my mother's old sewing machine, which is probably at least 30 years old now and still going strong! Even so, the older a machine gets, the harder it can become to get replacement parts. Sometimes that's just because the manufacturer doesn't make them any more, but other times it could be that the manufacturer has gone of business. If possible, you should always try and source parts from the original manufacturer.
When it's just not possible to buy parts from the original manufacturer, then you may like to turn to one of the companies who now specialize in sewing machine parts. Many of these parts are “universal", which means they can be used in a wide variety of sewing machine brands and machines. Most parts in your modern sewing machine only need to be maintained occasionally. These include the needles, light bulbs and belts. You can buy and replace these smaller parts with relative ease, as they can be found at most sewing-oriented retailers.
There are other parts, however, that are not quite so easy to find ore replace. These include more machine specific items like bobbins, needle plates and feet attachments. Generally you can only buy these from a sewing machine shop or dealer. It's important that you supply them with the correct brand and model number of your sewing machine, to ensure they can work out the right part number and order the correct replacement part. You can also buy additional parts for your sewing machine, including special attachments for quilting or ruffles. Always check that these after-market parts are suitable for your particular sewing machine. Generally, after-market attachments will only be suitable for the manufacturer's specific brand.
If your sewing machine is a popular brand, such as Singer, then there are suppliers and repair shops that are dedicated solely to selling and servicing that brand's sewing machines. They will also be able to give you general tips about care and maintenance of your sewing machine.
