As with any appliance, the coffee machine has a lifespan that can be determined by the type and usage. The average lifespan of a coffee machine is usually 5-10 years, but this may vary depending on the brand and type of machine.

When determining the lifespan of the coffee machine, consider the type of machine, brewing method, grind size, and personal preferences. If you find that the machine is not working as expected or has a worn-out appearance, it may be time to replace it.

In general, the lifespan of a coffee machine should be considered as part of the overall appliance maintenance plan, and regular cleaning and maintenance can help extend its life. However, this is also true of any appliance, so the best approach is to follow manufacturer's instructions for cleaning and maintenance, and consult a professional appliance repair shop if necessary.
