There’s a chalky white coating building up inside my coffee maker’s water tank. What is it?

If limescale build-up has been neglected for too long, it can cause irreversible damage to your coffee maker. Signs that limescale has taken its toll include persistent performance issues, such as irregular brewing times, inconsistent temperatures, or leaks.

If multiple descaling attempts fail to restore your machine’s functionality, it might be time to consider replacing it. Frequent breakdowns or repairs can be more costly than investing in a new coffee maker, especially if the internal components are severely affected.

Investing in a water filter can significantly reduce the hardness of the water you use in your coffee maker. Many home filtration systems are available, ranging from faucet attachments to whole-house softeners. These systems can lower the mineral content in your water, reducing limescale build-up.

If installing a filtration system isn’t feasible, using pre-filtered or distilled water for your coffee maker can also help. While this might be more expensive than tap water, it can prevent limescale and keep your coffee maker running smoothly for longer. Regular maintenance, combined with these preventive measures, can effectively manage and even eliminate limescale issues.
