The Water Filter in your Breville Infuser BES840 removes impurities from the water used for brewing, ensuring the best possible taste and preventing mineral buildup in your machine. Over time, the filter's effectiveness diminishes, potentially leading to reduced coffee quality, clogs, or damage to internal components. Replacing the filter every 6 months helps maintain your device's performance and longevity.
