Why is my coffee machine turning on but not brewing?
If your coffee machine is powering on but not brewing, the culprit might be a blocked water line or heating element. Mineral buildup from hard water can clog these components, preventing the water from reaching the right temperature or flowing into the brew basket[^2^]. Whether it’s a drip coffee machine or a single-serve coffee machine, slow or no water flow is the most common problem with all home coffee machines, and there are a few causes behind this problem. Firstly, the water tank might be out of place.
