Why is my coffee maker not pushing water through?
When your coffee maker stops pumping water, the appliance probably needs to be descaled. Hard water build-up may be affecting your coffee machine’s ability to pump water through it to make coffee. Simply run a descaling cycle to clear the build-up. Clogging is another common culprit behind noisy coffee machines. Residues and mineral deposits can accumulate in the water or coffee grounds. Regular descaling will alleviate this problem. If you live in an area with hard water, using bottled water can also help.
Why is my coffee maker 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^]. Many times, the most likely reason for weak tasting coffee is an incorrect coffee to water ratio; namely too much water for too little coffee. Other possible factors can include incorrect grind size, stale coffee beans, brewing too quickly or incorrect water temperature.
