User Suggested Solutions

Run a cleaning cycle using a commercial coffee machine cleaner or a mixture of equal parts water and vinegar. Fill the water reservoir with the solution, run a brew cycle without coffee grounds, then run two cycles with clean water to rinse.
Use citric acid to descale the machine. Dissolve 1-2 tablespoons of citric acid in water, fill the reservoir, and run a brew cycle. Rinse thoroughly afterward with clean water.
Disassemble removable parts (like the brew basket and water reservoir) and wash them with warm, soapy water. Ensure all parts are thoroughly dried before reassembling.
