Wash all the removable parts thoroughly in the dishwasher or by hand with soapy water. Coffee can leave behind an oily residue that builds up over time and gives a bad taste to your beverage.
When the clean alert light comes on or your coffee maker begins to take longer than usual to brew, it's time to descale, which means removing mineral deposits that build up inside the machine. Start by removing the charcoal water filter. Run a mixture of equal parts white vinegar and water through the machine. Follow up with a cycle of plain water. Then, replace the charcoal filter.
On single-serve coffee makers, the needle may get clogged, resulting in grounds in your coffee or a smaller cup of coffee than the size you selected. To fix this, begin by unplugging the machine. To unclog the exit needle, remove and disassemble the pod holder and then use a paper clip to clear away any debris. You lift the head and use the paper clip to clean the entrance needle. Refer to your manual for complete instructions with diagrams.
