Check and Use Fresh Water

- Fill the water reservoir with the descaling solution or vinegar mixture.
- Run a brew cycle without a K-Cup, repeating until the reservoir is empty.
- Follow with 2-3 cycles of fresh water to rinse out any remaining solution or vinegar taste.
Clean the Brew Head and Needle
- Use a paperclip or the cleaning tool included with some maintenance kits to clear any blockages in the needle.
- Open the brew head and gently remove any trapped coffee grounds or debris.
- Run a cleaning cycle with water to flush out residues.
