Use a paperclip or a Keurig needle cleaning tool to carefully clear any blockages in the needle that punctures the K-Cup or reusable filter.
Wipe the brew head with a damp cloth to remove any residue.
Step 3: Descale the Machine

Run a descaling cycle, then rinse the machine with clean water to remove mineral deposits that can hinder water flow.

If your model uses a water filter, ensure it is installed correctly and replace it if it’s old or clogged.
Remove and clean or replace the filter according to your model’s instructions.
