Step 2: Clean the Parts
- Detach the drip tray and water reservoir; wash with warm, soapy water.
- Clean the needle area carefully with a Keurig cleaning tool or a paperclip to remove any clogs.
- Wipe the exterior with a damp cloth.
Step 3: Use Filtered or Fresh Water
Always use filtered or bottled water for brewing. Stale or hard water can cause mineral buildup and affect flavor. Refill the water reservoir with fresh water before each use.
Step 4: Check and Replace K-Cups or Grounds
If using reusable filters, replace grounds regularly and clean the filter. For K-Cups, discard old or stale pods, and store new ones properly to maintain freshness.
Tips & Warnings
- Never run the descaling process without water to avoid damaging the machine.
- Perform descaling every 3-6 months, or more often if you have hard water.
- Avoid using harsh chemicals or abrasive cleaners.
- Always unplug the machine before cleaning or maintenance.
