Step 2: Descale Your Keurig
Mineral buildup can restrict water flow, causing incomplete brewing. Use a descaling solution like the Keurig Descaling Kit or other approved products.
- Fill the water reservoir with the descaling solution diluted according to instructions.
- Run a cleansing brew cycle without a K-Cup, following your machine’s manual.
- Repeat with fresh water to rinse out any residue.
Step 3: Clean the Needle and Exit Point
Coffee grounds or mineral deposits can clog the needle that punctures the K-Cup and the exit needle.
- Turn off and unplug the machine.
- Use a paper clip or the cleaning tool provided to gently clear any blockages in the needle holes.
- Run a water-only brew cycle to flush out remaining debris.
Step 4: Check and Adjust Brew Size
Ensure you select the correct brew size on your K-Mini. Sometimes, selecting a smaller size can cause the machine to underfill.
- Double-check the brew size setting before starting.
- Use the full range (6-12oz) for optimal fill.
Additional Tips and Warnings
- Always use filtered water if possible to reduce mineral deposits.
- Avoid overfilling the water reservoir to prevent leaks or improper brewing.
- Regular descaling (every 3-6 months) keeps your machine functioning well.
- Never use harsh chemicals or abrasive tools to clean your Keurig.
