Step 2: Check the Water Reservoir
- Remove the water reservoir from the unit.
- Empty and rinse it thoroughly with clean water.
- Refill with fresh, cold water up to the MAX fill line.
- Re-seat the reservoir securely onto the machine.
Step 3: Descale the Coffee Maker
Mineral buildup can cause partial brewing. Use a descaling solution or a mixture of equal parts water and white vinegar.
- Fill the water reservoir with the descaling mixture.
- Place a mug on the drip tray.
- Run a brew cycle without a K-Cup, letting the solution pass through.
- Repeat with clean water to rinse out any residual descaling solution.
Step 4: Clean the Needle and Brew Area
Clogged needles can block water flow. Use a paperclip or needle cleaning tool to clear any debris or coffee grounds from the needle.
- Open the top or access panel as per your model’s instructions.
- Gently insert the tool into the needle to dislodge any buildup.
- Rinse the area with water and run a brew cycle to test.
Step 5: Test the Brew and Adjust
After cleaning and descaling, run a test brew with a K-Cup. Ensure the machine is set to your desired brew size (6-12oz). If the cup still isn’t full, repeat descaling or check for leaks or blockages.
