Possible Causes

Airlock in inlet line from reservoir, Weak or failing vibration pump, Clogged inlet filter screen, Kinked silicone hose between reservoir and pump

How to Fix / Troubleshooting

Safety first: Unplug the unit and let it cool before handling.

  • Bleed air from system:
    • Fill reservoir to MAX with water.
    • Remove and reinsert reservoir several times to help purge trapped air.
    • Plug in and start a brew with no coffee; listen for the pump. If it hums but no water flows, stop after 30 seconds to avoid overheating.
  • Clean inlet area:
    • Remove reservoir and inspect the base inlet for debris.
    • Use a damp cotton swab to clean the inlet port.
  • Check for hose kinks (advanced):
    • With the unit unplugged, remove the bottom cover (usually Phillips screws) if accessible.
    • Inspect the silicone hose from reservoir inlet to pump for kinks or pinches; straighten as needed.

If the pump is noisy but still not moving water after these steps, the vibration pump may be failing and should be replaced by a technician.
