How to Fix / Troubleshooting

Safety first: Unplug the machine before removing the water tank or covers.

Clearing airlock:

Prime the system: Fill the water tank completely and firmly reseat it. Run a hot water cycle (if available) without coffee. Repeat several times.
Lift and tilt: While the pump is running (for experienced users only, with covers on), gently tilt the machine forward and sideways to help air move through the hoses.
Clean inlet filter: Remove the tank and clean the mesh filter at the tank connection.
Check non-return valve: Inside, locate the small check valve near the pump inlet. If stuck, replace it with a compatible valve.

Note: If the pump continues to buzz without moving water after priming and cleaning, it may need replacement.

Water is not being drawn from the tank; pump makes a loud buzzing noise but no water reaches the brew head.
