Possible Causes

Empty or improperly seated reservoir, Severe scale blockage in heater tube, Air lock in pump, Failed pump motor (on pump-driven models)

How to Fix / Troubleshooting

Safety first: Unplug and cool the unit before troubleshooting.

  • Verify water supply: Ensure the reservoir is filled and fully seated. Check for cracks or leaks in the reservoir that might prevent suction.
  • Prime the system: Fill the reservoir completely, then start a brew cycle. If possible, gently tap the side of the machine to help dislodge air bubbles.
  • Descale aggressively: Run multiple descaling cycles back-to-back using a vinegar solution to dissolve internal blockages.
  • Listen for heater and pump: If you hear the heater boiling but no water moves, the outlet may be blocked. If you hear no pump noise on a pump-driven model, the pump may have failed.

If no water flows after repeated descaling and confirming reservoir placement, internal tubing, heater passages, or the pump likely need professional service or replacement.
