Coffee maker starts but stops brewing after a few seconds; only a small amount of water passes through.

Safety: Unplug and allow the unit to cool before servicing.

• 1. Descale thoroughly:
  • Run multiple cycles with a 1:1 vinegar and water solution.
  • Pause between cycles to allow the solution to soak in the heater and tubing.
• 2. Inspect water lines:
  • Remove the top cover and trace the silicone tubing from the reservoir to the heater and brew head.
  • Look for kinks, pinches, or visible mineral deposits. Replace any hardened or blocked tubing.
• 3. Check the pump:
  • Listen for the pump during operation; if it hums but flow is weak, the pump may be failing.
  • Test pump resistance and replace if out of specification or mechanically noisy.
• 4. Inspect thermal cutoff:
  • If the unit stops abruptly and resumes after cooling, the thermal cutoff may be opening due to overheating.
  • Clean scale from the heater and ensure proper ventilation; replace the thermal cutoff if it has weakened.
