Possible Causes

Scale buildup on heating element, Faulty temperature sensor, Incorrect brew setting (e.g., over-iced mode), Cold carafe pre-chilling coffee

How to Fix / Troubleshooting

Safety first: Allow the unit to cool before descaling.

Descale to restore heat transfer:

  • Run a full descale cycle with vinegar or Ninja descaler.
  • Rinse thoroughly with 2–3 full reservoirs of water.

Usage tips:

  • Pre-warm the carafe with hot tap water before brewing.
  • Ensure you are not using an iced or specialty setting that intentionally brews cooler.

If coffee remains consistently lukewarm, the temperature sensor or heater control may be faulty and require service.
