Possible Causes
Scale buildup in the thermoblock, faulty NTC sensor reading high, control board temperature calibration drift, or user not preheating the cup.
How to Fix / Troubleshooting
User-level steps:
- Preheat cups with hot water before brewing.
- Run a blank shot (without capsule) to warm the brew path.
- Perform a full descale to improve heat transfer.
Technical steps:
- Check the NTC sensor resistance and replace if it is out of specification.
- If temperature remains low despite a good sensor and clean thermoblock, the control board may be under-driving the heater and should be replaced.
