Possible Causes
Scale on heater reducing heat transfer, Faulty thermistor reading high, Incorrect temperature setting, Heater not reaching full power
How to Fix / Troubleshooting
Safety first: Unplug before moving the brewer.
- Descale thoroughly: Scale on the heater can significantly reduce brew temperature. Run at least one full descale cycle.
- Preheat cup: Rinse your mug with hot water before brewing to reduce heat loss.
- Check temperature settings: Some models allow higher temp settings; set to the hottest option.
- Measure temperature: Use a food thermometer to check coffee temperature immediately after brewing (typically 170–190°F / 77–88°C). If far below spec after descaling, the heater or thermistor may be faulty and require service.
