Possible Causes
Weak heating element, Thermostat opening too early, Heavy scale on heater reducing heat transfer, Faulty temperature sensor
How to Fix / Troubleshooting
Safety first: Unplug before internal checks.
- Preheat carafe: Rinse the carafe with hot tap water before brewing to reduce heat loss.
- Descale: Run a full descaling cycle to restore proper heat transfer in the heater tube.
- Check warming plate: Confirm that the warming plate heats up during and after brewing. If it remains cool, the heater or thermostat may be faulty.
- Advanced testing: With a thermometer, measure coffee temperature immediately after brewing; it should typically be around 175–185°F (79–85°C). Significantly lower temperatures indicate a heating system problem requiring heater or thermostat replacement.
