Possible Causes
Heater not reaching proper temperature, Thermostat opening too early, Excessively coarse grind, Incorrect brew strength setting
How to Fix / Troubleshooting
Safety first: Allow the unit to cool before internal inspection. Unplug during any disassembly.
- 1. Adjust coffee and grind
- Use a medium grind suitable for drip coffee makers.
- Increase the amount of coffee grounds slightly if needed.
- 2. Check brew strength setting
- On models with a strength selector, choose a stronger setting or "bold" mode.
- 3. Descale the unit
- Scale buildup can reduce heating efficiency; run a full descale cycle.
- 4. Test brew temperature (advanced)
- Run a brew cycle with water only and measure the temperature of the water entering the carafe; it should typically be around 90–96°C (194–205°F).
- If significantly lower, the heater or thermostat may be faulty.
- 5. Replace heater or thermostat
- If the unit cannot reach proper temperature after descaling, replace the heating element or thermostat assembly.
