Possible Causes
Brew water temperature too high, Coffee sitting too long on warming plate, Incorrect grind size (too fine), Excessively long brew time due to partial blockage
How to Fix / Troubleshooting
Safety first: Unplug the unit before cleaning or descaling.
- Turn off warming plate sooner: Use the shortest keep-warm setting or turn off the coffee maker once brewing is complete.
- Adjust grind and dose: Use a slightly coarser grind and avoid overfilling the basket.
- Descale to normalize flow: Run a descaling cycle to remove scale that can slow flow and increase contact time.
- Check warming plate temperature: If the plate seems excessively hot (scorching the coffee), the thermostat may be faulty and should be tested and replaced if necessary.
Persistent burnt taste even with fresh coffee and proper technique may indicate a thermostat or control issue regulating brew temperature.
