Possible Causes
Brew water too hot due to faulty thermostat, Coffee left on hot plate too long, Too fine grind or too much coffee, Dirty coffee oils in brew path
How to Fix / Troubleshooting
Safety first: Unplug before cleaning. Hot plate can remain hot after brewing.
Steps:
- Adjust coffee recipe: Use a slightly coarser grind and reduce the amount of coffee slightly to avoid over-extraction.
- Limit warming time: Do not leave coffee on the warming plate for extended periods. Use a thermal carafe model or transfer coffee to a thermal container.
- Clean thoroughly: Run a cleaning cycle with a mixture of water and a coffee machine cleaner to remove rancid oils from the filter basket, carafe, and shower screen.
- Descale: Remove scale that can cause uneven heating.
- Thermostat check: If coffee is excessively hot or has a burnt smell immediately after brewing, the thermostat or temperature sensor may be faulty and require replacement.
