Swan coffee maker overheats coffee on the warming plate, causing burnt taste.
Safety Warning
This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.
If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.
Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the coffee maker and allow the warming plate to cool completely.
User actions:
- Use keep-warm timer: If your Swan model has an adjustable keep-warm time, reduce it to the minimum to prevent prolonged heating.
- Clean the plate: Remove burnt coffee residue from the warming plate, as it can create hot spots.
Technical checks:
- Access the underside of the warming plate to locate the plate thermostat or sensor.
- Test the thermostat for proper opening temperature if you have the specification; a thermostat that never opens will overheat the plate.
- Inspect the control PCB relay that drives the plate; if welded closed, the plate will stay on continuously and the relay must be replaced.
Persistent overheating indicates a faulty thermostat or control board that should be replaced with the correct Swan part.
