Possible Causes

Safety first: Unplug before accessing internal temperature controls.

Usage adjustments:

Use a slightly coarser grind and reduce the amount of coffee if over-strong.
Do not leave coffee on the warming plate for extended periods; transfer to a thermal carafe if needed.

Temperature control (advanced):

Check the thermostat or temperature sensor on the heater for proper mounting.
If the warming plate runs excessively hot even on low settings, the thermostat or control board may be faulty and require replacement.
