Display shows E2 and the coffee maker will not heat or brew.

Safety first: Unplug the coffee maker and allow it to cool completely before any inspection.

• Power reset: Unplug the unit for 5–10 minutes to discharge the control board, then plug it back in and check if E2 clears.
• Check for overheating signs: Inspect the warming plate and underside of the unit for burn marks or melted plastic that may indicate an overheat event. If present, discontinue use.
• Clean ventilation: Ensure the bottom and rear vents are not blocked by dust or cabinets. Overheating can trigger sensor faults.
• Test with water: Fill the reservoir with fresh water, reseat it, and attempt a brew. If E2 reappears immediately, the thermistor or its wiring is likely defective and the heater/thermistor assembly or main PCB will need replacement by a technician.

Warning: Accessing the thermistor requires opening the base and exposing mains wiring. If you are not experienced with appliance repair, contact a professional.
