Bodum pour-over coffee maker (e.g., Bodum Bistro, Bodum Pour Over) does not heat water at all; indicator light may turn on but no brewing occurs.

Safety first: Unplug the coffee maker and let it cool. Internal heater wiring carries mains voltage.

Steps to try:

• Check outlet and cord: Test the outlet with another appliance. Inspect the Bodum power cord for cuts or burns. Do not use if damaged.
• Verify switch operation: Toggle the on/off switch several times. If the indicator light flickers or never comes on, the switch may be faulty.
• Internal inspection (advanced): Remove the base screws and lift off the bottom cover. Locate the aluminum heating tube and attached thermal fuse. Check for burnt or disconnected wires.
• Continuity test (advanced): With a multimeter, test continuity across the heater and thermal fuse. An open reading indicates a failed component that must be replaced.

Note: If you are not comfortable testing live circuits, limit yourself to visual checks and contact a technician for heater or fuse replacement.
