      If your Nespresso Coffee Maker isn't working, verify that the mains cable and the On/Off switch are functional. Check if the pump is working by pressing the coffee button and ensure the coffee buttons themselves are functional. Also, inspect the pump's fine wire fuse (128°C) and the thermoblock’s fine wire fuse (167°C) to see if they are defective.
