How to Fix / Troubleshooting
Safety first: Unplug the coffee maker before any inspection. Work only if you are comfortable with mains-voltage safety.
Basic checks:
- Verify the wall outlet with another appliance.
- Check that any external power switch on the machine is in the ON position.
- Inspect the power cord for cuts, burns, or kinks.
Internal checks (advanced):
- Remove the bottom or rear cover to access the power entry area.
- Locate the internal fuse on the main PCB or near the power inlet and test it with a multimeter. Replace only with the same rating if blown.
- Check the mechanical power rocker switch for continuity when turned on.
- If fuse and switch are good, the main control board may be defective and require replacement.
