How to Fix / Troubleshooting
Safety: Unplug the brewer before inspection. If the unit is very hot, allow it to cool.
Steps:
- 1. Check cord and plug: Ensure the plug fits tightly in the outlet and that the cord is not being pulled or flexed excessively.
- 2. Inspect internal connections: Tighten any loose connections at the power entry, switch, and control board.
- 3. Ventilation: Make sure the brewer has adequate space around it for cooling and that vents are not blocked.
- 4. Control board and thermal devices: Inspect the control board for overheating signs and test any thermal cutouts. Replace components that are tripping prematurely or show damage.
