How to Fix / Troubleshooting
Safety first: Unplug the coffee maker immediately and do not use it until repaired. This is a fire risk.
Internal diagnosis (advanced):
- Remove the bottom or rear cover to access the main PCB.
- Identify the warming plate relay or triac and inspect for signs of overheating or burning.
- Test the relay contacts for continuity when the machine is off; they should be open.
Replace the main control board or the specific relay/triac if you have the skills and tools. Due to safety implications, professional repair is strongly recommended.
