Possible Causes
Blown thermal fuse, Open heating element, Loose heater wiring, Burned connector at heater terminals
How to Fix / Troubleshooting
Safety first: Unplug the coffee maker and allow it to cool completely. Heating components can retain heat and electrical charge.
- 1. Access heater assembly: Remove the base or rear panel to expose the aluminum heater tube or boiler block and its wiring.
- 2. Inspect wiring and connectors: Look for burned or loose spade connectors at the heater. Tighten or replace damaged connectors.
- 3. Test thermal fuse: Locate the thermal fuse attached to the heater. Use a multimeter to check continuity. If open, replace it with an identical rating fuse.
- 4. Test heating element: Measure resistance across the heater terminals. An open circuit indicates a failed element that must be replaced.
- 5. Reassemble and test: After replacing any failed components, reassemble the unit, plug it in, and test for normal heating.
