Possible Causes
Blocked water flow causing boiler overheat, Excessive scale buildup in boiler, Failed thermostat not opening in time, Thermal fuse blown due to overheating
How to Fix / Troubleshooting
Safety: Unplug the coffee maker and let it cool for at least 30 minutes.
- Check for blockage: Inspect the outlet arm and brew basket for clogs. Ensure the drip-stop is not stuck closed.
- Descale: Perform a full descaling cycle to remove scale that can cause localized overheating in the boiler.
- Internal inspection (advanced):
- Remove the base and locate the thermal fuse and thermostats on the boiler.
- If the unit will not power back on after cooling, test the thermal fuse for continuity. An open fuse indicates it has blown and must be replaced.
- Investigate the root cause (scale, failed thermostat, blocked tube) before installing a new fuse.
- Prevent recurrence: Descale regularly according to water hardness and manufacturer recommendations.
