How to Fix / Troubleshooting
Safety first: Unplug the appliance before inspecting any electrical connections. Only qualified persons should work on mains circuits.
- Check outlet and cord: Verify the wall outlet has correct voltage and is not loose. Inspect the power cord for damage or kinks.
- Power reset: Leave the machine unplugged for at least 10 minutes, then reconnect and test.
- Avoid shared high-load circuits: Do not run the coffee maker on the same circuit as heavy appliances that may cause voltage drops.
- If E14 remains or the unit will not power correctly: The internal power supply or main PCB likely needs replacement. This involves high-voltage work; contact Bosch service.
