How to Fix / Troubleshooting
Safety first: Ensure the machine is on a stable power outlet with proper grounding.
- Power cycle reset: Turn the machine off with the main switch (if present), unplug it for 10 minutes, then reconnect and power on.
- Complete pending cycle: If E08 appeared during descaling or cleaning, re-enter the same program from the menu and allow it to run to completion without interruption.
- Factory reset: Consult the Grundig user manual for the procedure to reset the machine to factory settings. Perform the reset and then reconfigure language and preferences.
- Stable power supply: Avoid using long extension cords or multi-socket adapters that may cause voltage drops.
- Service if persistent: If E08 remains after reset and completing cycles, the main control PCB may be faulty and require replacement.
