Possible Causes

How to Fix / Troubleshooting
Safety first: Unplug the coffee maker before any inspection.
- Power cycle: Unplug the unit for at least 10 minutes. Press and hold the power or start button for 10 seconds while unplugged to help discharge capacitors. Plug back in and check if the error clears.
- Check outlet: Plug the coffee maker directly into a known-good wall outlet (no power strip or extension cord). Avoid outlets shared with high-draw appliances.
- Inspect for moisture: Look around the control panel for signs of condensation or spills. If moisture is present, leave the unit unplugged in a dry, warm area for 24 hours to allow it to dry completely.
- If E8 persists: The main control PCB is likely faulty and will need replacement. This involves opening the housing and transferring wiring harnesses to a new board.
