Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the coffee maker before opening the housing.
Basic reset:
- Unplug the unit for at least 10 minutes to discharge internal capacitors.
- Plug back in and test. If E5 appears immediately, proceed to inspection.
Inspect control panel:
- Check for signs of moisture or coffee spills around the display and buttons. Wipe the exterior dry.
- If the panel was recently exposed to steam or a spill, leave the unit unplugged in a dry, warm area for 24 hours to allow moisture to evaporate.
Internal cable check (advanced):
- Remove the top or front cover to access the control board and keypad ribbon cable.
- Ensure the ribbon cable is fully seated in its connector and not damaged or corroded.
- If corrosion is present, clean gently with isopropyl alcohol and let dry before reassembly.
If E5 persists after drying and reseating cables, the control board or keypad membrane is likely defective and should be replaced as an assembly.
