Possible Causes
Aging NTC sensor out of range, Faulty ADC circuit on main PCB, Poor contact between inner pot and heater plate causing unstable readings
How to Fix / Troubleshooting
Safety first: Unplug the cooker and let it cool before inspection.
- Check pot contact: Ensure the inner pot is the original Black+Decker pot, not an aftermarket one. It should sit flat and make full contact with the heater plate.
- Clean contact surfaces: Wipe the bottom of the inner pot and the heater plate to remove oil film or residue that can affect temperature sensing.
- Reset and test: After cleaning, plug in the unit and run a short, low-temperature program (e.g., Keep Warm) to see if the error reappears.
- Sensor replacement: If E9 recurs frequently, the internal sensor or main board calibration is likely faulty. Replacement of the sensor/heater plate assembly or main PCB is required.
