Possible Causes

Corrupted control board firmware, Internal ADC failure on PCB, Simultaneous sensor faults (bottom NTC and pressure sensor), Power surge damage to electronics

How to Fix / Troubleshooting

Safety first: Unplug the appliance for at least 10 minutes before further checks.

  • Power reset: Disconnect from mains for 10–15 minutes to allow capacitors to discharge. Reconnect and test again; transient errors may clear.
  • Check all sensors: Verify that bottom NTC, lid NTC, and pressure sensor connectors are all firmly seated and wiring is intact.
  • Inspect PCB: Remove bottom and top covers to access the main board. Look for burn marks, swollen capacitors, or corrosion. If found, the board should be replaced.
  • Surge protection: If the error followed a power outage or lightning, consider using a surge protector after repair.

Warning: Component‑level repair of the PCB should only be done by qualified technicians. For most users, replacing the entire control board is the safe option.
