F8 error appears when attempting to start any program after a power outage.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Corrupted EEPROM settings, Incomplete write during power loss, Firmware bug, PCB memory chip failure

Safety first: Unplug before performing resets.

Factory reset: Use the ProCook factory reset procedure (often holding specific keys while plugging in) to clear stored settings.
Stable power: Plug the cooker into a known-good outlet without extension cords or power strips to avoid further brownouts.
Test basic functions: If basic cooking works after reset, monitor for recurrence. If F8 returns frequently, the PCB memory is likely failing.
Replace PCB: Persistent F8 generally requires main control PCB replacement.
