ProCook Mode Selector / Function Logic Error

F4 error appears when switching between modes or adjusting temperature.

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

Faulty mode selection buttons, Dirty keypad contacts, Firmware glitch, Control PCB logic failure

Safety first: Unplug before cleaning the control panel.

Clean keypad surface: Wipe the panel with a slightly damp cloth and mild detergent. Do not allow liquid to seep into the panel.
Power reset: Unplug for 10 minutes, then plug back in and try selecting modes again.
Check for stuck keys: Ensure no button is permanently pressed down. If a key cap is misaligned, gently realign it.
Panel replacement: If F4 persists, the control panel or main PCB may need replacement.
