ProCook Keep-Warm Circuit / Relay Fault

F5 error appears when the cooker attempts to switch to keep-warm after cooking.

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

Stuck relay on PCB, Faulty low-power heating circuit, Damaged PCB trace to heater, Overheated relay contacts

Safety first: Unplug the cooker before opening the housing.

Listen for relay click: When switching to keep-warm (if you can briefly clear the error), you should hear a soft click from inside. No click may indicate a failed relay.
Visual PCB check (advanced): Inspect the board for burnt areas around the heater relay. Replace the PCB if damage is visible.
Do not bypass safety: Never attempt to bypass relays or hard-wire the heater; this is dangerous.
