U18 code appears and the cooker does not start or stops unexpectedly.

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

Loose ribbon cable between keypad and PCB, Oxidized connector contacts, Damaged control panel membrane, Faulty main PCB

Safety first: Unplug the cooker before opening the housing.

Panel connection checks (advanced):

Remove the outer shell or front panel to access the keypad ribbon cable and main PCB.
Carefully disconnect and reconnect the ribbon cable to clean the contacts.
Inspect the cable for kinks, cracks, or broken traces.
Check the PCB for signs of moisture or corrosion around the connector.

If reseating the cable does not resolve U18, either the keypad assembly or the main board may need replacement.
