U12 or similar code appears during pressure cooking; cooker may switch to keep warm.

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

Insufficient liquid, Steam leak from valve or gasket, Overfilled pot causing foaming, Faulty pressure sensor

Safety first: Allow pressure to release before opening.

Check liquid level: Ensure minimum liquid requirement is met (refer to manual, typically at least 200–300 ml).
Inspect for leaks: During a test with water, look for continuous steam escaping.
Clean and replace seals: Clean the steam release valve and replace the sealing ring if worn.
Re-test: Run a short pressure cycle with water only. If U12 persists, the pressure sensor or control board may be faulty.
