Possible Causes

How to Fix / Troubleshooting
Safety: Ensure the cooker is on a stable, dry surface.
- 1. Confirm mode and time: Select a cooking program, adjust time if needed, and press Start (or equivalent) firmly once.
- 2. Check lid and vent: For pressure modes, ensure the lid is locked and the steam release is set to Sealing. Some models will not start if the lid is not correctly positioned.
- 3. Power cycle: Unplug for 5–10 minutes, then retry.
- 4. Try non-pressure mode: Test Saute or Slow Cook. If these also fail to start, the issue is likely with the control board or relay.
- 5. Professional diagnosis: A technician can test the start button contacts, lid interlock circuit, and main PCB relays, replacing the faulty component.
