E07 appears and the cooker will not start pressure or high-heat modes.

Safety first: Unplug the unit and ensure it is completely depressurized and cool before any inspection. Never open a pressurized cooker.

• Clean steam and pressure paths: Remove the steam cap and inner pressure cap (if equipped). Clean all holes and channels with a soft brush and warm soapy water. Rinse and dry thoroughly.
• Inspect for clogs: Look for hardened starch or food blocking the steam vent or pressure port. Do not use metal picks that could enlarge or damage the openings.
• Reassemble correctly: Ensure the pressure cap, steam cap, and gaskets are reinstalled in the correct orientation as shown in the manual.
• Reset and test: After reassembly and drying, plug in and try a short pressure cycle with water only. If E07 persists, the internal pressure sensor or its tubing may be faulty.

When to call a technician: Internal pressure sensor or hose replacement requires opening the housing and must be done by qualified service personnel for safety.
