Description: blinking indicates a faulty pressure sensor with error codes C6, C6L, C6H, E4. The pressure sensor is faulty, in most cases this is due to build-up on the sensor contacts, cleaning the contacts will solve the problem. If the problem is still not resolved, a new pressure sensor is required.
To test the new replacement pressure sensor: pour 3 cups of water into the pressure cooker and set to high pressure for 5 minutes. If the emergency vent begins to leak or vent during the heating cycle, the pressure in the cooker is too high.
