1. Temperature controller failure: if the temperature controller fails, the rice cooker will not be able to automatically control the heating temperature, the E19 failure will occur.
2. Insufficient power to keep warm: When the rice cooker does not have enough power to keep warm and keep warm for a long time, the E19 fault will occur.
3. Plugging and unplugging power during keep warm mode: if you plug and unplug the power during keep warm mode, it will cause an error in the rice cooker system and E19 fault will occur.
For the E19 fault, you can do the following:
1. Try to restart: First, you can try to restart the rice cooker to see if it can solve the problem. This is done by disconnecting the power and reconnecting it later, then pressing the switch to start.
2. Confirm that the temperature control is working properly: If the E19 fault still occurs after restarting, it is recommended that you take the rice cooker apart to see if the temperature controller is working properly. If the temperature controller is faulty, it will need to be replaced.
3. Confirm the holding time: If the rice cooker keeps warm for too long, you can choose to reduce the holding time or remove the food in time.
4. Avoid plugging and unplugging the power supply: Please avoid unplugging the power supply when the cooker is in keep-warm mode.
If none of the above measures can solve the E19 failure problem, we recommend you to contact the after-sales service department for professional help or replace the rice cooker.
