Restart the device: you can try to shut down the device after the heating rod E3 alarm, wait for a few minutes and then restart the device, you can recover.
Bot heating rod is a device used to heat liquid or gas, usually consists of a heating rod, temperature sensor, controller, etc. Bot heating rod is mainly used in the laboratory, medical, industrial and other fields, and can be used to heat reagents, solutions, gases and so on, Bot heating rod is usually electrically heated, through the heat generated by the heating rod to heat the liquid or gas to the required temperature. The temperature sensor can monitor the temperature of the surface of the heating rod, the controller can control the heating power of the heating rod according to the feedback signal of the temperature sensor, so as to realize the precise heating control of the liquid or gas.
