E3 error code means that CNC spindle cooler CW-5200 has ultralow water temperature. This happens very often in winter in cold areas, for the ambient temperature in those areas is likely to be below 0 degree Celsius and water can easily freeze. To remove the E3 error, one can put a heating bar or add anti-freezer into the spindle chiller unit. For detailed instructions, please e-mail to techsupport@teyu.com.cn
