3.4.5. Notify the maintenance company to come home for repair;
6. Remove the nozzle for cleaning (please disassemble carefully).
8. Cannot run after turning on the power
Cause of failure: When the water level in the heating tank is too low, the power supply for operation will be cut off.
Treatment method: increase the water level of the heating tank to normal conditions.
Nine, when the temperature controller displays HHH, LLL
Causes of failure: temperature controller failure, temperature sensor failure.
Solution: notify the maintenance company to repair
