This is a drawback of many electric water heaters, which may cause the risk of electric shock during bathing. Macro electric water heater has a patented technology of "no electric washing". After turning on the power-free washing function, the whole machine will be without electricity within 0.5 seconds of water discharge. It is not only a simple power outage when the water is discharged, disconnecting the power supply of the machine, but also preventing electric shock hazards caused by leakage of other electrical appliances. This ensures that during the bathing process safer. When you no longer use the electric water heater, it will turn on the power supply by itself. I have to say that this design is quite clever, saving power and providing peace of mind.
