Why water heaters are often bad heaters2018-06-21
If the water temperature heater is dry, no matter how good the heating tube is, it will be useless.
Why dry burning phenomenon occurs: When the machine is turned on, when the motor and heater are turned on at the same time, the heater will start working immediately: heating will increase the temperature. Since the motor has just started the water and has not yet entered the machine, the heater has no medium of water and causes direct drying. Burning, working for a long time, shortens the service life of the heater, and often makes the heater easily damaged.
Although the circuit board sets up two buttons, namely the motor start button and the heater start button, this requires the operator to start the motor button first, and then wait until the water is completely replenished before operating the heater button. This prevents the heater from drying out. However, because this operation needs to be completed by humans, and the operation is not very user-friendly, it needs to wait for a period of time to continue processing. Many operators often open two buttons at the same time for the sake of convenience, thus failing to achieve the intention of the manufacturer's design. Can protect the heater.
