This is an old-fashioned water heater that is relatively simple to make. If water is still supplied after the water is filled, the water will overflow the return pipe. However, many water heaters are now fully functional and have automatic settings when the water is full, they will automatically stop adding water, so there will be no water overflow from this type of water heater.
If the water heater's water tank overflows, it means that the water heater is defective, usually for the following reasons:
< /p>
1. The most common reason is: A common cause is probe failure. If the probe fails, when the water tank is full, the signal returned by the probe to the instrument is still not full, and the solenoid valve is still open and continues to fill the water, and the Water can only overflow into the air. Holes. Disconnect the power supply. If the resIf the water does not overflow, this means that the probe is malfunctioning. The solution is to replace the probe.
2. If the water tank continues to overflow after disconnecting the power supply, turn off the cold water switch in front of the solenoid valve. If the overflow stops, it means the solenoid valve is faulty. The solution is to replace the solenoid valve.
3. Unplug the power, turn off the cold water switch and turn off the hot water outlet switch to avoid water overflow. This indicates that the mixing valve is faulty and requires. To be replaced. In fact, the flowing water will not affect the normal use of the solar water heater, but it will still be harmful after a long time and waste the waters, so if there is any fault, it must be repaired in time.
