The water heater is a kind of electric appliance that must be installed in our home, and it is also a common device. It has brought great convenience to our life. However, everyone must have encountered this problem when the water heater does not produce hot water during regular use. I don't know where the problem is. I found that there was no hot water when I went to take a bath at night. What Electric water heater Do you know the reason why there is no hot water? Today, Xiaobian will take you to see why the electric water heater can't produce hot water.
Check whether the tap water pressure is normal. If the water pressure is occasionally insufficient, do not operate the electric water heater. Use the electric water heater after the water supply is normal. If it is found that the water supply pressure is low (the water from other faucets is small), the inlet and outlet valves of the electric water heater can be properly opened. If the opening of the water valve is invalid, the water can be used only after the water pressure is normal. The inspection method is to open other taps on the tap water pipe connected to the electric water heater to see whether the water flow is normal.
If the above method is normal, but the electric water heater still cannot discharge water, it is necessary to consider whether the water path is blocked. At this time, it is necessary to check that the water inlet pipe first closes the main water supply valve, and then remove the water pipe connector. After the water pipe is separated from the electric water heater, open the main water supply valve, check whether the water supply is normal, and check whether the water inlet filter screen is blocked.
If normal water outflow cannot be recovered after the above two inspections, check whether the internal pipeline of the electric water heater is blocked. Before removing the electric water heater, eliminate the phenomenon of no water outflow caused by non substantive faults. The outlet water temperature cannot reach the set value. No matter how high the temperature of the water heater is adjusted, the outlet water temperature is basically unchanged, even hot and cold.
