Sorry, my gas water heater won't ignite without hot water.
First, there is something wrong with the power supply.
Gas water heaters need batteries. If the battery is not replaced for a long time, the battery will be dead or short of power. At this time, the voltage will be insufficient and the water heater will not catch fire, which is also the most easily overlooked problem.
solution
You need to check whether the indicator light of the AC power plug is on first. If the battery doesn't work, please replace it with a new one.
Second, there is something wrong with the solenoid valve.
The electromagnetism of gas water heater may be damaged or aged. If used, it can catch fire, but it will go out soon. This situation is always caused by aging. And if it is damaged, it won't catch fire.
solution
Replace the solenoid valve or clean the solenoid valve in time. The solenoid valve is blocked by dirt during long-term use. If the gas is blocked, the gas can't get through, and then the gas (gas, liquefied petroleum gas, artificial gas) can't get out, and of course it can't catch fire.
Third, the water pressure is too low.
The water obstacles of gas water heater mainly include blockage of water inlet filter screen, scaling of water valve, deformation and blockage of copper pipe in water tank and low water pressure. The same point that they cause the gas water heater to fail to catch fire is that the water output of the water heater will be obviously reduced, and the water heater cannot be started when the starting pressure of the gas water heater is as low as 0.02MPa, which is more obvious in the old exhaust water heater.
solution
Just observe whether the water output or water pressure is too low, and if it is found to be too low, follow the previous steps. The circuit system of the water heater is faulty, the water heater does not ignite, and the gas water heater does not ignite. The central part of the search includes leakage protection plug, water heater power control box, pulse ignition, electromagnetic valve, fan starting capacitor, fan, wind pressure detection switch, micro-switch water flow sensor switch, ignition needle, induction needle and cold and hot switch.
Fourth, the water temperature is not enough
The water temperature of the water heater is not a very common problem. The reason for this is that the load of the machine is not enough. Take 10L blower as an example, and its approved value is 1 min to heat 10L water to 5 degrees Celsius. However, the water temperature in winter, and the water pressure of ordinary families reaches 1 minute, 10 liter, which is usually 6-7 liters, plus the water temperature, so it can only be heated to a certain temperature. ?
solution
First, multi-liter multi-water heater, such as 10 liter water heater needed by ordinary families; Second, close the small water intake; The third is to check the water pressure. If the water pressure is lower than the water demand when the gas water heater is started, it is recommended to install a booster pump.
