4. Common faults in water pressure problems: there is a ignition sound and spark, but it will be extinguished quickly when it is burned. Solution: Turn on the faucet to check whether the water pressure is too small. If the water pressure is too small, then there is only the only way to stagger the peak water use period. However, if there is blockage, it will also cause the water to not flow normally. At this time, it needs to be cleaned. 5. Common faults for valve seals being corroded by gas: there is a ignition sound, but no electric sparks may be because the valve seal is corroded by gas. Solution: If the valve seal is corroded by gas, it is necessary to replace the corresponding parts, that is, replace it with a new seal . 6. Common faults for smoke exhaust pipes that cannot be exhausted: there is a ignition sound and electric sparks, but it goes out quickly, which means that the smoke exhaust pipe cannot be exhausted. Solution: Check whether the smoke pipe is blocked. If so, clean the smoke pipe in time. With people's economic level now, the requirements for quality of life are getting higher and higher, so they will use various household appliances, such as water heaters. Note: gas water heater shows that ee faulty gas water heater is water-controlled and has water flow requirements. This requirement is not met. The water heater cannot release gas and turn on igniter , and cannot be used. It is recommended to check the situation of hot water faucet . If it is smaller, it may be a problem caused by insufficient water flow. Cold water is normal and hot water is small. You should consider why the hot water used to be large, but now the hot water is small. The reason is that the scale deposits are increasing, and the pipeline is blocked. The water flow does not meet the conditions, and the water heater cannot ignite. Service area: There are service outlets in the city's joint districts* dispatch orders nearby.
gas water heater can be used immediately and is loved by many people, but any machine will have certain problems when working for a long time, and gas water heater is no exception. If it has a long service life, some failures may occur. Today I will help you sort out some common failures and solutions for gas water heater.
Common faults of gas water heater
Fault 1: In use, shut down
During use, there is a fire out during use. You can check it according to the following procedures:
a. Check that the gas valves are not all opened. If not, you need to open all gas valves .
b. After turning on, you can turn on and off the hot water to heat until it catches fire. Because the gas pressure is not appropriate, too low will also cause the combustion to stop during use.
tip: The process of switching hot water switches requires waiting for 5S or more before turning on.
c. Ask professional maintenance personnel to check the water pressure, because the fault may be because the water pressure for cold water supply is too low. If the water pressure is 0.035MP, in this case, adjust the water volume control screw under the gas valve body and reduce the water output a little.
d. In addition to the above items, the maintenance personnel need to be asked to clean the carbon deposits in heat exchanger . If the water controller or pulser fails, the maintenance personnel will handle and replace it. It is also necessary to check whether the leads are loose, whether the solenoid valve , and whether the flame probe is faulty, these are all possible reasons for the flame out during use.
fault 2: The water heater cannot fire
This situation occurs. The processing method is somewhat similar to the processing method of fault 1. Let’s briefly talk about the method of handling this situation.
a. Open all valves
b. There may be air in the gas pipe . Continuously switch the hot water to control the switch until it catches fire, and drive the air out.
c. Check the main valve for cold water supply and open it.
d. Check whether the water pipe is frozen. If it is frozen, you need to wait until it melts before use.
e. The water pressure for cold water supply is too low, check the water pressure. If these are all fine, check the power supply to see if the power supply contact is complete, or some use to dry the battery , is it because the battery is out of power, if it is not powered, just replace the battery.
f. In addition, there are problems such as water controller or pulser, lead wire, micro switch, solenoid valve failure, and battery positive and negative poles. Fault 3: The flame has yellow smoke and
The cause of failure: burner is blocked or the heat exchanger is blocked
treatment method: Maintenance personnel are required to clean up the debris in the burner and the carbon deposit in the heat exchanger.
fault 4: abnormal flame with odor
cause of failure:
1. Insufficient supply of fresh air.
treatment method: immediately improve ventilation so that it has enough fresh air.
2. The burner is blocked.
Processing Method: Maintenance personnel clean up the debris in the burner.
3. The heat exchanger is blocked.
treatment method: Maintenance personnel clean up the carbon deposit in the heat exchanger.
fault 5: There is an abnormal sound during ignition
cause of fault:
1. The gas pressure is not appropriate and it is too high.
treatment method: Continuously switch hot water until it catches fire.
2. Insufficient supply of fresh air.
treatment method: immediately improve ventilation so that it has enough fresh air.
3. The burner is blocked.
treatment method: Maintenance personnel clean up the debris in the burner.
Fault 6: Adjusted to the high temperature position, the water is still not hot,
Reason for the fault:
1. The gas valve is not open all
. Processing method: Open all valves
2. The gas pressure is not appropriate and is too low.
treatment method: Continuously switch hot water until it catches fire.
3. The water temperature regulation method is incorrect.
treatment method: refer to the hot water temperature adjustment
4 in the instruction manual, the water controller fails.
processing method: Maintenance personnel handle
fault 7: The water is too hot in the low temperature position
cause of failure:
1. The water temperature regulation method is incorrect.
treatment method: refer to the hot water temperature adjustment
2 in the instruction manual, the water controller fails.
processing method: maintenance personnel handle it.
fault 8: The fire is extinguished in low temperature position
fault reason: The water pressure of cold water supply is too low.
Treatment method: Maintenance personnel check the water pressure.
fault 9: The fire does not extinguish after closing the water heater
fault reason: The water controller fails.
processing method: maintenance personnel handle it.
3. Common faults of electric igniter: There is no ignition sound or electric spark, which means that the electric igniter may have failed. Solution: Check whether the pulse igniter and controller of the water heater are faulty. In the case of fault, it needs to be replaced or repaired in time. 4. Common faults in water pressure problems: there is a ignition sound and spark, but it will be extinguished quickly when it is ignited. Solution: Turn on the faucet to check whether the water pressure is too small. If the water pressure is too small, then there is only the only way to stagger the peak water use period. However, if there is blockage, it will also cause the water to not flow normally. At this time, it needs to be cleaned. 5. Common faults for valve seals being corroded by gas: there is a ignition sound, but no electric sparks may be because the valve seal is corroded by gas. Solution: If the valve seal is corroded by gas, it is necessary to replace the corresponding parts, that is, replace with a new seal. 6. Common faults for smoke exhaust pipes that cannot be exhausted: there is a ignition sound and electric sparks, but it goes out quickly, which means that the smoke exhaust pipe cannot be exhausted. Solution: Check whether the smoke pipe is blocked. If so, clean the smoke pipe in time. With people's economic level now, the requirements for quality of life are getting higher and higher, so they will use various household appliances, such as water heaters. Note: Gas water heaters show that ee faulty gas water heaters are water-controlled and have water flow requirements. This requirement is not met. The water heater cannot release gas and turn on the ignitor, and cannot be used.
