Wenzhou Linnei Water Heater Maintenance Telephone

The national unified 24-hour customer service hotline for forest water heaters is 400- 165-7898. There are gas water heaters, electric water heaters, wall-hung boiler water heaters, floor heating temperature indicator screens (not available in the old ones), gas proportional control valves (not available in the old ones) and so on. With the development of science and the use of some new technologies, some new parts are gradually added. Here are some common parts.

In the case of power supply, water supply and ventilation, due to the pressure of water flow, the microswitch is turned on, the exhaust motor starts to work and exhaust, and the pulse igniter starts to discharge at the same time. The gas control solenoid valve opens the air flow and enters the combustion chamber. When the gas meets the spark, it starts to heat the circulating water tank, and the hot water flows out quickly after the cold water is discharged. If the water temperature is higher than 50 degrees, limit the operation of the thermostat, cut off the power supply and extinguish the gas. If the outdoor wind pressure is too high or the flue is blocked, the circulating water tank will be used for a long time, resulting in melting and adhesion of the heat exchanger of the water tank and poor ventilation, the wind pressure switch will turn off the power supply and the gas water heater will stop working. Usually, the wind pressure switch is easy to break, indicating that the gas water heater can be started, but it will automatically turn off in a few seconds or minutes.

Causes and solutions of flameout of forced exhaust water heater;

Forced exhaust water heater can't catch fire. Reason: 1. Power supply problem.

Solution: check whether the indicator light of AC power plug is on, and first eliminate the problem of power supply.

Forced exhaust water heater can't catch fire. Reason: 2. The solenoid valve is faulty.

Solution: If only the ignition sound is heard during ignition, and the solenoid valve has no magnetic sound absorption, it may be that the solenoid valve is damaged or aging, and the aging solenoid valve will be out of control. At the initial stage of ignition, you can ignite by suction, but then turn it off, turn it off; It may also be that the gas pressure is too high or too low, and the output pressure of the cylinder pressure reducing valve is too high or too low, which will cause the water heater to catch fire; It is more likely that there is dirt on the solenoid valve. If the solenoid valve can't be released, the gas (natural gas, liquefied petroleum gas, artificial gas) can't be released, so it won't catch fire. First confirm whether the igniter control circuit is normal, and then confirm whether the solenoid valve is good or bad. If there is a fault, the solenoid valve can't be controlled to pull in.

Forced exhaust water heater can't catch fire. Reason: 3. The electronic igniter is faulty.

Solution: One of the pulse igniter and controller is faulty, and neither water heater can ignite.

The forced water heater won't catch fire. Reason: 4. Ignition porcelain needle or induction porcelain needle problem.

Solution: A. It is very difficult to ignite when the ignition needle is deviated or aged, so it can be replaced or placed correctly; B. Induction aging can be accomplished by grinding and placing induction needles (so that the flame can fully burn the induction needles no matter whether it is a big fire or a small fire).
