1. Burner defects: If one of the impulse burners and control components is obstructed by one of them, the oil-fired hot water boiler cannot operate.
2. Battery failure: If you use a battery, you should pay attention to whether the battery is too old. Non-compliance of the electric current can also prevent the oil-fired hot water boiler from being ignited.
3. Pressure failure of the water supply: The filter screen at the inlet of the oil-fired hot water boiler becomes blocked and the water cannot flow through normally, so it can be cleaned up.
4. Defects of high-pressure solenoid valve: If the oil-fired hot water boiler only sees the ignition operation sound during the ignition operation, there will be no "click" magnetic absorption sound of the high-pressure solenoid valve. It may be that the high-pressure solenoid valve is damaged or oxidized. The solenoid valve is oxidized and will not be operated. It can be closed once when the ignition is started, and the fire is once fired, but it is immediately closed and then extinguished; before confirming whether the high-pressure solenoid valve has a problem, it is necessary to confirm whether the burner operating element is normal. If there is a problem, the high-pressure solenoid valve cannot be operated.
5. The ignition operation needle or the sensing needle is faulty: the ignition operation needle of the oil-fired hot water boiler is offset. It can be changed or the ignition operation needle can be accurately placed; if the feeling is oxidized, just wipe the feeling clean and place it.
6. The flue cannot be ventilated normally. The flue of the oil-fired hot water boiler has a plug, and the flue is too long for cleaning the plug and the flue is not accurately placed. You can learn from the instructions for the placement of the multi-layer flue of the balanced hot water unit.
7. Defects of water vapor cooperation installation: oil-fired hot water boiler, water vapor cooperation valve inner membrane flap is oxidized or damaged, and cannot promote the micro-power opening and closing device; the micro-power opening and closing device is broken.
