Troubleshooting methods: add the pressurized pump;
Clearing the debris; re-installation of the power supply; Reinstall or replace the new power supply; reinstall the inlet and outlet pipes;
Two, open the water valve after the pulse ignition but not fire
This time, you can check whether the feedback electrode is in the high temperature area of the flame, adjust the feedback electrode height, check the feedback electrode connection lines and plugs;
2, from the window to observe the combination of electrode whether there is a discharge phenomenon.
This time, you can check the combined electrode discharge distance, detection of connections and pulse generator.
E2: Abnormal wind pressure or fan failure
1. When the flue is blocked or the flue resistance is too large, the wind pressure switch operates and the program is interrupted.
At this time, you can check whether the sampling tube connected to the wind pressure switch is connected reliably, there is no air leakage, there is no insertion error, etc.
2. When the fan fails, the rotational speed is too low or stops, and the program is interrupted.
This time, you can check the fan with the main control board between the connecting wire is plugged reliably, whether the fan is damaged, whether the fan is stuck and so on.
E3: Anti-dry burning device action
1, when the thermostat action disconnect, the program interrupt. At this time, you can check whether the connecting wire is connected and plugged reliably, whether the thermostat is faulty, if the thermostat action due to dry burning, you can reset yourself.
2, when the thermal fuse component is disconnected, the program is interrupted.
This time, you can check whether the connecting wire is connected and plugged in reliably, and whether the thermal fuse assembly is damaged due to dry burning.
E4: Temperature sensor failure
The water inlet and outlet temperature probes are disconnected or short-circuited.
This time, you can check whether the connecting wire is connected and plugged in reliably, and whether the temperature sensing probe is damaged.
E5: over-temperature fault The temperature of the water outlet exceeds 93 ℃ for 10 consecutive seconds when ...
