Case of after-sales maintenance of forest wall-hung boiler: common fault solutions

1. Water shortage fault of wall-hung boiler pipeline

When the fan and water pump of the wall-hung boiler do not work, the fault code displayed on the display screen is that the pipeline is short of water, and the controller gives an alarm.

Sometimes it must be because the power cord of the water pump falls off and the water pump is not locked for a long time, which leads to the failure of water shortage in the wall-hung boiler pipeline;

At this time, use a multimeter to test whether the output power of the water pump is normal and whether the contact is good. If the controller has no voltage

The output is controller failure, replace the controller; If the controller has voltage output, the water pump has no electricity and the connector falls off contact.

Bad or broken wires; If you drop it, contact me again. If the contact is not good, I will contact you again. If the wire is disconnected, it will be replaced.

If the water pump has voltage input, and the water pump does not turn, it may be locked. Unscrew the slotted screw on the water pump and use the slotted screw.

The screw cutter rotates the shaft of the water pump to make the rotor of the water pump rotate and return to normal; If the water pump is not locked, use a multimeter to detect whether the water pump is damaged.

Road or short circuit, water pump burned out, replace the water pump.

2. The ignition of the wall-hung boiler failed.

When the igniter of the wall-hung boiler ignites normally but does not ignite, and the display screen shows the ignition failure code, the main controller gives an alarm.

Sometimes it must be because the insulating porcelain of the ignition needle is damaged or the metal needle is loose that the ignition spark is weak and the power supply of the air valve is different.

The solenoid valve often won't open. The ignition current adjustment of proportional valve is unreasonable. Small fire of sectional valve and unreasonable gas flow adjustment. flammable gas

There is a foreign body in the valve, which leads to poor starting. Bad rubber tympanic membrane of proportional valve. The electromagnetic coil is damaged (short circuit or open circuit).

Gas pressure is too high or too low. High and low speed line connection of two-speed fan. The related parameters of ignition needle are incorrect; Maintenance party at this time

The method is that the pipeline lacks water to replenish water; If the pipe leaks, try to stop it. Test with multimeter, if the pressure switch

If not, replace the pressure switch; If the contact is poor, reconnect; If the line is open, replace the wire; If inserted

The wrong terminal is connected correctly. Drain the piping system.

4. Unexpected flameout of the wall-hung boiler

When the screen of the wall-hung boiler shows the accidental flameout fault code, the main controller gives an alarm, and the flame goes out after ignition. The general reason is that

It's carbon deposited by a flame induction needle. The connecting wire of the flame induction needle has poor contact. The suction and exhaust ports are blocked or the flue inlet is not extended.

Outside the wall. Downward flow outside is too strong. The supplied gas pressure is abnormal, too high or too low. Controller failure. The flame sensor pin is not connected.

Touch the flame. The flue is not installed correctly. Put the intake and exhaust pipes in the flue. Ground wire falls off or is open. Maintenance party at this time

The method is to remove the carbon deposit on the flame induction needle. The connecting wire of the flame induction needle is well connected. Clean the suction and exhaust ports to realize suction and exhaust.

Smooth. Change the position or direction of intake and exhaust. Adjust the gas pressure to the rated gas supply pressure. Replace the controller. Light the fire

The flame induction needle is adjusted to the position where it can contact the flame in case of fire or small fire. Preferably, it is the junction of the inner flame and the outer flame of the flame.

It is forbidden to connect the intake and exhaust flue to the public flue and move it outdoors. If it is normal to remove the smoke pipe, it means that the smoke pipe is not connected properly.

Reconnect the smoke pipe.

5. Wind pressure fault of wall-hung boiler fan

When the controller of the wall-hung boiler gives an alarm, the display screen shows the fault code of the wind pressure of the fan, and the fan does not run or runs slowly.

The general reason is that the fan is stuck or burned out; Poor contact of connector; Controller failure; Capacitance damage; The supply voltage is too low. this

The maintenance method is to open the circuit to replace the fan when using the multimeter to detect the fan, and replace the fan if it is stuck. The poor contact of the connector is serious.

The new connection has been inserted. Controller failure Replace the controller. The fan impeller can be pulled by hand, and the capacitor will be damaged if it can be started. Replace the capacitor.

. Install a voltage regulator to increase the power supply voltage to 220 volts.
