Weineng displays F28 or indicates abnormal natural gas supply, so it is necessary to check the gas supply inside the boiler.
The solution is as follows:
1. Check whether the gas valve of the natural gas supply boiler is open. If the operation is not normal, please continue to the next step.
2. Check whether there is enough balance in the gas meter. If there is no balance in the card, please pay in the business hall or by other means.
3. The flame situation is detected by the ignition of the cooker, and it is not necessary to indicate the gas off.
4. The natural gas supply is normal, and then press the gas reset button (marked "Flame Crossing") to restart.
If this method can't solve the problem, you need to find a professional from the manufacturer to check whether the gas valve is blocked or damaged and replace it.
