Probably because the hot water valve didn't open. Check whether the valve is open. If it is, it may be because the gas supply is interrupted. Check whether the gas pipeline is normal. If these are all right, you need to check whether the controller or hot water valve of the water heater is faulty, and you need to contact professional technicians for maintenance.

Gas leakage is a very serious fault, which requires immediate measures. Close all gas valves and power switches, immediately notify the local gas company and contact professional and technical personnel for handling.

If the water heater makes noise, it may be because there is air in the water heater. It is necessary to open the exhaust valve to release the gas in the water heater. If there is still noise, it may be that the water heater has some foreign objects or scratches, which need to be cleaned and checked.

If the water heater doesn't work at all, it may be because of power failure. Check whether the power supply is connected correctly. It is also possible that the controller of the water heater is out of order and needs to contact professional technicians for maintenance.
