The filling and boiling device of coffee machine is the core component of making coffee, which is mainly composed of water tank, pump, heater, valve and water storage tank. If the filling boiler of the coffee machine fails, it will seriously affect the quality of coffee making and even make the coffee machine unable to continue to use. The following are the common reasons for the failure of the filling boiler of coffee machine.

1. heater failure: the heater is a key component for heating water. If the heater can't be heated or the temperature is too high, the coffee machine can't work normally. The causes of heater failure include power damage, burning of heating elements, failure of temperature control system, etc.

2. Pump failure: The pump is the key component to send water from the water tank to the filling boiler. If there is something wrong with the water pump, the water pressure is insufficient or does not flow. The main causes of pump failure are internal parts damage, blockage, power supply problems and so on.

3. Valve failure: Valve is the key component to control water flow. If the valve cannot be opened or closed, it will lead to poor water flow or overflow. The causes of valve failure include valve damage and circuit failure.

4. Water tank or water storage tank failure: The water tank or water storage tank of the coffee machine is a part filled with water. If it leaks or is damaged, the coffee machine will not work properly.

5. Other faults: such as machine overheating, water shortage, control circuit problems, etc.

Summary: The troubles of the filling boiler of coffee machine mainly come from the problems of heater, pump, valve, water tank and water storage tank, which need to be repaired in time. At the same time, you should follow the instructions and precautions of the coffee machine, keep the machine clean, and clean and maintain it regularly.
