Delong coffee machine always shows what is the problem of water shortage? introduction to the instruction manual.

Desiderio Pavoni obtained a design patent for Bezzera in 1903, and he has been making the coffee machine since 1905. After that, Teresio Arduino began to produce similar coffee machines, and other producers followed suit. In the 1920s, coffee shops in Italy could see signs of this kind of coffee machine. But the Italians are obviously not satisfied with the results of the steam pressure coffee machine. The pressure should be increased by steam, but increasing the heat may burn the coffee powder during cooking, losing the aromatic oil hidden in the coffee powder and making it more refined.

Take out the doubly bitter coffee. Therefore, some people think: can it be directly pressurized on the hot water instead of boiling the water with steam as the pressure?

During the two world wars, people used the natural pressure of water from the faucet to increase the pressure of brewing coffee. The coffee machine uses electricity to quickly heat a small pot of water to the boiling temperature, each pot of water to make a cup of coffee, each pot connected to the faucet. As long as the operator gently press the pole on the small pot, the pressure of the faucet will push the hot water in the small pot to the coffee powder. According to the difference of water pressure in different regions, generally speaking, the pressure generated by this coffee machine is greater than the 1.5 atmospheric pressure produced by the steam pressure coffee machine. The height of this coffee machine is not too different from that of the steam pressure coffee machine, but the overall size is smaller. In appearance, it was more in line with the popular trend of the late 1920s and 1930s, replacing the arc of the steam pressure coffee machine with straight and geometric lines.

The warning light is always on and the machine does not work after the Delon 3000 gamble 4000 series coffee machine is turned on.

After entering the test mode, start the motor, the motor has a slight action, but does not work. After inspection, the bridge stack on the circuit board (rectifier bridge) is damaged, replace the bridge stack, troubleshooting.

2 Delong coffee machine 3000, 4000 series, fault: the amount of coffee can not be adjusted, the water shortage lamp flashes, but it can make coffee, after putting hot water, the water shortage light is not on, but after making a cup of coffee, the water shortage lamp flashes again.

The water meter is broken

3 release steam, no steam, later, the water shortage indicator flashes.

There may be something wrong with the pump

4 if the automaton bean grinder has finished grinding, the water pump starts to work to make coffee and suddenly removes the water tank, what will happen, what accessories will break down, and how to deal with it.

The water tank should be put back and hot water should be released.

The thermal protector of the heater is easy to damage.

5 Delong coffee machine 3500 6600, after being turned on, there is no Ready message for a long time, and finally GENERICALARM appears.

Check if there is heat in the warm cup area.

Usually the heater doesn't work, check the temperature protector.

6 as the customer did not completely shut down the case, the extractor will be forcibly pulled out, and forced installation, but the water plate is not in place, how to solve the fault without dismantling the machine?

Unplug the power supply

Manually reset the coffee grounds and door switch

Switch (the power) on

Automatic reset of extractor
