8 Delong 3000Gel 4000 series coffee machine, press the key, sometimes can not turn on, sometimes can not turn off, coffee powder lamp (the light in the lower right corner) will light up for no reason, sometimes the hand touches the coffee powder key, without pressing the button, the light will come on.

Replace the panel circuit board and troubleshoot.

9 automatic coffee machine extractor stuck to the water plate, resulting in start-up can not be up and down, the water plate and extractor can not be taken out

It is estimated that this fault is caused by the customer incorrectly cutting off the power plug, open the back cover of the machine, receive the rotating pulley, make the extractor rise to a slightly higher position, then check the power supply, turn on, and troubleshoot.

10 Delong 3000Gr 4000 series coffee machine, just started to make coffee, the knobs and buttons on the panel function normally, but after making 2-3 cups, the knobs and buttons are confused, such as rotating the coffee powder knob, the water shortage light will always be on.

Replace the panel circuit board, troubleshooting, but carefully observe the working process of the coffee machine, found that the boiler interface steam leakage, estimated steam into the panel circuit board, resulting in panel function failure. Replace boiler seal gasket 5332107700, troubleshooting.

11 extractor can not be taken out, observe that the extractor is at the top. One, two, the alarm light is always on.

After entering the functional test mode, the extractor can move up, but not down. after inspection, the extractor motor is broken, replace the motor and troubleshoot.

The normal voltage at both ends of the motor, when moving up, F8 is positive voltage, F7 is negative voltage, voltage value is 200V, after reaching the top, the voltage disappears and 1 cup light is on. When the 2-cup key is pressed, the extraction part walks downwards, F8 is negative voltage, F7 is positive voltage, and the voltage value is 200V. After reaching the bottom, the voltage disappears and the 2-cup lamp is on.

One cup, two drinks, warning light on.

It may be that the extractor motor is broken, the general motor resistance value is about 200 ohms, if it is too small or open, it should be judged as motor damage. Since this motor is a DC motor, the measuring motor needs to be turned to the motor by hand, and the resistance value is measured in each gear.

If the resistance value is too small, the circuit board may also be damaged, so the circuit board cannot be replaced first, lest the motor burn the circuit board again. If the power is plugged in and the relay sound on the circuit board cannot be heard, it is estimated that the circuit board needs to be replaced.

When coffee comes out of the water, it is dripping, not a current.

After the purchase of the automatic coffee machine, the first few times of use are normal, but after several times of use, the above problems will occur, and check the thickness of the coffee powder is also normal. At this time, it is necessary to check whether there are two pieces of metal filter on the extractor. If there are two pieces, remove one piece, and the fault will disappear.

Q: how many watts of power is consumed in the automatic 3-hour standby time when the current fully automatic coffee maker ESAM series is powered on?

A: there is a conceptual error. Watts are units of power and cannot be used to measure power consumption.

If what you want to ask is, during the three hours of automatic standby, how much power was consumed by the original ESAM series machines, I can say very small. Because for example, a 1350W coffee machine works continuously for an hour and consumes 1.35 kilowatt-hours of electricity. If it is only standby, the power is only 0.5 watts / H.

Q: when the automatic coffee machine uses coffee powder to make coffee, can it adjust the intensity?

A: the thickness of coffee is caused by three factors, the thickness of coffee powder, the amount of coffee powder and the amount of water. You can increase the concentration of coffee by choosing fine coffee powder, using more coffee powder and a small amount of water, on the contrary, coffee tastes light.

Q: why do I use the foam function? the effect is always bad.

A: high quality milk is recommended and refrigerated in the refrigerator.

Handle failure of all semi-automatic coffee machines

Failure phenomenon:

1. Why the new coffee is so noisy: first make sure that the coffee tank has been installed and add water to the tank, then turn on the hot water knob to release water and exhaust in the power-on state, which can be eliminated after the water comes out smoothly. Specific methods can also call the toll-free service telephone number: 6968-669

two。 If the handle is not installed, it will not come out of the water. if the pump works, it is estimated that there is something wrong with the spring at the bottom of the boiler and the plastic top column.

3. The handle and coffee powder can not produce water, but the empty handle can produce water. It is estimated that the coffee powder is too fine or pressed too tightly.

4. Water does not flow from the bottom of the filter shown in figure 1, but overflows from the edge of stainless steel. It is estimated that the spring and the top column in the middle of the plastic sheet shown in figure 3 are blocked by coffee grounds and cannot move freely. Press the top column of the red arrow by hand and rinse in clean water to remove the coffee grounds and restore the function of the handle.
