How to deal with the problem or blockage in the brewing group of the coffee machine? Basic troubleshooting methods of coffee machine

Abstract: coffee machine installation-maintenance-maintenance-after-sales part: this paper mainly introduces the Chinese translation of English display of some common faults encountered in coffee machine, as well as the troubleshooting methods and other related knowledge points.

1. Trouble Tips and troubleshooting methods of Coffee Machine in English

Many high-end fully automatic coffee machines have a display screen, most of which are displayed in English because of technology and various reasons. It is especially a headache for domestic coffee machine users. Here, we will provide you with the English display and troubleshooting methods of some common coffee machine failures.

BREW UNIT BLOCK

There is a problem or obstruction in the brewing group. Need to clean and check and return to position.

BREW UNIT MISS

There is an error in the brewing group. Not installed or the service door is not closed.

COF. BEANS EMPTY READY FOR USE

No coffee beans, add coffee beans and restart the machine.

DESCALE READY FOR USE

The bean dregs tank is full. Clean up the bean dregs trough.

DREGDRAW MISS

The coffee residue box is not in place and jammed tightly.

DREGDRAWER FULL READY FOR USE

The bean dregs tank is full. Clean up the bean dregs trough.

ENERGY SAVING

Power-saving device activated, standby. Just press ENTER gently.

FELL COFFEE BEANS READY FOR USE

No coffee beans. Restart the machine after adding coffee beans.

FILL WATERTANK

There is no water in the tank.

GRINDER BLOCKED

There's something wrong with the bean grinder. Need to clean the bean grinder, or contact the maintenance personnel.

OVER TEMPERATURE

Let the machine drain again.

VENTILATE

If there is no water in the water tank or internal waterway, drainage must be done before the boiler is heated.

WARMING UP

When heating the boiler, wait about 3-5 minutes until "SELECT PRODUCT" and "READY FOR USE" are displayed.

two。 What if the filter of the coffee machine is blocked?

Just rinse the strainer.

Cleaning of filter screen

1. Use the handle of a spoon against the edge groove of the filter (do not use a sharp instrument) and pry down at different angles until the filter falls off. (the same method on the left and right)

two。 Put the filter screen, sealing ring and cannon handle into a clean slag tank, add 30 grams of special cleaning powder for coffee machine, then soak in 900 ml of boiling water for 20 minutes, then rinse with clean water.

3. After washing the filter screen, sealing ring and gun handle with clean water, put it into a clean slag tank, soak it with boiling water for one night, and install it on the brewing head the next day.

Note:

For the installation of the brewing head, put the sealing ring up on one side of the word, put it flat on the filter net, then put it into the handle strainer of the brewing head, and finally install the handle straight on the brewing head. (do not tilt, straight and hard to the top, counterclockwise needle rotation handle)

3. Basic troubleshooting methods of coffee machine

2, boiler water shortage: 1, external water supply is off 1, check external water supply 2, machine automatic water supply system is not turned on 2, turn on machine water filling system 3, filter blockage 3, replace filter element 4, pump motor card main 4, check pump 5, pump motor fuse 5, check fuse

3. Too much water in the boiler 1, too dirty solenoid valve into the boiler 1, cleaning or replacing the solenoid valve

2, heat exchanger perforation 2, if possible, replace heat exchanger 3, water level probe or weak ground contact is not good 3, reconnect

4. no steam in the steam nozzle 1, raise the water level of the boiler 1, check the water supply system

2. the pressure switch is broken. 2. Replace the pressure switch.

3. Problems with the heating safety device 3. Check the heating safety device (if any)

4. Nozzle blockage 4. Clean up

5. Coffee cannot be extracted 1. Water shortage in the system 1. Check the water supply system.

2. Head solenoid valve damage 2, replacement head solenoid valve 3, pump jam 3, check pump 4, control fuse burn 4, replace fuse 5, nozzle clogging 5, cleaning nozzle 6, head solenoid valve clogging 6, cleaning head solenoid valve

6. Machine leakage 1, drainage pipe clogging 1, cleaning drain pipe

2. Break the water pipe. 2. Replace the drainage pipe.

7. Low espresso temperature: 1. Burnout of electric heating rod. 1. Replacement of heating rod.

2, wire connection error 2, check wire connection 3, too much scale in heat exchanger 3, descaling

4. Pressure switch aging 4, change pressure switch 5, thermal cycle blockage 5, check thermal cycle

8, espresso temperature is high: 1, the pressure switch is adjusted too high 1, adjust the pressure switch

2. Coffee powder is too fine. 2. Adjust the size of the grinding powder.

9, coffee flow rate is too fast: 1, coffee powder is too coarse 1, adjust the size of the grinding powder

2. The machine temperature is too high. 2. Check the machine temperature

10, the coffee flow rate is too slow: 1, the coffee powder is too fine 1, adjust the grinding powder thickness

2. Handle filter cup is too dirty 2, cleaning filter cup 3, head solenoid valve blocking 3, cleaning or replacement 4, internal blocking of machine head 4, checking head assembly 5, nozzle blocking 5, cleaning nozzle

11, coffee powder is too wet: 1, the head solenoid valve is not closed tightly 1, check the solenoid valve

2, the temperature is too low 2, waiting for the temperature to rise to the standard value 3, coffee powder is too fine 3, adjust coffee powder thickness 4, thermal cycle blockage 4, check thermal cycle

12. The pressure gauge can not display the pressure correctly. 1. The display position of the pressure gauge is incorrect. 1. Change the pressure gauge

13 all panel lights flashing: 1, do not add water within 2 minutes 1, check the water supply system
