Next, Miss Liu, the coffee maker mall, will talk to you about the maintenance of the semi-automatic coffee machine.

First of all, there must be daily cleaning and maintenance work, which includes the following parts:

1. Coffee machine body cleaning:

Wipe the fuselage with a wet rag before starting up every day. If you need to use a cleaner, please choose a mild and non-corrosive cleaner to spray it on the wet rag and then wipe the fuselage (note that the rag should not be too wet, and cleaning should not be sprayed directly on the fuselage, to prevent excess water and detergent from seeping into the circuit system and eroding wires to cause short circuit).

Clean the water tray and drainage trough after the steam is no longer ejected (note: do not turn off the steam switch at this time, turn off the steam rod when hot water drips out the next day, in order to balance the pressure inside and outside the boiler).

5. Water tray:

If the drainage is poor, pour a small spoonful of cleaning powder into the drain and rinse with hot water to dissolve the coffee residue oil in the drainage pipe.

7. Filter cup and filter cup handle:
