1. Daily cleaning and maintenance:

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 spray it on the wet rag and then wipe the fuselage with a mild and non-corrosive detergent (note that the rag is not too wet. Detergent should not be sprayed directly on the fuselage to prevent excess water and detergent from infiltrating into the circuit system to avoid short circuit caused by wire erosion.

two。 Outlet of the brewing head: after each production, remove the handle and press the cleaning button to remove the coffee residue left in the brewing head and on the strainer. Then insert the handle into the seat (note: do not tighten the handle at this time) press the cleaning button and shake the handle left and right to wash the head washer and coffee grounds on the inside of the head.

3. Steam stick: after using a steam stick to make milk foam, you need to wipe the steam stick with a clean wet rag and open the steam again. The key is to clean the residual milk dirt in the spray hole with the force of the steam itself and at high temperature to maintain the smooth flow of the air hole. If there is residual milk crystallization on the steam rod, soak the steam rod in a steel cup filled with 8% hot water to soften the crystallization in the jet hole and on the steam rod, remove the steel cup after 20 minutes, and repeat the operation in the first paragraph above.

4. Boiler: in order to prolong the service life of the boiler, if the machine is not used for a long time, please turn off the power supply and turn on the steam switch, the pressure in the boiler is completely released, wait for the boiler pressure gauge to indicate zero, and then 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, and then turn off the steam rod when hot water drips out the next day to balance the internal and external pressure of the boiler).

5. Water plate: remove the water plate before opening or before use, scrub it with a clean water dishcloth, wait for drying and install it back.

6. Drain trough: remove the water tray, clean the sediment in the drain with a wet rag, and then wash it with hot water to keep the drain unblocked. If the drainage is poor, pour a small spoonful of cleaning powder into the drain and wash it with hot water to dissolve the coffee residue oil in the drainage pipe.

7. Powder bowl and powder bowl handle: wash the handle with hot water at least once a day to dissolve the coffee oil and precipitation left on the handle so as to prevent part of the oil and sediment from flowing into the coffee during cooking, affecting the quality of the coffee.
