I designed it, and the most recent course was to design a coffee maker. But I haven't used a coffee maker. I don't know what problems I'll encounter in the process of using it. Or how does it satisfy itself?. Thank you Under the knowing answer.

Then I suggest you understand the construction of the coffee maker first, but it seems that the problems are often not enough. If you understand the basic structure of coffee machine, even on the inside of the details are not very understanding (part of the country is simply do not come out of production), you can know the whole is how to design it, and reflect the problem in terms of relatively easier. Personal view!
1 after the coffee machine is switched on, the warning light is always on, and the machine doesn't work:2, coffee water can not be adjusted, water shortage lights flashing, but you can make coffee, hot water after the lack of water does not light, but after the completion of a cup of coffee, water shortage lights flashing.3 steam, no steam, later, water shortage indicator flashing:4, if the machine has been grinding bean mill powder, water pump began to work, making coffee, suddenly pulled out of the water tank, the heater will occur thermal protector, easy to damage5 boot, long time no Ready information, and finally GENERICALARM.Fracture fixed extractor for the 6 pillar housing components7 press the key, and sometimes can not turn on the machine, and sometimes can not shut down, coffee powder lamp (the lower right corner of the lamp) will be lit up without reason, and sometimes hand contact with coffee powder key, not button, the light will also be bright.8 automatic coffee machine extractor stuck water tray, which cannot boot from top to bottom, the water receiving tray and extractor are not taken9 coffee when the water into a drip, not into the water, you know so much, and I hope to help you oh,
