5.How does this machine work?

Looks like a generic combined espresso and drip coffee machine. You can operate both or 1 at a time. Recommend that you do either drip or espresso. For the espresso fill in water from an RO machine or bottled water as tap water may have a high mineral content which will clog the machine. I am not sure if this machine has a combined tank or individual tank for both machines. Anyway fill in the tank. As the portafilter looks non standard fill about 14 grams of finely ground coffee, tamp it and run the machine for about a minute to extract 120 ml espresso. Put on only 1 switch, the one in the right. This machine also has a steam attachment and you can steam milk in a jug by using the knob on the top or on the right.

For the second machine open the top and put in about 30 gms of coffee, in the filter( it may have a removable mesh filter or you can use a size 4 paper filter) . Fill in 500 ml of water in the water tank and wait for the coffee to drip down in the carafe. I may warn you that this looks like a cheap non standard coffee machine. If you really want good coffee buy a branded drip machine or pump espresso machine separately. You also need a good burr grinder. If you are not sentimentally attached to this machine just junk it or gift it to your worst enemy
