The boiler is the preheat reservoir so you don't have to wait. Keep filling the machine untill it won't take anymore and chk for another switch that is always left on at rear side of machine. In =a few second you should hear the water heating Dry run the first time, just have your carafe in place but no coffee, good luck.

My Coffee machine Delonghi doing expresso without foam today. Before doing good expresso with foam. help please.

Espresso should have crema not foam, foam is air added to coffee, like Starbucks does. Issue lays in the grinder and coffee quality. Recommend using Italian espresso bean like Miscela d Oro

Cafe Roma Expresso/Cappucino machine

My understanding is that this is normal with units like the ESP8XL which use a pressurized portafilter. Non-pressurized units will leave a dry puck of used grounds.

Water problem with Expresso maker

Well as i dont know what machine you have I will give you a generic troule shooting for manual esspresso machines.

first if the steam is working one can make the assumption that the way from the watertank to the bioler is ok.

that leaves us with the handle the filter you put your grindend beans in. Or the filter on the machine.

So first trie and see if it comes out water when you dont have on the handle with the espresson filter.

Will water not come even with the handle off? then its the fitler in the machine. trie and remove it and clean it or trie and descale it and force water through the espresso exit.

Will the water come out just fine with the filter and handle off?
then its those two things.
Trie and put the filter in alitle descaling for a couple of hours and the clean it "extremly" good.
