Det tycks råda lite delade meningar om hur man bäst handskas med dessa maskiner.
Alla verkar vara överens om att man måste flusha för att bli av med det hetaste vattnet på toppen av kokaren men sedan skiljer sig rekomendationerna åt. Vissa brygger direkt efter flushen medan andra väntar en stund tills vattnet i värmeväxlaren åter nått bryggtemperatur.

"Draw water through the group with the portafilter in place.
Continue until the stream pours steadily for about two ounces (more or less depending on your taste) since the group is still over temperature when the hissing stops. It depends on the machine's pressurestat setting, but in general the water temperature is around 206-207°F when the last of the sputtering subsides. You can literally count "one-one-thousand, two-one-thousand, three-one-thousand" to tick off each degree from that point. To more easily judge when the heat exchanger has emptied of superheated water, keep the portafilter loosely engaged and listen for the sounds of hissing steam and boiling water.
If you've pulled a shot within the last five minutes, you'll need to pay extra attention because the cooling flush will be much shorter than if the machine has been idle for 10-15 minutes (on the order of ¼ the amount of water). You may hear only a brief hiss and that's it. Don't draw too much water or the next extraction will be under temperature (sour).
Remove the portafilter, fill and tamp the basket.
Don't dilly-dally; the water in the heat exchanger will be back to brew temperature in 30-45 seconds.
Lock the portafilter back in.
Recall that a few moments passed as you filled and tamped between the cooldown flush and the beginning of the extraction. This short interval gives the water in the heat exchanger enough time to rebound to brew temperature. I've found it is easier to consistently obtain the desired initial brew temperature by allowing a short natural recovery rather than adjusting the flush amount and starting the extraction immediately thereafter."
