Question about Rancilio Silvia Espresso Machine

I am wondering what the blind diaphragm is for. The coffee seems to be running out too quickly and there is very little crema. I have played with the grind and the tamping.

The blind filter is for back flushing the grouphead, try adjusting the grind finer.

Dispenses very little CREMA. Is there something to adjust?


Rule of thumb - espresso machines deliver a shot of coffee in 25 to 35 seconds.

If there is no crema and the coffee comes faster:
  1. There is not enough coffee in the portafilter (7 grams per shot).
  2. The coffee is not tamped enough (about 30 lb pressure on the tanmper handle).
  3. The grind is too coarse.
If the above does not "fix" the crema problem, post again and include make and model of the machine and type of portafilter.

Good luck.

I do not know how to use the Blind Diaphragm filter


The blind filter is used to backflush the group with espresso machine soap to get rid of the coffee oils.

SAECO fully auto Traditional Very little crema


The crema is created by reducing the grinding to more fine so the coffee will run slower around 20 sec. Inside the coffee bean container their is un adjust control and with special tool you can turn it to grind the coffee to more fine.

I have a Krups burr grinder and I am wondering what setting I should use for the 800ESXL?


Hi,

Really, this is personnal, but first you have to acheive an adjustment that makes your coffee possible to extract. Start with the coarser you can and reduce gradually. Do it one portion at the time, don't grind a whole bag !
The result should be a light hazelnut crema color, deep foam without hole in it.
If the crema is light cream color, the grind is too coarse.
If the crema is dark, uneven or runny, the grind is too fine, or you are using a wrong type of coffee (like only robusta, go for 100% arabica), or it's not toasted properly.
If the water doesn't flow at all, your grind is too fine.
It should take not more than 20 seconds to extract the coffee, if it's very short, grind is too coarse, if it takes longer, the grind is too fine.

Good luck,

JF

Why doesn't my Krups espresso maker produce crema when I brew espresso? Very little is produced and gets blasted away by the time it's don't brewing.


Crema is the goldish brown top that goes onto the top of the coffee once it is dispersed from the espresso tap and flows naturally as part of the coffee when coffee is made. Im not sure what you mean "blasted."
Perhaps you should flush through the machine with cold water a couple of times beforehand and also consider a descaling kit - check your manual or Krups if there is one for this model.
Crema isn't produced by any machine though.

Weak coffee and pale crema.


If you get weak coffee from espresso machines:

Check water temp, if water temp is insufficient , most common is scale heating element , faulty element, faulty thermostat.
Check if water is dripping right at the center of the filter, if it is dripping on one side because the orifice is clogged, that can result in weak coffee.
Coffee blend not well distributed on filter basket.

On Espresso machines:

Check water temp, same as filter coffee machines (thermostat element, scale on heating chamber).
Ensure that coffee is filled correctly in the filter cup (fill at level), and well pressed.
Ensure that the coffee mixture that you are using is not too coarse, buy the apposite one for espresso.
Ensure that you are not leaving the machine brewing for a time that is too long, and Italian coffee cup is very small, approximately one regular shot.

On the hob moka pots (espresso, Moka and Bialetti type):

This are the trickiest ones, you need art and practice to get a good espresso with a Moka, but when you learn, the result is better than what you may get with an home electrical espresso maker.
The frame on the hob must be not too strong, and the mixture coarse but well pressed, with water at level tag, or you will get a weak coffee.
On Mokas a good strategy is keeping hob at minimum, and turning up the flame at top when coffee starts coming out.


Note: insufficient pressure and clogged lines on electric machines never give you a weak coffee, exactly the opposite.
Not pressed mixture always gives weak coffee, but too much pressed mixture may give you coffee with bad taste.
