how big are the cups ?
I went google and typed in --how many grams to a cup--- and the following information came up
dry goods
1/2 cup==170 g==6 oz
2/3 cup =227g=8 oz
3/4 cup =255g=9 oz
1 cup =340g =12 oz

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.

You would need a container that's at least 266 2/3 oz so it can hold the original 8 oz and 258 2/3 oz of water (a little more than 2 gallons).

HI
When you run a lot of water through just a little coffee it gets water down. Try making 2 meduim cups instead. When they make espresso its 1 tablespoon to 1 oz of water. Your running 6 oz of water through the same amount of coffee, and its going to be weak. Program you buttons for 2 shots to fill your cup and it will be pretty strong.

If you don't have a calculator to help you with the division by 16, here is a list of all the decimals relating ounces to a pound:

• 1 oz. = .0625 of a pound
• 2 oz. = .125 of a pound
• 3 oz. = .1875 of a pound
• 4 oz. = .25 of a pound
• 5 oz. = .3125 of a pound
• 6 oz. = .375 of a pound
• 7 oz. = .4375 of a pound
• 8 oz. = .5 of a pound
• 9 oz. = .5625 of a pound
• 10 oz. = .625 of a pound
• 11 oz. = .6875 of a pound
• 12 oz. = .75 of a pound
• 13 oz. = .8125 of a pound
• 14 oz. = .875 of a pound
• 15 oz. = .9375 of a pound

Check the thermostat on the side of the boiler, that might be damaged.

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.

you can try descaleing it again ,then go into
the factory reset program and reset it , I had a
similar problem this fixed mine

It could be. Your grind should determine the amount of time that it takes the shot to pour. Standard is 18 - 30 seconds. I prefer 25. If it only takes 10 sec, your crema will be weak.
Are your beans fresh? Older beans produce less crema. By old, I mean more than a month if properly stored.
What is the temperature of you shots? The water coming out of the head should be about 195 F which makes the shots roughly 170-185. If it's too cold, you'll get worse crema. It's also possible to have mostly steam in contact with the grounds which will give the same results. Both indicate other problems.
Make sure your group head screen isn't clogged. And make sure everything is very clean, especially inside the handle (under the grounds basket - just pop it out with a screwdriver). Good luck!
