20 Most Recent Rancilio SILVIA EXPRESSO MACHINE Silvia Home Espresso Machine aka Miss Silvia Questions & Answers

It is possible that the grind you are using is too fine and causing so much back pressure that the portafilter is moving, also possible that the group gasket installed need to be replaced, I have also seen this happen with damaged screens.

It is most likely that something is blocking the pathway to the grinder. As the Rocky is a direct drive grinder there is no gear that could be broken.
Try to remove the beans from the hopper and inspect the pathway, move the beans that might be under the 'disk'. If that is not working you might have to open the grinder;
  • remove all coffee beans
  • unscrew the three screws in the bottom of the hopper
  • remove the hopper
Now you can see the grinder wheel and tell if it is turning normally.
This might be a good opportunity to give the grinder a thorough cleaning.
Do not soak it in water, just a stiff small brush (e.g. a toothbrush) is the best tool. And perhaps accompanied by a vacuum cleaner :)
If you have been using very 'oily' beans for a long time they might have clogged the grinding wheels.

Good luck,

Your pressure steam is more 1.8bar. Either pressustat defective or the safety valve

First, I'm not a Rancilio tech but I have worked on similar models.
*** All service should be performed by a qualified technician. The following is for information only ***
* Usually one gets less water out of the portafilter rather than more (or faster). Check the amount of water on an empty shot. It should be between 1-1/2 oz to 3 oz (depending on your shot size) If this is a manual on/off shot then disreguard.
* Fast pour is directly related to the pressure setting (usually 9 bar), Coffee amount, Grind size, and Tamp (or compression). You can check most of it by following the many examples given on you tube. Water pressure is a bit harder as you will need a pressure guage portafilter.
* If your still having problems with fast shots then have your service vendor check and adjust the bar if needed.

P.S. Check if your using the right portafilter, There are many types used for different purposes; Pod, Capsule, Single, Double, Tripple, Drip coffee (Americano), Back pressure adjustable, ect.

Hi Daren,
You could replace the whole steam valve wand but you don't need to.
The rubber grommet inside the steam valve is worn out and the tap wont close properly - that is why the steam is coming out.
You will find these parts with a commercial rancilio supplier.

You need to contact a coffee technician that deals with Rancilio commercial machines.They would be able to trouble shoot.

But it would involve a call out to investigate the problem.

Hi Ewah,

If you are getting steam from the group and no water when you turn on the water button - then you may have a group blockage.

The fix depends on the type of machine you have.
If it is a commercial type - then call in a qualified coffee technician.
If it is a domestic type like rancilio sylvia, the you could try to descale - maybe too late, but worth a go.JURA descaling tablets
If when descaling, no water is coming from the group try leaving the steam tap open when asking for water.That way you may get the descaler liquid moving inside the boiler and it may clear the solenoid valve blockage.
If no joy with that you may need to replace solenoid valve.
Domestic machines need regular descaling to avoid group blockages.
