Question about Rancilio Silvia Espresso Machine

1 Answer

Steam blowing out of group head

Yesterday I cleaned my 3 mo. old Silvia with CleanCaff. Followed the instructions. Bascially ran 4 cups of solution through machine, followed by about 8 cups clean water. It's nice and clean now. But whenever it goes into a heat cycle steam and some water come out the group head, and water also overflows into the holding tray underneath.

    not sure how to describe it other then getting the same problem steam/water whooshes out of the group filter- it does it inconsistently, usually when I pull the first prep shot with no coffee then it's ok- also how often you need to descal and what do you recommend?

Were you using cleancaf to descale? If so, it is not a strong enough descaler. Use Dezcal. or a Dezcal cleancaf mixture. The two work great together.

Make sure you get some descaler in the solenoid area by turning on and off the coffee button.

Hope it works out for you.

I have a Rancilio Silvia around 5 years old. After around a year, it stopped reliably producing dry steam. I have very hard water, but despite regular vinegar cleaning, cannot seem to get it to steam

I work on industrial machines have done so for 15yrs
if your machine is anything like the prof rigs in terms of engineered design then what you are noticing is the pressure release valve working-letting any unused and pressure + water drain from the group head to a small plastic black box below the stainless housing panels/drip tray after extraction is complete.

What i describe should only happen after the shot stopped.

you should hear it and see it the water for about 2seconds after you stop the extraction manually/automatically

Is there a repair manual for the rancillio silvia

There is not a repair manual for the silvia, the most that can go wrong is the 3 resettable thermostat on the top of the boiler, remove the 4 screws on top of the machine for access. Unless you run the boiler dry. Then if the thermostats did not kick off in time then you will need a new boiler. You will notice a discoloration in the water out of the group or the steam valve.

H owdo you clean the machine using the tablet ? Thanks

  1. Turn machine off.
  2. remove group head (portafilter)
  3. place single or dual cup filter in group head.
  4. place rubber bung in group head.
  5. place one tablet in space in bung.
  6. replace group head in machine.
  7. This is where the instructions lead you astray.
  9. Press & hold 1 & 2 cup buttons simultaneously, on their own.
  10. Now press the power button while still holding the 1 & 2 cup buttons.
  11. Cleaning cycle will start, and will take around 5 mins to complete. Book says it will beep 3 times when finished haven't heard this yet. Just wait a couple of minutes extra and all should be well.
  12. Clean me light should be out and tablet disolved if not repeat steps again until tablet disolves.

I have a quite old la pavoni p3v2 110v 2000w two group machine that I have just finished a rebuild on. The machine goes to full temp on the boiler, the steam is great, but I can't get more than about 140...

Check the top of the group head there is a large bolt, within that is the metering jet and filter, that might be the cause of the blockage(either the jet is clogged or the filter is clogged). As for the full temp on the boiler what reading do you get on the gauge boiler side, it needs to be at about 1.2 bars.

Rancilio Silvia is blocked (not completely but substantially. Water is restricted out of both the brew-head as well as the steam-wand. I've cleaned the 3-way solenoid valve and I've run CleanCaf twice....

Your problem sounds like a water pump issue rather than the 3 way valve, try priming the circuit by opening the water valve when you clean the system(if you can find scalekleen, use that instead of cleancaff to descale your machine).

No water thru the group head

We were having the same problem and this worked for us, right from an insert that was included with the manual.

1. Fill tank with water
2. Remove the filter holder
3. open the steam tap
4. press the main switch and the coffee switch at the same time
5. close the steam tap as soon as water begins to flow
6. If after 30 sec. no water comes out repeat the operation.
7. when it starts, draw off 4 cups of water

This worked for us after we had about given up,

Hi ensure that the group head has heated up before using I tend to screw the head in and place the porta filter on top of the machine to allow it to heat up (heat the machine up for at least and with regards to the tamping ensure that you tamp firmly and twist at the end to smooth the surface.You could try tampind the cofee in the portafilter before placing it in the group head then after you have placed the porta filter back in give it another quick tamp remembering to twist at the end to help smooth the surface.

Then pull a shot. I get great crema like this.Also ensure the cups are warm.

You can heat the brew head and cups by running hot water through them before using as well this method is called cheating the Silvia

have a look at this

Hope this helps

No water through the head!!

I had the same problem - all water going down into the tray at the bottom - virtually none through the coffer basket. I couldn't find citric acid at the store to descale so I used white vinegar instead. I 3/4 filled the reservoir with warm water, and added about 1/2-2/3 cup of vinegar. I first ran water through the 'hot water' button (it comes out the steam spout). Then I ran the entire reservoir through the machine using the 2-cups option. It started running right away. I rinsed out the reservoir with fresh water, then ran a whole reservoir of fresh water through the machine to get rid of the vinegar smell. The first cup of espresso after this treatment was as good as ever. Phew! I thought we were up for a new machine!
