Question about Rancilio Silvia Espresso Machine

3 Answers

Our Rancilio Silvia is producing really bad tasting coffee of late...my husband thinks that it is old water but I think it may have something to do with the fact that it has been leaking from the steam wand. Maybe an old seal is melting and creating this flavour or maybe it needs a serious internal cleaning?

Hi cstanphi,

Bancheracer is very likely to be right!
I never have to clean my screen this way. Every time I brew coffee, I pump a half cup of water trough the empty filter, simultanousely with grinding the beens.

This keeps the filter as well as the brew head screen permanently clean very easely, but quite important; it ensures that the brew head and the filter got the right temperture, when I brew the coffee.

The machine heat the water to 93 deg. C, which is the right temperture for brewing, butfilter wont keep this temperture, when not used for a while. Therefore the temperture will fall by its way through the filter, which makes the coffee less creamy and more bitter.

So the procedure is:

  1. Empty the filter
  2. Attach the filter in the brew head
  3. Push the upper butter button
  4. Grind the coffee beens
  5. Let the machine pump water, and the big orange lamp turns on.
  6. Turn off the pump, when the lamp has been turned on for ~3 seconds.
  7. Detach the filter immediately and dry it with a tissue.
  8. Fill in and tamp the coffee, when the filter is still hot.
  9. Attach the filter and brew the coffee quite after the lamp is turned off.
Perhaps you will notice, that the coffee comes out much more creamy than it used to, whithout this procedure.

- And you never have to clean the screen and the filter ;-)

Enjoy!

Hi
More than likely its you brew head screen. Coffee will build up on the top surface and turn rancid after awhile. Remove the screen(its either a screw or bolt that holds it on). I like to remove everything and turn the machine upside down on a towel. That way I can see what I am doing. Clean everything even around the brew head gasket. This gasket needs to changed every year for best sealing of the portafilter. Buy 2 because they always fail on Friday when you have a party on Saturday.
Soak you brew head screen in hot water with a pinch of automatic dish washing detergent or espresso machine cleaner. Use a tooth brush to remove the crusty burnt on coffee residue or just buy a new screen. Clean this screen every 6 months because they should last the life of the machine.

SOURCE: water will not come through the steam wand

I had the same problem. I took the steam wand off, and checked for steam out of the unit. It was OK, so I stuck a thin wire up through the steam wand and dislodged what look like pieces of a green washer or O-ring.
In short...the wand was plugged.

SOURCE: leaking steam valve rancilio miss audrey

you should take out the knob first, than you try to disasembke the SHAFT of valve from the valve body, in this types(small espresso coffe machines) usualy producer use conical valve, without seals she close metal to metal, when you get out the SHAFT you will see one line on the conical end. for repairing it will be enough to visit one metal vorkery where they will take a small amount of brass from end and polish it. then you put it back and work again with your machine.

ps: notice you only polish the SHAFT , dont let them to short the more than 0.5 mm

My Rancilio Silvia, about three years old, does not seem to be generating sufficient pressure. Standard espresso grind requires about two minutes for a shot and coffee is bitter. Is there any way to...


First things first, remove the screw and shower in the head and clean. Then change grind to something a little coarser, since we are testing the machine we will not tamp the coffee(we are doing this to have a constant in our coffee brewing equation). Note how long it took to brew, if it brewed longer than 40 secs, then adjust grind and try again. If coffee shots looks better and taste better then we are on the right track, we are looking for any thing between 15 and 30 sec depending on the coffee blend from light to dark. If you are getting the same results over 40 secs for a shot no matter what grind you use then the pump needs to be replaced.
