Proper way to backflush a Rancilio Silvia.

Rancilio does not recommend backflushing the Silvia. Sometimes we have to.
First remove the brew head screen. Clean the brew head screen and reinstall. The proper way to back flush is to use a blind basket. Place some Cafiza, or Joe Glow (espresso machine detergent, a level teaspoon) in the blind basket. Insert blind basket in the portafilter and insert the portafilter in the brew head. With the machine warm, turn on the brew switch for about 4 seconds. If the pump starts to get quieter, turn the pump off. Wait about 1 minute, and repeat.
Do this about 5 to 10 times until the 3 way valve runs clean. Rinse the basket and repeat about 5 times to rinse machine. Remove and brew some more through the brew head.
Never let the pump get quite when running the pump, while back flushing. This can damage the pump.

Rancilio Silvia - Water coming from behind into the drip tray when pouring a shot.


Correct
When you are finished and turn the pump off, the 3 way valve opens and relieves the pressure in the brew head so you don't get an explosion of coffee when you remove the portafilter.

When running the machine for a shot of espresso I get water leaking into it. It's a Rancilio Silvia, this occurs with every shot. All I've done is clean the machine.


Time for a new group head gasket and probably all the recommended preventative maintenance.

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
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.
