Question about Rancilio Silvia Espresso Machine

1 Answer

Rancilio silvia 6 months old. never was out of water supply Problem Extremely noisy pump, that vibrates, expresso cups, sitting on the top of the machine while having a shot. I use only distilled water (1-2ppm minerals). Does it mean the pump is going bad, or is it normal wih this machine. I know my coffee grinder is not giving me fine enough ground coffee.

Re: rancilio silvia

Hey Folks. My Silvia was doing something similar to this after no less than 2 weeks of operation.

Not being too worried about the warranty for just opening the case and looking inside......I did so. Be careful. Unplug as you remove various panels. Just don't touch anything with wires. You can see your problem if it is the same that I had.

Remove water res. Remove SS top. To view the pump, I had to remove the SS shield separating the reservoir from the boiler area. You will find the pump attached to the bottom of the chassis. It is supported by a rather flimsy rubber mount. Mine was collapsed to one side.......and the pump was literally banging against the chassis. Yes.....that will rattle your cups sitting atop the machine. To prove that your pump is not held securely in its mount, actuate the ON switch and observe the pump. Use only short burst of power when viewing your pump as you are NOT pushing water thru the assembly....and of course, all those electrical shock hazards that exist.

If it is shaking side to side......that is your problem.

I took a piece of hot water pipe insulation that I had out in the garage and cut it to the length from pump fitting to exterior wall of cabinet. IU think that might have been about 4.25 inches (I fixed this problem over two months ago and can't remember the actual length). The insulation piece is very light and holds the pump quite securely in place precluding the side to side vibration and the terrible noise. The split in the insulation allowed for the water line to be held securely as it comes out of the pump.

Reinstall all shielding parts, etc.......and you should be back on your way to minimal pump noise espresso shot pulling!!

All the best........Arch in Virginia Beach

Loud drilling noise when coffee switch is turned on - rather than the usual purring noise - and no coffee delivery either

How old is your machine ? and what maintenance have you done over time such as replacing the shower curtain located at the pourring end of the hot water ? I had too very loud noise coming occasionnally from the stainless steel rack holding the cup while coffee is delivered. If your ground coffee is too fine it will stop flow during making a shot. Is water coming out when no coffee is placed in the portafilter.The water pump on this machine is a cheap pump that has to be replaced over time. Mine is 7 years old and has delivered four cups of expresso everyday of the year, and still working.3841c994-fb4b-459f-8d1f-710e0aafc3c0.jpg 2ead4f70-37c6-4236-a9c2-992dba149c4c.jpg

The pump switch is either burned out, shorted out, or there is a CPU problem. You will need somebody local to do basic electrical troubleshooting on this machine.

Rancillio Expresso Machine won't pump water through. Makes lound noise.

Hi There are a couple of things. 1. Your pump is not primed. Open the steam knob and push the middle switch. 2. Your intake hose is pinched or not connected to the pump, or your intake hose is not in the water tank.

The second one is your relief valve return water line. It just sets in the tank. Doesn't go anywhere.

Have a Rancilio silvia machine, grind coffee with a Rancilio rocky. Problem is that sometimes... more often than not, the coffee coming out of the portafiller spouts comes out quickly and sprays all over...

Try taking the portafilter out and run water through it as if you were making an espresso. check if the water coming out is very fast. I believe there is a screen there that is held in by a flat screw. If you take that off you should be able to see light through it. If you can't soak it in some cleaner until you can see light through it. There could be a couple of things causing this. The other thing that comes to mind is that the boiler has to much pressure but it should say on your gauge if that is happening. You might find that it just needs a good cleaning.

Loud noise

Your pump may have came off its mount and is now vibrating against something. Contact the person you bought the machine from.
