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
