I bought one and started to use it today. When the water starts to heat up, it makes a pretty loud humming noise until the light went off. Is this normal?

I have moved this post over to the right area...

Brand new Rancilio Silvia:

OK. Assuming you have read the manual.

I need more details.
Some questions:
a.) Have you primed the machine?
b.) Have you ever used this machine before?
c.) Have you ever used a pump driven espresso machine before?
d.) *Important* - how loud is the hum?
e.) How loud is the hum relative to the hum it makes
when you press the brew switch?

Assuming you are in New York City - who did you buy the machine from?
Assuming it is brand new...

Hi Colin:
thanks for the reply.
a) yes, I have primed the machine according to instruction
b) no, I have not used this machine before
c) no, have not
d) it's audible from 15 feet away
e) not applicable because the noise goes away once the main switch light is off - I assume the heating process is over
f) I bought this online, from BeverageFactory.com. It was not listed "used", I assume it's new. All other sites sell it for the same price.

OK - good answers.

Have you brewed a shot of espresso with it?

Does the "pump" sound normal to you.

I know that many espresso machines with boilers
make a very small amount of noise, including metal
expansion and a variety of thermal type noises.

The kind of hum that you are talking about (when the
boiler heater is working...) should be at a "whisper" level...
or a cat purring in the background. It should not drown out
anything going on in the kitchen.

Do you have an iPhone or something to record the sound for me?

Colin:
Somehow the hummer noise doesn't come back when I made used the machine tonight. I think it might have been the pressure built up in the steam wand that did it. I really appreciate your responses!
Are you familiar with this machine, V3? I have a feeling the online stored gave me a used one. The surface have some scrapes and scratches. Also, the group head seems hard to turn unless it's empty. Maybe I did not temper hard enough? How do I tell if it was used?
