Subject: Rancilio Silvia V1 loose valve knob handle
 

Hi all

We bought our Silvia V1 2nd hand less than a year ago.
Recently the spring on the valve knob broke so we ordered another and fit it on the valve  handle
When we went to slide the handle back onto the valve it was loose and wouldn't turn the valve on or off.
It also trips out the electrics - maybe something to do with the valve handle not being on?

Is there anyone out there who has an idea what our problem might be and what we might need to do to fix it?

Thanks in advance!

Ben & Sharine

It's been about 2 years since I owned my v1s...but iirc, it's possibly to not put the spring on correctly, and in fact, "correct" seemed counter-intuitive.  So, first thing I'd check for the knob is that.  

I don't see any reason at all for the valve knob to cause your machine to short out, as it's essentially just a plastic blob that sits on the valve's brass shaft. There is something else going on.  I suggest opening her up and visually inspecting all of your contacts and wires, to see if you can find the damage that way.  Otherwise, you're going to have to get out a voltmeter and check every connection, switch and circuit that way.

Hi emradguy

Thanks for your reply. It is strange how it shorted out, only seemed to do that after we pulled the handle out.

With regards to the spring installation, it did seem a little loose. Would you mind trying to explain what is the correct was to put it on?

Thanks
Ben

I'd be happy to comment on a picture of the knob interface, spring and valve shaft, but it's been two years, so I can't do it from memory.  Any chance you can take a snapshot and post it here?

This machine needs to be unplugged and opened up for examination. The two events can only be related IF the valve itself is leaking inside the machine.

ok, so you put the spring on the knob shaft in the orientation you pictured and then slid that over the steam valve shaft, such that the valve shaft sits against the knobw under the spring...yeah?  like the valve shaft is encased by the spring on one side and the plastic knob end on the other? and that was loose?

Yes there is a fair bit of play and the handle doesn't go right the way back to the machine as it used to.
Also noted that the spring isn't tight to the handle as the other one was.
