Several days ago, I posted about a problem I was having with my Silvia, and as I suspected, it turned out to be the pump. I wasn't able to find concise instructions on how to remove the pump; only general guidelines and no pics, and even though it wasn't too difficult, I kind of stumbled through it. I was able to rebuild the pump with some helpful instructions regarding a Starbucks Barista, but even that was a little different than my experience.

All in all, I was successful, but I was thinking it might be handy to have a concise, step by step tutorial of sorts, with pics, of how to replace or repair the pump, specifically on a Rancilio Silvia, if enough people were interested. If there already is one, please forgive me for my ignorance -- I searched and searched. For that reason, I wouldn't mind putting one together if the coffeegeek community felt that this was a worthy project. So, if anyone is interested, please reply here, and if more than one or two people are interested, then I will try to put something together.

Cheers.

Definitely interested as the pump on my Silvia is faulty, and from what I've seen online it's easy enough to dismantle and clean it.

For me it would be helpful to know what pre-requisites are involved, e.g. how to drain the water from the Silvia, and also how to repair the OPV as well.

So a big +1 from me.

Silvia is a simple girl, she only asks for a little love and attention and she stays happy.
Remove the cup warmer and water tank and nearly everything you need to get at for disassembly is open to you. A few screws and the case back is off, allowing you to access everything you need to see for the pump. A couple more screws and the front cover comes off after you remove the steam knob.

You might want to look at my rebuild thread for a peak inside, I did not do a step by step but once you see inside, you should not be quite so apprehensive about it.

There isn't much on disassembly but I do take a lot of pics going back together.

Even though it is pretty straightforward, I know from my own experience that it's always nice when someone spells out the nuances/details of something like this. Problem is, my wife's due to have a baby in the next two weeks, so I'm not sure if/when I'll be able to get to it in the near future. I'll try to post something soon, but can't make any guarantees at this point! :-(

I'd initially just like to find out how to drain the Silvia of water, which I assume is necessary before removing the pump, or am I mistaken on this?

I'm pretty sure it's safe to take the tubes out of the water (being careful of course not to mix electricity with water), turn the machine on, and run the pump for about 10 seconds until you hear the noise change to more of a chattering noise. At least that's what I did, with no ill effects. I'm not a technician, so if it damages anything, please don't blame me!

Yes, remove the tubes from the water tank and remove the water tank from the machine, you should do this from time to time to wash it anyway.

On the other hand, there is no problem with water in the boiler when removing the pump, you might get a dribble from the disconnected tube but if you are ready for it, you should have no issues, just keep a towel handy to mop up the few oz of water that leaks out.

Yep, if you have any reservations about running the pump dry, like calblacksmith says, it's not like a ton of water is going to come out anyway.

I just replaced my pump and took a moment to write up a replacement guide. Hope it helps someone out.

Thanks for posting Aerotec. That would've made my life a little easier a couple of months ago! I would simply add that someone may want to try rebuilding before replacing. I found instructions on how to rebuild an Ulka on a Starbucks Barista, which I then applied to the Ulka on my Silvia, and it was really quite simple. I soaked the parts in vinegar for a couple of hours, and behold, the pump was like new again. That, coupled with your instructions on replacement, and everyone should be good to go.
