Subject: DeLonghi Ec155 Wand Mod - HELP!
 

I upgraded the wand on my Delonghi EC15 to a Rancilio Silvia V1/2 wand (a fairly common upgrade for that machine), but the new wand isn't maintaining steam pressure, or really steam at all. I can't find any leaks inside the machine, and there's no water or condensation.

I made a short video of the problem: http://www.youtube.com/watch?v=_TyFCt1-2qI .

I know this isn't a common machine for enthusiasts, but I'm very much a beginner at this stuff and couldn't shell out $300+ for a super machine.

Anyone have any ideas?

Steaming is a function of how fast you heat the water and how much reserve space you have to store the steam (boiler size is important to both).

Manufacturers will tailor the parts of their machines to fit the design specs. When we mod them, we become the designer. I suspect that DeLonghi had a restricting device in their wand to allow pressure to build slightly to make up for the small size boiler/heater they use. I have never played with your machine to be honest but there is a reason that as you move up the price level of machines, they become more and more consistent and able to produce better espresso.

Axlsparks, welcome to CG.  

Watching the video makes me think that it is your bimetallic steam stat clicking on and off.  As you heat, good steam, and as it clicks off, the steam pressure falls.  As Wayne, Calblacksmith, noted you have a small boiler.  The largest variable in a given system is heat.  If that makes sense, the economical fix is DIY PID.  

Steam pressure vs temperature

Thanks to both of you.

I actually did some further testing and did discover a small leak (for whatever reason, steam didn't seem to be escaping and there wasn't any condensation inside the machine, but when I ran water through the hose, it was pretty obvious).

Used it repaired this morning and was working fine. Now I just need to learn how to use the new wand (and you know, actually steam milk well).

Thanks again for your help.

Congrats on finding your issue!
If you would like to practice a lot but don't want to drink gallons of milk, a drop of dish soap in water works well to help you practice without all the extra milk use!
