I was frustrated with the pannarello steam wand on the Delonghi EC702. So I decided to swap it with the Rancilio Silvia wand and thought I would share this for people thinking of doing the same. This would also work for the Delonghi EC701, EC710 and EC730 espresso machines. For upgrading the Delonghi EC-155 see the instructions over at KennethBallard.com
I bought the Rancilio Silvia 1v/2v wand over the V3 wand because it was smaller in diameter. I initially planed to drill a hole and pipe it to the boiler but the wand was about the same size in diameter (6.00mm) as the original. It was much easier to just swap it out rather then drilling and pipping it to the boiler. The only modification I had to do was widen the hole on the plastic wand guide holder. I did this with a hot screwdriver to fit the new wand through. Other than that it was a straight swap with Delonghi wand. It does hang over the side about a 1/2″ more and nowhere near the drip tray.
- Update 11/2017! The Rancilio v1/v2 wand (old version) is being phased out.
Difficulty Scale: 3 out 10 — Time: 45 mins Cost: $32.00
A clamp for a 6mm I.D. / 8mm O.D. hose:
Size 3 Worm Gear Clamp. — Not great but works,
7mm Spring clamp — untested
7-8.7mm PEX Cinch clamp / Oetiker ear clamp. — *Best, OEM Style.
*If you use an Oetiker or PEX ear clamp you will need a Side Jaw Pincer or PEX Cinch tool.
T-20 Security-Torx Screwdriver
Small flat head screwdriver — for the clips
Big flat head screwdriver or 9/32 drill bit ? — Something to widen the hole.
Remove the top.
Two screws in the back and 3 security-torx heads on the bottom cover. Lift it straight up.
Remove the bottom cover.
2 Phillips screws and 2 clips. Insert a small screwdriver to release the clips. Be careful when removing or you will snap them off, like I did.
Remove the wand guide.
Undo the screw in the back first. This screw has a nut, the nut is on the bottom under the steel plate. It’ll drop down when unscrewing. Put your hand under there and grab it. The other screw just holds the the top closed.
Now you can cut the hose, cut it close as possible to the wand or pry the old clamp off.
After removal of the wand guide.
The next problem is the new wand has that nub at the end and it will not fit through the hole on the plastic wand guide. What I did was heat up the tip of a screwdriver and just rounded it out a bit or you could drill it with a 9/32 drill bit?
I then fed the new wand in and attached the hose and clamp.
Hangs over the side a bit more.
I reassembled it but I left the top off to test it for leaks.
