Steam Wand Leaking on La Pavoni Espresso Si

No matter what I do, or which mode it's in, the steam wand has started to leak water constantly. More vivid when pulling a shot.

It is getting worse and no matter how tight I turn the steam knob off, it still leaks whether it is in coffee mode or steam mode.

What can I do?

I HAD the same problem. I fixed it for 50 cents. It takes the removal of 4 screws (2 phillips on top, 2 long standard on bottom by the group) to remove the top to access the steam wand valve. Once the the top (and the chrome bezel) is removed, then screw out the valve counterclockwise buy ALL THE WAY until it comes out. There are 2 O-rings on the stem of the valve that wear out, Cut these off with a sharp knife, go to your local hardware store, buy 2 new ones for 50 cents, install new O-rings, and reverse the disassembly procedure. Voila, no more leaky steam valve!

As long as original components are used ,or in anyway heat and pressure resistant components because by accidents the insurance not paid out by some great espressomakers there are lead seals on it because accurate pressure tolerances and approval by steam and Metrological Organization. a little machine its not a problem but the great machines La Cimballi La Pavoni are special made and the high prices has all to do with the manyufacturing on safety.

The easiest solution is to replace the steam valve, you can also get a new seat gasket for the steam valve.

System is not priming


This is normal after you leave the machine unused for a long time. The water dirt or scale or both make many parts to stuck like glue. The presure pump might be stuck if even if you here the noise of the vibration the outlet have been blocked. another part that can be stuck for the same reason is the water solenoid. Both can be fixed by remove them desasemble them and clean them with a wire brush. If you have a litle technician knowladge this is a very simple operation. Of course if you persist you might unsuck by trying the procedure you mention but it seems that now it is hard to be hapen.
Good Luck

Water leaking from steam wand when brewing shots


Try this from another post. It should help.

The steam wand began to seriously leak but a call to Starbucks Customer Service line and I was talked through how to adjust it so that the leaking stopped. It requires taking off the top/back panel of the machine (6 philips screws) then using a small allen key (1.5 mm I believe) to loosen and adjust a plastic oblong donut-shaped thing (a "cam" actually) on the shaft of the steam knob... no more drips.
The key to prevent dripping is to open the steam knob without putting pressure on it when it gets to the full-open stop position. Cranking it too hard when it comes to a stop in the full-open position will slowly move the cam out of position. Then the shaft doesn't fully seat inside the machine anymore and won't fully shut off the water to the steam wand. Then, no matter how hard you crank the knob in the shut-off position it will still drip. The purpose of the cam is to stop the knob from complete unscrewing and it also turns the pump on and off for the steam wand. The cam adjustment is very small but completely solves the dripping problem. Seeing inside the machine made me realize how easy it would be to repair problems as long as I can get the parts from Starbucks or perhaps Saeco.

Water will not come through the steam wand


I had the same problem. I took the steam wand off, and checked for steam out of the unit. It was OK, so I stuck a thin wire up through the steam wand and dislodged what look like pieces of a green washer or O-ring.
In short...the wand was plugged.

Miela cv 615 water tank leaking and parts manual


Where were you trying to download the parts manual from?

You can open the front door and remove the panel but I would recommend getting a trained technician to do this. Having been through a big repair process on my CVA610, I can assure you that any money spent will be worth it by saving you a lot of hassle. These are complicated devices.

Pavoni, no steam from steam wand


i havent heard of this issue , it could posibly be the bent steam wand , but the nozle is made to be that way, because the pavoni eurpicola doesnt produce enough steam pressure , it enables you to create better froth
