I thought my repair job was over... But since a few days ago, the steam wand is leaking again. Curiously, there's only a tiny bit of condensation at the tip after the machine is switched on, with no leak of steam -- the wand is cold to the touch. After my first cappuccino, I can hear and feel the st...

I'm happy to report that the parts supplier helped me unscrew the stubborn parts, I replaced all the gaskets / seal and now my steam wand is not leaking steam! Now that the steam wand is no longer leaking, I've found that the hot water faucet is slowly dripping. It's far less annoying than the steam...

There is no leak visible on the faucet mechanism proper; the only symptom of the leak is at the tip of the steam wand, where I can see / feel steam escaping even with the steam knob fully closed. So my guess is that it's a different kind of leak from the one you had at the ball joint. It's good just...

Here's a photo of my partially disassembled steam valve, with notes. https://imgur.com/a/qieCgvy

Is the leak caused by the absence of the pair of 219s? These appear to be the only gaskets I can get to without disassembling 218 and 228.

The good news is that the parts you can't get apart are in the hot water assembly. Only the parts in the top assembly are for the steam wand. Hi Chas! Thanks for your response, and apologies for the time it took to report back :-P I just checked the machine again, and it appears the hot water fauce...

Wow, it turns out I was unable to get to work on this task for no less than 5 years. My previous repair schedule turned out to be too ambitious... :-| I started disassembly last week on the back of a recent move, and while I managed to take off the knob and remove the valve from the front panel, I'm...

Hi Chas, sorry for the late reply.

I've been trying to find specs for the washers you mentioned, so I can get exact replacements prior to disassembly, but didn't get far.

I'm planning to perform the disassembly this week; will keep you posted.

Chas, thanks for the confirmation.

Is there a way to determine which of the 3 washers need replacing, or should I replace all 3?

Are there any disassembly instructions?

I came across this thread while searching for any hints on a new problem with the steam wand on my Vivaldi 2 (purchased 2007). The steam wand is leaking steam, even when the steam knob is fully closed. As it does, it makes a hissing sound, heats up the wand, and eventually causes a small puddle of w...

Reporting back: there was no sign of damage on the triac for the steam boiler when I took it out. Since it proved to be difficult to obtain a replacement triac here in Switzerland, I took a gamble and asked a friend who has an electronics hobby if he could try to find and replace the faulty part. My...

I'm getting a quote of ~$80 shipping for the part from Chris Coffee. Aside from the monetary expense, this will get me past the customs allowance and trigger quite a bit of hassle and additional expenses to bring it over here. And the irony is that next week I'll be in Italy for vacation, not too fa...

chas, thanks for that tip. I've disconnected the cable just above the cable that goes to the fan (marked 'P1' in the triac connection diagram in the manual http://s1cafe.com/s1v2/V2%20Manuals/V2Owner'sManualRevH.pdf) and confirmed the steam boiler heats up. So I guess that settles it... it seems to ...

BTW: In order to minimize the current draw in 20A mode, the group boiler heats up before the steam boiler even turns on. That way you don't have a 10-15 minute period where both boilers are drawing current constantly. Therefore, the unit is normally on for 10-15 minutes before the controller board ...

Hi, On the latest turn in my attempt to fix my steam boiler (first documented here: http://s1cafe.com/viewtopic.php?f=57&t=2261) I have managed to replace the heating element with a trickily obtained replacement part (110v), put the lid back on, put all the wires back in place and... now the ste...

Thanks for the advice. That plug really was holding the boiler to the chassis, at least for my machine, but luckily I was able to convince it to unscrew. I did end up choosing not to remove the boiler after unlocking the drain plug, as it was enough to remove the debris that had by now dissolved in ...

Hi, I'm a relatively happy owner of the S1V2, purchased in Canada in 2008. Recently my steam boiler heating element blew -- scale built up at the tip of water level sensor, causing the boiler to overflow and shorted the heating element -- and triggered my saga of getting the machine back in order. I...
