Vibiemme Domobar steam valve dripping...

Postby milarsky on Sun Sep 12, 2010 10:23 am

Hello All,

I have a 8 month old Vibiemme Domobar Manual which I just love. Recently there has been a few small drips coming from the area just in back of the steam wand knob while steaming cappas. Is this a gasket or something that I can replace myself?

all best,
Jeff

Here's the kit you need:
Also I recommend that you get:
- a small tube of Dow 111
- and might as well pick up a couple of spare portafilter gaskets (the Domobar Super machines take the 8.5mm)
- and the replacement shower screen he carries are of MUCH better quality than the originals. It's far easier to remove without denting or bending.

A spare vacuum breaker is also part of my standard spare parts kit.

Both my Domobars came with the screen indicated.

Thanks Randy!

Now, could you quickly describe how to install those gaskets. I am pretty handy with the wrench...

Machine OFF and COLD !!

Open the valve as far as it will go. Loosen the large nut behind the valve knob and back the valve out more to remove.
It's a good idea to put some masking tape on the nut or use a thin cloth to prevent marring the gorgeous chrome.

The seal in the end of the valve just pops out.
Replace the o-rings 1 for 1. Lube them before installing.

Reassemble and snug down the nut.

From memory, it is quite easy. Machine off and cool- open the valve about half way. Hold the body with an adjustable wrench, protecting the body with a folded rag. Loosen the large nut at the end of the valve (right behind the handle. Continue to unscrew the nut and open the valve as you go until the nut is off the threads and the valve's operating shaft comes out. After that it is all quite self-explanatory. If you need more I can do a set of photos and a repair lesson on my website. Just let me know.
