OR113 O-ring for Steam inside Steam and Hot Water Valve – Domobar Super/Junior The below instructions are a courtesy of 1st-line Equipment, LLC specifically for the VBM Super and Junior espresso machines. and to be used at your own risk. 1st-line Equipment, LLC assumes no risk or liability, and you hold 1st-line Equipment, LLC harmless, for all damages or personal injury arising from the use of these instructions. By reading further, you agree to these terms and conditions. If you do not, please stop here.

If your valve is leaking through the stem where the knob is attached to, you need to order two for each valve you are replacing these O-rings. To repair, unplug machine, allow to cool down, remove all steam from boiler by opening steam valve to full open position (even if repairing only the hot water valve). If repairing the hot water valve, turn to full open position once the steam stops exiting the steam valve.

Remove the wraparound body (usually 6 screws). On the inside of the machine, there is a nut holding the valve in place – not the nut on the tube, but the nut on the inner wall. This nut needs to be held with a wrench. On the outside, there is a nut right behind the steam valve. Place a terry cloth over the nut before placing a wrench to turn this loose. Once loosened, the steam valve stem can be further turned to open and come out of the valve. Replace two O-rings, lubricate with PetrolGel, and reverse procedure for installing.

      The hot water tap of my Domobar Super Semi-auto Gen 1 is leaking. I removed the valve, but it does not appear to resemble the technical diagram. The two o-rings (4 - GUAROR113) are not on the right, inside of the valve (3), but left of the threads, under the nut (2). What do you recommend?
