Repair for Leaks Originating from Steam of Valves for Hot Water and Steam

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.

Repair for Connection between Wand and Nut on Steam and Hot Water Valves
This O-ring, on most VBM and other brand espresso machine where the steam wand connect to the valve’s bottom nut. Inside the nut, there is an O-Ring which prevents leaking between the nut and wand connection at the bottom or side of the valve. In must cases, there is an upper tightening nut which needs to be loosened upwards, then the lower nut is removed along with the wand. To get the wand removed, sometimes the steam tip needs to be removed so the wand can slide through the nut. The old O-ring should be removed. The new one needs to be lubricated with PetroGel, and then inserted into the groove for the O-ring at the inside bottom portion of the nut. Then the wand can be inserted, steam tip attached, and then place the assembly back onto the valve. Tighten to the point whereby wand has a low level stiff movement, and then holding the lower nut with a crescent wrench, bring the upper nut downwards.
