    • When there is water leakage from the steam valve, there are 2 sources, external and internal. External leaks are a matter of replacing bushings and shown eslewhere. This guide shows how to deal with internal leakage. First, descale the machine with a commercial product, like Dezcal. Unplug the machine from the power source then follow the steps:

    • Remove the six screws holding down the cover. Note that the top screws have fine threads, while the four lower screws have coarse threads. Keep this in mind for later reassembly. Once the screws are off, remove the cover.

    • Note where the steam valve knob connects to the valve assemble, at the top is a small hex nut. Use the 2mm hex wrench to loosen the nut by turning it counter clockwise, about 1/4 turn. Hold on to the wrench, keeping the steam knob shaft in the upright position.

    • Now, while bracing the hex wrench, turn the steam valve knob slightly in a clockwise direction, perhaps 1/8th of a turn or less. This is compressing the seat of the steam valve plunger to close off the water leak when the machine is on.

    • Replace the cover, making sure the steel lip at the front is in its slot, and that the black plastic bushing is in place at the back of the cover. Replace two of the six screws, to save time in case you have to repeat the process.

    Thank-you for this info, just fixed the leaky steam wand and now works perfectly. Happy Camper.

    • Load and pour an espresso shot, and check the steam wand for leaks. If the wand is still leaking, go through the steps a second time.

    • If the steam wand is still leaking after a second try, then the steam valve plunger needs to be replaced. This is part number 8 on the schematic. Overhaul kits can be acquired from sources like espressocare.com. You can follow the tear down instructions on this site, or some of the video sources on youtube.com.

    I can’t believe how easy this fix is and sorry I didn’t research this long ago! I have had my Starbuck’s Barista for over 20 years. The wand has leaked likely for the last 10 years but I would use a wrench to help close it while I made expresso or hold button down knob to minimize leaks. I followed the steps and within minutes, now have a leak free wand and a perfect expresso. Thank you for this. I was going to replace my Barista machine thinking it must be a valve or some major fix but all I needed was to follow these simple steps using a 2mm Allen wrench! Thank you for these excellent visual, step by step instructions. So easy and I can keep using this well built expresso machine.

A well thought out repair. However, the internal part that needs to be replaced is actually part number 9, which is the actual gasket for the steam valve plunger. I’ve done this on my old Saeco Barista and it worked well. My machine is 16 years old and the boiler works like a furnace. These are excellent machines.

From where did you buy the part, please?

I get my parts from Ebay, the seller is called coffeesection , parts ship from Bulgaria. He has everything you would need, his shipping prices seem high but he will provide free shipping if you do not demand tracked shipping.
