![]() ![]() If this doesn't work you may need to replace the mushroom valve and spring. If it still leaks after reassembling you can then try to stretch the spring a tiny bit to increase pressure on the mushroom valve but don't over do it. Check the mushroom valve isn't damaged before replacing. When these are removed, flush some water through by pressing the brew button. Once it comes loose take care not to lose the spring (No. If you use the wrong size screwdriver you can damage this part so be careful, it should fit snugly. 45), which the Shower Screen screw came out of. ![]() Then use a fairly thick tip flat blade screw driver to unscrew the mushroom valve holder (No. Saeco Espresso Machines, Parts for Saeco and Starbucks espresso machine There are also photos of the parts further down the page. The link below has a parts diagram for a Starbucks Barista which is a rebadged Saeco Via Venezia for the USA market. If it is excessive you can try to remove and clean the area around the mushroom valve which sits above the shower screen screw. The group head leaks without the PF in place and when in place and you switch to steam it leaks through the PF (not where it attaches - keeps dripping through the two holes underneath).The Saeco Via Venezia does leak a little water from the group head as it heats up to steam temp as mentioned by others. Reubster - this machine doesnt have a 3 way valve. Not sure about the leaking from GH, will obviously be something not sealing inside somewhere. (No connection to me, just a happy customer, non forum sponsor so details not posted.) If this doesnt work, the o rings inside may be buggered & need replacing.įound Saeco to be hopeless to deal with for parts supply, PM me for contact details of a country Vic supplier of parts and repair advice for the VV I have had good mail order service from before. This enables the knob to rotate the shaft an eighth of a turn further into the seat inside, which should make it seal properly. You need to undo this grub screw a turn or so, rotate the knob anti clockwise an eighth of a turn on the shaft, then nip up the grub screw snug (dont try to overtighten, not needed). Refer pic attached from Starbucks Barista, item is marked "B" in pic. Youll see a small allen headed screw (aka grub screw) that holds the knob onto the shaft (might need to rotate the knob anti clockwise to see it). You do this by unplugging the machine, removing the two screws on top to release the top cover, and having a look at the front left of the machine where the steam knob is connected. The knob only rotates the shaft into the machine so far, you need to adjust the knob on the shaft so it closes a bit further. I have a VV too, & fixed the leaking steam wand before by adjusting how far the knob closes. Do you confirm that? My goal is to pinpoint the problem and if the thermostat is Go, then I can dig for something else.Re: Saeco Via Venezia Espresso leaking. I also thought a thermostat is either Go or NoGo, that it could not be partially defective, as if it would command to stop boiling at a lower temperature point than designed. Like what is the trigger for the steam thermostat to stop boiling the water? Can it be as simple as let’s say 120DegC (250 DegF)? But I’m not sure I understand what the thermostat input is and what output it gives to the boiler. Somehow I feel the water may not being all turned into steam (or less than it should be). My understanding is that when I press the steam switch, the boiler starts heating the water to transform it into steam. I then open the valve and eject a bit of water for 2 seconds before I start to steam my milk (with only a 60-70% efficiency which is my problem). I confirm that the steam light comes on approximately 1-2 minutes after the steam switch is pressed, which is as it always been since day one. This can also cause less than optimal heating. If there is, you have current leakage due to corrosion inside. Unplug the machine, and place one lead of a multimeter on the top of the heating element, and the other on the metal of the boiler. This can happen if there is corrosion inside the boiler that wears through the coating on the element. You can also check the heating element for current leakage. There are two, and it sounds like if the machine brews coffee normally, it might be the steam thermostat. The thermostat in your machine is probably simply failing. Some of the newer models have a reset button on top, but those either work, or don’t. When the upper limit is reached, the circuit “opens”, and the heating element stops heating the water. Your understanding of the thermostats is correct, they usually work, or don’t. It sounds like your thermostat is functioning to a certain point, if the light is coming on. ![]()
