Unable to prime Sirena Espresso Machine

After repeated attempts I'm unable to prime my Starbucks Sirena Espresso Machine. I've followed the instructions in the manual to the letter with no avail. With water in the reservoir and the steam knob open at full no water is released via the steam wand. The magnet in the reservoir also moves freely.

Any assistance would greatly be appreciated :)

N regards of the no prime issue. this is the only way i could prime this new puppy.make sure its stone cold which is a no brainer since it will not heat h2o unless its primed. first take off steamer plastic tip ,turn on steamer clock wise till pump starts. then **** the tip of the end of the metal tip hard until pump stops may need to do it a couple of times. yes this seems out of this world but it works. you are flushing out the vapor lock in the pump. bravo enjoy!

    the word **** means to draw air out through your mouth inhaling hardv with your lips sealing the tube tip.

    I moved the metal want around in circles for about 10 seconds and it worked. No sucking :)

    I read this solution, and then read through the entire rest of the internet, seeking a different solution, rather than subjecting myself to the shame and degradation of the above steps. Unfortunately, nothing else worked. I timidly got down on my knees, and starting sucking on the tip of the steamer. Gently at first, but that didn't work. I started sucking, harder and harder, and suddenly, I felt a little bit of air coming through. Encouraged, i put the whole steamer in my mouth, and really commenced sucking and blowing, to try to get the air flowing. I felt a little bit of liquid flowing through and I increased the suction and the pace of the sucking and blowing. The espresso pump groaned as I alternated turning the primer knob on and off. Finally, the primer sent a glorious stream of water flowing into my mouth and despite gagging slightly, I choked/screamed in celebration. Simultaneous emotions of shame and victory coursed through my head. I had successfully primed my Sirena Espresso Machine.

What I had to do was to lift slightly upward on the water reservoir. *Very slightly*. When I did that, I was able to use the steam control and water actually came out, then the machine was primed and it started warming up on its own. The problem is that when I let go, the machine stopped working again. I had to use small rubber bands around the legs on the water tank to help it sit a tiny bit higher. I found that one small rubber band lifted it up high enough for it to work. Yay for great craftsmanship lol.

Sirena Espresso Machine powers on but will not heat up and water not priming

After weeks of trial and error, I have found the solution, to prime the Starbucks Sirena Saeco Espresso Machine (woohoo!!!!!!!!!! ). You do not need to disassemble this machine, it will not heat unless it is prim WARNING: machine must be STONE COLD before attempting this! 1. Get a large syringe (Without a needle of course, I used a 60ml one I bought at a pharmacy for $3.) 2. Fill the water tank full 3. Pull off chrome tip on the steam wand to expose the black plastic jet where steam comes out. 4. Place the tip of the syringe onto the tip of the black plastic steam jet on the machine. 5. Push the power button ON. 6. Turn the steam knob clockwise all the way until the pump starts. 7. Press the syringe onto the jet firmly to seal the connection, and simultaneously draw the plunger out. 8. Quickly, release the seal and eject the air in the syringe out (into open air not into the machine) 9. Repeat steps 7&8 until water draws into the syringe. 10. Go make yourself a cup of coffee and celebrate that you overcame the flaw in this machines design that renders most of them to the rubbish heap.

Will a Starbucks sirena portafilter fit on a Starbucks barista?

The Sirena portafilter is 58mm and the Barista portafilter is smaller at 53mm so the two are not interchangeable.

58mm is a fairly common size in portafilters however, so if you are looking for something different for your Sirena, there are options. Also the Sirena has a rubber disc and peg to function as a self-tamper, those can be removed so you can tamp your own grind and adjust it to your liking.

My sirena has blue blinking water light even though it has a full amount of water

Turn on the machine and turn the steam knob all the way on. Let it run until the light goes off. This primes the pump. It should run properly after that.

I have a Starbucks Sirena - the grounds overflow in the basket while pulling shots, and it drips forever after it's done. When I remove the basket it's a huge mess every time. All the parts seem to be...

it sounds like you need a new group head gasket, or the group head gasket is not installed properly.
If it is a new machine, you probably just need to reseat the group head gasket. If it is a used machine, the gasket is probably worn, they need replacement every 6-12 months.
The Starbucks Sirena is made by Saeco, and is also called the Saeco Sirena.
You can find the group head gasket (brew head gasket), and any other parts from the following:

Here are a few videos of the machine in use:

Starbucks Barista (Saeco) Espresso machine Quit pumping

Hi
If it makes a noise when you turn the brew switch on you may have a blockage in the out let line. If it doesn't make a noise but every so often you may have a bad pump.

Starbucks Sirena Espresso Machine no foam

If it is this new, and you have followed all the usage instructions, return it to point of purchase for replacement. With the Starbucks name, it could not have been cheap. Re-read all instructions and try again. If still no-go, return it.

Double shot won't work, single does

Try using without the portafilter, if it works then the problem is in the grind or the pressure used to tamp the coffee.
