The S1 Cafe - Helping Your Espresso Dreams Become Reality

Just to add some more info to this, I've set my schurflo accumulator to 20 psi, my flojet is set to 40 psi which is 2.7 bar however after a couple of shots when the flojet pump cycles, the pressure gauge on my S1 goes up to nearly 4 bars. I'm left scratching my head with this, I'm thinking S1's pump...

Hi all, I'm having this issue with my S1 that is puzzling me and hopefully someone can input some helpful advice. The preinfusion seems to have a little pressure at the start, during the first couple of seconds after the solenoid valve clicks, the preinfusion water gushes out with more pressure then...

I think chas is right here, I had a similar issue trying to fix the steam boiler in my s1, I took my machine to atleast 3 different coffee machine repair centres and all of them told me that I needed a new motherboard without first testing and diagnosing other faults that could cause my steam boiler...

Hey chas, hope you're well and had a great Christmas. Just wondering if you're up and running again with your two recently faulty machines and any new difference you've noticed coming back to the dream from the la marzocco if you've had a chance to use the dream.

I'm surprised that is hasn't got alot more interest from Vivaldi owners as it's a very handy little part. I recently descaled my steam boiler which I think is a must for every Vivaldi owner's maintenance program as the amount of limescale I found inside was scary stuff. I had to srape the existing g...

If you're in the UK then one of these will solve your problems for ever!; http://m.ebay.co.uk/itm/La-Marzocco-GS3 ... nav=SEARCH

I'm finally set up now! It has been a deep learning curve fixing this machine but defidently not possible without the help from this forum and it's very helpful members. I'm impressed allready with the level of crema and it is only my first week. The amount of steam available is scary stuff, nearly ...

Just to answer my question for the interest of the forum, The rotoflow pumo used in the S1 is called CA054 Compact. The PDF document relating to the compact rotoflow specs is: http://www.chichesterpumps.co.uk/media/wysiwyg/COMPACT-COMPACT_PLUS_0611_Ed.pdf Reading the flowrate from the chart I think ...

I too think that my steam boiler is taking too long to refill, I tried to get to the gicleur valve but I think my machine (2011) has one of the newer gicleur valve assemblies fitted as the gicleur valve does not come. I have looked at the steam boiler 90 degree bend connection and have taken the wat...

I managed to fit the new ssr on the inside of the machine which was a bit of a tight fit but at least it has fixed the issue and the boilers are operating normally now. As usual with this machine, onto wrestling with the next fix :evil: The steam boiler takes too long to fill resulting in the machin...

Thank you for your input again Chas, I really don't know why you you're not running for president, you'd certainly get my vote! I would've gladly handed over the machine to a qualified technician to save myself all this trouble however I took the machine to two la spaziale approved coffee machine re...

For the interest of the forum the brand and model number for the SSR is CARLO GAVAZZI RA2A23D25

I tried to go over all the connections to make sure the wires were plugged in tight and not hanging out anywhere and plugged the machine back in and the same thing happens as before where as on standby the steam boiler heats up straight away. I feared from reading the other forums on the s1 site tha...

Hi Chas,

I didn't disconnect the control wires to the triac or anything else for that matter whilst I removed the control board, maybe I disconnected a wire accidentally whilst I pulled out the control board so I'll check it again later and report.

Okay, I found out what was causing the steam boiler to overfill and thus blow the pressure relief valve, The wire for the boiler refill had snapped off whilst descaling so I crimped it with the a female spade connector that was too loose and wasn’t making proper contact with the boiler refill connec...

Yes we have our 3 pronged plugs fused over here which turned out to be a good thing for me in this occasion. I was looking in the wrong place for the master 20A fuse inside the vivaldi like you mentioned chas. Any ideas on why the pressure valve went? I'm thinking that the overfill solenoid valve ma...

Thanks guys for your time and input. As usual with this machine I went about this the long way round as I thought I didn't have a master 20A fuse so I took the black board out to inspect the 5A fuse there, Chas was right that it was a bit of a pain to get the board out. I inspected the 5A fuse and i...

Hi Chas,

Thanks for the quick reply.

I looked under the machine where the power cable is and there doesn't seem to be any fuses located in this area, as you can see from my pics there is a an empty hole next to the power cord which I imagine is where the fuse should be.

I need help once again before I turn my back on this machine once and for all! I bought a used vivaldi 2 from a closing down restaurant and I thought I’d give the machine a descale after reading the detailed instructions here which I did however every step of the way has been a hassle to say the lea...

Many thanks again chas, you're a gentleman.

Thanks for the advice guys, there is an historic thread titled Steam Knob Slop Solution which is quite detailed and has clear step by step instructions along with pictures however the pictures does not seem to be loading up any more for some reason. The steam assembly blow out pictures in the manual...

I was wondering if anybody knows or has any instuctions on how to dissamble and clean the steam valve assembly. I recently bought a used vivaldi 2 from a closing restaurant and the machine was badly scaled and blocked and as a result as there was no water or steam coming out of the machine. The rest...

A quick update, I turned the machine on earlier just to play around with turning the steam boiler on and off and after about 20 minutes with the machine turned on I got a fault code; The lights 19-20-21 turned on which indicated in the manual that there is a steam boiler temperature detection system...

Hi Chas, Many thanks for the thermal epoxy advice, that will save me alot of running around. I did wait for the group boiler to heat up first and waited about 5 mins after the group boiler set temperature had been reached and turned the machine off and steam boiler was completely cold whereas before...

I recently purchased a used Vivaldi 11 from a closing restaurant who had removed the steam wand as they only wanted to serve espresso with the option of steaming milk taken off. When I finally set the machine up at home with my flojet pump I noticed that there was no steam being produced when I open...
