Subject: LaSpaziale S1 group head pressure problem
 

Using a dedicated portafilter pressure gauge, I find that the pressure to my group head is only 4 bars, and adjusting the adjustment screws per the section 7.3 of the S1 Owner's Manual has no effect on the pressure. Any thoughts?

Either:

  1. Pump has failed
  2. Pump bypass system (pressure adjustment) has failed, you could probably get part for this
  3. Expansion valve has failed or is letting by
  4. 3 way valve in group is faulty/jammed, failed in some way

All depends on what other symptoms you are getting.... you specifically mention portafilter pressure gauge and are careful not to mention the machines own pressure gauge reading, is this because it's the same or different. Also there may well be other things happening, observe and give more information if possible e.g. noises, water flows from unusual places, pressure ramp, flow rate etc.. etc...

Thanks for the response. You make good points. This unit has only one pressure gauge, and it appears to shows proper pressure, all within green, about .75 bars when fully steamed up but idle and 1.25 bars when I pull a shot into the portafilter with the pressure gauge attached. Turning on the steam arm produces lots of steam. Everything appears to be normal. Next step is to contact the company that sold it to me.

The section of the manual you refer to doesn't exist in the V2 online version I looked at, just to check what exactly you are fiddling with.

The pressure gauge reading for the steam boiler is irrelevant to this problem. The Vivaldi has a dual gauge and it's the brew pressure showing when you pull a shot into a blind filter that's of interest, because it might indicate whether there is a problem or not with the pressure testing portafilter you are using, or some other problem. I have actually known people use them with a basket installed!

Thanks. My S1 is a first generation that has only one gauge on the front panel for the steam, and I agree that it's not going to provide helpful information for my situation.

I talked with a technician at Chris' Coffee, and he gave me instructions for trouble shooting. He recommended that I disconnect the pump motor to see if it is turning or has seized up, etc.

Well it's obviously turning otherwise you would get no flow of water from the group and no pressure reading. The pump could be partially seized, but you would hear the motor labouring, the MK1 Vivaldis were very quiet machines so a labouring motor would be obvious, accompanied by the usual screeches and whine from a failed pump. Lots of water from the expansion valve would cause the problem, but if that's tight and not gushing water, then another area is to validate the reading from the pressure gauge...someone with an espresso machine nearby.

The lack of information from you to help diagnose the problem (which I don't believe is intentional), leads me to think that technically you may not be best placed to solve this problem and should perhaps send it off to be checked/repaired.

I've got to purchase a 90 degree screw driver that can fit into a tight space to detach the pump from the motor per the technician's instructions. At that point we should be able to diagnose the problem.

Not true if the pump is not turning you will still show pressure in his gauge but it will be line pressure only. The solenoid will open and water will flow through the group.

Yes, forgot it's plumbed in (my bad) so it will show line pressure....always the problem when so little info is given by the OP, like water flow noises etc.., its why I advised him to send it to be repaired. So far the only real information given 4 bar pressure in a portafilter tester and normal steam pressure....no other information at all despite asking for it, so very difficult to help as I'm going to make assumptions like he can obviously hear the pump cutting in otherwise he would have mentioned it?.

If it were me I would have other ways to check whether the motor is likely to be turning and whether it's line pressure creating the 4 bar or pressure from the pump, or indeed if the pump motor is getting power, but the users skill/experience level and available equipment probably does not allow him to do that without disconnecting the pump

If your techs are on the phone with him, then they have a huge advantage in being able to ask him question after question and get answers.....hopefully you will solve it soon.
