I had an issue yesterday on my Vetrano 2B . . . the machine had warmed up for an hour already and I was just starting to make my espresso.  As I was pulling a shot the water stopped pouring!  I realized then that I was out of water!  Oops . . . . however, the machine and lights were still on!  I thought the machine turned itself off as a safety precaution when this happened?  So I turned both switches off, refilled the reservoir, turned both switches back on, and the pump kicked in to fill the boilers and I was good to go!  I am using bottled water and wondering if maybe there are not enough electrolytes in it to trigger the shut-off sensor??  Also, shouldn't the machine have turned itself off automatically?  If the machine does not turn off when it runs out of water, that could be a serious issue if it happened when a person is not home??  Normally I am pretty vigilant to check the water level every few days but it happened.  Nevertheless, I just want to clarify the safety aspect of the Vetrano 2B machine for other owners.

Possibly the tank was low, but not empty and possibly you had the pickup tube positioned so that it was not near the bottom of the tank.

You do need to watch the water level. I haven't had it happen to me, but I suspect that the machine will cut off in mid shot of the tank safety switch detects that the tank is low while your pulling your shot.

I thought I read somewhere that it would turn the heating element off but allow the shot to finish so as not to power off during pulling a shot.

I followed this post initially (for about the first 120 or so pages LOL), but tailed off in the last couple of months... I flipped through the prior pages (painfully) to try and find out if there was ever a root cause determined on the GRRR noise the V2B was making when in reservoir mode??  Was there a response for QM on how to resolve, or at least a root cause identified?

I am still toiling on whether I want a V2B, Mini Vivaldi, etc and I actually delayed my purchase by *months* due to the introduction of the V2B, I know QM makes top notch products and wanted to give it consideration. The QM67 did not bowl me over (and probably why the V2B came out soon after).

Thanks in advance!

Mine wont.. I have had to shut off in mid shot before.  The only solution is to make sure you don't let the tank get too low.

DeanOK, you read above that the same happened to me.  So how is the safety shut-off switch working if it doesn't kill the power when you run low on water?  Something is wrong here??  Perhaps another user can chime in with some more info . . . perhaps Chris himself?

The tank sensor shuts the entire machine down, including the pump, when the tank gets low... if your in the middle of a shot when the tank sensor senses a low water level, it will shut off in the middle of your shot. The solution is to keep water in your tank and not let it get that low. I don't really think Chris can add much to that... it is what it is.

You failed to read my original post . . . the machine failed to shut off when it ran out of water!!  The shot stopped half way through but all the lights were still on.  Therefore, it was still heating the boilers but with no water available!  That is my point . . . running out of water was not planned but can happen to anyone/anytime.  So I am asking those in the know, is the tank sensor faulty or what??

Not necessarily true. I have encountered a situation where the lights were on but the heaters were not: when you change values on the PID.

How do I know? I started it up the other day, then decided to try and increase my water temp by 1F because I had a new bean which I thought extracted better at 203F. I walked away for half an hour and when I came back the machine was still cold. The lights were on, but yep, you guessed it, I forgot to get out of the PID menu. So while the machine is on, and all the lights are on, the boilers can be off.

So I'm not saying with certainty that when the machine low-water sensor is triggered that it does shut off the boiler, but it's a possibility because the machine can be on without the boilers being on, under the right circumstances.

So who wants to go test this out? Quite frankly it's a non issue for me so I'm not going to bother. I'm not worried because even though the pump/motor is stopped by low water, there's still water in the boiler (it's just the reservoir that is low, not the boiler) so in theory there should be no harm to the heater being on because the boiler should still be filled with water.
