My pressure gauge has stopped working. The machine seems to be working the same. Is there an easy fix?

Very likely the pipette from the multifunction valve to the gauge has clogged with a bit of calcium.  The tube is very narrow but you can separate it from the multivalve (Right there on the body of the pressostat on top of the boiler) and poke it clean with a long thin length of baling wire.  While doing this, it couldn't hurt to take the whole multi valve off of the boiler, separate it from the pressostat and descale the breather-valve side of the multi.
If you have access to a compressor, you can blast the end of the gauge's pipette with air and see if the needle moves to test whether you've cleaned the blockage or not. Alternatively, if the gauge isn't cleanable/repairable, now that you've got it out, you see how easy it is to replace should you order a new one.

Quick question Cuadra owners.

What does your boiler pressure drop to when steaming?  Just curious as mine seems to go fairly low rather quickly.  Pretty much as soon as I open the valve a turn, it drops to .7-.8 BAR.   Seems to be a little low, no?

LOL. You are determined to have a problem with your boiler.  You may be a cofeecondriach. The pressure will drop while steaming.

It's the OCD in me.  :D

I only ask, because doing some research, I've found other machines such as the Giotto only drop maybe .1 or .2 BAR, where mine is dropping .6 or .7.  

Just curious to see if I have an issue or it's just a Cuadra thing.

My pressure drops quite a bit also.  After about 20 seconds of steaming 10 oz of milk in a 20 oz pitcher, the pressure drops to less than .5 and isn't really moving the milk very well and I'm not even close to 145 degrees yet.  I've been thinking about increasing the pressure.  I'm idling at 1.1 right now.

I will preface my response by saying I have just enough knowledge to be a danger to myself and others. I would think to make an apples-to-apples comparison of the different machines you first need to know:

1) boiler capacity
2) Pressure settings of each machine
3) The volume of steam/time by released by each machine
4) margin of error of the gauges

Having said that, yes, the pressure on the gauge drops off fairly quickly but I have no problem steaming enough milk on the cuadra for 2 milk drinks at a time.

If you boiler were over-filing as the the one fellow mentioned to someone a couple pages back, I could imagine that would reduce the volume of steam the boiler would have, but I do not know that for a fact.

Sly,

Here's a thread I found on HB of a Giotto user showing a similar drop off in pressure when steaming:

Click Here (www.home-barista.com)

The machine is all but identical to ours and he seemed to resolve his issue with a different steam tip.

There's also a few posts in this thread of machines with similar boilers/heating elements and their drops seem no where near as drastic.

Click Here (www.toomuchcoffee.com)

I noticed this morning when making my latte, the pressure dropped to around .5 BAR while steaming.   I had an ok swirl going but it definitely felt like it lost a bit of oomph.   Would it be possible for you to see how yours does when steaming next time?  Curious what kind of drop you're seeing.

Cruize,

I run my boiler a 1.2, so it's something you may want to try, especially if it's dropping that low while steaming.

I'll try to take note of it in the morning.  I am using a two hole tip.

My Pstat is turned down fairly low. The machine idles at .9 bar. When th element kicks on it goes up to about 1.05 bar.

When I started steaming milk for my latte, the boiler was at .9 bar. When I was finished it was at about .65 - .7 bar.

Obviously, the change is pressure will be effected by how far you open the valve and for how long, etc.

Hope that helps.
