Hey folks,

I've been using mine for a few weeks now, and I noticed today that the pressure in the boiler seems to be far from holding constant. It will go up to 1 bar, the pressurestat will kick off, and within about 20 seconds it will have fallen to .8 bar, when the pressurestat kicks back on again. It seems far too frequent, as if I have some sort of leak in the system somewhere. Any advice? I'll be researching myself, as well, but I'd love to pull from your Cuadra knowledge.

A little follow up from the last post. I didn't think that these were related, but maybe they are: I had noticed a strange gurgling noise as the machine heated up and it started to get more frequent. It wasn't an alarming sound by any means, but perhaps it's related to what I was experiencing with the pressure going down so quickly.

I thought the sound was coming from the group, which it wasn't. I had been pretty convinced it was coming out the exhaust of the e61, but after I posted I decided to get to the bottom of it. After I took out the plate below the drip tray, I was able to both visually and audibly confirm that it was coming from or related to a clear plastic tube under the tubing for the steam wand (see the attached image). Seems like every some-odd seconds, a bit of air is getting sucked through this hose. I'm not entirely sure what that hose is for (it's hard to see where it comes from and goes to), but I'll keep researching.

OR! Maybe I'm a hypochondriac. I'd love to hear more opinions, but having read this entire thread a couple of times, sly - I hold your advice in high regard!

Should be the vacuum breaker valve - and still sounds normal.

Don't go just by my $.02, I know just enough to be dangerous. My knowledge of the machines innards and how it operates are fairly limited, but I have been using the machine for a while and I am more or less familiar with its sounds and habits.

Every environment (ambient temp, draft, voltage, etc) will have a different result in how fast the pressure gauge goes down and how fast it comes back up.

Normal upon warm up.

Earlier we learned the owner of the company had passed on. Any news on changes to face the company? Also the name issue with E61
and Fameas request to not use it anymore. Any news there?

Posted May 19, 2013 link

Only new thing was a name change of the parent company. Still dealing with same folks at manufacturer.

ive had mine just over a month now. much more consistent results than with the lelit i had previously.  most shots have been exceptional. with all the flushing and  an occasional americano   i go through water pretty fast. been thinking of trying the large jar for water setup  shown below that someone posted. cant remember if i saw that here or elsewhere. ive  had  a little  trouble getting art worhty milk. tastes great tho. am very happy with my machine

Posted May 22, 2013 link

Warning! Warning! Warning!

(now that I have your attention)

More importantly, do not let that jar or hose run without water. And, do NOT put a machine with this set-up on a timer. If someone leaves the lever up or hot water valve open, all the water will be removed from the jar allowing the pump to burn out as well as damaging the boiler's heating element.

Less important.... on tank model machines, the pump is usually doing double duty (pulling and pushing water). Since the hose is being extended, there 'may' be a shortened lifespan on the pump. I am unable to answer by how much.

It is also a good idea that water be turned over every week.

Wait, no. Not normal!
He's saying that it's leaking over the breather after it has already fully warmed up.
You can confirm that it has a constant steam leak through that hose by pinching that hose to stop the flow momentarily. If the hiss stops for a second when you close off its path, you have confirmed that a constant leak exists over that valve.  You can disassemble the valve to clean the parts but will want to consider purchasing a new one. Having a back-up won't hurt and there will come a time when just cleaning the little teflon disk will no-longer stop the leak.  I'm sure 1st-Line will be happy to sell you one. If they continue to suggest that it's normal for it to leak constantly, it will be up to you to decide.
As you see, that assembly has multiple functions. It has a connection for your gauge, it sits on the stem for your pressostat and the side opposite that breather valve is a safety-pressure-relief valve. I suggest not disassembling that safety-relief.  If it doesn't leak, there's no need to disturb it.
Oh, and "By the way", the other end of that tiny hose just drips into the back corner of the drip tray down that channel on the front wall of the machine.
