Subject: Anyone had reliability issues with Izzo Alex Duetto II?
 

So, my Duetto is just over a year old.  Thus far:
1 -  the steam safety release valve failed at over 1.4 bars – reduced temp setting and it was fine, but technician advised to change it.
2 – The brew boiler thermistor failed, unit dead at that point.
Removing the thermistor was a b*tch, the entire boiler twisted slightly as I needed just about the maximum amount of torque I could apply to get the nut off.  I think this caused a small leak in the hot water valve fitting as there is now some corrosion at the fitting, yet I can’t see any leak now.  Chris’ Coffee tech said to just keep an eye, but no visible leak = no worry…but this has me worried as replacing that tube would be a very big job.

3 – now the PID push buttons stick closed if the unit is warmed up and the right button is pressed.  It had been getting "sticky" over the last few months.  It defaulted back to factory settings (both boilers 212) making unit unusable.  Fortunately, once it cooled down, it came “un-stuck” and I was able to reset.  But no more changing temps on the fly.

All of this happened right about at the one year point – worked perfectly till then.  I make 2-4 drinks/day.

Now, Chris’ has been excellent, sent replacement parts at no charge and talked me through the repairs.  I have not yet changed out the PID as that looks like it will take me some time.  I was able to do the others without a whole lot of trouble, although 1 & 2 took the better part of an afternoon (did them both at the same time, both happened within a couple of weeks of each other).

So, my question is, “is this normal”.  Given what I paid for this machine, I expected years of reliable function.

Yikes! Mine is almost 18 months old and I haven't seen any of these. Knock on wood.

Shortly after I got mine, there was a PID firmware problem that they fixed by sending out new PID controllers to existing owners. I don't remember the details of the operation, but with Jason's instructions it took me well under an hour (I think under half an hour) to replace the PID.

This is concerning. I really hope it's just a fluke. From everything I gathered, it seems the Duetto II is extremely reliable. I'm glad to hear that the folks at CC are helping you out.

I was watching a few youtube videos on the Duetto, and the one thing that struck me odd was the placement of the PID's buttons. If they were oriented vertically instead of horizontally, they'd likely be easier to reach without burning yourself on the group head. Not exactly on topic of what you're dealing with, but it was a thought, when I saw those tiny buttons and was wondering if they'd be prone to getting stuck or failing.

Best luck!

No kidding!  I've only had my Duetto II for a couple months now, although it was a demo model before I bought it.  I haven't run into any problems yet, but this is the first I've heard of anyone having ANY issues with the Duetto at all!  I was expecting to see a lot more Duetto owners chiming in here about their lack of problems by now.

 
...and on that note, I need a coffee.

I'll chime in here. I've had one of the early ones for 2 and a half years now and I've had no problems making a cupola dbls a day...

I have had mine 6 months 8 - 12 per day 0 issues. If the house burned down or something I would buy another one without a second thought.

 
Yes i have a reason for leaving SCG off my list, yes it is my opinion, yes it is subjective as opinions are by definition, no don't start a flame war because you disagree.

It's rare for any discussion forum to have people posting that everything is working fine.  By nature, the overwhelming majority will be people with problems that need help.

The OP is asking if anyone has had reliability issues. IMHO no's are as important as yes''es

I love my Duetto II!  I got mine mid-december last year.  I've have 3 issues...only one of which should be of real concern to anyone looking at this machine...

1) There was corrosion at the hot water pipe where it came to the valve on the machine front plate.  The guys at CCS saw that when I sent them a photo of the inside of my machine, so they could tell me if everything looked ok after about a years worth of use, and so they also sent me a free replacement pipe.  I installed it with little difficulty, which they helped walk me through. They said it was probably sloppy craftsmanship at the factory.

2) On Christmas day, this year, my machine shuddered and shut down during shot number 4 of the morning.  It literally scared the sh$t out of me, because I was thinking I would be SOL for at least a week, through diagnosis, parts and repair.  Fortunately, it was simply a matter of "the perfect storm" where the reservoir went dry while the boiler tried to refill, and the alarm didn't get a chance to warn me.  Once I refilled the reservoir, I was up and running.

3) I have custom built wooden knobs (see my avatar or my post in the shrines thread).  A brass insert came loose in one of them, allowing the steam valve to open slightly, so water was dripping slowly from the wand.  So, this really wasn't an Izzo problem, and in fact, when I was fixing the custom knob insert, I used the OEM knob temporarily (which worked perfectly).

I realize this is an old thread, but wanted to share my experiences. I've read this forum for a long time but this is my first post.

I am very, very disappointed in my experience with my Alex Duetto II. I bought from Chris Coffee about 4.5 years ago. I've had at least half a dozen times when it's sprung leaks and sent water dripping all over the cabinets; it's been back to Chris for service at least 3 times (at nearly $200 in shipping each time).

I'll only go into detail on the most recent one. Machine power failed. Tried swapping out the power switch for a new one, but that didn't work so the machine had to go back. Chris' had it for about 1.5 weeks, ended up replacing most of the wiring that sits underneath the boiler because it had been dripped on over the years and corroded/shorted out.

I got it back about 3 weeks ago...working ok, though seemed to be exceptionally loud when brewing. I came home from work on Friday and found water dripping down the cabinets (again...). There's a steady drip coming from underneath the steam boiler. As I'm taking the machine apart to try to figure out where the water's coming from, I realize that the screw that holds the steam boiler to the bottom of the machine (for stability) is not threaded to the right hole...instead it's just attached to one of the holes in the grate. As I go further, I realize that the 3 screws that attach the pump to the bottom, also for stability, are all broken. No wonder the machine's so loud when it's working...nothing's attached in there! Now, I still haven't been able to tighten the fitting on the bottom of the steam boiler because I can't find a socket big enough.

I've talked to the people at CCS about this and the only thing they offered was "maybe I got a machine from the last day before vacation...it happens sometimes." Overall, I'm quite disappointed in this whole experience. I'm glad it's working out for others, and I may buy a different machine from CCS, but wanted others to know.

Anyone want to buy a used Duetto II that needs some work (I'm only halfway kidding)?
