Is my Duetto now scrap?


Recommended Posts

Had my Duetto ii for 10 years with no major problems apart from changing the opv a few years ago.  Recently it started struggling to pull a shot (not reaching pressure).  Took it to a local tech who replaced the pump, safety valve and anti vac valve. He also serviced the hot water valve and level probe.  Got it home and it had an issue straight away.  Really low pressure at the start of the shot before kicking in properly.  The next day it was worse.  I have it on an automatic timer to be warmed up when I use it in the morning.  Tried to use it and no water came out at all.  Switched it off and left it to cool then tried again.  This time it was like when I first brought it home.  Obviously contacted the tech again.  He's now taken it to bits and says there is major scale everywhere but worse is that the steam boiler is unsafe as it has leaks and wants to replace it but can't find the part.  Is it time to think about a new machine?

Potentially. Looks like your machine has reached end of life... not because the machine is not good, but it seems that, sadly, you haven’t given it the maintenance / treatment it deserved over those 10 years. You may try and contact Gruppo Izzo or take it to Bella Barista who carried stock and parts, and were the authorised UK dealer for them for a while. I’m not sure it’s still the case, but they can at least put you in the right direction.

Limescale is the biggest espresso machine killer. So, whenever you fix it or buy a new machine, try to avoid it in the first place by putting “boiler friendly” water inside your machine.

on a positive note, coffee machines, and grinders, have come a long way since. There are great options out there to choose from. 
 

welcome to the forum, and good luck!

Thanks, that's sort of the conclusion I've unhappily drawn to as well.  I only used filtered water (a scale reducing filter allegedly not brita) and descaled regularly with citric acid but our water is incredibly hard here.  Lesson learnt the expensive way 😕  Looking at BB it seems they aren't doing Izzo any more.  What would be a good replacement machine?  Sage dual boiler,  Lelit, Profitec (who I believe were LCM) or a Crem one (Expobar?).  I'm a bit out of the loop!  Btw what is profiling and all this needle valve stuff.  I've got 10 years of catching up to do 😁

Haha! 

A great starting point... Here:

https://coffeeequipmentreviews.wordpress.com

It depends what you want and your budget. 

I had a Profitec P-700 in the past (PS: ECM is still going, Profitec is a sister company on the "less-expensive" side. Think VW and Audi. I know have a Lelit Elizabeth. 

See what takes your fancy and go from there! 

Question: How can you resit upgraditus for all those years???? In less than 10 years I had 6 coffee machines!

Hahaha, the coffee setup is about the only thing I never succumbed to upgraditus to in the house 😁.  It just worked perfectly for what I wanted so I never thought about a new one.  Thanks for the link I'll have a look.  Grinder wise I think I'm ok as I have a macap mx which is probably overkill for my needs but I got a bargain on ebay

You may want to revisit that 🙂 - Have you heard of the Niche Zero?

🤣🤣 Just googled it.  This could be an expensive couple of months!

Hope you get sorted. Lots of great machines on the market to choose from now.

It is a bit odd that the tech didn't spot such major scale problems and an unsafe boiler the first time around?

Time to find a new tech or repair it yourself.

A decent engineer would have found the faults first before changing parts willy-nilly.

You could replace it, but i would guarantee somebody on here would buy your old machine as is and have it working without much effort and at much less expense than a new one.

If you get a new machine you will want to factor in the cost of supplying treated water to it to avoid this happening to the new machine. As a quick aside, the Sage Dual boiler and those type of more complex modern machines will suffer from scale more than the classic style of machine. I had a Sage DB and it was a good machine but descaling it was a bit of a PITA when it went wrong. I don't know if they have fixed it but a common issue with with the descale port clogging. The actual process of descaling it is super easy but it was definitely hit and miss.

I did think the same thing myself.  Especially as it was a brew issue not a steam issue but then thought he may not have seen it because of the insulation or am I being a bit naive here?  🤔

Definitely don't scap it!

Depending on price and location I would be interested.

Am still waiting to hear what he has to say.  Definitely thinking he he might be taking me for a ride now though 🤔

Already have a decent lever (L1), E61 HX (ECM), SBDU (OWC), just looking for a decent dual boiler (not counting the Kitchenaid) to complete the set 🙂

Would be interested in this myself if its going to market....

I suspect the tech has fu**ed up something in his fiddlings. Perhaps opening and closing the boilers without cleaning and sealing?

So here's some pics of the steam boiler he wants to replace.  Not sure how this would repair the brew pressure issue but if the inside of the pipes looks like the outside of the tank then probably explains a lot.  An osmio zero reverse osmosis kit and a Lelit Bianca are looking very good right now 😁

So he's now saying that he doesn't know if a new boiler will fix the problem but as both boilers are linked one could affect the other?  Oh, and he's also said the size of corrosion patches are why he thinks the boiler is leaking and not a joint or pipe.

I suppose that the only way to find the source of the leak is to reconnect everything and apply a little pressure inside the tank, probably too expensive to pay someone to do it for you.

Still, looks to be a good project...

I would not scrap it. Get a second opinion on the condition of the steam boiler. The problem you describe as low brew pressure at the start of shot sounds like the pump pressure regulation sticking. 

Unless you believe the marketing, there has been very little substantive progress in the performance of coffee machines since your Duetto, with one or two notable exceptions like the Decent, which can control both pressure and temperature. . For e61 double boiler machines the real progress includes either a variable flow pump or a variable orifice to achieve flow/ pressure control. You can fit a variable orifice needle to your Duetto to bring it up to date.

Thanks for the advice.  I'm going to get him to put it back together as is and then get it back off him.  I don't see the point in paying for a new steam boiler as it didn't have a steaming problem when it went to him and I can't see how it will fix a pump pressure problem.  Might have a little tinker myself when I get it back 🤔

That kind of external discolouration I had on my old Alex single boiler just from the spitting of the anti vac valve. It wasn't reflective of the internal condition. (though it does look rather more substantial than mine was around the fittings.

BB still do Izzo parts and will get them for you unless thats changed in the last 2-3 months. I wanted some parts for my Alex at the time and also a spare Alex MkII. 

Actually I still do for the spares/repair (or the chap that bought the Alex does); a top panel and the cup tray, I may look for another spares or repair machine on here and ask BB about the parts.

Well that's all a bit odd.  Picked up the machine today after he put it back together and it seems to be working fine at the moment.  Brew pressure is a little low (8 bar) but it hits that straight away.  I'll see if the problem reappears when it's been on a while but it seems the tech has inadvertently fixed it!😁
