Hi Browdo, glad I am not crazy here! I did 2-3 tank flushes as suggested here, and it go better, clearing up like 99% of the particles but not 100% clear.

Over the next few days I've been testing daily. Same issue but not as bad as the first time. Still seeing these particles and yes--they do stick to a magnet each time 😕 .

Hope your machine is fine and ours was just isolated. Also read some Bianca users suffering a similar issue, but their water was really grey and gross?
 
The exit pipe from the boiler is not right at the bottom, but a little raised....so the 3 flushes may not get it all....try a few more if you want, but there are 3 important points.


  • It won't be in the steam

  • it won't be in the brew water as that runs in a separate HX unit, which holds about 160-180 ml of water and has so much water through it would always be clean

  • Don't use hot water from a machines boiler, it's not best practice...use a kettle. (warm cups with it is fine)
 
@Browdo - To my eyes... The only purpose of the hot water tap on an espresso machine is to drain the boiler / cycle the water now and again. With that water, yeah, feel free to make an Americano if that's your thing.

Dave can explain the rationale behind not using the water tap in a frequently basis, as he knows way more than me. 🙂

Ever increasing TDS as you steam, water in large boiler for days, continually reheated....possibly not ideal for americano or tea. kettle seems so much easier and less worries about the machine.

Here's what Lelit had to say via email:

"without seeing the machine and all the factors involved it's also difficult for us to give you an exact answer or solution.

Our LAB experience shows that the water used with these machines also has a very important impact on the internal components. In our previous e-mail, we have invited you to check the water profile. We would also invite you to use bottled water with these values:

pH: 6.7-8
total Hardness 70-90 ppm CaCO3
alkalinity 50-70 ppm CaCO3
Clorides < 30 ppm
Sulphates < 30 ppm

And check if the problem persists after 2 months of constant use."
 
...And check if the problem persists after 2 months of constant use."...
Well it's a choice then i suppose, either do as instructed in their e-mail r.e. water....or.....r.e. your previous Quote :- "Need to get a replacement now!"

.....2 months and it "may" (not saying that it will) still be the same....2 months wasted.....if it was mine then the safety of my family would be my reason for it going straight back.....your machine; your choice.

Best of luck with whatever route you decide to take.

Yeah, I have already initiated a return of the Mara X for a full refund. Already ordered a Profitec Pro 700 :D

Mara X looked nice and all, but there is no excuse to have metal coming out of your coffee machine. People can make all the excuses they want but for a new machine seeing filtered water 2x, not acceptable.

That was quick...agreed it's just not cricket; i've slightly changed my opinion now about Lelit....hopefully it was a "one-off"

That Profitec Pro 700 does look nicer...2 gauges is nice...3 gauges (with a flow-control-kit) is "eye-candy" to me...YMMV :classic_smile:

I agree with you on the changing opinion about Lelit...seeing Bianca owners with the similar issue also was not a good sign. Didn't opt for flow control...not quite there yet, but double boiler will be nice!! :D
