Hey Biancanas,

I received my Bianca today from DHL after receiving 2 Elizabeth's with 2 different issues, while i'm very excited upon unboxing it and checking it, i noticed the rail frame under drip tray is slightly bent 😭( probably DHL threw the package or dropped it) despite being double boxed. well the issue is not huge just really annoying as it is not a cheap machine its jsut causing the drip try to wobble a bit.

at least everything seems working fine for now, i might try to straighten the frame. any suggestion?

Not good, id get on to the seller. This should be covered by warranty from dhl

Its a stainless steel fram so not going to be the easiest to bend back.

@yahyoh - I agree with @Cuprajake here. I have to say, you had your fair share of bad luck with coffee machines, I grant you that.

However, its not your fault, it's not your responsibility to ensure the machines gets from A to B as it should. That's the responsibility of the currier, and the reseller (and you) pay a good price for that service.

It should be fixed. Don't accept something you are not happy. Despite all the bad luck you had, it's not your fault.

Honestly i'm not even sure if the replacement going to arrive in a better shape, at least the machine internally seems fine for now? couriers dont give a f how expensive the machine is. i kinda think the broken Elizabeth's i received the couriers fault for poor handling. lmao im scared to ask for a replacement which might arrive in worse shape!

@yahyoh You go back to the seller. That isn't acceptable. It's the only way things will improve.

Just to help me out can you pm me photos of all the packaging that was used. I have a little work I'm doing on packaging for espresso machines and it would help me.

actually the reseller offred me to return it. im kinda hesitant as the issue is not something affecting the performance of the machine and the replacement might arrive in worse shape or with something broken internally. honestly such heavy expansive machine should be shipped on pallet oh well.

sure i can PM you the packaging pics.

BTW My bianca came with baskets made by IMS. even the blind basket.

Also for some reason im getting testier espresso than Elizabeth honestly using the same coffee and temp, despite not using flow control much. 😃

how loud the rotary pump should be? i expected to be quieter honestly. like its not very loud but not very quiet either.

Lies! Total lies! 🤣😂 - You're making jealous and wanting to upgrade! 🤣

Haha , machine design honestly looks like way better than Elizabeth and it is very heavy like around 25-27kg i think. Everyone coming around complimenting how good it looks.

also, yesterday i did 5 shots back to back and temp was really stable.

Steaming 200ML milk at 2.5 bar takes around 15-17 secs ( you have to be really good with technique 😂)

Guys do you think it is normal to hear the pump like hitting something once it stops while refilling steam boiler( it doesnt happen while brewing), do you think it needs tightening. it actually my first rotary pump machine. also how loud it should be? as i expected it to be almost silent compared to Elizabeth 😁.

Guys do you think i should use the lelit water softener if we im using RO water on the machine?

water here is kinda hard ( i never tested it actually) but we get scale build up on shower heads and mixers etc...

If you are introducing minerals back into the water...that's not good, you might as well add sodium or potassium bicarbonate to increase the TDS for flavour reasons...at least it's non scaling.

If you mix hard water with RO using that Tap valve the lelit water filter is simply going to change calcium carbonate which scales to sodium carbonate, which doesn't. A rather wasteful excercise.

Actually we are introducing some TDS back for drinking water for health reasons as recommended by water experts? i think 😅

is it bad for boilers to introduce back some TDS?

Although we have been running the same water in stainless steel kittle which doesnt have any scale since 3-4 months . I think i might get water hardness tester strips to be on the safe side.

Hey guys,

I was back flushing and cleaning & lubing my Bianca today, after doing the lever cam, moved to flow control. Upon removing it. i noticed some green stuff on the sides and the threads and some white stuff on the "jet" i think its called?

which seems scale?? even though I'm using RO filtered water with hardness around 20-25 ppm as per the tester below, where TDS is around 120-140 ppm.

https://i.imgur.com/6a12t1I.jpg

this scale seems affecting the flow control which making it impossible to close fully. should i be worried about the boilers? even tho the water is not hard as per the tester. Im really confused.

If you are using RO, where are you getting the TDS from? Scaling minerals? Salts? Corrosion?

Actually the RO system has a valve where you can reintroduce some TDS based on how much you open it, where it was set to around 120 PPM as per the TDS meter. which is good enough for drinking water and good Espresso extraction right?

That's not what I asked. 😊 - well, you partially answered the question. But do you know exactly what you are allowing through? In other words, if there's calcium and magnesium, it might well be limescale.

But isn't using fully filtered RO water without any minerals is not good for good extraction?
Guess the water hardness tester strips are not enough?

i might just send a sample of water for lab testing as it can be done FOC from the RO water filter company 😁

MediumRoastSteam said:
No no. You are missing the point. You want minerals, but not minerals which will cause scale - sodium bicarbonate and potassium bicarbonate are examples. Add 100mg/L and it will act as a buffer to avoid corrosion and will also conduct current so probes and sensors will work just fine.

No scale ever again. Been doing so over 2 years.

Do you think using bottled water will be better?

Hey Guys


I have been having some issued with E61, where it seems exhausting some water while brewing since i did backflushing and lubing the whole thing!

here's a test while using blind basket

i already removed the lower part and reinstalled it but still the same, moreover ive been getting more wet pucks since this issue started.
Can you guys help!

Thanks

edit: i'm thinking about redoing it all, i will remove the lever\exhaust and inspect everything..hopefully nothing is messed up..
