Update: i disassembled the whole thing and reinstalled it and now everything seems working fine.
Also soupy puck seems fixed too.

 

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..

 

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.

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?

 

Something spunds to be vibing

Take the drip tray off and the lid for the resivor and the top grate then try again.

You will need something smaller to catch the drips while trying.

 

Guys is my Bianca kinda loud for rotary pump?i opened it and inspected it closely and nothing seems touching anything.

i think pump motor mounts might be too tight? should i adjust anything? or is it normal?

Hi Everyone,

schoolboy error; was using the larger basket (20g). Have changed the basket to 18g and will try again.

Also, might not have secured the porta filter enough at the start of each shot, as subsequent shots have been at 9bar since I've made a point of tightening a touch more.

Paddle is in the open position as I'm trying to establish a baseline.

Didn't notice the pump pressure, will look out for it now.

 

@Marcusa - I missed one key bit of info from your post. The timing! You quoted 10-12 seconds!

@Cuprajake - is bang on: grind finer, until you are happy with the timing and taste.

 

Hi,

You're too coarse, grind finer and try again

Atm just keep the flow control all the way open till you get used to it.

 

@Marcusa - hello and welcome.

what reading do you get on the pump gauge? Could you please video your workflow so it's easier to diagnose?

slso, with a blank disk (for backflushing) run the machine with the valve fully open. What reading do you get on the group gauge?

 

Hi Everyone,

Took delivery of my new Bianca yesterday and looking for advice on dialling it in. I'm using a niche grinder (which is also brand new) with fresh beans (two weeks old). The niche is set at on 23. and I'm putting 18g into the porta filter, aiming for 25-32 seconds to get 36g out. I've pulled a couple of shots and it's taking approx 10-12 seconds before any liquid appears and I reach 36g in 32 secs, which seemed about right. However I noticed the pressure was always around 4bar, despite the paddle being in the fully open position. To set a baseline (before playing with the paddle) I'd like to be getting at least 9bar and pulling the shots 25-32 secs for 36g out.

How do I get the pressure up? Is the grind too coarse or too fine? I've got the porta filter pretty tight in the head. Am applying reasonable pressure when tamping. Any help is much appreciated as I don't want to waste time and good coffee going down blind alleys.

I think it must different for just about everybody. My Niche is set to around 10 but find I need to grind a little finer (usually half a click at a time) as the beans age. I grind 18g, give it a stir with WDT, slap the portafilter down lightly to level the grind a bit and then tamp until I start to feel the puck give way just a little bit.

Are you using the paddle? I usually have the paddle half way open until I see a few drops (usually after 9-10 seconds) then open it up to 9 bar. I aim for around 33-34 in both grams and seconds. There are times, though, when timing can stretch out to 40 seconds and I can't figure out why. I try to maintain consistency from shot to shot but something obviously changes. Shots are just about always good despite any inconsistencies.

 

Hello, u know how many PIDS are installed on this espresso machine?

There are two independent PID loops and 2 sensors, steam and brew boiler.

 

whos the other suppliers as there is a know rouge about

 

thanks - i checked the supplier forum and feedback on their customer service seems great. seems to be nearly £100 more expensive but after my last coffee machine died, i don't mind paying a bit extra for decent support.

 

2 yr warranty too

 

uk? bella barista

 

Where is the best place to buy the Bianca? I've googled it and I don't recognise any of the suppliers so not sure if it's worth paying a bit extra for better customer service etc.

 

No, you may need to lubricate the seals on the paddle or some scale or debris may have made its way to the needle valve.

 

Guys, is it normal to feel some mild resistance with flow control while moving it around? most of the time its fine and moving easy, some times i feel some resistance.

 

On the video from Lelit insider I posted above.

Check the Bianca video demonstrating the pressure safety features around 2:30 on… it has Bakelite knobs and paddle; (I.e.: not wood).

maybe an option on newer models that Lelit might be considering?

Which video?

 

Get some test trips and see what you're doing. TDS isn't a good measure of hardness or alkalinity.

 

 

How do you make your ro?

 

with RO water filter duh 😂

 

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...

 

Great videos from Lelit insider:

This one compares a standard E61 group (MaraX and the Bianca) - It's in Italian though (ask away if you want to ask anything related to the explanation) 😉

 

Done another 4 or 5 flush cycles today. The grouphead is clear, but I'm still getting particles from the steam boiler.
