Are all of the safety sleeves going into the new models having problems? My machine is supposed to ship soon with the safety sleeve. I’m getting the sense that it might be better to request the machine without it…

None of us can answer that. It has been changed since the very first iteration, I got another and the hole was in the right place, then Andos machine clearly had the hole too far off centre again. I think they really need to get production, sizing and finishing optimised, coupled with better QC testing.

It might be easier to perhaps have the standard system at this time….and buy the safety system later if you feel you need it, or when you personally are confident the issues are definitely resolved. The standard group is a proven product over many years.

Paolo_Cortese About the problem faced form @Ando about the channeling surely it could be a wrong position of the hole on the bottom of the sleeve and make different holes instead of one it’s almost impossible, make 1mm hole on the SS316 it’s a pain in the *** immagine ¾ 0,5mm holes….. in any case we will sort out asap the problem just patient a bit.

I work in Tool & Die as a mold designer. Those pain in the ass holes could easily be done by an EDM Hole popper or Sinker EDM. These are very common in the mold shops, and slightly less common in the stamping die shops. I would recommend you check the tool & die shops in your area to see if they would be willing to do it. The company I work for often does oddball stuff.

Personally… if I were in @Ando’s shoes, irrespective of the machine brand… The machine would be going back in the box and I’d be asking for a full refund. The least I’d expect to do with a new machine would be to reach out to forums, taking videos, pictures, etc. My expectation would be for the machine to work as expected, and free of any defects, out of the box.

A coffee machine is an expensive purchase. It’s very important to be happy with it, out of the box. At the end of the day, the user will be looking at it at least two times a day, and most likely the first thing in the morning. It better be good! No different to a computer, or a fancy mobile phone, or a car (eg).

That’s it. Just wanted to say what I think and what I would do. I hope this issue gets resolved soon and both parties can move on.

Well that’s exactly what he has already done on Friday afternoon..

DavecUK This is honestly my idea of hell - I am the last person on the planet interested in getting into random arguments online with people. And my comment about the pinned thread was tongue firmly in cheek - I had nothing to do with that and couldn’t care less about it.

You have helped me in the past on more than one occasion, for which I am very grateful for.

I accepted you explanation about the scratches etc.. ACS offered me a brushed finish part as a replacement and I politely declined.

They offered me a replacement different style drip tray cover - I politely declined.

Yes - there wasn’t and inch of lube on the safety system - but people can surely get the jist from that, that the thing was absolutely caked in the stuff. It was a nightmare to remove - wedged in far too tight.

Maria has been excellent - in constant communication with me trying to resolve this. They are determined to make me happy here. I can’t really fault that - I think it shows they do really care about customers.

The suggestion that my intention here is to try and damage the ACS brand is absolutely ludicrous and has really annoyed me. I have posted about my issues here, and here only. I was reluctant to even do so right at the start of this, but was encouraged to do so by other members.

I am sure that ACS will sort these issues out and that this will end up being an incredible machine.

I said appear to be and this forum has only tried to help you. I for one got annoyed about how you were reacting to my and other peoples comments, even though they were there to help. I did watch the video (to save you unnecessary work), but didn’t reply fast enough for you. You have to understand I don’t work for ACS and I don’t need a load of hassle.

I even agree certain things are not acceptable for you, or any customer and clearly fed this back to ACS…but “don’t bite the hand that feeds you” is an expression we use. Something you started doing shortly after your first posts. I don’t care if you’re annoyed with me, I basically run this forum to help people and others generally participate to do the same, or receive help.…you need to try and see that. I’m one of the good guys, not the enemy, so please stop upsetting me.

Ando

DavecUK Each to their own - I do care what people think though, so if I have upset anyone, including yourself, then I apologise.

Yesterday mornings post from myself is an overreaction from myself, and I shouldn’t have posted it. Could have handled it in a much better manner. The only mitigating factor I can put forward is that I hadn’t slept a wink with the stress of this, that’s not an excuse, just a contributory factor to my reaction.

I know full well that you help people - and have thanked you multiple times for the help you have given me over the years.

As far as the safety system goes, wouldn’t it be simpler to add a 2nd ~~shower~~ distribution screen between the group and the shower screen?

Not really, I had thought about it but there isn’t room, they just need to get the little hole in the right place, then it works fine.

I had thought of a metal disk under the shower screen also held by the screw, but it would have to be relatively otherwise it would get distorted and push down on the screen… mind you the idea is still there in my mind

Loonster

I also have similar problems. I should remove the shower screen to verify.

DavecUK

Loonster For sure, remove the screen it doesn’t look right.

the only immediate and easy fix I can think of is to get a thin, but strong steel washer that goes under the shower screen and is just wide enough to cover the hole..might work? Trouble is…. finding one, especially as the screens center hole has a pushed up edge, so the washer needs to have a large enough hole to avoid that part.

I might look and see if I can find a suitable washer and do a test on my machine…although mine has no problem, I can at least see if it works.

Possibly something like this, but I need to do some measurements next time I remove the screen to clean it.

If it works well, it might be something ACS can add as a standard part to the system, rather than try and get the hole really close to the bolt hole? Especially as it’s only 0.1mm thick 304 stainless?

Loonster

I measured the distance from the hole to the tapped hole. It is about 6mm. Looking at the shower screen, that would place the hole in the flat area.

I did notice something while putting it back together. The shower screen does not fit inside the recess.

I need to find my calipers to find out what is out of spec. May just sand the screen to make it fit.

(The screen being flatter may be due to dosing 16g in the double basket. Not sure. Cheap part, may just replace with a new one. )

The IMS shower screens are thinnish but fairly strong. It looks as if yours might have been flattened by putting too much coffee in the portafilter, the centre cant flatten and digs into the coffee which is pushed to the edges. There it flattens the screen….which means it won’t fit in the recess.. As I said I dose 16g and it’s OK, I never see a screen or, have seen a screen imprint. However that height when tamped varies with coffee density. 16g of a very dense coffee won’t fill the portafilter as high.

Here is how mine fits.

It’s worth truing a test fit without the screw and see if it clicks in, as it’s possible the screen isn’t quite cantered, as there is a little slack in the hole for the screw ()as there has to be)..

MacPhisto

Mine has a similar hole to hole measurement. I haven’t observed any corresponding puck disturbance.

The safety lever system works as expected with one notable exception: following a backflush, the exhaust valve occasionally takes extra time to close. Which means that no pressure will build in the chamber and the safety system will not function. I’ve found that I can hear a click about 30 seconds after I backflush which is likely the valve closing. If I pull the lever again before that, the pump activates for preinfusion but the water is diverted straight to the drip tray and the safety system wont function.

Probably a timer on the valve after the signal is received to keep it open? Backflushing with detergent is probably the only time I would pull shots under pressure and activate the release valve with a short enough interval to notice this.

No the exhaust valve doesn’t occasionally take extra time, it’s programmed to open for 30s to ensure the puck and everything drains down properly. The display flashes the brew time whilst this happening, when the exhaust valve closes it stops flashing. I still need to do a user guide.

I have asked if an extra function can be programmed in so if you press the middle button while this is happening you can cut the 30s wait short and be ready immediately. If it can be done it should be able to be done by an over the air flash via a mobile hot spot. It’s not super critical though unless your prepping and pulling shots inhumanly fast.

However when backflushing it can be a pain, especially when using the method I will advise in a user guide…because it simply takes longer. I am experimenting with 2 different backflush methods. to find the best one. However you won’t need to backflush very often, once every 6 months or longer.

Loonster

I don’t think it is possible to unflatten the screen. Took a Dremel to the outside diameter. Now it fits very snuggly, with a slight interference fit. No screw required.

Now to wait 9 hours to test it out…

DavecUK

Loonster Now to wait 9 hours to test it out…

Err, you have to have the screw, absolutely have to have it!!!

otherwise the safety system no longer works

Loonster

DavecUK Of course I installed it. Just emphasizing how tight of a fit it is for the picture. ;)

ManicAsif

@DavecUK , I cannot for the life of me figure out how to send a direct message! can you please advise, I would like to message you directly please

Thanks
