    New Phone?

    Been on an iphone X for the past 2 years and iPhones since the 4S. Still love them and still think they are the best overall phones. The X is still very fast, will get updates for the next 3/4 years at least and does everything I want perfectly.
  2. You have to remember that established brands with a good name sometimes have a tendency to rest on their laurels and some of their machines are a bit outdated or missing some nice QoL features that newer machines have. They will make good coffee for sure but they have been superseded by newer models. How much did you pay for the Rocket Mozzafiato Type R @Espress-Oh if you don't mind me asking?
  3. I never underestimate: A) Peoples ability to be utterly retarded B) Peoples inability or unwillingness to look up or simply ask someone else when they don't know what they are doing. Truly, it boggles the mind. We have the internet and yet people still think "I didn't know how to do X so its not my fault I did Y" is totally OK and not their fault.
  4. I would think carefully about getting any sort of manual espresso machine for an office personally. Unless there are only a couple of you that use it and you are all willing to do basic maintenance and clean up after every shot it will be a nightmare. People won't fill a reservoir, people won't tap out the portafilter or rinse that and the screen after each use. Someone will mess with something and either create a huge mess or generally make it so the machine can't be used until fixed. I don't know if I am being overly pessimistic but people are lazy and won't take the 1 minute to do the post coffee cleanup.
  5. That depends if a decision was made to change the style of fitting because of a known issue or simply as a more permanent fixture. A plastic washer is not a great long term solution whereas some sort of thread sealant is probably much better. I can’t imagine that it was changed for malicious or nasty reasons. The number of beta machines is tiny and there would be no issue with contacting the owners and saying “there can be an issue with the bolts, here’s some replacements. Replace them if you wish.” I haven’t seen anyone else with the same issue so it’s clearly not a massive show stopper. I feel like plenty of machines will change over time from their first iteration. Time exposes issues and weaknesses and things you don’t necessarily foresee. I’m a software developer and you would be amazed at the inventive way people break software. When you build something it’s easy to have blind spots when it comes to how people might use your product.
  6. I don’t use the hot water tap very often in general. The amount of scale in the boiler was very minimal when I looked in there as well.
  7. The machine is fixed, cleaned up and back it one piece now. I ended up buying replacement stainless steel bolts to go into the bottom of the steam boiler and those coupled with PTFE has fixed everything. The reason lots of PTFE wasn't working was because the threads on some of the bolts had perished. I believe that on the production machines these bolts are coated in something which removes the issue but on the beta machines they are held in with the threads and some sort of washer (plastic maybe). Due to the material the bolts were made from and the nature of an increasingly (I can't remember which way it goes) acidic or alkaline solution from constant heat applied to a relatively stale body of water, the threads weakened and broke in places leading to the leaks. Replacing the bolts was very easy and although I got very frustrated on the way to the solution when simply re-using the dud bolts and lots of PTFE didn't work, the replacement bolts sorted the issue very nicely. Dave helped me with the bolts to buy and explained how to install them without causing any damage to the boilers threads as the bolts are not a perfect 1:1 replacement for the originals but they are very close. Apologies for the lack of responses for a few days but I have been busy and only just got everything put back together this afternoon after fixing it yesterday. The rust etc cleaned up fine and most of it was just deposits from a few parts that actually rusted like a bolt that held a couple of cables to ground on the case. I'm sure that I have got some of the above incorrect from a technical standpoint but that is my basic understanding of the issue.
  8. I have emailed Paolo about this and have taken various bits of advice on board from this thread so thanks for everyones input. I will report back once I have fixed this which should help others and allay any fears people have about the machines.
  9. As you can see in this picture, albeit not massively clearly, the thread on this bolt has snapped off in places. I wonder if this is why its not sealing up any more.
  10. Its not good in places but some of that is just staining/rust water. Not super impressed in general as more than one of the bolts is leaking and its proving hard to get any sort of seal on them now. I just tried again with 8 wraps of PTFE and its still leaking.
  11. Thanks as always Dave. I'm still confused as to how you would remove the boiler without removing the bottom plate. To remove the boiler you have to remove the various gubbins at the top of the boiler and then you have to remove at least 3 nuts from various pipes going into the bottom of the boiler. Those nuts at the bottom are inaccessible with the bottom plate still attached. I'm not talking about the 3 legs the boiler sits on that bolt through the bottom of the case, I'm taking inlet/outlet pipes and connectors. I have contacted Paolo about this to see what he thinks but for now I will have a look at getting some of the above copper o-rings.
  12. Sorry, its all got a little convoluted. So initially I took off the pressure sealing bolt on the top of the steam boiler to drain it. See picture 1 with the broken washer next to it. That seems fine with some PTFE tape on the thread even if I wouldn't expect a washer to perish with less than a years use. That was just an annoyance and not the cause of any problems. The issue is with the blanking bolts at the bottom of the steam boiler leaking. Picture two is of the seal that has cracked and I have removed from the nut. I have put anywhere between 2 and 5 wraps of PTFE tape around the leaking nuts with no success and every time I do this it takes a few hours because I have to wait for it to heat up and cool down between tests and if I want the machine to be a little easier to manage I am filling and draining the boiler each time. Im making sure I wrap the PTFE the correct way around the threads. The only way to work properly on the bottom of the boiler is to completely remove the bottom plate as there are a number of pipes and connectors that go into the bottom of the boiler that connect to the rest of the machine. Without access to undo those, you cannot remove the boiler or access many of the parts of the steam boiler at the bottom. The plate the water bottle sits on bolts into the floor of the machine and doesn't connect anywhere else. The same with the steam boiler. The steam boiler is held in place by the three legs bolted into the bottom plate along with the various pipes that link it to the rest of the machine. Does that make sense? Ive added a final picture circling the bolts on the bottom that are causing the leaking.
  13. I have had a good look and brought it up to pressure a few times and its a couple of the bolts in the bottom of the steam boiler that are leaking. As Rob says, the washer has perished (cracked completely through in one place and generally cracking throughout) and this is letting water leak around them. I have tried to stick a load of PTFE tape around the leaking ones but so far I haven't had any luck getting them to seal properly under full steam pressure. Part of the thread on one of the nuts is snapped as well. There is definitely some scale in there but i think its very very minimal. Literally just stuff that is suspended in the water as apposed to caked on the inside of the boiler. As above, its the bolts that blank off three of the holes in the bottom of the steam boiler that are leaking. The OPV venting is very powerful and does splash a bit but I haven't had any issues with that beyond the usual. The service boiler is usually on quite a lot. Probably from about 8:30 in the morning through until about 4:30 sometimes. Other times its off for half that time. Sometimes I use the hot water tap but perhaps a few times a month. Not going to lie, for the price I paid it is a steal but working on this thing is a bit of a nightmare. My beta machine doesn't go together that well with lots of pushing, torsion and goading required to seat various screws into their threads and you have to take the entire bottom plate off to work on it which in turn lets the electrics, steam boiler and water pressure plate float about. I am somewhat concerned that I will have a wire touching a very hot piece of metal somewhere as a result. I think I would have preferred the minima to be a little larger and a little better laid out. Like you, I don't know if I would get another if this one packs in.
  14. Pictures of top of the boilers. One other thing, I took the bolt out of the top of the steam boiler (one with the collar, i think it allows air to escape as pressure build) and the washer underneath just disintegrated. Any idea where the best place to find a replacement is? Is this something I should be talking to ACS about or is it a generic washer I can buy from anywhere?
  15. Its the beta machine that Dave had for testing so I think its probably identical to the other beta machines. Didn't check when it arrived but it wasn't leaking then and it hasn't been leaking for more than a few months as the machine was moved a few months ago and there was no residue or wet patch underneath. Water is tesco ashbeck alone. Cheers Dave, I tried to get as good pictures as possible but without removing the entire boiler that is almost impossible. To my eye the top looks fine but I am just adding a couple of photos. One of the steam and one of the brew boiler. There is stuff around the right angle (copper pipe) part but there is the same stuff on the brew boiler as well. I assumed that was normal. Sounds like I need to get it apart a bit more, clean it up and then we should be able to check it out a bit better
