  1. Thank you for sharing the gasket link, I may buy one someday. Parts are very hard to find, especially the boiler and switches, they were shared with only a few machines that will be rare too nowadays. The main switches were probably replaced by Classic switches for that reason. Bad news about the Gaggia Users Group going down. It was a great resource, they had an archive section with manuals and wiring diagrams. It was they that christened the machine the OWC, it was to distinguish the machine from other Gaggias that were confusingly also called the Gaggia Coffee. Some of the people that were very active on that site still pop up on the Home Barista forum so they may be able to help. Unfortunately I can't find a copy of the wiring diagram, I've had a quick look on the net. I know that I had a print out but can't find it, I'll continue looking for it and will post it if I find it. Wiring a PID is easy as it is not too difficult to work out the pickup points. I have the original manual but it is very generic, no real information in there except for a parts diagram which can be found on the net. I didn't give many later details of the restoration as there hasn't been much interest shown in this thread; fitting the Rancilio steam wand and pressure gauge was fairly straightforward, Ferrari Espresso do a Rancilio steam arm kit that can be adapted ( edit - https://www.ferrari-espresso.com/product/gaggia-pre-2015-rancilio-steam-wand-v3-conversion-kit/) . I replaced the 1/8 BSP elbow joint on the top of the boiler with a 1/8 BSP 'T' piece and used the extra connection to go to the gauge. Good luck with the renovation, I will be interested to see how you get on.
  2. The possible problem with the thermostat is that has failed closed so it won't cut the circuit when it has reached its operating temp. So if you put everything together as is, the thermal fuse may pop again.
  3. It's possible that the steam thermostat has failed, leading to the original overheating. If so, then the thermal fuse may well have blown to prevent meltdown, it's the item inside the clear plastic tube clamped to the top of the boiler. You will need a multimeter to check it. The connections to the thermal fuse are crimped on. Just get a boiler gasket set for a Gaggia Classic for the O rings, you will likely need the smaller rings for the overpressure valve and inlet connector. Don't use just any O rings as they need to be heat resistant, the steam boiler O ring in particular fails regularly due to it operating at a constant high temperature.
  4. I have a Miele CM 5100 BTC machine. It is faulty at the moment but I remember the coffee as being OK but not great. I have loaned it out to people who have thought that it was great so it depends on your experience and expectations. The milk frother is a pain as it has to be removed and cleaned after every use. It seems well put together and is much better than the Gaggia Syncrony Compact that I had before it, but that was a much cheaper machine. I am annoyed that the machine is dead with a fault on the SMPS power supply that is probably just a failed cheap surface mounted component. The PCB also houses the control circuits and chips for the running of the machine so the board is complicated and ridiculously expensive to replace. Later versions had a separate linear power transformer, so if that goes, just the transformer can be replaced. So, as far as Miele are concerned they are happy for a very expensive machine to be scrapped due to poor design that makes repair by replacing internal components uneconomic. I will get the board repaired somewhere (anyone on this forum able to repair SMPS supplies?). Sorry if this does not help your research but it is nice to have an opportunity to have a rant 😄.
  5. @NorvinACS Vesuvius Evo Leva.
  6. I have to say that all of my initial fears regarding the Leva have been allayed and I have absolutely no regrets buying one. When I first signed up for the Leva it was not in production and there was only a prototype in existance. My main concern at the time was that my wife would not be able to operated the double spring lever, there was much talk on the strength required at the time. A bit of background - before we bought the Londinium we asked Foundry Coffee in Sheffield if she could have a go pulling a shot on theirs, and we also visited another board member in Middlesborough (sorry, forgotten your name) to have a try on his Londinium. So, having that amount of concern, it was with some trepidation that I put the deposit down on the double spring Leva. When we first got it, I was pulling the lever with both hands, now that we are used to it I don't even think about it, I pull the lever with one hand, my wife just gets on with it and never complains. So much for listening to people who have never actually used one. Other concerns did not bother me so much; someone asked me if I wasn't concerned about being used as a prototype tester for the company. No, it didn't bother me as the specification and price were right, it is an established company using established technology and as long as I had support from the company I was happy to do any unforseen modifications should they prove necessary. Other concerns- weight on the counter, suck pistons, flexing. ease of use, reliability etc. have all been forgotten now, we just get on with using it to make coffee. A bit like being involved with HiFi equipment as a hobby, eventually you stop listening to the equipment and start listening to the music. Honestly, I can't see me ever changing my machine, it ticks all the right boxes for me and what would I upgrade to? I have now modified my expensive tamper to fit the Leva, reasoning that I won't be needing a premium 58mm tamper for my primary machine again.
  7. Found this last weekend, small elephant hawk moth caterpillar. Another one that uses false eyes to put off predators, makes it look like a kids gummy sweet.
  8. As the thread is a little quiet I'll give an update on the tamper situation. No new revelations here and I am not giving any recommendations on sizes, just giving my experience. I am now using an IMS B662Th26M basket. I turned down my 58mm Torr Goldfinger tamper to fit. I was initially reluctant to change it but reasoned that as I probably won't change my machine I may as well get use out of it rather than have it sit in the drawer. The diameter of the mouth of the basket is 55.35mm but the sides taper after the spring groove. I arrived at the final diameter by shaving a little off and trying it for fit. The diameter of the tamper is now 55mm, (or 54.94mm if you want to (literally) split hairs). It fits the basket but does not go all the way to the bottom due to the taper but goes far enough to compress 18g. Larger diameters will fit but will limit how far the tamper goes into the basket. It is still too big to fit in the standard double basket, so I have one tamper for the IMS and another for the standard basket. The sides of the tamper are tapered to stop it sticking in the basket if it is not withdrawn 'square', and may reduce the suction effect. The 58mm Motta tamper is now 54mm diameter. I shaved it down from 54.2mm (by accident ...don't ask) or so and it is now tapered too. It fits the standard double basket well but is a bit too loose in the IMS basket. I can't say that I have noticed any difference in performance between 54.2mm and 54mm, but that may just be me being insensitive.
  9. Two bits that hold the switch together have broken off the main housing, can be seen to the left and right of the spring in the first picture. That will need to be addressed before the parts can be reassembled - tie wrap? Once you have all the parts on the bench it is not too difficult to see how they go together. The switch looks exactly like the ones used in the Kitchenaid Artisan espresso machines so a spare may be sourced there, you may need to bend the terminals. I have seen them on eBay and Amazon. You will need to determine whether the switch is latching or non latching, both types exist. If it is latching you could always bypass the switch by connecting wires together and using the plug socket to switch the machine on and off.
  10. There should be a rubber valve in there on the end of the spring. The head is machined differently from the 'better' machines so can't be upgraded by fitting parts.
  11. Looking at the pictures it looks as if it is more like the Gaggia Coffee or the Gaggia Espresso rather than the Classic, i.e. it doesn't have the three way solenoid valve or adjustable OPV. The brew pressure is likely to be regulated by a non adjustable valve in the base of the group head.
  12. Thanks for the comments Steve. Perhaps I should clarify that due to the handle having a slight downward incline, the bottomless portatfilter needs to sit on a spacer of about 12mm thickness in order for the handle to clear the work surface so that the portafilter can sit level.
  13. I got this one from TKMaxx for about £7. It has a two way valve and seems to be well made.
