  1. Hi all, I've had a used Gaggia classic (2005 model) since christmas and having gone through a full stripdown, service, descale and rebuild I'm now trying to work out if my solenoid is functioning fully. I took the solenoid apart as part of the service and after recomissioning the machine and pulling a few shots, I noticed a small puddle of water around the pump/back of the machine internals. With help of a mirror, I could see it was the solenoid weeping out from where the brass 'post' screws into the brass bottom part. Having trained as a plumber I decided to use PTFE tape to seal th
  3. Hi all, after recent descale of my classic I have lost water pressure through the group. I have been using a water filter jug which I know doesn't help much with scale, my bad. I have stripped the shower screen and dispersion plate and cleaned but still no water pressure. I did another descale and this cleared it and water pressure returned. However on returning the dispersion plate and screen the water is again struggling to get through. The pump initially kicks in normal volume then goes to a quieter. Could the pump be the problem or is it likely the solenoid ? The steaming arm i
  4. Greetings from Canada! I'm overhauling a used classic (late 90's gold model) that I recently purchased and it seems that the solenoid valve assembly is missing the main o-ring seal. It looks to be around 18mm in diameter but not sure of how thick it needs to be. I do know that a 2mm ring is way too bulky and wont allow the valve housing to thread back into the base. Finding a 1mm o-ring in that size is also proving to be a challenge and I'm not even sure that's the correct thickness. Any advice would be great. Thanks.
  5. Had my DB serviced and repaired today by Coffee Classics as it was leaking steam. Glad I did as it needed a good going over by the sounds of it from the Engineer. Leaking steam was fairly obvious but the main buttons on the front had a slight electrical buzzing noise when pressing at times. Basically the machine had a new solenoid valve, hot water tap needle valve, complete set of o-rings and boiler probes cleaned. Also carried out a de-scale whilst the engineer was here, which I'm so glad he did due to this being problematic with these machines. Mine had the problem of displaying 'valves
  6. Afternoon all, new user here, after experiencing a lack of water flow through the head (it does come out the wand) I'm trying the clean/descale the solenoid. However I can't undo the top of the valve from the section that attaches to the boiler. I have the electrical unit off just the last part to get to the pin head section I'm struggling with. Anyone have any tips to do this? Is it a case of having to use a vice? Many thanks, Duncan
  7. I just finished a full teardown and rebuild of a Gaggia Classic and it's not pulling water through. Seems to be the solenoid valve but I took it apart and descaled it. Any ideas on how to troubleshoot? I'm a bit stuck now
  8. Hi, I am the longtime owner of a Gaggia classic (7 years), and due to a fear of taking things apart have never given the boiler and solenoid a good clean before. The water flow through the group head has stopped (water and steam through the wand is still fine), so I took out the solenoid and gave it a good clean. Putting it back together was fine, but the water continued not to flow. I then replaced the pump, as it had been sounded a little weak of late. Still no water flow, so I took out the boiler to give it a good clean. Unfortunately, I can't open the boiler up. The bolts just won't g
  9. A question for the Gaggia tifosi. I noticed the third blade has no plug connected to it. Is something missing in my Classic Does it have another function like an earth wire perhaps?
  10. Hi all. I put up a video here with a problem with my Gaggia Classic a few days ago, and the consensus seemed to be that the solenoid valve had gotten blocked with scale debris. The machine is 2011 but new to me, bought second-hand recently. I have been trying to get myself set up over the last month or so, getting a second-hand Baratza Vario from a forum member, tamper, scales, airtight container etc. Also got a brass shower screen holder and gasket as the originals did not look too good. The issue occurred, I think, after I put the machine on its side, to fit the new parts. (Reall
  11. Right so, need a couple of things clearing in the old brain pan about my Gaggia Classic please folk. Back flushing, is it really necessary to do that, wont it force crap into the solenoid and end up blocking it!? This takes me to the next thing, the solenoid, mine is still the original solenoid, where do we source the upgrade larger solenoid and does any one have any idea how much they are!?
  12. I have always experienced a soggy puck after pulling a shot. Could this be a solenoid issue....? I.e. The solenoid isn't closing off quick enough following turning the water off? If this is the case, what would be the suggested remedial action...? (Gaggia Classic) thanks Paul
  13. This week I bought a used Gaggia Classic, and to my dismay there was hardly any flow through the grouphead. Thankfully, the forums have been a great help, so I cleaned the grouphead, and when that didn't work I opened up the machine to clear out the solenoid and descale the boiler. However, I've run into a little bit of a problem; I can't for the life of me undo the nut on the solenoid valve. Does anyone have any tips for undoing it? Or could I just leave the valve in some descaler and just hope for the best? Thanks
  14. Just replaced the steam valve and it now seems the solenoid is looking dodgy. Steam coming from the head and for some reason the flow has suddenly gone all constipated even though I haven't changed beans or grind it is struggling to push out the water taking well over a minute to get to 28g from 18g and that is even if I don't put any pressure on the tamper but only nutate to even out the coffee grinds. Really can't afford to get another. So can they be taken apart and descaled or whatever you need to do? I have back flushed descaled etc but to no avail. I've noticed the steam valve is sp
  15. Are you supposed to change the group gasket regularly? Or is it OK to only change if there is a leakage or problem? I have a Silvia V3 and had it already many years and never changed the gasket. I don't have any problems just wondering if I should change it more often. On ebay I can see two kinds of Silvia gaskets. Regular ones and Long Life. Would the Long Life gaskets be a better choice? I also wonder about the 3 way Solenoid valve, should it be disassembled and cleaned regulary? I do the back flushes every week, but wonder if I dare touching the inner parts and clean them?
  16. Hi, I'm sure this should be obvious, but... I've just acquired a Classic from eBay. It's a model R18161/40, dated 2012, and I *think* it should therefore have the 3-way solenoid valve. It has the tube going down into the drip tray, which I've seen described as a reliable indicator, but I was a bit thrown by another website's recommendation to listen for the click of the valve opening after you hit the brew switch - I just don't hear that! So before I embark on backflushing and wreck the machine, what's a failsafe test? (I have taken the top off, but TBH I'm not sure what I'm lookin
  17. Hi guys, I'm new to the forum! I bought a second-hand Gaggia Classic a few weeks ago, which was working fine for the first couple of weeks. About a week ago water would stop coming through the grouphead, which seemed to be triggered by trying to backflush the system (which I had done successfully once before) or when putting additional pressure on the system (e.g. When making a ristretto). In both cases, the pump noise would go very quiet and water would stop coming out of the group head except in very small occasional drops. Water/steam was coming out of the steam wand as normal. Af
  18. I know this will bore the tits off everyone but I'm at a dead end. So- water from wand but not the head. I've had everything apart. The OPV allows flow back into the tank. I've took the 3 way valve apart all seems ok. I've took the boiler apart and all seems to flow ok. I switched the machine to make coffee with the 3 way valve removed and water came out the hole for the valve. I tried the machine with the moving part removed from the 3 way valve and still no flow. Am I right or wrong in thinking that water should either flow out of the head or into the drip tray? Now I've had it all a
  19. I just received my Gaggia Classic and have been using it for about 5 days now. After seeing the demonstration on you tube of my machine, it appears that my Solenoid valve is not working properly. After I shut off the brew switch, it still leaks water out of the portafilter. The online video shows the metal tube purging the water into the drip tray as soon as the brew button is shut off. Also, when I remove the portafilter, the top of the coffee puck is full of water, is that normal? It doesn't look like anything is being purged from the tube when I make my espresso, it leaks out of the portafi
  20. Without wishing to tempt fate I thought I would share my successful fix of a problem for future reference. I've posted before in a previous thread titled 'Problem with Gaggia Classic: flow stops when heats up', but actually I think this is a generic problem that could affect many types of machines. My own machine is an old Rancilio Nancy, (one of the predecessors of the Silvia), and probably dates from the mid 1980's. Around New Year it developed a problem where no water would come through the group head along with some odd sounds that I assumed were due to pump failure. I made the mista

    Classic OPV

    I've been having some issues with my gaggia which I'm trying to narrow down to one of the elements. I just did some tests and found out that no water is coming out of the overflow pipe attached to the OPV. I tried that with 1) a blank basket, 2) finely ground coffee which barely comes out of the portafilter, 3) coarsely grind coffee which gushes out of the portafilter, and 4) hitting the brew switch while the machine is in steam mode. In neither of the 4 cases did I get a single drip out of the OPV. Is this normal? I fail to understand when should water be coming out of the overflow pipe.. Tha
  22. Total newbie but been doing a lot of reading I understand there are 2 types of Classic or maybe Gaggia`s in general. Pre Phillips take over and post Phillips take over. What is the difference or changes and where they improvements on post take over models if any and when was the take over ??? thanks
  23. Hi All. I have a Classic Gaggia, 4+ years, have descaled it rather regularly. The frother has steam coming through it fine. The water that goes through the basket doesn't come out at all now. My husband took out all the parts he could and cleaned them, put them back. It worked temporarily but now nothing. I'm going through espresso withdrawal so can someone help? I'm in Surrey, hard water area. Does anyone get water delivered in big kegs in this area I'm wondering to eliminate the scale problem? THanks all! I'm new to the technical part of espresso but love it as a consumer!
  24. Hi folks. Been looking at the forum and intend to retire my Delonghi and get a Gaggia Classic. My question is, if anyone can shed some light, what is the difference between a Classic with the chrome tube going down into the rear left of this drip tray and one with no tube. There also seems to be another Classic with the code ending BNC. Where might I find a reference to the different codes. Is there a particular variation that is better than the others. I know it's Saturday evening, is there anybody out there that can help?
  25. I have a Gaggia Baby Class that I bought as ex demo stock. I've just hit a problem whereby no water is coming out of the group head. The steam wand IS working, and when switched on the pump vibrates. It had never been descaled properly and I was hoping that a descaling cycle might just sort it out. It didn't so reading all the instructions on this site I have removed the boiler and cleaned all the scale build up out of it. So my thoughts now are that it is the 3 way solenoid valve that has become blocked. Some posts on this site mention about splitting the 3 way down to clean
