    Silvia loud clicking noise

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Ive had my Silvia about 10 months - just yesterday it started making an occasional loud clicking noise (usually a few clicks in quick succession) when I am pumping water through the group (either making coffee or cleaning). Im not sure whether its something electric or something wrong with the pump, Im thinking the latter but am still weary of touching metal when the pump is going. Has anyone ever had this before?

    I bought it from Mocopan last November so I guess the warranty is still valid.

    Not normal- suggest that you return the machine to mocopan for a check...

    Re: Silvia loud clicking noise

    Greetings, tintub -

    Does it sound like it could be the pump hitting the splash guard below the water reservoir? The vibe pumps in these machines are mounted on rubber vibration isolators that allow some movement. And there is not a lot of clearance between the tubing/fittings and the SS splash guard.

    If this seems like a possibility, judging from the sound you hear, it is easily checked by doing a little disassembly.

    Good luck.

    Re: Silvia loud clicking noise

    If the "occasional loud clicking noise" also sounds a bit sparky, it could be a problem I had. I had this for a while after about 10 months of use. The clicking lasted for about a week or so then I smelt a bit of electrical smoke smell and the solenoid coil failed. Might be hard to tell, but does the clicking come from the lower front panel just behind where the group handle (filter holder) goes?

    When the solenoid coil fails, and you try and operate the brew switch, the pump will operate but you get no water coming out of the group. If you operate the hot water switch and open the steam knob, you will get water coming out of the steam tube. Of course this might not be the problem you are having but it seems very similar to me.

    Once the solenoid broke I got it replaced under warrantee. I agree you should report your symptoms to Mocopan for advice.

    Advice for others searching these posts in future if their solenoid coil fails out of warrantee. It is an easy part to replace yourself if you are mildly technical and are careful (there is 240V in there!)

    it would probably be a similar part to 700181-22 from Coffee Parts (Sponsor) though that is probably a commercial coil. Check with Coffee Parts. Mine was replaced with a commercial coil rather than the standard silvia one and it works fine.

    note: the solenoid failing could also just be due to clogging of the solenoid which can be corrected by dismantling the three way valve and removing obstructions. If you cant tell the cause then seek advice.

    some pics of where the solenoid coil is so you can listen for whether on not the click noise is originating in that area: http://member.newsguy.com/~jenkins/silvia/

    It is the black cube with the wires attached

    Re: Silvia loud clicking noise

    Just thought of a test. We know you hear the clicking when pumping water through the group (using the brew switch), do you also get this sound when pumping water through the steam tube?(operate the hot water switch and open the steam knob).

    If you dont get the sound in the second case, then I think it is definitely the solenoid coil about to fail as I dont think this coil operates when using the hot water switch. If you do get this sound in both cases, then it is probably not the coil and may be pump rattling as mentioned by JGG or maybe some other issue.

    Re: Silvia loud clicking noise

    thanks for the replies guys - I dropped it off at Mocopan this morning but their service guys arent in until Monday. I left a note detailing the symptoms but hadnt read these posts. Am sure they know the machine but when they call on Monday I will mention the solenoid coil. I dont think its the pump banging against something - firstly I dont see why that would suddenly happen after 10 months and secondly it just doesnt really sound like that to me.

    I havent had the problem with pumping water through the steam wand or when steaming, just with the group.

    I doubt this is relevant, but I also sometimes find a small pool of water on the left of the machine at the back. The obvious cause of this is the overflow tube that goes into the drip tray, but I make sure the drip tray is always pushed all the way to the back, also the puddle is always totally clean water. I dont spill it when filling the reservoir and its not condensation from the lid. Its a mystery... I normally just whack some kitchen towel down and soak it up but would welcome any suggestions as to what the problem is.

    It is not clear to me exactly where this pool of water is. Do you mean on the bench under the machine about where the water tank is on the left, or somewhere else?

    In my silvia, if I take my drip tray cover off, there is often a bit of condensation (or splashed water) that has built up on the black painted metal near the rear of where the drip tray goes near the solenoid overflow tube that you mentioned. I pretty much just ignore this as there is not much and it doesnt seem to rust the metal frame (the black painted metal). This always seems to be clean water too rather than the gunk that goes in the drip tray. I think it might be caused by steam (from the solenoid overflow) rather than splashing as it is clean. I expect it could be minimised by extending the solenoid overflow tube by say 8mm with a tiny bit of tubing. If you are getting an excessive amount of this splashing I suppose it could lead to a pool of water.

    Another idea. This is a long shot but do you have two tubes going into the water tank? There should be two. One tube is for taking water from the tank and the other is a return tube that occasionally returns water to the tank. If this second tube was not going to the tank you would get water leaking and it would be clean water. If you dont have two tubes in the tank, take the water tank out and look for the other one and make both tubes go into the tank.


    Otherwise I guess it is possible that there is a small leak somewhere.

    I expect you have asked the service people to look at the leak issue. If you get the machine back and you still have the pool of water happening, you could try the following if you are handy:
    - run the machine for a while till you notice the pool of water.
    - turn the power off and unplug your silvia (240V warning)
    - take out the water tank
    - remove the top four screws and take the top metal plate off
    - look around for signs of leaking. careful, as some internal parts will be hot.
    - if you find anything obvious leaks, see if you can fix it - tighten things or whatever - or send it back for repair.

    good luck,

    I had the backsplash on my silvia removed last week and definitely read that it was a parker solenoid; from memory it might have been 220V. Seems to be the same as the above-mentioned solenoid, which is found in LM Lineas as well as Rancilio S1s ... I think. It makes sense that they would use a commonly available commercial part that they have lying around in stock. Best bet is to call Pedro at Coffeeparts or Mocopan to check before replacing, though ... they run at about $80! Had some troubles with my solenoid not too long ago, but I ran a massive descale through my machine just to make sure there was no crud in there, then unplugged the machine and disconnected, then reconnected all of the wires to the solenoid. Luckilly, that did the trick.

    Cheers,

    Luca

    Re: Silvia loud clicking noise

    I got my machine back today and it was indeed the solenoid which was blocked or leaking (I heard them say both). They replaced the solenoid (black cube thing with a springy insert) with a commercial one and gave me the old one as a souvenir :D If it wasnt under warranty would cost $80 for the part and they said they would probably fit it for free (I guess only because I bought my machine from them).

    The small pool of water they said was normal, something to do with heat differences or something but nothing to worry about. They also gave me a free new spout for my rocky which had a hairline crack in it.

    Re: Silvia loud clicking noise

    Tintub are you in Melbourne or Sydney? The reason I ask is that I had the same problem recently andd Mocopan in Sydney refused to repair it under warranty as they said that the solenoid was jammed with coffee and it was my fault. I had not been regularly backflushing as I had understood that this was not recommended with Silvias.

    Re: Silvia loud clicking noise

    I might be a bit dyslexic when it comes to electrics but how the heck could you jam a solenoid with coffee?

    Will one of you more technical types please explain. *:o

    Its not the solenoid itself that gets jammed up with coffee, but rather the valve it operates that gets clogged with debris. Debris that left undealt with will eventually cause a failure of the solenoid.

    Im in Melbourne, it seems like they are a lot nicer here than at the Sydney branch. as far as I know backflushing is not recommended and probably voids your warranty (if you tell them :D)

    You have statutory rights. If it failed in a time when you could reasonably expect it not to fail then you are entitled to a repair, exchange or refund. Its your choice. Just stand your ground.

    Were you dealing with Cerebos directly or Mocopan or the place where you bought it? Cerebos are the people who do the servicing (they might own Mocopan - not sure).

    Did you have the exact same problem as mentioned above? If so, then I think that you may have just talked to someone who misdiagnosed the problem and you might need to talk to the technician directly. I have found the Cerebos people in Sydney to be very helpful by the way.

    Have you had it fixed yet? That wasnt mentioned in your post.

    Re: Silvia loud clicking noise

    Yes I paid up and had it fixed. Yep it was exactly the same problem - the people at Cerebos actually said it was the "group valve" that jammed - but no one I have talked to since really new what this meant - (Javaphile has now explained it - thanks).

    Having had dealings with Cerebos over other issues I really dony feel inclined to take the matter further as I really dont need the aggravation - all I can do is urge potential Rancilio purchasers not to buy from Mocopan/Cerebos if you are in Sydney - other Rancilio re-sellers are a much better option (eg Di Bartoli).

    I now backflush regularly (thanks to Hazel!). Re voiding the warranty if you backflush a Silvia - the tech guy at Cerebos said I should have been doing it to avoid the coffee build up. When I said I thought this was not recommended by Rancilio he said "although you didnt need to do it as often you still needed to do it". This of course was not pointed out whenI bought the machine from Mocopan in Sydney.

    Re: Silvia loud clicking noise

    I know you dont want the aggravation but if it was me theyd hear a bit more about it.
    If they dont want the warranty problems they should have told you when you bought it (and probably in writing).
    Some retailers have no idea about looking after their customers and reputations.

    At least its working again and youve learned from the experience.

    the mocopan boys in the workshop at cerebos (syd) told me its not neccessary to backflush a silvia??? only clean group head shower screen and run descale thru it occassionally?

    Re: Silvia loud clicking noise

    Sullo they told me that too but a couple of weeks ago after reading that it is ok to do it I tried it out with some detergent and pretty much forgot about it... when I brewed my next coffee I was amazed at how much better it tasted... so now Im a convert.

    In a word tt..... NO, there shouldnt be any leaks.

    If youre getting leaks on the Suction side of the Pump, then that probably means that some air is getting entrained with the water through to the high pressure side of the pump and this will cause compression pulses in the High Pressure circuit of the system (a bit like water hammer). It may also be the reason why it appears there is a leak on the discharge end of the pump too.

    First up, try to fix up the leak on the Suction end of the Pump, clean up the stains left behind and see whether this fixes the problem over time. If leaks still persist from the Discharge end of the Pump, then you will probably have to remove the screw-on fitting, remove all traces of any old Teflon Tape, apply new Tape and screw the fitting back on. Needless to say, in order to accomplish this you will have to remove the Pump from Silvia otherwise the job is rather awkward.

    All the best,
    Mal.
